摘要/Abstract

摘要： 多生牙是指牙弓上除20颗乳牙以及32颗恒牙以外的牙或者具有牙结构的物质。在临床中,多生牙常常会引起多种并发症,包括牙列不齐、恒牙阻生、邻牙牙根吸收、囊肿形成等。流行病学研究表明,上颌前牙区多生牙发病率最高,在恒牙列发病率为1.5%~3.5%,乳牙列为0.3%~0.8%,拔除多生牙对预防并发症具有积级意义,然而目前临床研究对于多生牙的拔除时机仍然存在较大争议。本文主要针对上颌前牙区多生牙的临床特征及国内外治疗时机研究进展进行回顾。

关键词: 多生牙, 牙拔除, 治疗时机

Abstract: The definition of supernumarary teeth is that teeth come from dental sac in excess of the normal number. Mesiodens are the most common supernumerary teeth, occurring in 0.3%-0.8% in deciduous dentition and 1.5%-3.5% in permanent dentition. Supernumerary teeth always cause complications such as dental impaction, overcrowding, root dilacerations, or the formation of follicular cysts. The aim of this paper is to review the prevalence, etiology, diagnosis, treatment, and complications of Mesiodens.

Key words: supernumerary tooth, tooth extraction, timing
