Abstract Objective Appliances used in preventive and interceptive orthodontics, which are often provided to correct or intercept a specific malocclusion or habit, may be detrimental. to a child's oral health. The objective of this study was to evaluate the effect of intra oral appliance wear on the plaque index, gingival index, bleeding on probing, and on levels of salivary Streptococcus mutans. Materials and Methods A total of 60 children requiring any preventive or interceptive orthodontic treatment (appliance therapy) were randomly divided into two groups, as fixed orthodontic appliance group (n = 30) and removable appliance group (n = 30). Preoperative and post operative assessments of patients were done before and after wearing appliances. Assessment was done by determining oral hygiene status and microbiological evaluation of saliva for S. mutans count. S. mutans colonies were counted from saliva cultured on mitis-salivarius-bacitracin (MSB) agar. Statistical Analysis Data that are continuous in nature were summarized as standard deviation and mean. For “within group” comparisons, paired t-tests were used to analyze the continuous data. For “between group” comparisons, unpaired t-tests and Fisher's exact test were used to analyze the continuous data. Results Appliance treatment increases plaque and gingival indices. Plaque and gingival index changes 1 month after deployment of both fixed and removable appliances were essentially the same and statistically non-significant with p-values of 0.412 and 0.965. Bleeding on probing after insertion of both appliances was not statistically significant (p=0.423). S. mutans numbers increased following removable and fixed orthodontics. Fixed appliances had more S. mutans than removable appliances (p=0.014). Conclusion The inherent levels of these microorganisms are related with plaque accumulation due to fixed or removable appliances. Increase in the level of plaque and microorganisms after fixed and removable appliance therapy can hamper optimum oral health and thus is a concern for pedodontists. During orthodontic therapy, cariogenic pathogens should be reviewed, and to prevent cariogenic pathogens from increasing and to maintain oral hygiene during orthodontic treatment, proper recall visits, patient and parent education, and regular fluoride application are essential.

OBJECTIVES: To determine the frequency of emergencies in patients with fixed and removable orthodontic appliances at tertiary care dental hospital. METHODOLOGY: A questionnaire was designed for this descriptive cross-sectional study to be filled by the clinician (L3/L4 FCPS resident) at the end of addressing every orthodontic emergency. Sampling was done under consecutive non-probability protocols. Descriptive statistics were applied to determine the frequency of different orthodontic emergencies, and Pearson’s chi-square test was applied to determine association of emergencies with gender and etiology of emergency (patient related vs operator related). Data was analyzed on SPSS version 20. RESULTS: A total of 175 patients reported with orthodontic emergencies. The sample comprised 38.3% males and 61.7% females. Most frequent orthodontic emergency reported was deboned brackets in fixed appliances, while the most common emergency in removable appliances was traumatic PNAM. A statistically significant association (Pearson’s Chi Square=4.74, Cramer’s V=0.165, p=0.029) was seen for removable and fixed appliance emergencies with males and females. CONCLUSION: Most frequent fixed appliance orthodontic emergencies were deboned brackets while for removable appliance emergencies were trauma due to PNAM. Emergencies with removable appliances were mostly due to the operator related factors, while in fixed appliances patient related factors were dominating.

Full textAbstract:
At present, fixed orthodontic appliances treatment is extensively utilized with excellent outcome. Nevertheless, complications frequently arise following the conclusion of orthodontic treatment, predominanly relapse. Relapse refers to repositioning teeth to their pre-treatment state; its progression is stochastic, thereby rendering relapse possible for each individual. Patients who fail to wear retainers consistently will relapse of the affected teeth after orthodontic treatment. Therefore, this case report details the successful treatment of tooth relapse with a removable orthodontic appliance. A 22-year-old female patient complained of irregular alignment of her lower front teeth. The patient received two years of treatment with fixed orthodontics; however, she ceased using retainers regularly after treatment concluded. An objective examination indicated that the teeth in the upper jaw teeth remain in a well-aligned position; however, the lower jaw exhibited that tooth 32 was mesiolabiotorsiversion, tooth 33 was distolinguotorsiversion, tooth 41 was labioversion, tooth 42 was mesiolinguotorsiversion, with an overjet of 3 mm and an overbite of 2 mm. Afterward, the malposition of the lower jaw teeth was corrected with an expansion plate for a removable orthodontic appliance. Following 20 follow-up treatments over five months, the malposition of the lower jaw teeth has been corrected. As a result, it can be deduced that removable orthodontic appliances continue to be efficacious in rectifying mild malposition caused by dental relapse, thereby obviating patients' need to reapply costly fixed orthodontic appliances.

This paper demonstrates a digital manufacturing technique of a removable orthodontic appliance from an intraoral scan. An intraoral scan was made for the maxillary and mandibular arches. 3Shape Orthodontics Appliance Designer produced the virtual Hawley retainer, consisting of alloy components (Adam Clasps and Fitted Labial bow) and a base plate. The base plate design was modified to adapt to inserting the alloy components, which were combined using cold-cured acrylic. The finished Hawley retainer was assessed intraorally. The described technique emphasizes the design specifications of digitally designed and manufactured removable orthodontic appliances. A combination of additive and subtractive techniques was successfully employed to manufacture the alloy components and base plate. This novel method provides an alternative approach to manufacturing removable appliances with computer-aided design (CAD)/computer-aided manufacturing (CAM) technologies. The described process offers a precursor to digital manufacturing of other developed designs of dental appliances.

ABSTRACT Objective: To determine whether orthodontic treatment with removable aligners vs fixed orthodontic appliances is associated with a different frequency of orthodontically induced external apical root resorption (OIEARR) when genetic, radiographic, and clinical factors are accounted for. Materials and Methods: Three hundred seventy-two orthodontic patients treated with removable aligners (Invisalign) or fixed appliances were genetically screened for interleukin 1B gene (IL1B) (rs1143634), interleukin 1 receptor antagonist gene (IL1RN) (rs419598), and osteopontin gene (SPP1) (rs9138/rs11730582). Twelve clinical variables, potentially associated with OIEARR, were also considered. Subjects were divided according to the presence of radiographically determined OIEARR (>2 mm). The association between OIEARR and appliance type, and radiographic, clinical and genetic factors, was assessed using backward stepwise conditional logistic regression. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. Results: Reliability of the methods was adequate. Clinical case complexity (American Board of Orthodontics [ABO] Discrepancy Index) (OR: 1.032; 95% CI: 1.005–1.061; P = .021) and extent of incisor apical displacement in the sagittal plane (OR: 1.478; 95% CI: 1.285–1.699; P = .001) were associated with an increased OIEARR risk. After adjusting for associations between clinical/radiographic/genetic factors, there were no statistically significant differences with respect to OIEARR or type of orthodontic appliance used, whether removable aligners or fixed appliances (OR: 1.662; 95% CI: 0.945–2.924; P = .078). Only subjects homozygous for the T allele of IL1RN (rs419598) were more prone to OIEARR during orthodontic treatment (OR: 3.121; CI: 1.93–5.03; P < .001). Conclusions: A similar OIEARR predisposition was identified using either removable aligners (Invisalign) or fixed appliances.

