FREQUENCY OF INCLUDED CANINES, THEIR LOCATION AND DIRECTION THROUGH COMPUTERIZED TOMOGRAPHY, IN SANTIAGO, CHILE.

Abstract

Introduction: Dentomaxillofacial anomalies are frequent, among which we find the inclusion of definitive canines.The diagnosis of included canine becomes important when planning an orthodontic treatment.The objective of this study is to determine the frequency of included canines,their location and position in the arch through the analysis of computed tomography,in patients undergoing orthodontic evaluation in Santiago,Chile. Method: The database of the diagnoses of all the patients evaluated during the years 2020 and 2021 between 15 and 22 years of age was reviewed.All the pieces with the diagnosis of canines included in the study were included.Those pieces with incorrect diagnosis and those that did not have an image associated with the diagnosis or its report were excluded.The computed tomography scans of each piece were analyzed,evaluating the variables piece included,position in the vertical axis,direction and position in the mesiodistal direction. Results: 67 included canines from 63 patients were analyzed.Of these 63 patients,68.7% were women. A frequency of 0.36% of included canines was determined. 6.34% were bilateral. The piece with the highest frequency was the upper left canine. Conclusion:This is the Chilean study with the largest sample size on the subject to date.The frequency found was lower than the average of similar studies,possibly due to the age range analyzed.
