Six young adults were found to have transmigrated mandibular canines. One patient presented with two transmigrated canines. Of the seven impacted teeth, the left mandibular canines was involved in five instances and the right two. In all patients, the primary canine was present in the dental arch. A supernumerary tooth was disclosed on the panoramic radiograph of two patients. Five patients underwent surgical removal of the transmigrated tooth from an intraoral approach. One patient experienced transient postoperative paresthesia in the zone innervated by the mental nerve. When the transmigrated canine is accessible, and especially if it is symptomatic, removal of unerupted tooth is recommended. Otherwise, it should be left alone and kept under observation.
发现6名年轻成年人有下颌犬牙异位萌出。1例患者有两颗异位萌出的犬牙。在7颗阻生牙中，左下颌犬牙受累5例，右下颌犬牙受累2例。所有患者牙弓中均存在乳牙。两名患者的全景X线片显示有一颗多生牙。5例患者经口内途径手术拔除异位萌出的牙齿。1例患者在颏神经支配区域出现短暂的术后感觉异常。当异位萌出的犬牙可以触及，尤其是有症状时，建议拔除未萌出的牙齿。否则，应任其自行生长并进行观察。