Traditionally oral appliances i.e. removable orthodontic appliances, bite splints and snoring / sleep apnea appliances are made with alginate impressions and wax registrations. Our aim was to describe the process of manufacturing customized oral appliances with a new technique i.e. rapid tooling method. The appliance should ideally be custom made to match the teeth. An orthodontic patient, scheduled for conventional orthodontic treatment, served as a study subject. After a precise clinical and radiographic examination, the approach was to digitize the patient’s dental arches and then to correct them virtually by computer. Additive manufacturing was then used to fabricate a mould for a soft customized appliance. The mould was manufactured using stereolithography from Somos ProtoGen O-XT 18420 material. Casting material for the mould to obtain the final appliance was silicone. As a result we managed to create a customized soft orthodontic appliance. Also, the accuracy of the method was found to be adequate. Two versions of the described device were manufactured: one with small and one with moderate orthodontic force. The study person also gave information on the subjective patient adaptation aspects of the oral appliance.

Full textAbstract:
Summary. Modern protocols on providing orthodontic care of children with anomalies and secondary dento-maxillaire deformities include the use of functional- guiding and mechanically-operated orthodontic equipment based on specific clinical indications. At the same time, the issues of orthodontic treatment of dento-maxillaire anomalies complicated by dentition defects still remain controversial, as the vast majority of functionally-guiding and mechanically-operated orthodontic equipment does not provide simultaneous replacement of dentition defect, whereas methods of pediatric prosthetics are often limited by the use of claspless removable laminar prostheses. Their functional efficiency is low due to insufficient fixation and the need for periodic replacement due to the growth of jaws in accordance with the age and physiological development of a child’s body. The use of traditional fixed bridge prostheses during the period of jaws growth is unacceptable, whereas the manufacture of split bridge prostheses with an intermediate part in the form of sliding elements, movably interconnected, as well as cantilever bridges, is limited by dentition due to the removal of only one tooth. Orthodontic appliances that meet these requirements, should be used to replace dentition defects, combined with dento-maxillaire anomalies in each period of formation of the dento-maxillaire system, which determines the relevance of our research. Goal. To increase the effectiveness of comprehensive treatment of children with dento-maxillaire anomalies, complicated by dentition defects of the frontal area with the use of a prosthetic appliance of our own design. Materials and methods. To achieve this goal, we examined 115 children aged from 5 to 17 years with dentition defects of the frontal area, who applied to the Department of Orthopedic Dentistry and Orthodontics, Kyiv Medical University. Of these, orthodontic treatment was performed in 64 patients with the use of removable and non-removable orthodontic appliances, including a prosthesis appliance of our own design: «Prosthesis appliance for upper jaw expansion » Ukrainian patent for a utility model № 145538 dated 28.12.2020, which is fixed using orthodontic bands and temporary fixation cement on the second temporary molars. The appliance has a plastic base with a screw, with which, if necessary, it is possible to influence the growth of the jaw. It also has artificial teeth in the frontal area, which are connected to the base, and do not inhibit the growth of the frontal segment of the upper jaw. Results. According to the results of the research it is determined that for each period of formation of the dento-maxillaire system with dento-maxillaire anomalies complicated by dentition defects it is reasonable to apply a personalized approach when conducting psycho-emotional preparation for treatment, oral cavity sanation, placing on myogymnastic exercises and appropriate orthodontic treatment combined with pediatric prosthetics. Traditional removable and non-removable orthodontic appliances as well as appliances of our own design were used to treat this group of people. According to the results of the treatment, the use of a fixed orthodontic appliance of our own design in children of young and middle age, which restores the function of biting food, allows to replace the dentition defect and meet the aesthetic requirements of patients, as well as to conduct continuous orthodontic treatment due to impossibility to remove the appliance. Indications for the use of this prosthesis appliance is the absence of 1 to 4 front teeth with the possibility of correcting the transversal size of the jaws. Our proposed prosthesis appliance meets the requirements and is easy for patients to use. Conclusions. Indications for the use of the prosthesis appliance of our own design is the absence of 1 to 4 front teeth with the possibility of correcting of the transversal size of the jaws. The use of a non-removable prosthesis appliance of our own design in children of young and middle age, which restores the function of biting food, allows to replace the dentition defect, meet the aesthetic requirements of patients, and to conduct continuous orthodontic treatment. Key words: dento-maxillaire anomalies, dentition defect, orthodontic treatment, orthodontic appliances, prosthesis appliance.

