ABSTRACT Objective: To assess the prevalence of malocclusion and treatment need in children and adolescents with sickle cell disease (SCD). Materials and Methods: In this cross-sectional study, the sample size comprised 35 five-year-old children and 36 adolescents of both sexes, aged between 12 to 18 years, with SCD. Dental occlusion was assessed using two indexes: the Malocclusion Index (World Health Organization) and the Dental Aesthetic Index (DAI). Results: The prevalence of malocclusion in the preschool children was 62.9%. The main malocclusions observed in this age group were Class II (37.1%), increased overjet (28.6%), reduced overbite (28.6%), and open bite (17.1%). In the 12- to 18-year-old subjects, the prevalence of malocclusion was 100%, and the most prevalent types of malocclusion were maxillary overjet (63.9%) and maxillary misalignment (58.3%). It is noteworthy that the majority of adolescents (80.6%) had very severe or disabling malocclusions. Conclusion: The results revealed a high prevalence of malocclusion in children and adolescents with SCD. According to DAI score, the majority of the sample presented with very severe malocclusion and a compulsory treatment need.

AbstractIntroductionThe adequate indications for the timing of treatment for Class II malocclusion are mandatory for the ethical and efficient practice of orthodontics, but clinicians are reluctant to accept new information that contradicts their preferred method of treatment.ObjectiveThe aim of this investigation was to assess the agreement regarding the indications for Class II malocclusion interceptive therapy between a group of international opinion-makers on early treatment and a group of orthodontists and to compare their treatment indications with the current evidence-based knowledge.Material and methodAn electronic survey containing photographs of mild, moderate and severe Class II malocclusions in children was sent to two panels of experts. Panel 1 (n=28) was composed of international orthodontists who had authored world-class publications on early orthodontic treatment, and Panel 2 (n=261) was composed of clinical orthodontists. Based on a 5-point Likert-type scale, the orthodontists selected their therapy option for each of the 9 Class II malocclusion cases.ResultThe Class II malocclusion treatment recommendations of Panel 2 were significantly different from those offered by Panel 1 with a skew of at least 1 scale point toward earlier treatment. The Class II malocclusion treatment recommendations of the members of Panel 1 members were in accordance with contemporary evidence-based knowledge.ConclusionClass II malocclusion overtreatment appears to be the tendency among clinical orthodontists but not among orthodontists who are academically involved with early treatment. There is a gap between the scientific knowledge and the practices of orthodontists.

Introduction: Various forms of malocclusion are a matter of serious concern in Nepalese population. This study was carried out to understand the prevalence of malocclusion among the school children of Biratnagar. The objective of this research is to find out the prevalence of malocclusion of children from different schools of Biratnagar visiting the Pedodontics and Orthodontics department of Nobel Medical College and Teaching Hospital, Biratnagar. Materials and Method: A descriptive cross sectional study method was used in this research. Data was collected by using direct observation of the subjects and occlusal assessment was done according to Angle’s classification and Dewey’s modification types of class I, class II and class III malocclusion. Result: Subjects with normal occlusion was found to be 39 % and with malocclusion was found to be 61%. Among them, class I malocclusion (60%) and angles class II div I subjects (88.33%) were in majority of the total study population. Conclusion: The present study helps to determine the prevalence of malocclusion and need of orthodontic treatment for the school children of Biratnagar

ABSTRACT Objective: To assess the relationship between malocclusion severity and quality of life in children. Materials and Method: Two hundred and seventy-eight children aged 11 to 14 years were recruited voluntarily from the Dental and Maxillofacial Centre of the Almana General Hospital in Alkhobar, Saudi Arabia. The children were asked to fill out the Arabic version of the Child Perception Questionnaire for 11- to 14-year-old children (CPQ11–14) and were then clinically examined to determine the severity of their malocclusion using the Dental Aesthetic Index (DAI). Multivariate analysis of variance was used to compare the four domains and the total CPQ11–14 scores between the four DAI severity groups. Results: Significant differences were found between DAI severity groups for the four domains and the total CPQ11–14 scores. Although children with very severe (handicapping) malocclusion had significantly higher domain and total CPQ11–14 scores than all the other groups (differences of up to 6 and 22 units, respectively, compared to children with no/minor malocclusion), there were no differences between those with no/minor, definite, and severe malocclusion. Conclusion: These findings suggest that only very severe malocclusion had an impact on the quality of life of the participants. Orthodontists should focus not only on clinical measures of malocclusion but should also consider the impact of severe malocclusion on patients' quality of life.

Abstract Objective: To evaluate if prematurely born children have higher prevalence of malocclusion traits and greater orthodontic treatment need than matched full-term born controls. Materials and Methods: Seventy-three preterm children were selected from the Medical Birth Register and divided into two subgroups according to their gestational age. One group consisted of 37 very preterm children (VPT), born in gestational week 29–32, and the other of 36 extremely preterm children (EPT), born before the 29th gestational week. The subjects were compared with a control group of 41 full-term children, who were matched for sex, age, and nationality. Data from clinical examinations, study casts, and panoramic radiographs were used to determine malocclusion traits. The dental health component of the index of orthodontic treatment need (IOTN) was used to rank the treatment need. Results: Two or more malocclusion traits occurred significantly more often among EPT (83.3%) and VPT children (73.0%), compared with the full-term children (51.2%). Significantly higher prevalence of deep bites and was found in EPT and VPT groups compared with the full-term control group. Deep bite was the most common malocclusion trait in the EPT and VPT group. Higher orthodontic treatment need was found for the preterm children but no differences in prevalence of malocclusion traits and treatment need were found between VPT and EPT children. Conclusion: The clinician should be aware of the potential for a higher number of malocclusion traits and greater orthodontic treatment need in prematurely born children compared with full-term children.

