Topography of Maxillary Impacted Canines in Comparison to their normal Counterpart through CBCT

Abstract

Introduction: Developmentally Maxillary cuspid is the most wavering tooth in a dental arch. No other tooth in dental arch travels the tortuous pathway from initiation of formation to fully emergence into oral cavity. Maxillary canine impaction is often seen as a clinically presenting problem in dentistry. Unilateral impacted canine is prevalent among 1-3% of the general population.

Objective: The goal of the study was to measure and compare the mesio-distal and labio-lingual dimensions, anatomical crown and root height of a unilateral maxillary impacted canine with its normal counterpart through cone-beam computer tomography (CBCT).

Methodology: CBCT images of 38 patients including 18 males and 20 females having unilateral impacted canine were acquired from multiple teaching hospitals of Rawalpindi and Islamabad. Mesio-distal, labio-lingual, anatomical Crown and Root height were measured of the impacted and erupted canines with measuring tool in Planmeca Romexis® Viewer Launcher.

Results: Mean anatomical Crown and Root height were higher in non-impacted side, however, statistically the difference was non-significant (p=0.737 and 0.450 respectively). Mean mesio-distal width and Labio-lingual measurement were lower in non-impacted side, however, the statistically non-significant difference was found (p=0.255 and 0.853 respectively).

Conclusion: Statistically no significant difference between the mesio-distal, labio-lingual, anatomical Crown and Root height of the impacted canine with their normal counter-part were reported. However, Crown and Root height were higher in non-impacted side while mesio-distal width and labio-lingual measurement were lower in non-impacted side.
