- Abstract
Aim: The aim of this study is to find out the prevalence of malocclusion in Malaysian adolescents aged 13–17 years. Materials and Methods: A sample of 100 adolescent school children in Malaysia, both male and female, with the age ranging from 13 to 17 years was randomly selected for a dental examination. None of the subjects had previous orthodontic treatment, and all had a permanent dentition. The inclusion criteria of the study include: (i) No previous orthodontic treatment done, (ii) permanent dentition present with no remaining deciduous teeth, and (iii) all had their first permanent molars. A full clinical examination was carried out using mouth mirror and light to evaluate the anteroposterior molar relationship, crowding, overjet, overbite, crossbite, and midline diastema. Results: About 93% of the population had malocclusion out of which 80% had Class I, 8% had Class II, and 12% had Class III malocclusion. Class II occlusion was most prevalent in Indians (17.4%) and Class III occlusion had a higher prevalence in Chinese (17.9%) and Malays (12.2%). Frequency of crowding was 70% and had increased prevalence in Malays (77.6%). Normal overjet and overbite were seen in 44% and 50% of subjects, respectively. About 6% of the subjects had midline diastema. Crossbite was seen in 32% of the subjects. Conclusion: Malocclusion is a widespread phenomenon among Malaysian adolescents. Prevalence of Class II occlusion was more prevalent among Indians, whereas Class III was seen mostly in Malays and Chinese. Crowding was the most common feature seen in all three ethnic groups.
