The aim of this paper was to determine the prevalence of malocclusions in 12-year-old schoolchildren from Cuenca, Ecuador. A cross-sectional study was carried out, including a clinical examination of 181 schoolchildren aged 12 years, who were randomly selected from the schoolchildren population. We assessed the presence of malocclusions using the Angles classification. The analysis was performed in the program EpiInfo 7.2. The majority of the patients presented malocclusions (91.7%). There is no significant difference between public and private schools and the male sex was slightly more affected. There was a predominance of the Class II division 1 (30.4%), followed by Class III (25.4%), and Class I (24.9%), with the lowest prevalence reported for Class II division 2 (11%). A high rate of malocclusion was found in in 12-year-old schoolchildren from Cuenca, Ecuador, in both males and females. The dominant malocclusion in this study was Class II division 1.

The dentoskeletal characteristics of Class II malocclusion subjects were evaluated using cephalometric radiograph and dental cast of 60 untreated patients. The sample included 30 Class II Division 1 and 30 Class II Division 2 malocclusion patients. The inter-canine, inter-premolar, inter-molar, inter-canine alveolar, inter-premolar alveolar, inter-molar alveolar widths are measured on study models. The result showed statistically significant difference between the groups for mandibular inter-canine width only. The cephalometric analysis revealed that SNB angle was responsible for the skeletal sagittal difference between the two groups except for the position of maxillary incisors. No basic difference in dentoskeletal morphology existed between Class II Division 1 and Class II Division 2 malocclusions.

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.

Aim : To evaluate the transverse discrepancy in different malocclusion groups. Also to test the hypothesisvthat models with Class II division 2 malocclusion may have mean maxillary arch widths significantly smaller than those with normal occlusions and significantly larger than those with Class II division 1 malocclusion. Thus the proposed study will generate interest among the orthodontists for further study over the transverse discrepancy of our patients and guide them to establish effective treatment strategy and their management.Methods:  This study was a cross  sectional  study conducted among the dental casts of 150 patients and  students of the Department of Orthodontics and Dentofacial Orthopedics, Dhaka Dental College and  Hospital. Both male and female were included.  The first group consists of 50 pair of study models with  permanent dentition and diagnosed as Class I (normal) occlusion. The second group includes another 50 pair of dental casts with permanent dentition and diagnosed as Class II division 1 malocclusion . And third group includes another 50 pair of dental casts with permanent dentition and was diagnosed as Class II division 2 malocclusion. This group of malocclusion was again subdivided into two categories, Class II division 2 malocclusion with crowding and Class II division 2  malocclusion without crowding. The Student’s t –test was used to analyze the data. In this analytical test the level of significance p value <0.05 was considered significantResults: No Statistically significant difference was observed in the maxillary inter canine, inter first  premolar and inter first molar widths between class-I and Class-II div-1. Significant differences were  observed between two groups. In case of mandibular inter first molar widths  (p value = 0.001), and also  differences in case of mandibular inter canine, inter first premolar and inter first molar widths between  Class-I and Class II div 2 malocclusion  p value respectively .01, 0.002,0.01.Conclusion: This study helps in determining possible differences in the dental arch widths of Bangladeshi people in  Class II div 2 adults compared to adults with Class II div 1 and normal occlusion may be an  important aid in further understanding of dentoalveolar characteristics of these conditions, as well as  improving their management.Ban J Orthod & Dentofac Orthop, April 2013; Vol-3, No.2

ABSTRACT Objective: To assess the volume and morphology of the middle region of the pharynx (MRP) in adolescents with different anteroposterior craniofacial skeletal patterns. Methods: One hundred twenty-six patients (56 male and 70 female), who had cone-beam computed tomography (CBCT) within their records, were selected for this cross-sectional study. Participants were classified, according to their ANB angle value, in Class I (1o ≤ ANB ≤ 3o), Class II (ANB > 3o) and Class III (ANB < 1o). The total volume (tV), minimum axial area (AxMin) and morphology of the MRP and its subdivisions - velopharynx (VP) and oropharynx (OP) - were characterized by CBCT and 3-dimensional image reconstruction software. Intergroup comparisons were performed by ANOVA and Tukey post-hoc tests. Correlations between tV and Axmin with the ANB angle values were tested using linear regression analysis, considering sex as covariable. Results: Statistically significant difference between groups were observed in tV only for the VP region; Class II individuals presented significantly lower tV (6863.75 ± 2627.20 mm3) than Class III subjects (9011.62 ± 3442.56 mm3) (p< 0.05). No significant differences were observed between groups for any other variable assessed, neither in MRP nor in the OP region (p> 0.05). A significant negative correlation was evidenced between tV and Axmin and the ANB angle values; sexual dimorphism was observed for some variables. Conclusions: Class II subjects have smaller tV in the VP region. tV and Axmin tend to decrease in all evaluated regions when the ANB angle values increase.

ABSTRACT Background Prevalence of malocclusion varies in different parts of a diverse country like India. Aims To determine the prevalence of malocclusion in population of Jaipur city, Rajasthan, India, as well as subjects views regarding the most important factor for seeking orthodontic treatment by patients who have malocclusion. Materials and methods The sample consisted of 700 subjects (373 males and 327 females) with age group of 15 to 30 years. Subjects were randomly selected and none of them had received orthodontic treatment previously. The subjects who showed bilateral Angle's class I molar relationship with acceptable overjet, overbite and well-aligned arches or minimal crowding were considered to have normal occlusion. The subjects with malocclusion were classified into four groups according to Angle's classification, i.e. class I, class II division 1, class II division 2 and class III malocclusions. Results About 74.57% of population was found to have malocclusion. Among these subjects, 52.57% subjects were diagnosed with class I malocclusion, 12.57% with class II division 1 malocclusion, 8% with class II division 2 and remaining 1.42% had class III malocclusion. No statistically significant differences were found between male and female subjects. Conclusion Among class I malocclusion characteristics, Angle's class I type 1 malocclusion was statistically significantly found to be the most prevalent type of malocclusion. As far as the most important factor for seeking orthodontic treatment was determined, a desire of enhancing facial appearance followed by a desire of attaining straight teeth was considered to be the chief motivational factor among this population.
