Skeletal Malocclusion and Cheiloscopic Pattern in Odisha Population

Abstract

Background: Among the essential diagnostic aids in orthodontics, cheiloscopic analysis is a major soft tissue analysis. Keeping this in mind, the present study was designed to establish any association between the different lip patterns and types of skeletal malocclusions.

Materials and methods: Around 235 study subjects aged between 18-25years were selected randomly from the out patient department records of orthodontics department. The type of skeletal malocclusion (class I, class II div 1, class II div 2, class III) was recorded for every subject based on ANB angle and W angle. This was followed by application of red lipstick and cellophane adhesive tape over the lips to record the individual lip pattern. Chi-square test was considered for test of significance (p<0.05).

Results: Branched lip pattern showed highest prevalence in both skeletal class I and class II div 1 and div 2 malocclusion. While vertical lip pattern was recorded highest in class III subjects. This association was found to be statistically significant with p<0.001.

Conclusion: The study reflects that the lip patterns are definite indicators of skeletal malocclusion.
