Tooth fusion is a developmental dental anomaly that may affect both the deciduous and permanent dentition. Such anomalies may cause problems such as caries, periodontal disease or even esthetic impairments, which will require intervention. In the present case, a young patient was referred to the periodontal clinic for management of bilateral mandibular fused teeth as part of the orthodontic treatment. On the lower right, the teeth involved were incompletely fused involving only the cervical region. On the lower left, the two teeth were completely fused from the crown to the apex. A surgical resection was carried out on the fused teeth on the right, while the fused teeth on the left was undisturbed. Orthodontic treatment was later carried out to align both the upper and lower arch. The patient was satisfied with treatment outcome.
牙融合是一种发育性牙体异常,可影响乳牙列和恒牙列。此类异常可能导致龋齿、牙周病甚至美观受损等问题,这就需要进行干预。在本病例中,一名年轻患者因双侧下颌融合牙的处理被转诊至牙周诊所,作为正畸治疗的一部分。在右下侧,受累牙齿为不完全融合,仅累及颈部区域。在左下侧,两颗牙齿从牙冠到根尖完全融合。对右侧的融合牙进行了手术切除,而左侧的融合牙未作处理。随后进行了正畸治疗以排齐上下牙弓。患者对治疗结果感到满意。
