AbstractDentists and oral and maxillofacial radiologists have used periapical, occlusal, panoramic, and cephalometric radiographs for many years for diagnosing dental anomalies, especially before orthodontic or surgical treatment. Cone beam computed tomography was developed in recent years especially for the dental and maxillofacial region. Thus it has become the imaging modality of choice for many clinical situations, such as the assessment of dental impaction and structural teeth anomalies or other associated diseases and disorders (e.g., Gardner's syndrome, cleidocranial dysplasia). This article reviews different aspects of dental impaction and its possible effects on adjacent structures such as external root resorption, marginal bone loss, as well as describing structural dental anomalies. It provides a systematic analysis of their characteristic features and imaging findings for general radiologists to achieve a precise diagnosis and an optimal interpretation.

Islamic teachings explain comprehensively how to purify, clean the body and the environment from uncleanness, and to use water and other washing media in a measured manner. In the concept of Islamic theory, this purification activity is known as thahârah. Due to the wide transmission of the Corona Virus Disease 2019 or Covid-19 throughout the world, this article offered preventive measures to restrain the spread of Covid-19 by practicing thahârah consistently based on a fiqh perspective. This study employed literary research method which traced a number of books by Islamic scholars related to the thahârah or purification procedures. After the data was collected, the analysis was carried out by analyzing, processing, and interpreting the data into a conclusion. The results revealed that in addition to eliminating hadaṡ, dirt, and impurity, thahârah activities such as wudhu, tayamum, titual bathing, and teeth brushing benefit for physical and spiritual health. If thahârah is practiced consistently; as a cleaning up routine activity, it will diminish the spread of Covid-19. Instead of just washing hands, for instance, it is recommended to do wudhu even if it is not for praying. Viruses sticking to the hands and face will be washed away and disappear if a person performs wudhu properly according to the teachings of the Prophet Muhammad. The research has shown that wudhu contains tremendous benefits for health as it can stimulate energy in the body and improve blood circulation.Ajaran Islam secara rinci menjelaskan bagaimana bersuci, membersihkan badan dan lingkungan dari najis, dan bagaimana menggunakan air dan media pencuci lainnya dengan terukur. Aktivitas bersuci tersebut dalam konsep Islam disebut thahârah. Sehubungan dengan telah menyebarnya virus corona 2019 atau Covid-19 yang melanda ke seluruh dunia, artikel ini menawarkan upaya tindakan preventif pencegahan tertularnya Covid-19 dengan membudayakan thahârah secara konsisten berdasarkan perspektif fikih. Penelitian ini menggunakan metode literary research, yakni menelusuri sejumlah buku-buku karya ulama Islam yang berhubungan dengan ṭahârah atau tatacara bersuci menurut fikih Islam. Setelah data terkumpul, dilakukan analisis dengan mengkalisifikasi, mengolah, dan menginterpretasi data menjadi suatu kesimpulan. Dari hasil analisis tersebut dapat disimpulkan bahwa selain bertujuan menghilangkan hadas, kotoran, dan najis, kegiatan thahârah seperti wudhu, tayamum, mandi, dan bersiwak bermanfaat untuk kesehatan jasmani dan rohani. Jika aktivitas thahârah ini dibudayakan secara konsisten, dalam arti dijadikan aktivitas yang rutin dalam membersihkan sesuatu, penyebaran Covid-19 akan tertekan menjadi minimal. Daripada mencuci tangan saja, misalnya, lebih baik sekalian berwudhu walaupun tidak untuk melakukan salat. Virus yang menempel di tangan dan wajah akan terbasuh dan lenyap jika seseorang melakukan wudhu dengan benar sesuai dengan ajaran Nabi Muhammad Saw. Penelitian membuktikan bahwa wudhu mengandung manfaat yang besar bagi kesehatan karena mampu merangsang dan menstimulus energi dalam tubuh serta melancarkan peredaran darah.

Abstract Introduction: A 200% increase in population growth among those over 85 is projected in the United States by 2050. Approximately half of women over 50 will experience an osteoporotic fracture in their lifetime. Osteoporosis disproportionately affects old-old adults (those between 85 and 95) as more than half of those admitted to the hospital for hip fracture are over 80 years of age. Older adults are also likely to need dental care. The American Dental Association guidelines offer preventive recommendations for those over 60 years of age but do not address the nuances of treatment options for nonagenarian persons. This case illustrates the treatment dilemma of nonagenarians wishing to optimize both bone and dental health. Case: We have a 95-year-old performance artist, who seeks to optimize bone health in the face of recommended dental work. She has been physically active her whole life and consumes adequate quantities of calcium and Vitamin D. She doesn’t smoke but has needed periodic glucocorticoids for exacerbations of chronic lung disease. At age 84 she began ibandronate but stopped due to worsening of esophageal reflux. She was then treated with teriparatide for 2 years. DEXA scans have shown declining hip T scores from -2.8 at age 88 to -3.5 at age 94 (osteoporotic bone density: T-score lower than -2.5). Her dentist recommended the extraction of several teeth before beginning zoledronate. She refused tooth extraction and sought treatment options to enhance her bone density. Discussion: Persons of advanced age are likely to have oral health problems requiring dental treatment. Bone health treatments such as bisphosphonates and denosumab are generally safe but can potentially cause osteonecrosis of the jaw even with simple tooth extraction in old-old population. Specific guidelines are lacking for treatment to maintain bone and dental health. The American Association of Oral and Maxillofacial Surgeons suggests that extractions and implants can be conducted as usual in patients who have been treated with oral bisphosphonates for less than four years and lack other clinical risk factors. A delay of two months is suggested for those who have been treated for more than four years or has taken glucocorticoids concomitantly. The approach is uncertain for old-old adults who are taking treatment but develop a need for dental surgery. More research is needed about options for optimizing dental health while enhancing bone density in aging population.

