Mandibular Canine Transmigration: Report of Three Cases and Literature Review

Transmigration is a rare phenomenon seen almost exclusively in the mandibular canines. The aim of the present study is to review transmigration phenomenon. 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. 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. Early diagnosis of impacted canines is mandatory for timely treatment to ensure facial harmony and improved function.