Full textAbstract:
An epidemiological investigation involving 765 Glasgow schoolchildren aged nine, twelve, and fifteen years was undertaken to assess the severity of malocclusion, the need for Orthodontic treatment, and the proportion of children in each age group who had previously received treatment. An index termed the Malocclusion Severity Index (MSI) was developed to establish objectively the severity of malocclusion in each individual. Fifty sets of orthodontic study models and six Orthodontics assessed the reproducibility and validity of the index. Although there was a significant reduction in the proportion of children in need of Orthodontic treatment between 9 and 15 years of age, a considerable number were still in need of treatment; crowding of their dentitions being responsible for the majority of the treatment requirement. The MSI was found to be as precise and valid as previously developed occlusal indices, for estimating the treatment needs of sample populations.

Full textAbstract:
Interceptive orthodontics in mixed dentition period of children is practiced to prevent the severity of incurred malocclusion at an incipient juncture of life. Identifying malocclusion at a very early phase and diagnosing it at right age can help the pediatric dentists to achieve stability as far as the treatment is concerned. Mesiodens is a common type of supernumerary tooth which is found commonly in the incisor region of oral cavity. This anomalous occurrence can lead to varied complications like unerupted teeth, displaced teeth etc. This case report deciphers a case of mesiodens causing anterior teeth malocclusion and its management by 2 x 4 Orthodontic appliance.

Full textAbstract:
Sleep-disordered breathing (SDB) is often related to malocclusion, and dentists should be able to recognize occlusal changes that may be associated with the development, onset, or persistence of SDB. Although clinical examination is routinely used by specialists in orthodontics and functional jaw orthopedics, differences in diagnosis are very common. Method : Two observers, both dentists specializing in functional jaw orthopedics, examined 56 children aged 7 to 9 years. Intra- and interobserver agreement in identification of functional orthopedic and orthodontic conditions were assessed. Results : Intraobserver agreement was strong for all variables. Interobserver agreement was also strong, except for the variable overbite, which showed good agreement. Conclusion : Diagnostic criteria provide an opportunity for dentists to recognize dental malocclusions that may be associated with sleep-disordered breathing.

ABSTRACT Objective: To follow a group of children from primary to early permanent dentition and determine the prevalence, self-correction, and new development of malocclusions; the need for orthodontic treatment; and the possible influences of habits, breathing disturbances, and allergies. Materials and Methods: Two hundred and seventy-seven children were followed at 3, 7, and 11.5 years of age. Malocclusions and orthodontic treatment need were determined by clinical examinations. Data on sucking habits, breathing disturbances, allergies, dental trauma, and orthodontic treatments were collected from a questionnaire and dental records. Results: Malocclusions were found in 71% of participants at 3 years of age, 56% at 7 years of age, and 71% at 11.5 years of age. Self-correction was noted for anterior open bite, sagittal malocclusions, and posterior crossbite, while deep bite developed. A high number of contact point displacements and spacings contributed to the prevalence of malocclusion rate of 71% at 11.5 years. Severe or extreme orthodontic treatment need was apparent in 22%. Habits, allergies, or breathing disturbances found at 3 years of age had no associations with malocclusions at 11.5 years of age. Conclusions: This sample revealed a significant percentage of malocclusions and orthodontic treatment need. A substantial number of self-corrections and establishment of new malocclusions occurred during the transition from primary to early permanent dentition.

Introduction.Physical, mental, and social consequences of malocclusion may impact the quality of life. The aim of this review is to describe main factors motivating parents for orthodontic treatment for their children.Methods.A systematic review study design was used to identify articles analyzing different motivational factors in orthodontic treatment appearing in Medline database, EMBASE, and Google Scholar. The search terms used were teasing, motivating factors, orthodontics, malocclusion, quality of life, smile attractiveness, and perception of malocclusion. Papers selected up to May 2013 included retrospective and prospective longitudinal studies, randomized control trials, cross-sectional studies, reviews, and meta-analyses.Results.13 articles included in this review identified aesthetics as the main motivational factor in orthodontic treatment. Children mention teeth crowding, large overbite, missing teeth, and largest maxillary anterior irregularities also as motivational factors. Parents want their children to look nice and worry of being accused of neglecting parental duties.Conclusions.Dissatisfaction with one’s appearance, dentist recommendation, interest and worries of parents, and the impact of peers who wear braces rank among the main motivation factors of seeking orthodontic treatment. Understanding these factors allows better planning of resources and better assessment of the requirements and priorities of treatment.

