Abstract

Objective: To determine Collum angle and crown to root angle of maxillary central incisor in different skeletal
malocclusion.

Study Design: Comparative cross sectional study.

Place and Duration of Study: Orthondontics department, Bolan Medical College, Civil Sandman Hospital,
Quetta, from Jun to Dec 2018.

Methodology: Data sample consisted of 140 lateral cephalograms. Sample consisted of 74 female cephalograms and 66 male cephalograms. The mean age of sampled subjects ranged between 21.62 ± 5.96 years. The Colum angle of the maxillary central incisors in each group was measured. SPSS version 21 was used to enter and process data. Comparison between Class II division 1 and division 2 collum angles was made by applying student t-test.

Results: The average value for Collum angle in class II division 1 sample was 4.38 ± 3.08 with minimum being 0
and maximum 15 degree. The average values for Class II division 2 was 10.52 ± 4.37 with minimum 30 and a
maximum 23 degree.

Conclusion: Maxillary central incisors in all malocclusions had significantly different mean Collum angles from
zero. Paired sample t-test comparison showed that the Collum angle for maxillary central was much higher in
Class II division 2.
