Abstract

Objective: The objective of this study is to assess the prevalence and pattern of maxillary canine impaction (MCI) in the population of Saudi Arabia according to the Yamamoto classification.

Materials and methods: A total of 5000 orthopantomogram (OPG) images of 2500 males and 2500 females in the age group of 14-40 years who attended the orthodontic clinic in Najran city from a period between January 2016 to February 2019 were evaluated for the presence of maxillary canine impaction. The anatomical position of each maxillary canine impaction was matched to the seven subtypes mentioned in the Yamamoto's classification.

Results: The prevalence of MCI was found to be 3.46% in Najran(Saudi Arabia) population. Type I (46%) accounted for the highest prevalence followed by Type II (37%) and Type VI (8%). Type III, V and VII was found to be 3% equally and no case was of Type IV was found in the studied population. MCI was more common in females and left side compared to males and right side respectively.

Conclusion: The prevalence of maxillary canine impaction was found to be 3.46% in Najran. Type I pattern of maxillary canine impaction was commonest followed by Type II, VI, III, V and VII.