Dental medicine represents a very important part of our life. As our appearance or looks is a major concern for us, a beautiful smile can improve our life. Moreover, our teeth health reflects on our overall health. This paper presents a method for highlighting the differences between a natural tooth and a prosthetic one. In order to determine the stress distribution in teeth during the use of prosthetics pivots, several virtual geometric models of the teeth were created (canine, first premolar, first molar and second molar), both in their natural form and when using pivots. The results obtained from these analyses were compared in order to reveal the behavior of a prosthetic tooth during normal life loads. Such results of real life behavior can be used by dental medics in order to predict the life span of restored teeth.

Full textAbstract:
A 44-year-old male was referred to the Department of Orthodontics at Manchester Dental Hospital. He presented with pain from his heavily restored, lower right second premolar, which had an apical supplemental tooth, visible radiographically. The dentist queried whether the second premolar tooth could be extracted and the supplemental tooth aligned in its place. Clinical examination revealed no relevant abnormalities. The family and medical history were non-contributory. Panoramic tomography revealed multiple supplemental supernumerary teeth in the canine and premolar regions. Cone beam computed tomography and multidisciplinary team input were required to plan the treatment for this unusual case. CPD/Clinical Relevance: These findings highlight the management and treatment options for a case of non-syndromic, multiple supernumerary teeth. Consideration must be given to the risk of damage to adjacent structures if surgically removing supernumerary teeth, and the risk that supernumerary teeth may be ankylosed and not amenable to alignment within the arch.

Full textAbstract:
The implantation of cultured dental cell-cell re-associations allows for the reproduction of fully formed teeth, crown morphogenesis, epithelial histogenesis, mineralized dentin and enamel deposition, and root-periodontium development. Since vascularization is critical for organogenesis and tissue engineering, this work aimed to study: (a) blood vessel formation during tooth development, (b) the fate of blood vessels in cultured teeth and re-associations, and (c) vascularization after in vivo implantation. Ex vivo, blood vessels developed in the dental mesenchyme from the cap to bell stages and in the enamel organ, shortly before ameloblast differentiation. In cultured teeth and re-associations, blood-vessel-like structures remained in the peridental mesenchyme, but never developed into dental tissues. After implantation, both teeth and re-associations became revascularized, although later in the case of the re-associations. In implanted re-associations, newly formed blood vessels originated from the host, allowing for their survival, and affording conditions organ growth, mineralization, and enamel secretion.

Full textAbstract:
The aim of this study was to characterize dental anomalies. The pretreatment records (photographs and radiographs) of 2897 patients (41.4% males and 58.6% females) were utilized to detect dental anomalies. The dental anomalies studied were related to number, size and shape, position, and eruption. A Chi-square test was carried out to detect associations between dental anomalies, jaw, and sex. A total of 1041 (36%) of the subjects manifested at least one dental anomaly. The prevalence of all dental anomalies was jaw-dependent and greater in the maxilla, except for submerged and transmigrated teeth. The most frequently missing teeth were the maxillary lateral incisor (62.3%) and the mandibular second premolars (60.6%). The most frequent supernumerary teeth were the incisors in the maxilla (97%) and the first premolars in the mandible (43%). Dental anomalies are more frequent in the maxilla and mainly involve the anterior teeth; in the mandible, however, it is the posterior teeth. These differences can be attributed to the evolutionary history of the jaws and their diverse development patterns.

Objectives: This study aims to assess the self-perception of female dental students of their dental aesthetics regarding their satisfaction, its effect on their quality of life and felt need for treatment. Materials and Method: This is a descriptive study for 1st, 2nd and 3rd year dental students (n=110) in the College of Dentistry at Princess Nourah University (PNU). The survey was distributed via link "Google form". A 20 item questionnaire was prepared and tested before on seven students for clarity. Questions were regarding how students feel about their dental aesthetics and what they desire for treatment. Whether they felt their teeth affected their attractiveness, confidence and quality of life. Data was entered in SPSS for statistical analysis. Results: With a response rate of 94.5% majority (89.4%) of students felt their teeth affected the attractiveness of their faces. Almost one third (30.8%) have tried to hide their smile. Around half (51%) were not satisfied with their tooth colour. Almost two thirds of students (61.5%) felt their quality of life is affected by the appearance of their teeth. ‘Tooth whitening’ was selected by almost two thirds of students (64.4%) followed by almost half (46.2%) the students wanting ‘orthodontic treatment’. Conclusion: Dental aesthetics is rated highly among female dental students.The majority of the students felt that their teeth affected the attractiveness of their face and influenced their quality of life. Students desired teeth whiteneing followed by orthodontic treatment as their perceived need for aesthetic dental treatments.

Introduction: Age estimation can be based on tooth formation stages seen on the radiographs. Demirjian’s method is widely used to assess age of individuals with developing dentition. There are not many documented studies of age estimation amongst Nepali population.Objective: To assess the applicability of Demirjian’s method for dental age estimation in Nepali children.Materials & Method: The sample of the study consisted of 186 subjects between 7-16 years of age. Dental age estimation was based on Demirjian’s method and scored by a single observer.Result: The mean and mean differences in chronological and dental ages were calculated, which revealed the overestimation in age groups of 7 and 9 years, whereas there were underestimations in other age groups. The mean differences in age groups 12-16 were highly significant (p-Value <0.05) whereas the mean difference in age groups 7-11 years were not statistically significant.Conclusion: Since there is underestimation range from 0.5 years to 1.23 years, the standards of dental maturity described by Demirjian may not be suitable for Nepali children.

