Aims: A descriptive type of cross-sectional study was conducted at the department of Orthodontics & Dentofacial Orthopedics of Dhaka Dental College & Hospital, Dhaka, Bangladesh during January 2010 to December 2012. The aim of the study was to test the hypothesis that there were no differences between adults with class I crowded, class III and class I normal occlusions in respect to width of the maxillary and mandibular arches and gender comparisons. Materials and Methods: In this study, 82 pairs of study models were selected from the patients and students of the Department of Orthodontics and Dentofacial Orthopedics at Dhaka Dental College and Hospital and were divided into three groups. Twenty seven (27) pairs of dental casts with normal occlusion, 25 pairs with class I crowded and another 30 pairs with class III malocclusions that included almost equal numbers of male and female samples. Results: Among different arch dimensions, maxillary arch widths were found to have significantly smaller in class I crowded and class III malocclusions compared to normal class I occlusion. Conclusion: The hypothesis was partially rejected by the findings of the study. It may be suggested that Orthodontist who is aware of these differences in arch dimension will be beneficial to diagnose and make planning of treatment of orthodontic cases more accurately.

Introduction: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders diagnosed by impairments in social interaction and communication with repetitive and restrictive stereotyped behavioral patterns. The Prevalence of autism has been reported to be increased in recent years. This study aimed to assess the prevalence of different types of malocclusion among ASD patients in Isfahan in 2018. Materials & Methods: In a descriptive and cross-sectional trial, 92 ASD patients were studied in the age range of 7-18 years at the center for autism patients in Isfahan. Clinical oral examinations of patients are taken to assess the involved malocclusions (Cl I, Cl II and Cl III malocclusions) and malocclusion traits (deep bite, open bite and cross bite) by an educated dental student under the supervision of an orthodontist under natural light. The data are reported using frequency and percentage indices. Results: Class I malocclusion had the highest prevalence 54.3% (50) among ASD patients and the prevalence of class II and class III were found to be 19.6% (18) and 7.6% (7) respectively. The frequency of malocclusions traits of deep bite, cross bite and the open bite were 27.2% (25), 18.5% (17) and 7.6% (7) respectively. Among of the total patients, 65.2% (60) showed normal bite and 18/5% (17) showed Normal occlusion. Conclusion: ASD patients showed class I, class II and class III malocclusions from the most to least frequency and the most frequent malocclusion traits were also deep bite, cross bite and open bite respectively.

Aim: To investigate the correlation between anterior tooth size discrepancies among Angle's Class l, ll, lll malocclusions and corresponding normal occlusion, as well as their prevalence in Bangladeshi population. This study would act as a reference for diagnosis, treatment planning and assessment of prognosis in some orthodontic cases. Methods: This cross sectional study was conducted in the Department of Orthodontics & Dentofacial Orthopedics, Dhaka Dental College & Hospital. A total number of 200 subjects were selected in Angle's Class l, ll, lll and corresponding normal group. Each group had 50 subjects with males and females. A chi-square test was performed to statistically compare the prevalence of anterior tooth size discrepancies among Angle's Class l, ll, lll malocclusions and corresponding normal occlusion and two genders. Analysis of variance was used to compare the mean Bolton anterior tooth size ratios as a function of angle classification and gender. Statistical differences were determined at the 95% confidence level (p< 0.05). Results: No significant difference was observed in the mean Bolton anterior ratio between normal group and class-I malocclusion group (p = 0.343). Significant differences were observed between Class-II malocclusion and normal group (p=0.001), and also between Class-III malocclusion and normal group (p = 0.001). Individuals with Angle Class lll and Class ll malocclusions showed significantly greater prevalence of tooth size discrepancy than Class l malocclusion and corresponding normal group. Conclusion: The great diversity and ethnic mix of Bangladeshi population should alert our orthodontist to use Bolton analysis as an important diagnostic tool and become aware of the moderate variations that may be present and treated. It may somehow guide planning of this type of study in future. DOI: http://dx.doi.org/10.3329/bjodfo.v1i2.15982 Ban J Orthod & Dentofac Orthop, April 2011; Vol-1, No.2, 1-4

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.

Abstract This cross-sectional study aimed to evaluate the primary canine and the primary molar relationship in 205 (90 girls and 115 boys) three to six year-old Turkish children with the primary dentition in centric occlusion according to gender and age. In terms of the molar relationship, Class I was represented by 88.29% of all children who agreed to participate in the study, followed by Class II (7.31%), and Class III (4.4%). In terms of the canine relationship, Class I was represented by 87.8% of the sample, followed by Class II (7.8%), and Class III (4.4%). A statistically significant difference was found between age and both the canine and molar relationships (p<0.005), and a positive correlation was confirmed among them. However, the difference and correlation between the gender and the canine and molar relationships were not significant. Citation Yilmaz Y, Gürbüz T, Şimşek S, Dalmiş A.

Introduction: The purposes of this study were to seek for overall ratio (OR) and anterior ratio (AR) patients data in normal occlusion and Angle&rsquo;s malocclusion studies, and to assess if such results support Bolton&rsquo;s standards as general references.&nbsp;Methods: Pubmed, Medline, CENTRAL and Scholar databases were searched up to February 2018 (CRD42018088438). Gray literature was explored through OpenGray. Non-randomized clinical studies, published in English and assessing Bolton&rsquo;s OR and AR in normal occlusion and Angle&rsquo;s malocclusion groups (Class I, Class II, Class II division 1, Class 2 division 2, Class III) patients were included. OR and AR means and standard deviations (SD) were collected. Potential covariates (study design, publication year, country where the study was conducted, number of cases, gender, mesiodistal measurement method, and calibration method) were also extracted. The National Health Heart Lung, and Blood Institute&rsquo;s Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to assess each included studies quality. Pairwise Random-Effects and Multilevel Bayesian Network Meta-Analyses were used to synthesize available data.&nbsp;Results: Fifty-two observational studies were included (8872 participants; male/females 2674/3272; 16 studies lacked gender information). For normal occlusion, global pooled estimates for OR and AR means were 91.74% (95% CI: 91.37-92.10) and 78.24% (95% CI: 77.85-78.63), respectively. We could identify on Angle&rsquo;s Class III patients meaningful OR and AR mean deviations from normal occlusion (0.89, 95% credible interval [CrI], 0.66-1.12, and 0.66, 95% CrI, 0.38-0.94, respectively), while on Class I patients we found a meaningful mean deviation from normal occlusion only for OR (0.25, 95% CrI, 0.03-0.47). Concerning gender impact, male patients presented higher OR (0.30, 95% CI 0.00-0.59) and AR (0.41, 95% CI 0.00-0.83) mean values than females in Class I.&nbsp;Conclusions: The results show that global pooled OR and AR mean values for normal occlusion patients are slightly above Bolton&rsquo;s original values. Class I, for OR mean values, and Class III, for both OR and AR, are proportionally larger than normal occlusion patients. Gender had almost no impact on teeth mesiodistal proportion.
