An impacted
tooth means that it is stuck and cannot erupt into function. And the maxillary
cuspid, namely maxillary canine, is the second most common tooth to
become impacted. Actually, there are four canines: two maxillary canines and
two mandibular canines and the canines are critical teeth in the dental arch
and play an important role to the dentofacial aesthetics and function.
Considering
the importance of canines and due to the impacted maxillary canines is a
frequently encountered clinical problem, many studies evaluated the prevalence
of impacted canines among various populations and reported vast differences in
their findings.
In this
paper, a retrospective, descriptive, cross-sectional study of 1321 digital
panoramic radiographs was conducted and the authors aimed to estimate the
prevalence of impacted maxillary canines in the general population of the city
of Nablus, Palestine. The radiographs were obtained from the records of a
private dental clinic from the year 2009 till 2016 and were examined by two
experienced examiners in order to detect impacted maxillary canines. Then
collected data were processed and analyzed by using IBM SPSS Statistics V. 22.
Besides, the authors used chi square test to reveal differences in the
distribution of impacted canines when stratified by gender, location (left or
right), and being unilateral or bilateral.
And the
findings showed that the prevalence of impacted canines among the examined
population (n = 1321) was found to be 1.8%. There was a significant association
between gender and canine impaction (P < 0.05), indicating females had
higher prevalence of canine impaction than males. The results also revealed
significantly higher unilateral canine impaction compared to bilateral
impaction. While, no significant difference in the prevalence of right or left
canine impaction was found.
In conclusion, the prevalence of impacted maxillary canines (1.8%) in
this study was within the range reported among other populations. And future
studies are needed to evaluate the etiology of teeth impaction in Palestine.