Abstract Objective: To test the hypothesis that malocclusion and its impact on quality of life has no effect on 8- to 10-year-old Brazilian schoolchildren as measured by an oral health-related quality of life (OHRQoL) instrument. Materials and Methods: A cross-sectional study was carried out with a population-based sample of 1204 8- to 10-year-old children attending elementary schools in Belo Horizonte, Brazil. Dental examinations were carried out by two calibrated examiners. OHRQoL was assessed using the Brazilian version of the Child Perceptions Questionnaire. The Dental Aesthetic Index was used for the clinical assessment of malocclusion. Dental caries and socioeconomic factors were used as controlling variables. Bivariate analysis involved the chi-square test and the Fisher exact test. A Poisson regression model was employed for the multivariate analysis (P < .05). Results: Anterior segment spacing and anterior mandibular overjet were significantly associated with impact on OHRQoL (P < .05). Schoolchildren with malocclusion were 1.30-fold (95% CI: 1.15–1.46; P < 0.001) more likely to experience a negative impact on OHRQoL than those without malocclusion. Children belonging to families with an income less than or equal to two times the minimum wage were 1.59-fold (95% CI: 1.35–1.88; P < 0.001) more likely to experience a negative impact on OHRQoL than those belonging to families with the highest income. Conclusions: Schoolchildren with malocclusion from lower-income families experience a greater negative impact on OHRQoL.

Introduction:The practice of orthodontics is very young in South-South Nigeria and there is need for base line data for informed planning. This study was carried out to investigate the self-perception of malocclusion among Nigerian school children aged 12 to 18 years in order to compare their perception with that of an orthodontist and also to determine the influence of gender and age on self-perception.Materials and Methodology:A total of 612 randomly selected schoolchildren comprising 299 (48.9%) males and 313 (51.1%) females with a mean age of 15 + 2.0 years were included in the study, the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) was the instrument used to measure the perception of malocclusion by both the school children and the orthodontist.Results:Majority of the students (82.5%) rated their teeth towards the more attractive end of the scale (Grades 1-4). Although self - perception was not found to be related to gender, older children (16-18 years) had an increased level of perception of need. Males and older children were found to be more in need of treatment by the orthodontist.Conclusions:A significant difference was found between the orthodontist’s rating and the students’ ratings of the attractiveness of their occlusions. Age and gender were not found to influence self- perceived orthodontic treatment need. Therefore, for effective orthodontic care, self- perception and not only professional assessment must be taken into consideration when formulating treatment plans to ensure patient satisfaction.

ABSTRACT Objective: To evaluate the prevalence and severity of malocclusion in children suffering from β-thalassemia and to assess orthodontic treatment need using Grainger’s Treatment Priority Index (TPI) and index of orthodontic treatment need (IOTN)-dental health component (DHC). Methods: A cross-sectional study was conducted on 200 transfusion-dependent children diagnosed with homozygous β-thalassemia and 200 healthy school children aged 11-17 years. The TPI and IOTN-DHC data was recorded for both groups. Total TPI score for each subject was calculated and graded according to malocclusion severity estimate (MSE). Independent sample t-test was used to compare mean TPI scores, overjet and overbite between thalassemic and healthy children. Chi-square test was used to compare the frequency of IOTN-DHC grades, Angle’s classification, and MSE grades between thalassemic and healthy children. Results: The most prevalent malocclusion was Class I in normal children (67.5%) and Class II in thalassemic children (59%). The mean overjet and overbite were significantly (p<0.001) greater in thalassemic children than in healthy children. Severe tooth displacements were 3.5 times greater in thalassemic children, compared to controls. A greater proportion of thalassemic children were in IOTN grades 3 and 4, compared to the controls (p<0.001). MSE grades 4 and 5 were significantly (p<0.001) more prevalent in thalassemic children, compared to the controls. Conclusion: There is a high prevalence of Angle’s Class II malocclusion in thalassemic children. Majority of these children are categorized in higher grades of IOTN-DHC and TPI-MSE, showing a great severity of malocclusion and high orthodontic treatment needs.

Abstract Objective: To examine, in adolescents with mild to moderate malocclusion, the relationship between self-concept and demographic characteristics, a clinical assessment of malocclusion, self-perception of malocclusion, and self-perception of facial attractiveness. Methods and Materials: Fifty-nine consecutive patients ages 9 to 15 years scheduled for initial records in a graduate orthodontic clinic consented to participate. Each subject independently completed the Multidimensional Self-Concept Scale (MSCS), the Facial Image Scale, and the Index of Treatment Need–Aesthetic Component (IOTN-AC). Peer Assessment Rating (PAR) scores were obtained from the patients' diagnostic dental casts. Forward multiple-regression analysis with a backward overlook was used to analyze the effect of the demographic, clinical, and self-perception measures on each of the six self-concept (MSCS) domains. Results: Self-perception of the dentofacial region was the only statistically significant predictor (P < .05) for the Global, Competence, Affect, Academic, and Physical domains of self-concept, while age, parental marital status, and the adolescent's self-perception of the dentofacial region were statistically significant predictors (P < .05) of Social Self-Concept. Conclusion: The self-perceived level of the attractiveness or “positive” feelings toward the dentofacial region is more strongly related to self-concept than the severity of the malocclusion as indicated by the PAR score or by the adolescent's perception of their malocclusion.