Abstract Objective: To examine pulpal vitality in teeth suffering dental trauma during orthodontic therapy with fixed appliances. Materials and Methods: Pulpal condition was evaluated in 59 teeth that had suffered dental trauma during orthodontic treatment (TO-group), in 800 orthodontically treated teeth without previous dental trauma (O-group), and in 193 orthodontically untreated teeth with previous dental trauma (T-group). Pulpal vitality was examined clinically and with radiographs. Degree of pulp obliteration was rated as absent, partial, or total. All teeth in the TO-group showed a positive sensibility test prior to resumption of orthodontic therapy. Results: Teeth in the TO-group revealed a significantly higher frequency of pulp necrosis than teeth in the O-group or teeth in the T-group (P &lt; .001, respectively). In the TO-group, teeth with extrusive or lateral luxation (P = .031) and teeth with intrusive luxation (P = .015) injuries showed a significantly higher rate of pulp necrosis than teeth with fracture of enamel. In addition, teeth with total pulp obliteration showed a significantly higher frequency of pulp necrosis than teeth without pulp obliteration (P = .013). Conclusion: Teeth with severe periodontal injury during orthodontic therapy and subsequent total pulp obliteration have an increased risk of pulp necrosis during additional orthodontic treatment stages.

ABSTRACT Aim The aim of this study was to evaluate the factors influencing the satisfaction of dental appearance and attitude toward treatments to improve dental esthetics among patients attending a dental teaching center. Methods A questionnaire was used to collect data of four background variables among 450 patients attended a dental teaching center in the city of Irbid in Jordan. The questionnaire enclosed self-reported questions about the appearance of anterior teeth, received esthetic treatment and desired treatment for improving esthetics. Descriptive, multiple logistic regression and Chi-square tests were used for data analysis (p ≤0.05). Results The 450 participants consisted of (66.2%) male and (33.8%) female. Of these, 69.3% were satisfied with their dental appearance and 58.0% with the color of their teeth. Esthetic restorations were the most received treatment (39.8%) and whitening of teeth was the most desired treatment (55.3%). The patients’ satisfaction with dental appearance was influenced by teeth color, crowding and receiving whitening (p < 0.05. r = 0.561, r2 = 0.315). The most desired esthetic treatments influenced by the satisfaction with dental appearance were esthetic restorations and orthodontics (p < 0.05. r = 0.223, r2 = 0.05). Significantly more female reported having esthetic restorations and orthodontics (p = 0.008, 0.000) and desired to have orthodontic, crowns or veneers and esthetic restorations (p = 0.000, 0.015, 0.028). Conclusion Satisfaction with dental appearance was affected by teeth color, feeling teeth are crowded, desire for esthetic restorations and orthodontic treatment. A high percentage of patients were not satisfied with the color of their teeth. Clinical Significance Recognizing the factors that affect patients’ satisfaction with their present dental appearance and attitude toward treatments to improve dental esthetic can guide clinicians to strategies to improve esthetics.

Abstract Objectives To identify relationships between masticatory ability and age, and dental and prosthodontic status amongst an institutionalized elderly dentate population in China. Materials and methods A sample of 512 elders living in eight nursing homes in Qingdao was categorized based on a hierarchical dental functional classification system with and without tooth replacements. Masticatory disability scores (MDSs) were analyzed using multiple regression models with only age, and age and dentition variables for participants having ≥ 10 natural and those having < 10 natural teeth in each jaw. Results Overall, associations between MDS and age, number of teeth, and number of teeth replaced by dental prostheses were identified. For participants having ≥ 10 natural teeth in each jaw, no significant associations between MDS and age and dental and prosthodontic status were found. Participants having < 10 natural teeth in each jaw had higher MDS (increasing chewing difficulties) at higher ages. However, when “premolar region sufficient” and “molar region sufficient” were included, MDS was not associated with age, but with these dentition variables. For participants having ≥ 10 teeth including prosthodontically replaced teeth in each jaw, age was the only variable associated with MDS. For participants having < 10 teeth including teeth replaced in each jaw, the significant factor was “premolar region sufficient.” Overall, lower MDS was associated with increasing number of teeth, as well as with increasing number of teeth replaced by dental prostheses. Conclusions In this population of institutionalized dentate elderly, masticatory ability was significantly associated with dental and prosthodontic status. Clinical relevance For institutionalized elderly, having less than ten natural teeth in each jaw is associated with chewing problems. Most important dentition factor is the presence of three to four premolar pairs. Teeth added by partial removable dental prostheses compensate impaired masticatory ability due to tooth loss for 50% compared to natural teeth.

Introduction. Dental impaction represents the group of isolated dental anomalies characterized by retention of a tooth with a fully formed root in the jaw bone, after the eruption period has passed. This anomaly may affect deciduous teeth, permanent or supernumerary teeth causing aesthetic and / or functional disorders. Case report. The case presents a clinical situation of a girl who presented two maxillary teeth impacted (a central incisor and a cuspid) who underwent surgical exposure and orthodontic treatment for their arch alignments. Conclusions. Impacted teeth may produce dental malpositions or root resorption of the adjacent teeth, cysts or chronic local infections, which carry out a surgical orthodontic treatment, complex and for a long term, depending on the clinical situation existing.

