Correlation between lip print patterns and skeletal class I and II malocclusions - A tool to diagnose early.

BACKGROUND

Cheiloscopic analysis has been shown to have close association with skeletal malocclusion. Hence, aim of the present study was to explore any association between lip prints patterns and skeletal class I and II malocclusions.

MATERIALS AND

METHODS

A study sample of 90 subjects aged between 18 and 25 years was selected from individuals opting for orthodontic therapy. Skeletal malocclusion using ANB angle was assessed using lateral cephalograms while lip print patterns were analyzed using the cellophane-adhesive method. Statistical analysis: Mean ± SD was analyzed and significance was assessed using ANOVA.

RESULTS

Skeletal class I group showed more branched pattern (29%). Other patterns in decreasing order were intersected (25%), reticular (24%), and vertical lip patterns (22%), while the skeletal class II group showed branched pattern as most common (32%), followed in decreasing order by reticular (29%), intersected (25%), and vertical lip patterns (14%). No statistical significance was derived between lip pattern type and skeletal malocclusion.

CONCLUSION

Lip print patterns are important indicators of malocclusion and can help in predicting the same at an earlier stage.
