Teeth are specialized structural components of the craniofacial skeleton. Developmental defects occur either alone or in combination with other birth defects. Macrodontia of anterior teeth may occur as an isolated condition or as a result of fusion or gemination and can occur in the primary or permanent dentition. Fusion is more commonly seen in the anterior maxillary region. This case presentation reports a case of fusion of a supplemental tooth to one in the normal series in conjunction with a talon cusp. This condition is extremely rare and has been reported at fourth occasion in the literature. The etiology, prevalence, clinical features, and management of the aforementioned anomalies have been reviewed in detail. Early diagnosis of this condition is important because it may cause clinical problems, such as esthetic concerns and tooth crowding.
牙齿是颅面骨骼的特殊结构组成部分。发育缺陷可单独出现，也可与其他出生缺陷合并出现。前牙巨牙症可作为一种孤立情况出现，也可由融合或双生导致，可发生于乳牙列或恒牙列。融合更常见于上颌前部区域。本病例报告介绍了一例额外牙与正常序列中的一颗牙融合并伴有尖牙的病例。这种情况极为罕见，文献中第四次报道。本文详细回顾了上述异常情况的病因、患病率、临床特征及治疗方法。对该疾病进行早期诊断很重要，因为它可能会引发临床问题，如美观问题和牙齿拥挤。