Full textAbstract:
The purpose of the study was to increase the effectiveness of orthopedic and orthodontic treatment of children with dentition defects during the period of mixed occlusion to prevent secondary dento-maxillaire deformities. Material and methods. 47 patients aged from 6 to 11 years with dentition defects in the frontal and lateral areas were examined and treated to conduct comparative evaluation of the effectiveness of using removable and non-removable prostheses appliances in patients with dentition defects during the period of mixed occlusion. All the patients were divided into two clinical groups by the design type of a prosthesis appliance, the choice of which depended on the results of a complete clinical research taking into account the location and the length of dentition defects. For group I patients (n=29), we used removable orthodontic prostheses appliances (standard mechanically-operated appliances with artificial teeth), in areas with missing teeth, to regulate the size of upper and lower dentition and replace dentition defects. For group II patients (n=18), we used non-removable orthodontic prostheses appliances (bands with a spacer and a non-removable prosthesis appliance of our own design). At the beginning of treatment and after 3 and 6 months, the assessment of oral hygiene was conducted using Yu. A. Fedorov and V. V. Volodkina indices. Follow-up examinations of patients in both groups were conducted once a month. However, every 3 and 6 months, patients of group I (with removable prosthesis appliances) received repetitive jaw impressions and made control diagnostic models, which measured the size of a dentition defect area to monitor the treatment. The data on control measurements was compared with data obtained at the beginning of the treatment. The criteria for completion of orthodontic treatment were considered to be the regulation of the size of upper and lower dentition and the position of individual teeth, as well as the preservation of the place in the dental arch until the physiological change of prematurely lost teeth. Results and discussion. The main causes of dentition defects occurrence in patients of both groups were the following: premature removal of temporary and permanent teeth due to complications of caries – 39 patients (83.0%), the loss of teeth due to a trauma – 5 patients (10.5%). Dentition defect was caused by adentia – in 2 people (4.3%), by retention – in 1 person (2.1%). We determined that 30 people (63.8%) had defects of the upper jaw, which was the most prevailing dentition defects. Dentition defects in the lateral areas were recorded in 32 people (68.1%). The largest number of dentition defects was of short size – 29 (61.7%). To restore the integrity of the dentition, we made 29 removable prostheses appliances with artificial teeth for group I patients, 9 (31.0%) of them served to replace dentition defects of the frontal area and 20 (69.0%) replaces dentition defects of the lateral area. In order to replace the dentition defect and preserve the place in the dental arch, we made 18 non-removable prostheses appliances for group II patients, 6 (33.3%) of them were of our own design to replace the dentition defect in the frontal area, and 12 (66.7%) replaced teeth gap bands with a spacer for the lateral one. Based on the analysis of these indicators in people with dentition defects who used removable and non-removable appliances, we can conclude, that there is a clear connection between the impact of orthodontic appliances on oral hygiene, depending on its type. The negative dynamics of changes in the hygiene index according to Fedorov-Volodkina in patients with non-removable prostheses appliances can be explained by the deterioration of oral hygiene conditions due to the design features of the appliances and the inability to remove the appliance yourself. Therefore, the use of non-removable appliances requires additional hygienic measures. Removable appliances had almost no effect on the state of oral hygiene, but worked less predictably by reducing the time of their active action in the oral cavity. If children refused to wear removable prostheses and prosthesis appliances, there quickly developed secondary dento-maxillaire deformities, which over time became more stable, and pathological changes were more significant. In group I patients, 6 months after the start of treatment with removable prostheses appliances, the shortening of dentition defects was detected in the frontal area by 1.3±1.1 mm and in the lateral area by 1.2±0.9 mm. Negative changes in the length of the dentition defect in patients of group I before treatment and after 6 months are specifically connected with irresponsible attitude to treatment. Not all patients in this group fully wore removable prostheses appliances, and some of them did not wear at all. Conclusion. Our research showed that removable orthodontic appliances for replacement of dentition defects and prevention of secondary dento-maxillaire deformities could be used in patients of different ages, their special effectiveness was observed in pediatric-age patients, however, only in those who responsibly followed the recommendations of an orthodontist. The use of non-removable orthodontic appliances for replacement of dentition defects and prevention of secondary dento-maxillaire deformities is a more rational choice of dental prosthesis. The prosthesis appliance for the upper jaw developed by us doesn’t inhibit the growth of the jaw, meets all the esthetic and functional requirements applied to these appliances. During treatment with non-removable appliances patients cannot control the time when the appliance “works”, which leads to a more predictable result of treatment

It is of interest to compare two myofunctional appliances (frankal appliance and twin bloc) and two fixed orthodontic appliances (Power Scope and Forsus) in management of class II div 1 malocclusion. A total of 56 Class II division 1 malocclusion patients indicated for treatment with myofunctional appliances and fixed functional appliances were randomized. They were equally divided among frankal appliance (n=14), twin block appliance (n=14), Power Scope (American Orthodontics) (n=14), Forsus (3M Unitek Corp) groups (n=14). Skeletal and dentoalveolar effects of all appliances were compared. SNB increased remarkably by 4.2° in the Twin block group and it was high among all treatment groups. There was a significant decrease in vertical dimensions (SN-GoGn) in the Twin block (p = 0.002). Early treatment of Class II due to mandibular retrusion with Twin block functional appliance is recommended due to its favorable skeletal effect.

Currently, wide arrays of fixed functional appliances are available for the correction of Class II malocclusion. The orthodontist must choose from these appliances depending on the mechanics, efficiency, and cost of the appliance. Fixed functional appliances may reduce the individual visits and hence the cost as compared to the removable appliances. Additionally, it may save the clinician’s chair time. This report discussed the in-house laboratory fabrication and clinical procedure of customized fixed functional appliances by utilizing the readily available dental materials in the orthodontic clinical setting.

Abstract Objective: To compare the periodontal status of adults treated with fixed buccal orthodontic appliances vs removable orthodontic aligners over 1 year of active therapy. Materials and Methods: The study population consisted of 42 subjects; 22 treated with fixed buccal orthodontic appliances and 20 treated with removable aligners. Clinical indices recorded included: plaque index (PI), gingival index (GI), bleeding on probing (BOP), and probing pocket depth (PPD). Plaque samples were assessed for hydrolysis of N-benzoyl-DL-arginine-naphthylamide (BANA test). Indices and BANA scores were recorded before treatment and at 6 weeks, 6 months, and 12 months after initiation of orthodontic therapy. Results: After 6 weeks, only mean PPD was greater in the fixed buccal orthodontic appliance group. However, after 6 months, the fixed buccal orthodontic appliance group had significantly greater mean PI, PPD, and GI scores and was 5.739 times more likely to have a higher BANA score. After 12 months, the fixed buccal orthodontic appliance group continued to have greater mean PI, GI, and PPD, while a trend was noted for higher BANA scores and BOP. Conclusions: These results suggest treatment with fixed buccal orthodontic appliances is associated with decreased periodontal status and increased levels of periodontopathic bacteria when compared to treatment with removable aligners over the 12-month study duration.

Abstract Objective: To assess the prevalence, intensity, and extent of the impacts on daily performances related to wearing different types of orthodontic appliances. Materials and Methods: A total of 1657 students, 15 to 16 years old, were randomly selected from those attending all secondary schools in Bauru, São Paulo, Brazil. Only those wearing orthodontic appliances at the time of the survey were included. Face-to-face structured interviews were done to collect information about impacts on quality of life related to wearing orthodontic appliances, using the Oral Impact on Daily Performances (OIDP). Adolescents were also clinically examined to assess the type of orthodontic appliance they were wearing. Comparisons, by type of orthodontic appliance and covariables, were performed using nonparametric statistical tests. Results: Three hundred fifty-seven adolescents (36.1% boys and 63.9% girls) undergoing orthodontic treatment participated in the study. The prevalence of condition-specific impacts related to wearing orthodontic appliances was 22.7%. Among adolescents with impacts related to wearing orthodontic appliances, 35.8% reported impacts of severe or very severe intensity and 90.1% reported impacts on only one daily performance, commonly eating or speaking. The prevalence, but not the intensity or the extent, of condition-specific impacts differed by type of orthodontic appliance (P = .001). Conclusions: One in four Brazilian adolescents undergoing orthodontic treatment reported side effects, specific impacts on daily living, related to wearing orthodontic appliances. Such impacts were higher among adolescents wearing fixed rather than removable or a combination of fixed and removable orthodontic appliances. This information could help to inform patients about the frequency and intensity of sociodental impacts during the course of their treatment.

