disease. While there are evidence that certain features such as stress, traumatic deep overbite, unprotected incisors and impacted teeth may adversely affect the longevity of the dentition. The present study was conducted to assess the prevalence of malocclusion and orthodontic treatment needs in children. Materials & Methods: This study was conducted in the department of Orthodontics on 632 children age ranged 8-14 years of both genders. Children were classified into normal occlusion, Class I malocclusion, Class II div I and class II div II and class III malocclusion. Dewey modification such as type I, type II, type III, type IV and type V was considered. Results: Out of 632 subjects, boys were 330 and girls were 302. The difference was non- significant (P-0.1).Age group 8-10 years had 75 boys and 70 girls. The difference was non- significant (P-1). Age group 10-12 years had 120 boys and 180 girls. The difference was significant (P-0.05). Age group 12-14 years had 135 boys and 52 girls. The difference was significant (P-0.01). Type of focclusion was normal (boys- 32, girls- 30), class I malocclusion (boys- 140, girls- 102), class II div I (boys- 110, girls- 125), class II div II (boys- 38, girls- 31) and class III maloccusion (boys- 10, girls- 15). The difference was significant (P<0.05). Dewey type I was seen in 60 subjects, type II in 45, type III in 55, type IV in 34 and type V in 48 subjects. The difference was non- significant (P>0.05). Conclusion: Most of the children had class I malocclusion follwed by class II div I. Age group 10-12 years maximum number of children with malocclusion.
Key words: Deep overbite, Malocclusion, Orthodontic.
