Abstract

Aim. The purpose of this study was to investigate the prevalence of transmigrated canines in a north Indian population and association with gender, side, associated pathologies, and dental anomalies. Subjects and methods. The prospective study consisted of panoramic radiographs of 3000 patients from two dental colleges in north India. The panoramic radiographs were screened for radiographically identified position of the transmigrated tooth, retained canine, and other coexisting dental anomalies. Results. The overall prevalence of transmigrated canines (15 mandibular and 5 maxillary) was 0.66%. The prevalence of mandibular transmigrated canine was 0.5% and maxillary transmigrated canine was 0.16%. All the transmigrated canines were unilateral. The age range was 15–53 years (average age 24.1 years) and there were 12 males (60%) and 8 females (40%). Type 1 mandibular canine transmigration was the commonest type found in our study (10 cases), followed by types 2 and 4 (2 cases each) and 1 case of type 5 transmigration. Conclusion. The prevalence of transmigrated canines in the north Indian population was 0.66% and no gender predilection was evident. The transmigrated canines have a low complication rate (10.0%) and no correlation with other dental anomalies was found. Type 3 canine is the rarest form of mandibular canine transmigration.

Highlights

The preeruptive migration of a tooth across the midline is termed as “transmigration.” Initially, the term transmigration was used only if the entire length of the impacted canine had migrated and crossed the midline of the mandible [1]
We determine the prevalence of transmigrant maxillary and mandibular canines in a north Indian population and describe the clinical and radiographic features of patients with transmigrant impacted canines
Leftside predominance was observed for mandibular canine transmigration with 11 patients observing left mandibular canine migrating towards right side and four cases migrating from the right side towards left side (P < 0.5)

Summary

Introduction

The preeruptive migration of a tooth across the midline is termed as “transmigration.” Initially, the term transmigration was used only if the entire length of the impacted canine had migrated and crossed the midline of the mandible [1]. Javid modified the definition by suggesting that one half or more of the length of the tooth was required to cross the midline in order to be considered as transmigration [2, 3]. The prevalence of transmigration in different populations and ethnic groups was the subject of several studies and was reported to be between 0.1 and 0.34% [5,6,7]. To the best of our knowledge, the present study is the first to report the prevalence of both transmigrated maxillary and mandibular canine in India. We determine the prevalence of transmigrant maxillary and mandibular canines in a north Indian population and describe the clinical and radiographic features of patients with transmigrant impacted canines
