Transmigration of permanent mandibular canines is a very rare phenomenon and has no definite etiology. Most of them are asymptomatic, impacted, and commonly involve the left canines. The eruption of transmigrated canines is even rarer. The purpose of this paper was to review the literature on erupted transmigrated mandibular canines and report a rare case of it in a 13-year-old girl with a transmigrated permanent right canine corresponding to the least frequent Mupparapu type 5 pattern.
恒牙下颌尖牙异位萌出是一种非常罕见的现象，病因尚不明确。大多数病例无症状、为阻生状态，且常见于左侧尖牙。异位萌出尖牙的萌出更为罕见。本文旨在回顾关于已萌出的异位下颌尖牙的文献，并报告一例罕见病例，该病例为一名13岁女孩，其右侧恒牙尖牙异位萌出，符合最不常见的Mupparapu 5型模式。