Full textAbstract:
ABSTRACT If essential care is thorough, teeth with extensive orthodontically induced dental resorption can have the same endurance as normal teeth. These teeth are subjected to the same disturbances as normal ones, such as dental trauma, dental caries and periodontal disease, all of which are independent of severe dental resorption. Orthodontic retreatments of teeth presenting with extensive orthodontically induced dental resorption must take into consideration that these roots are shorter in length, therefore, they are more prone to root resorption. Conventional movements are not viable in severe resorption, but Orthodontics offer some alternatives, such as; 1) movement of multiple teeth, providing better distribution of force; 2) use of lesser forces along with bodily movements, as opposed to rotation; 3) anchorage using miniplates, which provide more diffuse and equally distributed force and movements upon teeth and bone. Extensive orthodontically induced dental resorption are not an indication for endodontic treatment. These teeth also should not be replaced by osseointegrated dental implants, but they must receive special care, as they must remain in the dental arch indefinitely.

Full textAbstract:
Background: Dental comparison is based on unique characteristics of the teeth (shape and outline, restorations, supernumerary teeth, impacted, fractured teeth etc.). Being the hardest structure in human body, teeth represent an ideal means of identification in situations of advanced decomposition, fire and mass disaster. Orthopantomogram is a broadly applied standard method in today’s practical dentistry and provides a complete view of the teeth and both jaws in one image.AIM: The present study aimed to verify the diversity of dental patterns in Udaipur population based on specific patterns of missing, filled, unrestored (virgin) and impacted teeth using Orthopantomogram.Material and Methods: 300 Dental Orthopantomogram were randomly selected from Pacific Dental College & Hospital, Udaipur and observed for the occurrence of dental patterns. The frequency of occurrence of dental patterns and the diversity in dental patterns were calculated for full dentition, maxilla and mandible.Results: Occurrence of most common dental pattern was formed by 32 virgin teeth, 10.66%. the diversity of dental pattern for full dentition was 99.7%, maxilla was 99.5%, and mandible was 99.49%.Conclusion: The diversity derived from dental patterns is a potentially valuable tool with broad applicability for human identification inspite of the mentioned drawbacks.

Full textAbstract:
Aim. To determine the role of complications of caries of deciduous teeth in the structure of pathology of hard dental tissues. Methods. Conducted was a dental examination and treatment of 1016 children aged 1 to 9 years who were treated at the children’s dental clinic. Results. The overall prevalence of caries was 78.64%, the need for treatment was - 73.82%. Complications of dental caries were found in 60.83% of cases. 55.21% of children had temporary tooth pulpitis, 41.24% - had a diagnosis of «periodontitis». Premature removal of deciduous teeth was performed in 12.11% of cases. At an early age (1-3 years) 47.35% of the children were registered as having affected deciduous teeth, almost half of them had teeth with complicated dental caries (20.0%). In children of preschool age (4-6 years) the prevalence of caries disease was 92.17%, and complications of caries were diagnosed in 78.80% of cases. In the group of primary school children (7-9 years) the proportion of children with affected temporary teeth was 98.34%. 86.77% of children had deciduous teeth with complications of caries. Every child who comes to children’s dentist at an early age, already has an average of 2.33 affected teeth, in the preschool age - 4.8 teeth, in the primary school years - 5.02 affected deciduous teeth. In evaluating the intensity of dental caries it was established that each child had on average 1.96 teeth with uncomplicated caries and 2.08 teeth with caries complications. Treatment or retreatment was necessary in 70.69% of cases of affected teeth, of them uncomplicated caries accounted for 35.96%. Conclusion. Revealed was a high prevalence and need for treatment of complicated caries of deciduous teeth starting from an early age.

ABSTRACTObjectives: The aim of this study was to compare the differences in self-reported oral health attitudes and behaviour between preclinical and clinical dental students in Turkey using Hiroshima University Dental Behavioural Inventory (HU-DBI). Methods: A Turkish version HU-DBI questionnaire with additional 7 questions, totally 27 items, was distributed among 1022 dental students. Results: The response rate was 75% (486 preclinical and 278 clinical students). Significantly higher (P=0.000) percentage of the preclinical students, compared to clinical students, worry about colour of their teeth, are bothered by the colour of their gums, put off going to the dentist until they have a toothache; think that their teeth are getting worse despite their daily brushing, it is impossible to prevent gum disease with tooth brushing alone, and they cannot help having false teeth when they are old. Moreover, the preclinical students more frequently agree on that their gums tend to bleed when they brush their teeth, they use a toothbrush which has hard bristles, and they don’t feel they’ve brushed well unless with strong strokes (P=0.000). However, a higher proportion of clinical students compared to preclinical students brush each of their teeth carefully, think that they can clean their teeth without using toothpaste, have had their dentist tell them that they brush very well (P=0.000). The HU-DBI score of clinical students (7.47±1.86) was significantly (P=0.000) higher than preclinical students (6.00±1.86). Conclusions: Dental students should have a comprehensive program, including their self-care regimes, starting from their first year of education. (Eur J Dent 2011;5:253-259)