Orthodontic treatment is performed by moving the malposition teeth into a good position in the dental arch with a removable or fixed orthodontic appliance. In this regard, the removable orthodontic appliance has an active component to transmit the orthodontic force that will result in orthodontic tooth movement. The orthodontic force used must be optimal in the sense of being able to produce tooth movement without causing side effects that endanger the periodontal tissue. It is necessary to activate the active components of the appliance, which in orthodontic treatment can be done several times until the desired tooth position is achieved. This study aims to explain the differences in orthodontic force in activating active components of removable orthodontic appliances. The research method was an experimental laboratory. A total of 24 removable orthodontic appliances used in this study were divided into two groups. The first group has a Z spring or single cantilever spring active component, and the other group has a labial bow. Each active component is activated by opening the loop by 1mm, 1.5mm, and 2mm, and in each activation, the magnitude of the force generated is measured using a tension gauge. Data analyzed by Mann Whitney (p<0.05). The result showed different activations carried out in this study resulted in significantly different forces with p=0.029. The force generated in each activation increases as the loop opening increases. Based on that results, it can be concluded that there is a significant difference in the force magnitude generated by the activation of the removable orthodontic appliance active component.

To ensure that the results of fixed orthodontic therapy are maintained and do not relapse, it is crucial to retain and preserve the treatment outcomes. Retention is an essential aspect of orthodontics and can be viewed as the final stage of treatment. It is necessary to maintain an optimal esthetic and functional occlusion following orthodontic therapy.
Aim : The objective of the article is to acknowledge the significance of maintaining the outcomes of orthodontic therapy and to assess the various techniques used to fabricate fixed and removable appliances for retention.
Materials and Methods:
The present article evaluates the different protocols for lingual fixed retainers, as well as removable retentive appliances such as Hawley, Begg, and vacuum-formed retainers (VFR). Removable appliances have been used for retentive purposes for a long period of time. Bonded fixed retainers were introduced in the 1970s, and they have several advantages over removable retentive appliances, such as better esthetics, the absence of patient cooperation, and suitability for lifelong retention. Fixed retainers can be of conventional or digital type. Conventional fixed retainers can be fabricated and attached directly or indirectly to the teeth using a transfer tray. Moreover, bonded retainers can now be digitally manufactured using computer-aided design and computer-aided manufacturing (CAD-CAM).

Background: Patient undergoes orthodontic treatment with removable and fixed appliances will usually complaint of pain and discomfort. The level of pain and discomfort experience by patient will determined the cooperation and compliance towards the treatment. This study explores the perception of pain and type of discomfort experience by patients when undergoes orthodontic treatment.
Material and method: This cross-sectional study involve a set of questionnaires regarding patient social demographic and factors contributing to pain and discomfort among patients with removable and fixed appliances.
Result: This study shows that the most common discomfort experienced by patients with removable appliance are increased in saliva flow, interferes with mastication and altering speech. Apart from that, ulcers, pain in the mouth and appliance breakages are the most common pain experience by the patients with fixed appliances.
Conclusion: In conclusion, majority of patients will experience some form of pain and discomfort during orthodontic treatments. Thus, information regarding pain and discomfort during orthodontic treatment should be clearly convey during the first initial appointment to prepare patient mental and physically.

Full textAbstract:
Background: Central diastema refers to an anterior spacing between maxillary central incisors and malposition of the individual teeth refers to the teeth being crowded in the upper and lower jaws. There are many causative factors that contribute to the occurrence of these two cases, such as heredity, frenulum deformity, gender, and bad habit. Removable orthodontic appliances are devices that can be used in cases of mild malocclusion. Objective: The purpose of writing this case report is to show that removable orthodontic appliances are the first choice for dentists. Case: A 23-year-old male patient came to UMY Dental and Oral Hospital (RSGM UMY) complaining that his front teeth had spacing and some irregularly arranged teeth. The patient felt uncomfortable with the condition of the teeth. Patient complaints are felt as early as 3 years ago. One year ago, had already used a removable orthodontic appliance and after the treatment is finished then used a retainer but only for 1 month because the retainer is missing. The case of this patient is class I Angle with central diastema and malposition of individual teeth. Case Management: Treatment is carried out using removable orthodontic appliances. The appliances component uses a simple spring on tooth 31 and 41, retentive component uses Adam’s clasp on teeth 16, 26, 36 and 46. Labial arch with a U loop in between canine and first premolar. Conclusion: The removable orthodontic appliance should be used to correct cases of mild malocclusion such as a central diastema with mild malposition of the individual teeth.

Background (1): Removable orthodontic appliances may favor plaque accumulation and oral microbe colonization. This might be associated with intraoral adverse effects on enamel or periodontal tissues. The proposed systematic review was carried out to evaluate qualitatively and quantitatively the microbiological changes occurring during orthodontic therapy with removable orthodontic appliances. Methods (2): PubMed, Cochrane Library, Embase, Web of Science, Scopus, Ovid Medline, and Dentistry and Oral Sciences Source were searched. The research included every article published up to January 2020. The Preferred Reporting Items for Reporting Systematic reviews and Meta Analyses (PRISMA) protocol and the “Swedish Council on Technology Assessment in Health Care Criteria for Grading Assessed Studies” (SBU) method were adopted to conduct this systematic review. Results (3): The current study has a moderate evidence, demonstrating that removable appliances do influence the oral microbiota. Significant alterations occur just 15 days after the beginning of therapy, independently from the type of appliance. Furthermore, the levels of oral pathogens decrease significantly or even returned to pre-treatment levels several months later the therapy end. Conclusions (4): This review suggests that orthodontic treatment with removable appliances induces changes to oral microflora, but these alterations might not be permanent.

Relevance. The present article provides data regarding changes in the oral cavity during orthodontic tratment with custom-made removable appliances. Purpose. To study the condition of the oral cavity in children aged 7-12 with dentoalveolar abnormalities during treatment with removable orthodontic appliances.Materials and methods. 110 patients aged 7-12 were examined in Nakhodka, Russia. Group I – control (34 subjects) with no dentoalveolar pathology. Group II – children with dentoalveolar pathology (74 subjects), undergoing orthodontic treatment. Besides clinical examination the following laboratory tests were taken, namely: saliva viscosity, saliva PH, saliva buffer capacity, microcrystallography of saliva. Type III prevailed in 60% of cases. Results. Caries intensity during orthodontic treatment was detected to increase up to 8.32 ± 0.28 in comparison with control group 6.57 ± 0.22 (p < 0.05). Hygiene rate decreased in experimental group to 2.8 ± 0.08, in comparison with controls – 1.40 ± 0.02 (p < 0.05). Salivary PH decreased during orthodontic treatment. Microcrystallization type III of saliva prevailed in 60% of cases.Conclusions. The study revealed strong relationship between orthodonotic treatment with removable appliances and physicochemical properties of mixed saliva r = 0.95 (p < 0.05). Appropriate approach and timely preventive measures can help correct oral condition in orthodontic treatment. Despite changes in oral fluid composition, esthetic and functional result of treatment with orthodontic customized removable appliances was high.

