摘要: 牙齿发育异常是一种常见的发育异常, 包括牙齿萌出与脱落异常、牙齿形态异常、牙齿数目异常及牙齿结构异常。多生牙又称额外牙,属牙齿发育异常中的数目异常,是指多于正常牙类、牙数以外的牙齿。临床上可见多种形态,包括锥形、结节型、补充型和牙瘤型等。研究报道显示多生牙在恒牙列的发生率高于在乳牙列的发生率,且男性多发。多生牙会影响口腔颌面、牙弓的发育,引起牙齿阻生,牙齿迟萌,异位萌出,牙囊形成,牙根弯曲及畸形,牙列拥挤等并发症,并且与颅骨锁骨发育不全,Gardner综合征,唇腭裂等多种综合征有关。国内外众多学者都对多生牙做了相关的研究报道,本文就多生牙的病因、临床表现、诊断与治疗、相关疾病与基因做一综述。

Abstract: Hypoplasia of teeth is a human common dysplasia, including tooth eruption anomaly, number anomaly, and morphology and structure anomaly. Supernumerary teeth represent one of the most common human tooth malformations that exceed the normal number of teeth from dental formula. It can be classified as morphology, including conical, tuberculate, supplementary, and odontomas. The studies show that the prevalence of supernumerary teeth in permanent dentition is higher than that in deciduous dentition, and higher for male than female. Complications associated with supernumerary teeth include dental impaction, delayed eruption, ectopic eruption, the formation of follicular cysts, dilaceration or abnormal development of the root, overcrowding and spacing anomalies. Supernumerary teeth can be associated with cleidocranial dysplasia, Gardner syndrome, and cleft lip and palate. Substantial research related to supernumerary teeth has been conducted. This study aims to provide a review of literature on supernumerary teeth and corresponding analyses of their etiology, clinical manifestation, diagnosis, treatment, and associated disease.

Key words: Supernumerary teeth, Etiology, Clinical manifestation, Associated disease
