Fluctuating asymmetry in various malocclusions: A thought provoking diagnostic parameter

Abstract

Introduction: The assessment of fluctuating asymmetry has clinical importance in the diagnosis and treatment planning of orthodontic patients. The aim of the study was to assess fluctuating asymmetry in Angle Class I and Class II malocclusions and to assess its pattern in males and females respectively.

Material and Methods: It was a cross sectional study conducted in dental clinic at AKUH during the period of July 2010 to July 2011 on 100 subjects using non-probability purposive sampling technique. Digital vernier caliper was used to measure mesiodistal and buccolingual dimensions of the central incisors, canines and the first molars in maxillary and mandibular arches of subjects with Class I and Class II malocclusions.

Results: Fluctuating asymmetry was observed in both Class I and Class II malocclusions. The gender dimorphism was observed only in Class II malocclusion group.

Conclusions: Fluctuating asymmetry was found in both Class I and Class II malocclusion. However, gender dimorphism was seen in only Class II malocclusion. Hence, assessment of fluctuating asymmetry in various malocclusion groups should be considered as a vital diagnostic parameter in orthodontic case management.