Full textAbstract:
Associations of numbers of teeth present and of missing teeth with Alzheimer’s disease were cross-sectionally analyzed using the National Database of Health Insurance Claims and Specific Health Checkups of Japan. Dental care claims data of patients aged 60 years or older diagnosed with periodontitis (n = 4,009,345) or missing teeth (n = 662,182) were used to obtain information about the numbers of teeth present and of missing teeth, respectively, and they were combined with medical care claims data including the diagnosis of Alzheimer’s disease. Numbers of teeth present and of missing teeth excluding third molars were calculated using the dental formula in the claims for periodontitis and missing teeth, respectively, and categorized into three groups each. Percentages of subjects treated for Alzheimer’s disease with 20–28, 10–19, and 1–9 teeth present were 1.95%, 3.87%, and 6.86%, respectively, in patients diagnosed as having periodontitis, and those treated for Alzheimer’s disease with 1–13, 14–27, and 28 missing teeth were 2.67%, 5.51%, and 8.70%, respectively, in patients diagnosed as having missing teeth. Logistic regression models using treatment for Alzheimer’s disease as an outcome variable and adjusting for age and sex showed that odds ratios (95% confidence intervals) for patients with 10–19 and 1–9 teeth (reference: 20–28 teeth) were 1.11 (1.10–1.13) and 1.34 (1.32–1.37), respectively, (p<0.001), in patients diagnosed as having periodontitis, and odds ratios (95% confidence intervals) for patients with 14–27 missing teeth and 28 missing teeth (reference: 1–13 missing teeth) were 1.40 (1.36–1.44) and 1.81 (1.74–1.89), respectively, (p<0.001), in patients diagnosed as having missing teeth. In conclusion, the results of the present study using Japanese dental claims data showed that older people visiting dental offices with fewer teeth present and a greater number of missing teeth are more likely to have Alzheimer’s disease.

Full textAbstract:
Acceptable therapeutic protocol in dentistry depends on the outcomes obtained with follow up. Operative procedural errors (OPE) may occur and they represent risk factors able to compromise a tooth or a dental implant. The aim of this study was to detect the OPE in endodontically treated teeth and dental implants, using cone beam computed tomography (CBCT).Eight hundred and sixteen CBCT exams were performed between January 2009 and October 2010, and only those which presented endodontically treated teeth and/or dental implants were selected. The sample was as follows: 195 CBCT exams (n=200 teeth and 200 dental implants), 72 male, 123 female, with mean age of 51 years.In endodontically treated teeth, OPE included underfilling, overfilling, and root perforation; OPEin dental implants were thread exposures, contact with anatomical structures, and contact with adjacent teeth. Kolmogorov-Smirnov test was used for statistical analysis, with significance level set at α=0.05. Underfilling, overfilling, and root perforations were detected in 33.5%, 8% and 4.5% of the teeth, respectively. Dental implants with thread exposures, contact with important anatomical structures and contact with adjacent teeth were seen in 37.5%, 13% and 6.5% of the cases, respectively. OPE were detected in endodontically treated teeth and dental implants, and underfilling and thread exposures were the most frequent occurrences, respectively.

Full textAbstract:
Background: “SOS teeth” are defined as the first priority teeth for treatment, that have distinct cavitation reaching the pulp chamber or only root fragments are present. Objectives: To assess the prevalence and distribution of SOS teeth with regard to age and sex difference among young to middle-aged adults. Methods: This is a cross-sectional records-based study of a nationally representative sample, consisting of young to middle-aged military personnel, who attended the military dental clinics of the Israel Defense Forces (IDF) for one year. SOS teeth definition corresponds to code number 6 of the “Caries Assessment Spectrum and Treatment (CAST)” as an instrument to assess dental caries. Data pertaining to age and sex were drawn from the central demographic database and that of SOS teeth were obtained from the Dental Patient Record (DPR). Results: The study included 132,529 dental records. The prevalence of patients with SOS teeth was 9.18 % (12,146/132,323). The number of teeth that were found to be SOS teeth was 18,300, i.e., 1.5 SOS teeth per “diseased” patient (18,300/12,146). The mean number of SOS teeth per the whole study population was 0.14 ± 0.52 and the range was 0–20. The mean number of SOS teeth per patient had a statistically significant negative correlation with age (p < 0.001; Odds Ratio (OR) = 0.997; 95% confidence interval: 0.997–0.998) and with male sex compared to females (p < 0.001; OR = 1.029 confidence interval: 1.023–1.036). Conclusion: Assessment of first priority SOS teeth may be part of the dentist’s work-up. It provides dentists and health authorities with useful information regarding urgent dental care needs to plan dental services.

Full textAbstract:
Extracted human teeth is the preferred choice for preclinical training as it simulates the clinical scenario as compared to artificial teeth. However, the increase in the number of dental undergraduates might cause an imbalance in the demand and supply of extracted human teeth. Not only that, extracted human teeth are also needed by researchers for the development of dentistry (e.g. dental pulp stem cells research). This study aimed to evaluate the socio-demographic and preclinical training factors associated with the willingness to donate teeth among dental students of a selected university in Malaysia. The results of thisstudy show that the majority of students were willing to donate their teeth after extraction for educational purposes, followed by keeping their tooth, leaving it behind as clinical waste anddonating it to research. Further research is recommended to determine the willingness of the community or public to donate their teeth to meet the demand for dental schools and researchers in Malaysia.

