Introduction: Knowledge of the distribution of different malocclusions in a geographic location could help orthodontics better know the problems in that region. Moreover, giving awareness about the problem and treatment possibilities can help people. This study aimed to determine types of malocclusion and dental caries in children aged 11 to 14 years in Roudsar, Iran.
Materials and Methods: In this cross-sectional study, 114 healthy children aged 11-14 years were randomly selected from five schools in Roudsar. To evaluate the prevalence of dental caries and the types of malocclusion, DMFT index and Angle classification were used, respectively. Overjet, overbite, and crowding were secondary assessed. After collecting the information, data was analyzed by SPSS21 using chi-square and t-test. The level of significance was considered less than 0.05.
Results: The prevalence of normal occlusion was 9.3%, cl I malocclusion was 32.7%, cl II div 1 malocclusion was 16.8%, cl II div 2 malocclusion was 4.7%, and cl III malocclusion was 15.9%. The mean DMFT in the children studied was 4.369±2.317. There was a significant difference between DMFT index and gender (P=0.027). There was no significant difference between different types of malocclusion and normal occlusion by gender.
Conclusion: The mean of DMFT index was significantly higher in males compared to females. The most common malocclusion was cl I malocclusion and there was no significant relationship between the types of malocclusion and dental caries. Also, no relation was found between gender and malocclusion.