Orthodontic appliances modify the local environment of the oral cavity, increase the accumulation of dental plaque, and affect the condition of the gingiva. The aim of this study is assessment of Brazilian propolis toothpaste’s effect on plaque index (PLI) and gingival index (GI) in patients with CL/CLP treated using orthodontic appliances in the 35-day study period. The study population included 96 patients of an Orthodontic Outpatient Clinic, ACSiMS in Bytom. All the patients participated in the active phase of orthodontic treatment using buccal multibracket appliances or removable appliances. During the first examination, each patient was randomly qualified to the propolis group or control group. A statistically significant decrease in GI and PLI in the entire propolis group (P<0.01) was shown during repeated examination. Insignificant change in GI was in the entire control group during the repeated examination compared to the baseline. Similar result was obtained in patients treated with multibracket and removable appliances. The orthodontic appliance type did not affect the final dental plaque amount and gingival condition in patients using the propolis toothpaste. These results may be clinically useful to improve prevention and control oral infectious diseases during orthodontic treatment patients with oral cleft.

Anterior crossbite is relatively a common presentation in the mixed dentition stage. If left untreated, it can lead to a host of problems and may complicate future orthodontic treatment. One of the major difficulties in performing anterior crossbite correction in young children is treatment compliance. In most cases, poor compliance is due to the unacceptability of the removable appliance used. This article describes three cases of successful correction of anterior crossbite of patients in mixed dentition using short-span wire-fixed orthodontic appliances. This sectional appliance provides an alternative method of correcting anterior crossbite of dental origin and offers many advantages compared to the use of removable appliances.

Commercialisation has had profound effect on how dental services are provided. Many of the appliances and treatment modalities are market driven at exorbitant prices leaving the lower socioeconomic status people stigmatized. This paper is an attempt to revisit the simple removable appliance, providing limited corrective orthodontics in cases of mild to moderate malocclusion, which can be a justified as an alternative to complex appliances. This paper presents a case of a young girl with single anterior tooth crossbite, which was corrected by a removable appliance. An expansion appliance incorporating z-spring and posterior bite plane was used to correct the malocclusion. These appliances can be easily fabricated, are cost effective and are very helpful in treating the masses in areas with minimum support like villages.

Orthodontic appliances promote the accumulation of biofilm in the oral cavity and increase counts of Streptococcus mutans (S. mutans). However, there are few comparative studies of the effects generated by the interaction of saliva and microorganisms in absence and presence of orthodontic appliances. Aim: The aim of this study was to determine the S. mutans colony-forming unit count (CFU/mL) in participants with and without fixed orthodontic appliances. Materials and Method: It was an observational cross-sectional study on 21 participants, all over 18 years of age, non-smokers, without removable oral appliances, who had not been under antibiotic treatment within the previous three months. Sociodemographic variables, oral hygiene habits, S. mutans CFU/mL count, and salivary pH were assessed. Saliva samples were collected, and the data was analyzed using Fisher’s exact and Kruskal Wallis tests. A p-value <0.05 was considered statistically significant. Results: Fourteen (66.7%) of the participants were female; average age was 20.4 ± 2.2 years. The group without fixed orthodontic appliances had the highest salivary S. mutans CFU/mL count (Me: 56.0×103, IQR: 9.2×103 - 75.5×103), but there was no statistically significant difference between groups (p=0.7459). There was a statistically significant difference in salivary pH, with the metal orthodontic appliance group having the lowest pH (p=0.0478). No statistically significant difference in salivary S. mutans CFU/mL count was found between groups. Salivary pH was lower in the group with metal appliances than in the groups with non-metal appliances and without appliances. Keywords: streptococcus mutans - saliva - orthodontics - mouth

Summary. Today, the need for orthodontic treatment of anomalies of tooth position and occlusion is constantly growing. In the practice of orthodontics use a variety of orthodontic appliances. The most widely used non-removable appliances that allow treatment of adult patients. However, dentists often intensify orthodontic appliances to speed up the end of treatment result. Unfortunately, this has a very adverse effect on periodontal tissues. This article analyzes the data of the dental literature on the impact of orthodontic treatment on the hard tissues of the teeth and, especially, on the periodontium. The main factors of periodontal damage during orthodontic treatment are determined. An analysis of possible areas of prevention of periodontal disease during orthodontic treatment was presented. Key words: orthodontic treatment, oral cavity, periodontium, periodontal lesions, prevention.

Abstract A survey of 468 Gracie Seven students and 437 parents in the North Brisbane region was undertaken to determine perceptions of orthodontic appliances. Based on responses to statements on the survey, a Perception Score was created for both students and parents in relation to both fixed and removable appliances. Both students and parents had more negative perceptions of fixed appliances than of removable appliances. Fixed appliances were perceived to attract more teasing, to cause more problems in the maintenance of oral hygiene and to be more painful than a removable plate. Respondents also felt that children would have to be more careful about what they eat when wearing fixed appliances. Approximately forty per cent of students and parents did not know whether teeth could be damaged by orthodontic appliances nor whether the appliances would cause discomfort. Parents had significantly more negative perceptions of both types of orthodontic appliances than did the students. The Perceptions scores were not significantly influenced by whether the students attended a private or public sector dentist, the frequency of dental visits, any history of orthodontic treatment, nor by the parents’ level of education and their occupations. A forewarning about experiences of orthodontic appliances would better prepare patients and assist operators in providing the community with a more comprehensive orthodontic service.

