Mandibular Canine Transmigration: Report of Three Cases and Literature Review.

AIMS AND OBJECTIVES: Transmigration is a rare phenomenon seen almost exclusively in the mandibular canines. The aim of the present study is to review transmigration phenomenon.

MATERIALS AND METHODS: Appropriate guidelines for a systematic review were followed. The time period selected for the present systematic review was 2001-2016. The studies were selected from various electronic databases on the basis of their title, study, design, keywords, and abstracts. A total of 150 citations were searched initially, and after proper screening, 59 relevant articles were included. Additional data was obtained by searching journals and reference lists.

RESULTS: The literature search shows that transmigration is more frequent in the mandible than maxilla. The etiology of the condition is obscure; however, multiple factors have been attributed to the condition. They are more readily recognized now with the advent of panoramic radiographs. Transmigration is a rare anomaly causing varied manifestations and requires an interdisciplinary approach for management.

CONCLUSION: Early diagnosis of impacted canines is mandatory for timely treatment to ensure facial harmony and improved function.
