ABSTRACT
Introduction:
Although prevalence of impacted canines has been analyzed in prior studies,
there is a lack of evidence about the
prevalence of impacted canines in the Malaysian population to support
such practices. Understanding
the prevalence of impacted canines will
enhance
awareness, knowledge, and understanding of the importance of obtaining
preventive and interventional treatment.
The research aims to establish the impacted canine prevalence in orthodontic
patients using
cone beam computed tomography (CBCT).
Materials and
Methods:
An examination of clinical records of 175 patients with canine impaction from
January 1st, 2010, to November 30th, 2020
who had CBCT scans and visited dental clinics for orthodontic treatment was done
to determine their prevalence.
Descriptive statistics and
Chi-square test analysis were carried out to evaluate the results.
Results:
The results suggested that the impacted canine prevalence was 17.5 %, with a
female preponderance. Impacted canines occurred most frequently in Class I
malocclusion subjects. In addition, canine impaction is more frequent on the
left side than on the right. Unilateral impaction dominated bilateral impaction.
Palatal impaction was more prevalent than buccal impaction, while maxillary
canine impaction was more common than mandibular impaction.
Conclusions:
This study’s prevalence was higher than previously reported
among
other populations.
The demography and gender have an effect on the incidence of impacted canines.
These
three-dimensional (3D)
findings may provide
clinical reference data
for delivering information and education on impacted canines assessment and
treatment.
