Abstract:
Objective: To investigate the distribution of abnormal occlusion of permanent dentition in adolescents. Methods: 304 Junior university students aged 16- 18 years old were investigated with their occlusion casts according to the Angle classification and the relationshop of over-jet and over-bite in both anterior and posterior teeth. Asymmetrical Angle category was given to those whose bilateral classifications were different. Results: 19.73% of the subjects were found with normal occlusion. Among the abnormals 58. 05%, 8. 90%, 8. 90% and 24. 15% were found with Angle Ⅰ, Ⅱ, Ⅲ and asymmetrical Angle category respectively. Anterior edge-to-edge relationship, cross-bite, deep over bite, deep-over jet and open bite were 12.71 %, 11.02 %, 5.08%, 5.08 % and 2.12% respectively, posteriorly cross-bite, reverse crosss bite and combination of the two were 19.07%, 17.37% and 0.85 % respectively. Conclusion: The asymmetrical Angle malocclusion and abnormal over-jet and over-bite of both anterior and posterior teeth stand a large ratio in Junior university students.