ABSTRACT Objective: To test the hypothesis that malocclusion does not have an independent and negative effect on quality of life of adolescents. Materials and Methods: The cross-sectional design study comprised a sample of 519 children, aged 11 to 14 years, attending public schools in Osorio, a city in southern Brazil. One calibrated examiner carried out clinical examinations and recorded dental caries (decayed/missing/filled teeth), malocclusion (Dental Aesthetic Index), and dental trauma. Participants completed the Brazilian version of the Child Perceptions Questionnaire (CPQ11–14), Impact Short Form, and their parents or guardians answered questions about socioeconomic status. Simple and multivariate linear regressions were performed to assess covariates for the overall CPQ11–14 scores. Results: Greater impacts on oral health–related quality of life were observed for girls (P = .007), children with a lower household income (P = .016), those living in nonnuclear families (P < .001), and those with more decayed/missing/filled teeth (P = .001). Malocclusion was also associated with oral health–related quality of life: the severity of malocclusion was significantly related to higher scores of CPQ11–14 even after scores were adjusted for control variables. CPQ11–14 increased by approximately 1 point for each increase in the severity of malocclusion. Conclusions: Malocclusion has a negative effect on adolescents' quality of life, independent of dental caries or traumatic dental injuries. Socioeconomic inequalities and clinical conditions are important features in adolescents' quality of life.

ABSTRACT Objective: The aim of the present cross-sectional study was to assess the impact of malocclusion on the quality of life of children aged 8 to 10 years attending public elementary schools in Belo Horizonte, State of Minas Gerais, Brazil. Methods: The Brazilian version of the Child Perceptions Questionnaire 8-10 (CPQ8-10) was used to evaluate oral health-related quality of life. The children were examined for the diagnosis of malocclusion using the Dental Aesthetic Index (DAI). The data were analyzed by bivariate and multivariate descriptive statistics using Poisson regression at a 5% significance level. A total of 270 children participated in the study. Results: Children with normal occlusion or mild malocclusion (DAI ≤ 25) were 56% less likely (95%CI: 0.258-0.758; p= 0.003) to have their quality of life affected compared with children diagnosed with extremely severe malocclusion (DAI ≥ 36). Children with a maxillary anterior overjet ≥ 3 mm had higher CPQ8-10 mean scores (19.4; SD = 17.1) than those with an overjet < 3 mm (13.6; SD = 11.7; p= 0.038). Conclusions: Extremely severe malocclusion and pronounced maxillary anterior overjet were associated with a negative impact on quality of life.

Abstract Introduction. With advances in technology, there has been a need for more precise imaging methods which have become an integral part of the orthodontic treatment plan. Aim. The aim of this study is to present diagnostic methods that are currently used in children with malocclusion. Material and methods. The materials analysed in this review are articles from PubMed and Google Scholar. To identify relevant publications, the search was carried out using the key word combination: imaging, diagnostics, malocclusion, children, orthodontics. The number of 16 research papers in which these keywords appeared were qualified for this review. Results. According to the mentioned publications, pantomographic images are the most frequently recommended method for detecting dental anomalies. Cephalometry was used to observe changes in the facial axis and to measure the length of the jaw. CBCT is being used more and more often, mainly to identify possible prognostic factors in the case of canine retention/eruption in the maxilla. The method of magnetic resonance imaging was also compared with cephalometric images. Conclusions. 1. The pantomogram is a useful and frequently used method in the detection of craniofacial anomalies. 2. Cephalometry allows the effects of the treatment to be monitored. 3. CBCT is a significant diagnostic tool to assess the growth of craniofacial structures. 4. MRI diagnostics limits the patient’s exposure to harmful ionizing radiation. 5. There is a need to educate medical staff and conduct further research on the methods of diagnostic imaging in children.

Abstract Objective: To study the effects of cervical headgear treatment of Class II division 1 malocclusion on upper airway structures in children. Materials and Methods: Forty children aged 9.1 (7.2–11.5) years with Class II division 1 malocclusion were treated using a cervical headgear as the only treatment appliance. The headgear consisted of a long outer bow bent 15° upward and a large inner bow expanded 10 mm larger than the intermolar distance. Lateral cephalograms were taken before and after the treatment. Upper airway structures were estimated from the cephalograms. The results were compared to cross-sectional data of 80 age-matched controls with a Class I molar relationship. Results: A Class I molar relationship was achieved in all treated children. The mean treatment time was 1.6 (0.3–3.1) years. The Class II malocclusion was accompanied by a similar or wider nasopharyngeal space than in the controls but narrower oro- and hypopharyngeal spaces. The retropalatal area was widened by the treatment (P < .05), whereas the rest of the oropharynx and hypopharynx remained narrower than in the controls. Before the treatment, the mandibular plane was in a more horizontal position than in the controls, but during the treatment, it rotated to a position similar to that of the controls. Conclusion: Class II division 1 malocclusion is associated with a narrower upper airway structure even without retrognathia. Headgear treatment is associated with an increase in the retropalatal airway space.

ABSTRACT Objective: To evaluate the effectiveness of rapid maxillary expansion (RME) on the sagittal dental or skeletal parameters of growing children with Class II malocclusion. Materials and Methods: A systematic review intended to identify relevant literature was conducted. The search was performed on Medline, Embase, Cochrane Library, and Scopus databases. Reference lists of the included articles were also screened for relevant documents. The qualitative assessment was performed according to the Methodological Index for Non-Randomized Studies (MINORS) tool, and the resultant data were grouped and analyzed concerning dental and skeletal sagittal effects of RME. Results: Of 25 screened studies, seven articles met eligibility criteria and were included. Study samples were observed during mixed dentition stage and characterized as having either Class II dental malocclusion or skeletal discrepancy. None of the included studies was a randomized clinical trial. Included controlled studies presented several inadequacies related to control group or lacked appropriate comparative statistical analysis. Besides being frequently based on deficient methodology, dental and skeletal sagittal effects of RME were either controversial or lacked clinical relevance. Conclusion: The effect of RME on the sagittal dimension of Class II malocclusions has not been proved yet. Future randomized controlled clinical trials are still needed to definitely address this question.