The Iberian lynx is an endangered felid that has been subject to an intensive ongoing conservation program in an attempt to save it from extinction. Identification of dental pathologies could play an important role in the survival of this endangered species. The objective of this study is to evaluate the dental pathologies (congenital, developmental, and traumatic abnormalities) of this species of felid. Skulls of 88 adult specimens of the Iberian lynx ( Lynx pardinus) from the Doñana Biological Station [Estación Biológica de Doñana-Consejo Superior de Investigaciones Científicas] (EBD-CSIC), Seville, Spain, were examined macroscopically, and full-mouth dental radiographs of all specimens were performed. Presence, absence, form of teeth, number of roots, supernumerary teeth, and persistent deciduous teeth were evaluated. The presence of attrition/abrasion, tooth fractures, enamel hypoplasia/hypomineralization, endodontic disease, intrinsically stained teeth, and other traumatic findings were also evaluated. Abnormal grooves and dilacerations were the most common abnormalities seen in the roots of teeth. Two hundred and fifteen fractured teeth (11.3% of evaluated teeth) were detected, and mainly complicated fractures were noted in maxillary canine teeth (24.2% of fractured teeth) and mandibular canine teeth (16.7% of fractured teeth). Endodontic disease was present in 3.9% of the teeth examined. Intrinsic tooth staining was assessed in 8.5% of evaluated teeth. Of all teeth examined, 831 teeth (43.7% of evaluated teeth) exhibited some type of attrition/abrasion. Our study concluded that there is a high prevalence of dental fractures and attrition/abrasion with associated endodontic disease that could lead to impaired hunting ability as well as a threat to overall health and subsequent survival of this endangered species.

Objectives: To evaluate the pattern and reasons for permanent tooth extractions in an adult patient seeking free dental care at clinics of the University of Science and Technology of Fujairah, UAE. Methods: The current retrospective study involved patients who had a dental extraction in the student dental clinics of the University of Science and Technology of Fujairah. Data of 1000 randomly selected extractions were collected from the archive of the university dental clinics. Results: Males had more teeth extracted (88.3%) than females. The most frequent extraction (58.9%) was in individuals of 30-49 years old range. Dental caries was the major reason (44.6%) of extractions, followed by wisdom teeth related extraction (23.4%), periodontal disease (18.1), failure of endodontically treated teeth (8.7%), prosthetic reasons (2.6), orthodontic reasons (1.7%), and trauma (0.9%) respectively. The most extracted teeth were the maxillary posterior teeth (45.6%), followed by mandibular posterior teeth (38.2%); then, maxillary anterior teeth (8.8) and lastly, were the mandibular anterior teeth (7.4%). Caries was significantly more frequent in female gender (χ2= 250.126; p=.000), while the periodontal disease was more common in male gender (χ2 = 146.790; p=.000). Conclusion: Caries is the principal reason for tooth extractions, followed by wisdom teeth related problems and periodontal disease. There is an increasing percentage of tooth extraction due to periodontal disease with both aging and male gender. Caries was the more frequent reason for extraction in all quadrants, except the lower anterior teeth in which periodontal disease was the more frequent reason. Lastly, anterior teeth were retained in the oral cavity more than posterior teeth.

Harp seal fetuses and neonates were examined to determine the development, resorption, and eruption characteristics of deciduous and permanent dentition. Early September fetuses had recently formed, deciduous teeth only. By early December the deciduous dentition was robust and enameled. Permanent teeth were also present. In late December the roots of the deciduous teeth were being resorbed and the permanent dentition was larger and better developed. About 80% of the deciduous teeth were resorbed by birth in March. The rest were resorbed or shed after birth. The pattern of permanent tooth eruption was not correlated with pup age but the total number of teeth erupted increased significantly with increasing pup age, from 38% in newborns to 100% in weaned pups about 3 weeks old. The neonatal line formed at birth rather than at weaning or the onset of moult.

Objective: This retrospective study aims to evaluate the prevalence of dental anomalies in permanent teeth as a result of a trauma concerning the predecessor primary teeth. Study design: A total of 241 records of children (118 males and 123 females, mean age 3.62 &plusmn; 1.40) affected by trauma on primary teeth were analyzed. All patients were recalled to evaluate the status of the permanent successor teeth by clinical and radiographic investigations. Results: Out of 241 patients, 106 patients (for a total of 179 traumatized primary teeth) presented at the recall. Dental anomalies on successor permanent teeth were detected in 21 patients (19.8%), for a total of 26 teeth (14.5%) and 28 anomalies. Anomalies of the eruptive process were the most observed disturbances (60.7%), followed by enamel hypoplasia (25%) and white spots (14.3%). A higher percentage of anomalies on permanent teeth was observed when trauma occurred at an age less than 36 months (38.5% of cases). Intrusive and extrusive luxation were related with the most cases of clinical disturbances in the successor permanent teeth. Conclusions: The results of this study highlight the risk of dental anomalies after a trauma in primary dentition, especially in early-aged children and in case of intrusive luxation.

Introduction. The most of dental practitioners have some doubts about teeth bleaching safety in patients with teeth abfractions and gingival recession. Aim. Assessment of professional oral debridement and teeth bleaching safety in patients with teeth abfractions and gingival recession. Material and methods. Randomized controlled trial was done in two groups of 30 patients with teeth abfractions and gingival recession. In group 1 oral debridement and professional dental bleaching were performed. Abfractions and recessions were isolated with a liquid dam. In group 2 oral debridement was made. The vertical size of recession, Tooth Wear Index and Schiff air sensitivity index were evaluated. Results. After 12 months the enlargement of wedge defects was pronounced in 5 teeth in group 1 and in 7 teeth in group 2. The enlargement of the gingival recession was marked in 6 teeth in group 1 and in 8 teeth in group 2. No statistical difference between groups was seen. In group 1 after teeth bleaching the sensitivity was present in 240 teeth (40%), after 14 days amount of teeth with sensitivity reduced to 110 (18.3%). In group 2 after oral debridement, the sensitivity was present in 250 teeth (41.7%), after 14 days amount of teeth with sensitivity reduced to 239 (39.8%). Conclusion. The teeth bleaching has no effect on dental abfractions and gingival recession.