Salah satu pertimbangan dalam menentukan alat ortodontik yang akan digunakan adalah biaya. Alat ortodontik lepasan dipilih karena memerlukan biaya yang lebih rendah dibanding dengan alat ortodontik cekat. Perawatan ortodontik dengan alat lepasan sulit dilakukan jika disertai dengan pencabutan satu atau beberapa gigi posterior. Pasien perempuan usia 23 tahun, mengeluhkan gigi rahang atas maju dan gigi rahang bawah berjejal. Pemeriksaan objektif menunjukkan protrusif rahang atas, crowding rahang bawah, palatal bite, disertai kehilangan gigi 46. Maloklusi Angle Kelas II divisi 1 tipe dentoskeletal, hubungan skeletal klas II, protrusif bimaksilar, bidental protrusif, overjet 7,2 mm, crowding, palatal bite, dan kebiasaan bernafas melalui mulut. Perawatan menggunakan kombinasi alat semi-cekat pada rahang bawah dan alat lepasan pada rahang atas. Alat semi-cekat digunakan untuk space clossing bekas pencabutan gigi 46. Terjadi space closing bekas pencabutan gigi 46 setelah 6 bulan perawatan. Overjet berkurang menjadi 4 mm dan overbite 2,7 mm setelah 1 tahun perawatan. Kombinasi alat semi-cekat pada rahang bawah dan alat ortodontik lepasan pada rahang atas efektif untuk koreksi maloklusi Angle Klas II divisi 1 dengan kehilangan gigi 46 pada pasien ini. ABSTRACT: Orthodontic Treatment Using Semi-Fixed Appliances with Partial Edentulous 46. Cost is one of the considerations in determining the use of orthodontic appliances. Removable orthodontic appliance is chosen because it is less costly than fixed orthodontic appliances. It is difficult to use removable orthodontic appliances to treat a missing one or more posterior teeth case. A 23 year old female patient had a chief complaint of crowding in lower anterior teeth and forwardly placed upper anterior teeth. Her objective examination shows protrution of upper teeth, crowding in the lower arch, palatal bite, and partial edentulous of 46 tooth. It was Angle Class II division 1 dentoskeletal malocclusion, skeletal class II, bimaxillary protrusion, bidental protrusion, overjet 7,2 mm, crowding, palatal bite, and mouth-breathing habit. The treatment used a combination of semi-fixed orthodontic appliances in the lower arch and removable appliances in the upper arch. The semi-fixed orthodontic appliances were used on space closing of partial edentulous 46. The partial edentulous 46 was closed after 6 months of treatment. The overjet was reduced to 4 mm and overbite 2,7 mm after one year of treatment. The combination of semi-fixed orthodontic appliances in the lower arch and removable appliances in the upper arch generate a good result to correct Angle Class II division 1 malocclusion with partial edentulous 46.

ABSTRACT Objective: To compare patients’ perceptions of fixed and removable appliance therapy for correction of anterior crossbite in the mixed dentition, with special reference to perceived pain, discomfort, and impairment of jaw function. Material and Methods: Sixty-two patients with anterior crossbite and functional shift were recruited consecutively and randomized for treatment with fixed appliances (brackets and archwires) or removable appliances (acrylic plates and protruding springs). A questionnaire, previously found to be valid and reliable, was used for evaluation at the following time points: before appliance insertion, on the evening of the day of insertion, every day/evening for 7 days after insertion, and at the first and second scheduled appointments (after 4 and 8 weeks, respectively). Results: Pain and discomfort intensity were higher for the first 3 days for the fixed appliance. Pain and discomfort scores overall peaked on day 2. Adverse effects on school and leisure activities were reported more frequently in the removable than in the fixed appliance group. The fixed appliance group reported more difficulty eating different kinds of hard and soft food, while the removable appliance group experienced more speech difficulties. No significant intergroup difference was found for self-estimated disturbance of appearance between the appliances. Conclusions: The general levels of pain and discomfort were low to moderate in both groups. There were some statistically significant differences between the groups, but these were only minor and with minor clinical relevance. As both appliances were generally well accepted by the patients, either fixed or removable appliance therapy can be recommended.

Background: Anterior crossbite is a common malocclusion whose prevalence vary from country to country. It is around 6-8% in India. Aim & Objective: To evaluate the effectiveness of fixed versus removable orthodontic appliances in correction of anterior crossbite in the mixed dentition. Material & Methods: A sample size of 75 subjects were selected on differential selective criteria with history of no previous orthodontic treatment, mixed dentition, anterior crossbite with moderate space discrepancy (< 3mm), non- extraction orthodontic mechanotherapy with ANB > 0°. A written consent was signed. Treatment with two parallel mode was designed, either with a removable appliance with springs or a fixed appliance with orthodontic brackets. To standardize the design for evaluation "Randomized Controlled Trials" (RCTs) were applied and parameters like rate of success, treatment duration, pre & post treatment differences in the overjet, overbite and arch length were accessed. Results: The treatment was successfully completed in all the patients by both the treatment modalities. Method Error Analysis (MEA) & Statistical Package for the Social Sciences (SPSS) were used for statistical analysis. SPSS significantly showed the average treatment time by the fixed appliance was comparatively less (1.4 months, P < 0.05). Increase in arch length and overjet in both treatment modalities were recorded, but it was significantly higher in fixed mechanotherapy (P < 0.05 and P < 0.01). Conclusion: Both, fixed and removal orthodontic appliances can successfully treat anterior crossbite in mixed dentition with short- term orthodontic treatment.

Abstract Objectives: To evaluate the influence of Fixed (FOA) and Removable Orthodontic Appliances (ROA) on oral Candida colonisation. Methods: A search for articles published in the English language until September 2021, was carried out using Pubmed, Scopus and Web of Knowledge databases and by applying the search terms “orthodontic” OR “orthodontics” OR “fixed appliance” OR “removable appliance” OR “bracket” OR “removable aligner” AND “Candida” OR “Candidiasis” OR “Candidosis” to identify all potentially relevant human studies. After the removal of duplicate articles and data extraction according to the PICOS scheme, the methodological quality of the included papers was assessed by applying the Swedish Council on Technology Assessment in Health Care Criteria for Grading Assessed Studies (SBU). Results: The initial search identified 533 articles, 157 of which were selected by title and abstract. After full-text reading, sixteen articles were selected. The evidence quality for all the studies was moderate. Conclusions: ROA induced a temporary increase of Candida counts from the early stage of treatment but which returned to the pre-treatment level after ROA removal. Contrasting results were reported for FOA treatment which promoted the oral colonisation of non-albicans species, although the most prevalent species was Candida albicans in both groups. This review should be interpreted with caution because of the number, quality, and heterogeneity of the included studies.

The pretreatment and post-treatment study casts and records of 156 completed fixed appliance and removable appliance cases were analysed, and the influence of various factors on the standard of result, as measured by the change in PAR score produced by treatment and the duration of treatment, was assessed. For the purpose of analysis the sample was divided into two groups; a two-arch fixed appliance group (n = 81) and a removable/mini fixed appliance group (n = 75). Multiple regression procedures were carried out separately for both groups, first, with all gathered data and, secondly, with only information which would be known at the start of treatment. For fixed appliances the initial PAR score was consistently an influential variable on change in PAR score and duration of treatment. Patient compliance, the need to extract a permanent first molar and the presence of an anterior crossbite were also important. The initial PAR score also explained much of the variation in change in PAR for removable/mini fixed appliances, but generally, regression models for this group were less well fitting.