Abstract Objective: To compare the cephalometric characteristics of children with Class III malocclusion to those of children with normal occlusion during the deciduous dentition phase. Materials and Methods: Cephalometric measurements of 27 children (mean age: 5.03 years) diagnosed with Class III malocclusion were compared with 32 children (mean age: 4.85 years) diagnosed with normal occlusion in the following four categories: sagittal skeletal analysis, vertical skeletal analysis, dentoalveolar analysis, and soft tissue analysis. Results: Significant differences were seen in all categories except vertical skeletal analysis. Sagittal skeletal measurements included ANB (Class III group: −0.91 ± 1.60; normal group: 5.28 ± 1.29), facial convexity (Class III group: 0.47 ± 4.32; normal group: 13.65 ± 3.44), Wits appraisal (Class III group: −5.54 ± 2.36; normal group: −0.84 ± 1.91), and A to N-perpendicular (Class III group: −2.94 ± 3.05; normal group: 0.78 ± 2.53). Dentoalveolar measurements included U1 to NA (Class III group: 11.98 ± 5.25; normal group: 8.12 ± 5.43), IMPA (Class III group: 81.34 ± 7.40; normal group: 86.57 ± 5.67), and interincisal angle (Class III group: 152.65 ± 8.82; normal group: 145.03 ± 7.34). Soft tissue measurements included soft tissue convexity (Class III group: 2.47 ± 4.20; normal group: 12.71 ± 3.95), nasofacial angle (Class III group: 22.68 ± 4.22; normal group: 26.24 ± 3.84), and upper lip to esthetic plane (Class III group: −0.65 ± 2.74; normal group: 3.07 ± 1.90). Conclusions: There are significant differences between the craniofacial patterns of normal children and those of children with Class III malocclusion that can be identified with cephalometric analysis as early as the deciduous dentition phase.

Aims This study aims to find the prevalence of orthodontic treatment need and malocclusion problems in 8–9-year-old schoolchildren in the south of Thailand. Materials and Methods A number of 202 children (100 boys and 102 girls) samples were randomly selected from all schools in Hat Yai District, Songkhla Province, Thailand. A cross-sectional survey of dental health component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and malocclusion problems was investigated by clinical examination and dental model. Results Levels 4 and 5 of orthodontic treatment need according to DHC of IOTN of the sample were presented in 18.8% and 1.49%, respectively. Children who need orthodontic treatment (Grade 2–4) showed more than one highest DHC problem that indicated the level of treatment need (39.68%). Normal occlusion was found at 6.43%. Malocclusions such as Class I, Class II division 1, Class II division 2, and Class III malocclusion were observed in 78.71%, 7.92%, 3.47%, and 3.47%, respectively. Reversed overjet and overjet >9 mm were detected in 5.64% and 1.58%, respectively. Approximately half of the children (46.67%) had overbite >3.5 mm. Conclusions High percentage of children in mixed dentition period who need orthodontic treatment was found in this study. Some children who presented with the orthodontic treatment need Grade 2–4 had more than one DHC problem which identified the grade of treatment need. Class I malocclusion was most frequently found in this group of children.

Relevance. Skeletal malocclusion stands at the head of all oral diseases and is encountered in 32-35% of children and adolescents in Russia [7;12;15]. The number of malocclusions has increase due to various reasons, one of which is early extraction of deciduous carious teeth resulting in impaired vertical dimension and occlusion of teeth [1;14]. Diagnosis with due regard to caries resistance degree and planning of respective operative and orthodontic treatment are indispensable in children with skeletal malocclusion. Purpose – to increase effectiveness of functional treatment of malocclusion in children with various degree of caries resistance.Materials and methods. There were examined 108 patients aged between 6 and 16 with Class I malocclusion according to Angle, abnormal arch-to-arch relationship and tooth position and various degree of caries resistance. 4 groups were formed: high, sufficient mean, decreased mean and low caries resistance of dental enamel. Intensity of carious process was detected in all patients before and after orthodontic treatment. The effectiveness of reminerlization administered by removable orthodontic appliances was evaluated by electrometrical testing of hard dental tissue. Surface EMG was used to assess normalization of tone of maxillofacial muscles in children by average amplitude of biopotentials of superficial masseter and temporalis muscles.Results. Сhanges in caries intensity in children after treatment with removable orthodontic aligners indicate the necessity for remineralization of hard dental tissues during orthodontic treatment and it is confirmed by decrease of electroconductivity of enamel in children with sufficient mean, decreased mean and low degree of dental enamel caries resistance. Increase of biopotential mean amplitude during «total mastication» for masseter and temporal muscles confirms effectiveness of preformed elastic positioner along with myodynamic exercises.Conclusions. The conducted study proves the necessity of comprehensive approach with procedures increasing the degree of caries resistance of hard dental tissues during orthodontic treatment of skeletal malocclusion in children.