Full textAbstract:
Dental caries is an infectious disease that can occur in children, sometimes as soon as the teeth eruption starts. Nanotechnology provides effective strategies in prevention and treatment of dental caries. The purpose of this study was to determine the effectiveness of the addition of silver nanoparticles to a fluoride varnish for the remineralization of primary teeth with white spot lesions. A trial was carried out in children with dental demineralization (white spot lesions) on both maxillary dental teeth. One of the teeth received three applications of a fluoride varnish with silver nanoparticles, and the other one, three applications of the same varnish without the silver nanoparticles. We measured the mineral content of the teeth with a laser cavity detection device (DIAGNOdent®) before the first application of the varnishes, and 3 months after the last application. The results show significant differences between teeth treated with silver nanoparticles. Teeth have been treated with fluoride varnish added with silver nanoparticles seemed to enhance dental structure than teeth treated with conventional varnish, and this effect was also found between basal and final measurements in this group. The fluoride varnish added with silver nanoparticles seems to be more effective in the dental remineralization. This strategy may be used as a prophylactic measure to avoid development of caries.

SummaryIntroduction. Dental implant therapy has become a popular method of replacing one or more missing teeth. Osseointegrated dental implants have been studied from histological, microbiologic and biomechanical point of view, but the neurophysiologic integration of the implants and the supported prostheses has received less attention. The sensory mechanism of dental implants is qualitatively different from that of natural teeth. Psychophysiological tests are used to determine the tactile sensibility perceived with the implants and teeth.Aim of the study. The purpose of this study was to compare tactile sensibility of natural teeth and osseointegrated dental implants.Material and methods. Forty-three patients were included in the study. Natural teeth were divided into two groups: non endodontically treated teeth (NETT) and endodontically treated teeth (ETT). Load tests were done by a computer-controlled pressure sensitive device („Power Lab“ Data Acquisition System - model 4/25T, sensor - model MLT003/D; ADInstruments), specially modified for intraoral use. Pushing forces were applied parallel to the vertical axis of teeth and implants. The patient held a signal button which he/she activated as soon as touch was sensed. At this moment the computer registered passive absolute tactile threshold - measured in Newtons. The mean values of passive absolute tactile threshold for natural teeth and dental implants were calculated. Comparison of the mean values was performed by the means of t-test.Results. Passive absolute tactile threshold for osseointegrated dental implants was 2.39 N (SD=1.92), and for teeth - 0.67 N (SD=0.72), for non endodontically treated teeth it was 0.63 N (SD=0.72) and for endodontically treated teeth - 0.73 N (SD=0.69). The differences in mean values were statistically significant (p<0,0001) except for mean values of NETT vs. ETT.Conclusion. This study shows that patients with osseointegrated implants subjectively feel “touch” sensation when greater force is applied compared with natural teeth.

Tooth color and the correlation of the compostion of dental enamel with color were investigated in samples of teeth from two medieval Serb cemeteries. Differences in the composition of apatite crystals in the dental enamel of the two samples were found. Color ranges of teeth from the two samples differ in hues and chromas. This result suggests that enamel composition may have an influence on the color of teeth. The prevalence of chlorapatite in enamel causes tooth color to be closer to red and of higher chroma than teeth whose enamel consists of hydroxylapatite. No evidenc indicated that soil ingredients were incorporated into the dental enamel of either sample.

Full textAbstract:
Supernumerary teeth are teeth that exceed the normal dental formula. Their prevalence in the permanent dentition is 1–14% and they occur more frequently in maxilla with a sex ratio of 2 : 1 in favor of males. They are often associated with syndromes but there are examples of nonsyndromic multiple supernumerary teeth reported in the literature. CBCT is usually the best exam for radiographic diagnosis and treatment planning, because it provides 3D information about location and morphology of supernumerary teeth. This paper reports a rare case of four supernumerary teeth in a nonsyndromic 9-year-old boy. The peculiarity of this case is that two more exceeding teeth were found during surgical procedure. After extraction, all the teeth underwent a histological undecalcified processing for light microscopical examination. The two “ghost” supernumerary teeth seemed to be primordial dental germs, possibly resulting from an altered odontogenic process. After supernumerary teeth extraction, X-rays and exfoliation monitoring are recommended, since permanent retained teeth often erupt naturally or, at least, improve their condition. Radiographic follow-up is also useful in order to assess the formation of further teeth due to the hyperactivity of the dental lamina.

