Abstract

Objective: To analyse the association between the British standards institute's Incisor classification of malocclusion and the Angle's classification of malocclusion. In addition to this, applicability of British standards institute's incisor classification in orthodontic diagnosis and treatment planning was also explored.

Materials and Methods: The study was conducted at the Department of Orthodontics and dentofacial Orthopedics, Tamil Nadu Government Dental College and hospital, Tamilnadu, Chennai. Samples of randomly selected two hundred study models were divided into four groups based on British standards institute's incisor classification and Angle's classification. Cross-tabulation of both the classification was done and the data was statistically analysed using chi-square test.

Results: On the whole, statistically significant association (p< 0.001) exists between British incisor classification and Angle's classification. Also, statistically significant association was found between British incisor classification and Angle's classification in class I and class III groups (p< 0.001 and p< 0.05 respectively). However, there was no association in class II div I and class II div II groups (p=0.0990 and p=0.8348 respectively).

Conclusion: For complete diagnosis and treatment planning in orthodontics, both these classifications should be considered in describing malocclusion.