ABSTRACT Introduction The present study analyzed the characteristics of malocclusions, occlusal traits among Special Health care Needs (SHCN) children with Down syndrome (DS) and autism disorder (AD) in Riyadh City, Kingdom of Saudi Arabia. Materials and methods A total of 100 DS and 100 AD children from five rehabilitation centers in and around Riyadh, Kingdom of Saudi Arabia, were included in the study. Any children with history of ongoing medical treatment, extraction, or orthodontic treatment were excluded from the study. Out of the 200 patients examined, 131 were males and 69 were females and the age of the children ranged from 6 to 14 years. The children were examined for malocclusion characteristics using the Angle's classification of malocclusion, and also other occlusal traits, such as overjet, overbite, cross bite, and open bite were also determined. The data obtained were analyzed using Statistical Package for the Social Sciences, version 16 to generate descriptive statistics for each variable. Results The analyzed data of the right and left permanent molar relation showed higher incidence of class III malocclusion (66%) in DS children as compared with (3–4%) AD children. The AD children presented with higher percentage of class I malocclusion (40–41%) as compared with (10–14%) DS children. During examination of the primary molars, the analyzed data showed that left primary molar had more mesial shift in AD children as compared with DS children. Conclusion Down syndrome children had high incidence of class III malocclusion and autistic children had high incidence of class I malocclusion. Overall, the DS children were more prone to malocclusion. Clinical significance This study provides database for health professionals in Saudi Arabia in regard to malocclusion of autistics and DS patients. How to cite this article Alkhadra T.

ABSTRACTObjective: To determine the effects of occlusion on maximum bite force of growing subjects.Materials and Methods: Incisor and first molar bite force of children and adolescents was evaluated. Four cohorts were measured annually for 3 years, starting at approximately 7, 9, 12, and 15 years of age, respectively. The initial sample included 182 females and 198 males; there were 130 subjects with normal occlusion, 111 with Class I malocclusion, and 139 with Class II malocclusion. Multilevel analyses were performed to model the growth changes and compare groups.Results: Maximum bite force increased significantly (P < .05) over time. Incisal forces peaked at 14.3 and 15.3 years of age for females and males, respectively. Maximum molar bite force peaked at 16 years for both males and females. Subjects with normal occlusion had significantly higher bite force than subjects with malocclusion. Maximum molar bite force exhibited a significant testing effect, with forces increasing 2.6 kg each year that the tests were repeated.Conclusions: Malocclusion has a detrimental effect on bite force. Changes in maximum bite force are also due to age, sex, and repeated testing.

Worldwide, with the economic growth malocclusions recorded a significant increase, which has led to their ranking as the third most widespread oral health problem after dental caries and periodontal disease being considered the third priority among oral problems by the World Health Organization. The aim of this study consisted of an evaluation of the socio-environmental factors associated with dental malocclusion. The clinical characteristics of 125 children (from 5 to 12 years old, with no previous orthodontic treatment), were evaluated by means of a visual examination . Information about the socio - environmental characteristics of the children�s families were collected by means of a questionnaire addressed to their parents/guardian. The prevalence of malocclusions was 67.5% (84). Regarding the types of malocclusions included in this study and the most prevalent were: increased overjet 33.33% (28), deep overbite 21.42% (18), posterior crossbite 9.52% (8) and anterior open bite 2.38% (2). The results underline the need to reduce social disparities in oral health among children. In conclusion, it was observed that the socio-environmental factors influence the curative dental needs of children. Some associations were found between malocclusion and societal/behavioral parameters.

Summary Background/objectives Whether orthodontic treatment with functional appliances improves facial aesthetics is still under debate. This study aimed to determine whether functional orthodontic treatment improves the facial attractiveness of patients with Class II division 1 malocclusion. Materials/method Extraoral lateral photographs of 20 children with Class I (CLI, 11.7 ± 0.8 years), and before (T1) and after treatment (T2) photographs of patients with Class II division 1 (CLII T1 and CLII T2; mean age ± SD = 11.1 ± 0.6 years) treated with functional appliances, were transformed into black silhouettes. Three panels of examiners including 30 orthodontists (39.0 ± 10.1 years), 30 dentists (40.0 ± 9.7) and 30 laypersons (39.0 ± 9.2) evaluated the attractiveness of patients’ silhouettes using a 100-mm visual analogue scale, and the sagittal position of patients’ upper lip, lower lip, and chin using a 3-point Likert scale. Two-way ANOVA and a chi-square test were used to test differences among groups. Statistically significance was set as P < 0.05. Results The silhouettes of CLII T2 individuals were more attractive than those of the other groups (all Ps < 0.001). The upper lip, lower lip, and the chin of these individuals were judged to be normally positioned in 69.5 per cent, 74.9 per cent, and 72.3 per cent of the assessments, respectively (all Ps < 0.05). Limitations This study did not account for the psychological profile of the examiners, which may have affected the ratings. Conclusions/implications Orthodontic treatment with functional appliances is associated with a superior facial profile attractiveness. Functional treatment should be considered as a treatment option to improve the facial appearance of children with Class II division 1 malocclusion.

