Prevalence rate of Buccally Displaced Canine and Its Dentoskeletal 3-Dimesional relation in Indian Population
Journal Title: International Journal of Medical and Health Sciences - Year 2015, Vol 4, Issue 3
Abstract
Objective: The aim of the study was to analyse the prevalence and distribution of buccally displaced canines (BDCs) in subjects scheduled for orthodontic treatment and to investigate the association between BDC and sagittal, vertical, and transverse dentoskeletal relationships. Material and methods: A study sample of 748 subjects was examined, and it was divided randomly into two groups. A first group of 189 subjects served as control group: the ‘reference’ prevalence rates for the examined parameters were calculated in this group. The remaining 748 subjects comprised the sample from which the experimental BDC group was derived. Presence of unilateral or bilateral maxillary BDC, ANB, and SN-GoGn angles for sagittal and vertical skeletal relationships, intercanine and intermolar distances at the maxillary arch was recorded for each subject. The statistical significance of differences between the BDC and the control groups in transverse relations at the upper arch was tested by means of independent sample t-tests. Chi-square tests were performed to compare the prevalence rates of BDC and also sagittal and vertical skeletal features in the two groups. Results: The prevalence rate of BDC was 3.06 per cent with a male-to-female ratio of 1:1. BDC subjects exhibited a significant association with hyperdivergent skeletal relationships (21.8%), reduced maxillary intercanine width, and crowding in the upper arch. Conclusion: The presence of specific dentoskeletal characteristics (i.e. hyperdivergent growth, reduced transverse inter-canine width and crowding) can be considered as a risk indicator for developing a buccal displacement of upper permanent canines.
