Supernumerary teeth is a term that describes the presence of additional teeth beyond the normal complement. Supernumerary teeth have been reported in both the primary and permanent dentition, although they are more prevalent in the permanent dentition. Bilateral symmetrical impacted fourth molars are exceedingly uncommon, especially in combination with other supernumerary teeth. This article describes an unusual case of hyperdontia and highlights the importance of correct diagnosis and treatment.
多生牙是一个描述超出正常牙数额外存在牙齿的术语。多生牙在乳牙列和恒牙列中均有报道，尽管在恒牙列中更为常见。双侧对称埋伏的第四磨牙极为罕见，尤其是与其他多生牙同时出现时。本文描述了一例罕见的多生牙病例，并强调了正确诊断和治疗的重要性。