OBJECTIVE: To determine the normative orthodontic treatment need among 12-year-old Brazilian schoolchildren, in the municipality of Juiz de Fora, Minas Gerais, Brazil, and compare with the need as perceived by the children themselves and their parents or caregivers, assessing putative associated sociodemographic factors. METHODS: Four hundred and fifty one children without a previous history of orthodontic treatment were randomly selected from a population of 7,993 schoolchildren regularly attending the public and private educational sectors of the municipality of Juiz de Fora, Minas Gerais, Brazil. RESULTS: The prevalence of normative orthodontic treatment need in 12-year-old children, assessed with the Dental Aesthetic Index (DAI) was 65.6% (n = 155). The need perceived by the caregivers was 85.6%, and by the children was 83.8%. Only the perception by the caregivers maintained a significant correlation with the normative need of treatment when adjusted to the parents' schooling and economical level (p = 0.023). CONCLUSIONS: There is a high prevalence (65.6%) of malocclusion requiring orthodontic treatment in 12-year-old Brazilian schoolchildren. The most prevalent malocclusions in the study were: Crowding, Class II molar relationship and increased overjet. There was no significant correlation between the Index of Orthodontic Treatment Need - Aesthetic Component (IOTN-AC) related to dental aesthetic perception and the normative treatment need assessed with the DAI.

Abstract Objective: To examine the effects of face mask therapy in adolescent and young adult female subjects with skeletal Class III malocclusion characterized by maxillary retrognathism. Materials and Methods: The material consisted of pretreatment and posttreatment lateral cephalometric radiographs of 28 subjects with Class III malocclusions treated with a face mask. Twenty-eight patients age 10 to 16 years were divided into two groups: the adolescent group (15 female patients) and the young adult group (13 female patients). Within group and between group comparisons were made by paired t-test and Student's t-test, respectively. Results: Forward displacement of the maxilla and clockwise rotation of the mandible occurred in both the adolescent and young adult groups. Maxillary-mandibular relationship exhibited an increase in the ANB angle and Wits appraisal, and the soft-tissue changes resulted in a more convex profile. The maxillary incisors moved forward while the mandibular incisors moved backward. Conclusions: Face mask therapy improves skeletal Class III malocclusions by a combination of skeletal and dental changes. Although early treatment may be most effective, face mask treatment can provide a viable option for older children as well.

ABSTRACT Objectives To determine factors that could predict Class II/1 malocclusion patient compliance during functional treatment. Materials and Methods The sample consisted of 77 subjects (aged 11–13 years; 47% girls) presenting with Class II/1 malocclusion. Inclusion criteria were distal molar relationship, overjet greater than 5 mm, and confirmed pubertal growth spurt. Removable functional appliances (62% Twin Block [TB], 38% Sander Bite Jumping [BJ]) with built-in maxillary expansion screws were used. Follow-up period was 1 year. Patients and parents independently filled out the Child Perception Questionnaire, Parental/Caregiver Perception Questionnaire, and Family Impact Scale to assess emotional and social well-being, oral symptoms, functional limitations, parental emotions, family activities, conflicts, and financial burden as possible predictors of compliance during treatment. Sex, overjet, and appliance type were also analyzed. Results There were more noncompliant than compliant patients (55% vs 45%). Parental perception of altered emotional well-being of their children was the strongest predictor, increasing compliance odds 3.4 times (95% confidence interval [CI], 1.2–9.4; P = .017). Patients were 3.2 times (95% CI, 1.1–9.3; P = .033) more likely to cooperate with TB compared with BJ appliance. OJ ≥ 8 mm increased compliance odds 3.1 times (95% CI, 1.0–9.4; P = .044). Conclusions Parental perception of child's emotional well-being alteration, severity of malocclusion, and type of appliance are major predictors of compliance. Psychosocial issues and oral function limitations reported by children and family impact are of negligible influence.

Introduction/Objective. Class III malocclusion is a sagittal intermaxillary disproportion with dominant presence of mandible. Apart from primary sagittal, anomalies in vertical face dimension can also be present. The aim of this study is to evaluate vertical facial disproportions in the skeletal Class III malocclusion in stage of mixed dentition, in order to better plan its early therapy. Methods. In total 100 children were randomly selected and divided according to cephalometric analyzes in the two equal groups: Group 1 (experimental group) ? skeletal Class III malocclusion (n = 50) and Group 2 (control group) ? skeletal Class I (n = 50). The groups were further divided into three subgroups according to the age and gender of the children. Vertical craniofacial proportions were measured by anterior (upper, lower and total) and posterior facial height and their proportion. The values were statistically analyzed (p ? 0.05). Results. Upper anterior, lower anterior, total anterior and posterior facial height, proportion between lower and total anterior facial height, and proportion of posterior to total anterior facial height did not have a significant difference among children with Class I and Class III malocclusions. Upper anterior facial height proportional to total anterior facial height was statistically significant greater in experimental group when compared to control. Significant gender dimorphism was noted among the same subgroups. Conclusion. Vertical craniofacial proportions in children with Class III malocclusion in stage of mixed dentition was not significantly changed. This finding leaves room for the successful application of early, individually planned orthodontic therapy.

