SYSTEMIC REVIEW: CANINE IMPACTION: PREVALENCE, CAUSES, CLASSIFICATIONS, COMPLICATIONS, AND MANAGEMENT.

The aim of this present article is to systemically review the topic of canine impaction and its components: prevalence, causes, classifications, complications, and management. The materials and methods used for this review is to search in the PubMed database using the advanced features. Keywords like canine impaction, causes, prevalence, classifications, management were used to search the database. The search aimed to identify all relevant studies written in English language. A total of 17 papers were reviewed and included in the final systemic review according to the specific keywords. Exclusion criteria were applied to exclude studies that were not PubMed indexed. With maxillary canine being the second most commonly impacted tooth after third molars, it is important to understand the causes in order to prevent it or manage it early. Therefore, further studies should be conducted as the causes are still unclear and not definitive. Moreover, the need of internationally accepted classification of canine impactions is advisable for canine impaction assessment as well as for planning for surgical operation. As for the complications, the worst complication is maxillary incisors root resorption. However, further researches using high technology (CBCT) are needed to determine a more precise percentage of root resorption cases related to maxillary canine impaction.