Background: The anatomy of the canine oral cavity and its variations should be understood to facilitate clinical and surgical approaches. Several conditions can be identified during inspection of the oral cavity, including persistent deciduous teeth, enamel hypoplasia, gingival retraction, tooth abrasion and mobility, absence of dental elements, and periodontal disease. The aim of the present study was to determine the occurrence of dental disorders in dogs older than one year, from the microrregion Ilhéus - Itabuna, Bahia, Brazil. Materials, Methods &Results: A total of 74 dogs were evaluated immediately prior to surgical procedures for periodontal disease treatment. After visual inspection and examination with a millimeter probe, the dogs were classified into three groups according to the degree of periodontal disease. All other findings were recorded on an odontogram. Of the 74 dogs, 23 were classified as mild periodontal disease (mean age, 3.6 years), 26 as moderate periodontal disease (mean age, 5.7 years), and 25 as severe periodontal disease (mean age, 9.7 years). There was significant correlation (0.7 p ≤ 0.01) between age and severity of periodontal disease. Fifteen of the 74 dogs did not present any other dental disorder than periodontal disease. Of the remaining 59, nine showed a single dental problem, and 50 had more than one dental problem. Six dogs (of the breeds Pinscher, Yorkshire Terrier, and Lhasa Apso) had deciduous teeth. Of the nine deciduous teeth, all were canine (dental elements 104, 204, and 304). Ten dogs had dental fractures and of the 11 fractured teeth, three were canine (dental elements 104 and 404). Dental wear was observed in 25 dogs (154 teeth). Of the evaluated dogs, seven showed furcation defects and 10 had teeth mobility. Dental absence was observed in 47 dogs.Discussion: In the present study, increased age had a positive correlation with the degree of periodontal disease; this is consistent with reports in the literature, which indicate severity of periodontal disease increases with advancing age. In one of the three cases of enamel hypoplasia, the dog owner reported that the dog presented clinical signs compatible with distemper before the teeth changed, corroborating studies that showed that this virus can act on the enamel cells causing hypoplasia lesions. All the deciduous teeth found were dental elements 104, 204, and 304, consistent with literature reports that these teeth are among the most frequently affected by this condition. In the present paper, of all the teeth examined, the canine teeth presented the majority of fractures. Canine teeth are used for grasping and tearing food, and defense, and are more vulnerable to fractures. Dental wear was observed in many dogs in the present study, presenting as loss of dental surface caused by friction, abrasion, or erosion from a variety of causes. Dental wear may be considered as a physiological process as long as it does not compromise function. Dental mobility is an important clinical sign of periodontal disease and generates pain and discomfort to the patient; in the presence of advanced periodontitis, there is a marked loss of periodontal tissues, including alveolar bone, which is an irreversible process. As the dogs evaluated in the present study were older than one year, any absent teeth could be verified as being due to periodontal disease. In conclusion, disorders of the oral cavity have high prevalence in dogs and must receive special attention to be properly diagnosed and treated.

Full textAbstract:
Silver diamine fluoride (SDF) is a dental biomaterial used to arrest dental caries. To better understand SDF’s mechanism of action, we examined the localization of silver within the tissues of SDF-treated teeth. Carious primary teeth fixed within 2 min of SDF application (SDF-minutes, n = 3), at 3 wk after SDF application in vivo (SDF-weeks, n = 4), and at 2 y after multiple SDF applications in vivo (SDF-multiple, n = 1) were investigated in this study. Carious primary teeth without SDF application (no-SDF, n = 3) served as controls. Mineral density and structural analyses were performed via micro–X-ray computed tomography and scanning electron microscopy. Elemental analyses were performed through X-ray fluorescence microprobe and energy-dispersive X-ray spectroscopic techniques. SDF-treated teeth revealed higher X-ray–attenuated surface and subsurface regions within carious lesions, and similar regions were not present in no-SDF teeth. Regions of higher mineral density correlated with regions of silver abundance in SDF-treated teeth. The SDF penetration depth was approximated to 0.5 ± 0.02 mm and 0.6 ± 0.05 mm (mean ± SD) for SDF-minutes and SDF-weeks specimens, respectively. A higher percentage of dentin tubular occlusion by silver or calcium phosphate particles was observed in primary teeth treated with SDF-weeks as compared with SDF-minutes. Elemental analysis also revealed zinc abundance in carious lesions and around the pulp chamber. SDF-weeks teeth had significantly increased tertiary dentin than SDF-minutes and no-SDF teeth. These results suggest that SDF treatment on primary teeth affected by caries promotes pathologic biomineralization by altering their physicochemical properties, occluding dentin tubules, and increasing tertiary dentin volume. These seemingly serendipitous effects collectively contribute to the cariostatic activity of SDF.

Full textAbstract:
Synopsis During evolution, there has been a trend to reduce both the number of teeth and the location where they are found within the oral cavity. In mammals, the formation of teeth is restricted to a horseshoe band of odontogenic tissue, creating a single dental arch on the top and bottom of the jaw. Additional teeth and structures containing dental tissue, such as odontogenic tumors or cysts, can appear as pathologies. These tooth-like structures can be associated with the normal dentition, appearing within the dental arch, or in nondental areas. The etiology of these pathologies is not well elucidated. Reawakening of the potential to form teeth in different parts of the oral cavity could explain the origin of dental pathologies outside the dental arch, thus such pathologies are a consequence of our evolutionary history. In this review, we look at the changing pattern of tooth formation within the oral cavity during vertebrate evolution, the potential to form additional tooth-like structures in mammals, and discuss how this knowledge shapes our understanding of dental pathologies in humans.

Full textAbstract:
Several studies shows that a wide range from 3-16% of dentoalveolar traumatic injuries result in avulsion. The ideal treatment for avulsion would be the reimplantation of the tooth. Thus, it is recommended to replant the tooth as quickly as possible. However, immediate repositioning of teeth is not always possible, so the choice of a suitable storage medium for maintenance of Periodontal Ligament cell viability is of extreme importance for the success of replantation. At the present article are discussed some storage medium and the results published in the international literature.

ABSTRACT High intake of fluoride causes developmental disturbances of tooth enamel leading to dental fluorosis. It produces mottling of enamel and its occurance depends upon the quantity of fluoride ingested and the stage of tooth development. Esthetic management of mottled teeth is planned according to the severity of discoloration and the extent of surface aberrations. A combination of different techniques makes the teeth lighter in shade with a smoother surface. This case report describes the management of fluorosed teeth which is discolored and pitted on the surface by minimally invasive procedures.