Full textAbstract:
The achievement of aesthetic, functional occlusion should not mark the end of the orthodontic intervention. To prevent relapse, retention needs advance planning, and may vary in duration. This review aims to present and comment on the available means of retention. The ever-popular, passive Hawley-like removable appliances are credible in maintaining the desired occlusion. Modifications are the removable appliance Wrap Around, having the labial archwire extending to the premolars; the translucent retainer, Astics, a unique aesthetic Hawley-type device; and the reinforced removable retainer, which features a metallic grid reinforcing the acrylic base. Vacuum-formed retainers are easy to fabricate and are readily prescribed. By contrast, fixed retainers are made of orthodontic wire and composite resin bonded on the lingual or palatal surfaces of the anterior teeth. Patient-related variables need evaluation to select the appropriate retainer, while patients ought to realize the importance of retention and comply with offered guidance. Overall, the orthodontist is responsible for keeping the patient informed on the properties and the duration of retention, even before starting active orthodontic treatment.

Objectives: Estimating patient compliance during orthodontic treatment cannot be overemphasized as timely and successful outcome of orthodontic treatment is dependent on it. This study assessed patients' compliance to orthodontic reviews at a tertiary care orthodontic clinic as well as explored various factors that may influence review attendance.Materials and Methods: Data were collected retrospectively from 133 patients' case notes as well as the clinic daily attendance records. Socio-demographic data and type of appliance used by patients was extracted. The pattern of punctuality (in days) to clinic attendance as prescribed by the managing orthodontist was also ascertained. Data were analysed using the SPSS version 22. Level of significance was set at p<0.05.Results: The mean age was 14.65 ± 5.98 years. Sixty-two (46.6%) patients were males while 71(53.4%) were females. Sixteen patients (12%) had removable appliances, 116(87.2%) had fixed appliances while only one person (0.8%) had both fixed and removable appliances. Eighty (60.2%) attendees were resident within the state of the clinic's location while 53 (39.8%) resided outside the state. At the first review visit after treatment commenced, 92(69.2%) presented on time for review while 41 (30.8%) defaulted with a mean lag time of 49.0±49.0 days before presenting at the clinic. The total default time varied significantly with the number of visits and length of treatment time (p<0.001).Conclusion: Rate of default to orthodontic reviews was found to increase gradually from the 2nd visit and imparted negatively on treatment time.

Full textAbstract:
Background: In the oral cavity there are countless microorganisms, about 40% of which are Candida albicans as normal flora. The use of removable orthodontic appliances in the oral cavity greatly inhibits cleanliness and increases the number of retentive areas in the oral cavity resulting in risk factors of increased C.albicans. Binahong leaves contain many active compounds that are antimicrobial. Objective: To determine the effect of binahong leaf extract in inhibiting the growth of C.albicans in patients using removable orthodontic appliances. Method: Laboratory experimental research was conducted with the design of the posttest only control group design involving 5 samples of removable orthodontic appliances which were swabbed to obtain C.albicans, then each tested with binahong leaf extract concentrations of 10%, 30%, 50%, 70% and the control group. Next is the inhibitory test. Results: The greater concentration of the Binahong leaf extract, the greater the diameter of the resistance. Conclusion: Binahong leaf extract has an effect on inhibiting the growth of C.albicans in patients using removable orthodontic appliances.

Full textAbstract:
Treatment of complex malocclusion poses a challenge for the orthodontist because of its multifactorial aetiology. Class II malocclusion is the most frequently encountered and treated malocclusion in orthodontic practice and affects approximately 14.6 % of the North Indian population.1 A common reason for Class II malocclusion is mandibular skeletal retrusion which is the most common characteristic, as reported by McNamara.2 This can be caused by genetic or hereditary factors. When evaluating treatment options for Class II patients, the extent of the skeletal discrepancy and the skeletal maturity of the patient needs to be considered. Treatment may range from dental compensation including camouflage with extractions to surgical procedures targeted at moving the jaw at fault. In growing patients, growth modification with functional appliances offers an intermediate treatment option. Functional appliances are basically of two types; Removable and Fixed. Removable functional appliances such as Activator, Bionator, Frankel Function regulator and Twin Block appliance change Class II relationship by the transmission of soft tissue tension to the dentition. Treatment success with these appliances relies heavily on patient compliance. Therefore, in non-compliant patients, fixed Class II correctors in conjunction with fixed orthodontic appliances are the best choice.3 Fixed functional appliances generate continuous stimuli for mandibular growth without break and permit better adaptation to functions like mastication, swallowing, speech and respiration.1 The Herbst fixed functional appliance has been used routinely for Class II patients and has undergone many design variations over time.4 The AdvanSync2 Class II corrector is a recently introduced fixed functional appliance. It has a much smaller size than the conventional Herbst appliances, is easier to place, activate and remove and most importantly, can be used in conjunction with full-arch fixed appliances throughout.3 Here we describe a case report of a patient treated with the AdvanSync2 Class II corrector and the findings observed in the sagittal and vertical dimensions

Abstract : Treatment of class II malocclusion often require maxillary molar distalization. Some of the cases can be treated by non-extraction treatment modalities such as headgear, removable appliances, and intraoral distalizers such as the Pendulum appliance, Distal Jet, and Jones Jig. Anchorage loss from proclination of anterior teeth, distal tipping and increased overjet are major concerns with most of these appliances; some also require active patient compliance22.

Introduction: Gaining space in malocclusion cases using expansion plate removable orthodontic appliances. Depression is a mental health disorder that is treated with antidepressants. There is a correlation between a history of long-term antidepressant medication use and orthodontic treatment. Case: A 21-year-old female patient with a history of antidepressant medication complained of slightly advanced maxillary front teeth and crowded mandibular front teeth. Clinical examination revealed the first permanent molar relation Angle Class I modified Dewey type 2 malocclusion with malposition of individual teeth. Arch discrepancy analysis showed a space deficiency of 4 mm in the maxilla and 2.85 mm in the mandible. Case Management: The first stage used a removable orthodontic appliance for maxillary and mandibular expansion plates to obtain space deficiency. The expansion results showed that the maxillary dental arch was successfully expanded by 4.52 mm and the mandibular by 4 mm. Discussion: The slow-type expansion plate functions to expand the dental arch. Conclusion and Suggestion: Expansion plate removable orthodontic treatment effectively gains space in patients with a history of antidepressant drug use. Patients' cooperativeness in wearing the appliance influences the expansion plate removable orthodontic appliance treatment result.

