牙齿数目异常是口腔常见疾病,可表现为牙齿数目过多(多生牙)和牙齿数目不足(先天缺牙),2 种情况可单独发生,也可在同一个体中同时发生.Camilleri将这种既有多生牙又先天缺牙的疾病称为少牙多牙症(comcomitant hypodontia and hyperdontia,CHH),CHH是一种较为少见的疾病.目前病因不明确,患病率差异较大,男性发病率高于女性.可伴发多种综合征和其他牙齿异常等.目前关于CHH的研究多以病例报道为主,本文综合国内外的相关研究,对其病因、临床表现、诊断、影响和治疗原则作一综述.
Abnormalifies in the number of teeth is a common oral disease,which can be manifested as excessive number of teeth(supernumerary teeth)and insufficient number of teeth(congenitally missing teeth).The two conditions can occur alone or simultaneously in the same individual.Camilleri referred to this abnormality,which has both supernumerary teeth and congenital insufficient number of teeth as comcomitant hypodontia and hyperdontia(CHH).CHH is a rare disease.At present,the etiology is not clear,and the prevalence varies greatly,with the incidence in men being higher than in women.It can be associated with multiple syndromes and other dental abnormalities.Most of the research on GHH now is based on case reports.This article reviews its etiology,clinical feature,impacts,diagnosis and treatment principles by synthesizing the relevant studies at home and abroad.
