PREVALENCE AND ASSOCIATED FACTORS FOR UNFAVORABLE CANINE IMPACTION AMONG PATIENTS REPORTING TO AN INSTITUTION- AN OPG BASED RETROSPECTIVE STUDY

Abstract

The eruption of permanent canine is a complex series of events and has the torture path of eruption before the canine reaches the occlusal plane.The aim of the study was to assess the prevalence of unfavorable canine impaction and also to assess the various factors involved in canine impaction. All case records of patients reported from July 2019 to March 2020 with malocclusion to a dental hospital were screened. The case record of 25 patients with impacted canines were selected for the study and details were recorded. Variables such as age, gender and type of malocclusion were extracted from the case records. Data was tabulated and statistically analysed using IBM SPSS version 20.0 and the results were obtained. Descriptive and chi square analysis was done to find the association among age, gender , type of malocclusion and the impacted canines.In our study, out of 25 patients, the prevalence of impacted canines among  males was 44.83% and females was 55.17%. Favorable impacted canines(62.1%) had more prevalence than unfavorable impacted canines (37.9%).On comparing the prevalence of impacted canines among different age groups, the higher prevalence was found among 21-30 years age groups (48.3%) in which unfavorable canines were 17.24%. On analysing the type of malocclusion among patients with impacted canines, type I malocclusion had higher prevalence among unfavorable impacted canines (37.93%), p>0.05.On comparing the quadrant most involved in unfavorably impacted canines, quadrant II had the highest prevalence(37.93%) , p>0.05. Within the limitation of the study favorable canine impactions were more common than unfavorable ones. Unfavorable canine impactions were more commonly associated with younger age groups, female gender and class I malocclusion. Maxillary arch and quadrant II were most commonly involved but none of the associations were statistically significant.