ABSTRACT Objective: To compare Phase 1 treatment, using the Frankel 2 (FR2) or the modified Twin Block (MTB), for Class II division 1 malocclusion in children and adolescents with respect to: treatment duration, number of appliance breakages, occlusal outcome, and patient and parent perspectives. Materials and Methods: Sixty participants with a Class II division 1 malocclusion were randomly assigned to either the FR2 or MTB appliance in a two-armed parallel randomized clinical trial with an allocation ratio of 1 to 1. Time to achieve a Class I incisor relationship was the primary outcome. The number of appliance breakages was recorded. The Peer Assessment Rating (PAR) index was used to evaluate pre- and post-treatment occlusal outcome on study models. Participants completed the child OHRQoL (oral health-related quality of life), Piers-Harris, Standard Continuum of Aesthetic Need (SCAN), and Oral Aesthetic Subjective Impact Score (OASIS) questionnaires pre- and post-treatment; parents completed a SCAN questionnaire. Results: Forty-two participants completed treatment (FR2: 20; MTB: 22). Multiple imputation was used to impute missing data for noncompleters. Mean treatment duration was similar for the two appliances (FR2: 376 days [SD 101]; MTB: 340 days [SD 102]; P = .41). There were no significant differences in mean number of appliance breakages (FR2: 0.3 SD 0.7; MTB: 0.4 SD 0.8; P = .67 or mean PAR score P = .48). Patient and parent perspectives did not differ between appliances (P > .05). Conclusions: Phase 1 treatment duration, number of appliance breakages, occlusal outcome, and patient and parent perspectives were similar in 11–14 year olds with Class II division 1 malocclusion treated using the FR2 or MTB appliance.

ABSTRACT Objectives: To analyze differences in upper cervical spine and craniofacial morphology, including posterior cranial fossa and growth prediction signs, between Danish and South Korean pre-orthodontic skeletal Class II children and to analyze associations between upper cervical spine morphology and craniofacial characteristics. Materials and Methods: One hundred forty-six skeletal Class II children—93 Danes (54 boys and 39 girls, mean age 12.2 years) and 53 Koreans (27 boys and 26 girls, mean age 10.8 years)—were included. Upper spine morphology, Atlas dimensions, and craniofacial morphology, including posterior cranial fossa and growth prediction signs, were assessed on lateral cephalograms. Differences and associations were analyzed by multiple linear and logistic regression analyses adjusted for age and gender. Results: Significant differences between the ethnic groups were found in the sagittal and vertical craniofacial dimensions (P < .001), mandibular shape (P < .01), dental relationship (P < .01), posterior cranial fossa (P < .05), and growth prediction signs (P < .001). No significant differences were found in upper spine morphology and Atlas dimensions between the groups. Upper spine morphology/dimensions were significantly associated with the cranial base angle (P < .01), sagittal craniofacial dimensions (P < .001), posterior cranial fossa (P < .001), and growth prediction signs (P < .05). Conclusions: Upper spine morphology/dimensions may be valuable as predictive factors in treatment planning for growing Class II children.

Aim: To evaluate the prevalence of anterior crossbite and to verify the effectiveness of the orthodontic appliance Inclined Plane in the correction of this malocclusion. Methods: The clinical examination was performed 702 children in the deciduous or mixed dentition of 7 schools and in those found the anterior crossbite was performed treatment with fixed Inclined Plane. Results: The prevalence of the anterior crossbite was 2.14%, characterizing 15 of the 702 children evaluated, of which 60% were female and 40% male, all of which were dental crossbites. Only 12 accepted the treatment with an average duration of 4.4 weeks. Conclusion: The prevalence of anterior crossbite was 2.14%. The inclined plane proved to be a viable and effective therapy in the correction of anterior crossbite. It is one of the options of the orthodontic treatment in patients in the deciduous or mixed dentition, propitiating greater possibility of dentoskeletal development, since the malocclusion is corrected. However this method needs to be correctly indicated and its execution technique rigorously followed.

Background. Widespread use of the IOTN along with detailed study of occlusal traits is suitable for planning community dental health resources. Objectives. The aim of current study was to assess the need for orthodontic treatment among school children of Tehran by means of the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and also to evaluate the occlusal traits of the subjects. Methods. 684 (343 boys and 341 girls) school children, 15 to 17 years of age, were selected at random from 12 schools to represent the four main areas of Tehran. The final sample who met the inclusion criteria comprised 643 subjects (322 males and 321 females). Malocclusion was determined with the Index of Orthodontic Treatment Need. The IOTN grades were statistically compared in the two genders using chi-square test. Results. Orthodontic treatment need, using the DHC, was found in only 9.0 per cent of the children. The prevalence of Angle Class I malocclusion in this study was higher than other malocclusions (65.2 per cent), followed by crowding in 62.7 per cent of the subjects. Conclusion. Orthodontic treatment need for Tehran high school students was relatively lower than that reported in most recent studies in Europe.

The purpose of this study was to calculate uncertainty of orthodontic measurement in skeletal class III malocclusion children using lateral cephalometry analysis software which obtained traceability in previous study. Using this data, standard reference of measurement value for skeletal class III malocclusion was obtained.<br/>Lateral cephalometric data was collected from 144 children who visited Pediatric Dentistry from 2017 to 2020 for orthodontic treatment. Orthodontic measurement was analyzed with software which obtained traceability. Type A evaluation of uncertainty and type B evaluation of uncertainty was calculated to obtain combined standard uncertainty and expanded uncertainty. Standard reference of skeletal class III children was compared to standard reference of skeletal class I children.<br/>Distribution range for skeletal class III malocclusion children aged 6 to 10 with 95% confidence interval was provided using calculated uncertainty of orthodontic measurement value.