The success of orthodontic treatment, particularly with removable orthodontic appliances not only relies on theexpertise of the clinician, but also highly depends on the patient's own. It is necessary to know the extent of thesuccess rate of an orthodontic treatment. Assessment of malocclusion severity and treatment outcome has become avery popular object of research conducted by the PAR index. This study aims to determine the success rate oforthodontic treatment with removable appliances based on PAR Index. The research was carried out on March-May2011 with samples of patients dental models who had completed orthodontic treatment in the year 2008-2011 at theDepartment of Ortodonsia RSGMP UNHAS. Sixty six pairs of dental models fulfilled the inclusion criteria and therules of PAR Index. Percentage change in PAR score obtained by 35% in the assessment with no weighted and 36%was assessment by weighted. This results showed the level of orthodontic treatment success include into thecategory of "no change", but with a trend into the category of "a change "with a significant value ρ = 0.000 (ρ <0.05). It was concluded that there was occlusion improvements in orthodontic treatment with removable appliance,although very low and therefore need evaluation and improvement of governance maintenance carried out.

Full textAbstract:
Fixed orthodontics is now widely used by the community, but people often do not realize the risks of using fixed orthodontic appliances that cause oral hygiene problems. The biggest challenge to fixed orthodontic use which leads to problems regarding proper oral hygiene during this treatment is due to the components of the orthodontic appliance. The use of orthodontic appliances among adolescents, especially at the age of 14-17 years, is no longer just a treatment need but has become a lifestyle demand. This study aims to determine the level of knowledge about dental and oral hygiene in fixed orthodontic users at SMAN 1 Rancaekek. This research is descriptive quantitative. Sampling of this research was done by purposive sampling. The way this research works is by giving questionnaires to respondents. The results of this study showed that 34 students used orthodontic subjects where 25 students used fixed orthodontics and 9 students used removable orthodontics. On dental and oral hygiene knowledge, as many as 16 people (64.0%) had good knowledge, 5 subjects had sufficient knowledge (20.0%), and 4 subjects had poor knowledge (16.0%). Behavior of good knowledge as many as 2 people (8.0%), subjects who have moderate knowledge as many as 7 people (28.0%), and subjects who have poor knowledge as many as 16 people (64.0%). It was concluded that knowledge of dental and oral hygiene was categorized as good and knowledge of behavior was classified as poor.

Full textAbstract:
Background: The benefits of interceptive orthodontic treatment have always been a subject of much debate, and it is understandable that clinicians are confused about how to advise parents of potential interceptive orthodontic patients. Objective: The aim is to study the treatment outcomes of interceptive orthodontics associated with different appliances. Demographic information on patients presenting for interceptive treatment, prevalence and types of dental conditions treated, types and frequency of appliances used, treatment duration and the number of visits taken were also investigated. Methods: This study involved analyzing records of interceptive orthodontic patients seen at the National Dental Centre Singapore from January 2011 to December 2017. Treatment outcomes were divided into success, improvement and failure according to pre-determined treatment objective parameters. Results: A total of 1324 patient records (654 females, 670 males) were studied, with an average age of 10.6±1.9 years. The most common dental condition seen was the anterior crossbite while the most common interceptive orthodontic appliance used was the bite plate. Average treatment duration was 10.8±6.8 months (9.8±9.2 visits) for fixed appliances, 7.5±6.5 months (6.9±3.4 visits) for removable appliances and 10.8±3.2 months (12.6±3.3 visits) for a combination. Interceptive orthodontic treatment had an overall success rate of 75.5%, improvement rate of 9.5% and failure rate of 15.0%. The most common reason for failure was attributed to non-compliance. Conclusion: The data above shed light on interceptive orthodontic treatment in an Asian population and gives useful information for primary care clinicians to provide for concerned parents.

The contribution describes the effect of the fixed and removable orthodontic appliances on spectral properties of emotional speech. Spectral changes were analyzed and evaluated by spectrograms and mean Welch’s periodograms. This alternative approach to the standard listening test enables to obtain objective comparison based on statistical analysis by ANOVA and hypothesis tests. Obtained results of analysis performed on short sentences of a female speaker in four emotional states (joyous, sad, angry, and neutral) show that, first of all, the removable orthodontic appliance affects the spectrograms of produced speech.

The purpose of this study was to analyze the effect of orthodontic treatment with removable appliances on the growth of Candida spp. in children undergoing orthodontic treatment. The study included 60 patients of equal numbers as to gender from the orthodontics department of the Pomeranian Medical University in Szczecin, Poland. All patients were aged 6–12 years and were qualified for orthodontic treatment with removable appliances. The following examinations were performed on the day of treatment initiation (T1) and 6 months after the start of treatment (T2); a collection of oral swabs for culture on Sabouraud’s medium and the identification of fungal colonies using the VITEK®2 YST. At T1, 42 (70%) subjects, were free of Candida, while after 6 months of treatment, the number decreased to 25 (41.67%). Two types of fungi, C. albicans and C. parapsilosis, predominated in the test performed at T1. The study at T2 showed that C. albicans most frequently colonized the oral cavity in 23 children (38.33%). Three new strains C. dubliniensis, C. kefyr, and C. krusei were identified at T2. Statistical analysis showed a significant correlation between the culture results and the age of the patient at T2. Patients older than 9 years had significantly more positive tests. Orthodontic treatment with removable appliances contributes to increased oral colonization by Candida spp.

Full textAbstract:
Objective: To compare young people’s experiences of wearing a range of orthodontic appliances. Design: A cross-sectional, qualitative study with purposive sampling. Setting: UK dental teaching hospital. Participants: Twenty-six orthodontic patients aged 11–17 years. Methods: Patients participated in in-depth semi-structured interviews. All interviews were transcribed verbatim and analysed thematically. Results: Young people reported physical, practical and emotional impacts from their appliances. Despite these reported impacts, participants described ‘getting used’ to and, therefore, not being bothered by their appliance. Framework analysis of the data identified a multi-dimensional social process of managing everyday life with an appliance. This involves addressing the ‘dys-appearance’ of the body through physically adapting to an appliance. This process also includes psychological approaches, drawing on social networks, developing strategies and situating experiences in a longer-term context. Engaging in this process allowed young people to address the physical, practical and emotional impacts of their appliances. Conclusion: This qualitative research has identified how young people manage everyday life with an appliance. Understanding this process will help orthodontists to support their patients.

Full textAbstract:
Removable orthodontic appliances are known to be the cause of various complaints related to oral handling of food and beverages, phonation and vocalization. To evaluate the complaint regarding appliance and its effect on taste and flavor perception ,100 volunteers were selected for the study. Two groups (I and II) of 50 children each were divided as study and control groups between the age group of 8- 13 years. Selected volunteers were given taste and flavor stimuli and were asked to score as per their perception in different testing sessions. The overall results revealed that volunteers from both study and control groups, irrespective of the use of removable orthodontic appliances showed marked variation in the estimation of the taste and flavor stimuli in different testing sessions. However, the results obtained were statistically not significant.
