To evaluate the prevalence of dental agenesis and its possible association with other developmental dental anomalies and systemic entities.
Descriptive transversal study, for which 1518 clinical records, of patients visited by the Odontological Service of the Primary Health Centre of Cassà de la Selva (Girona-Spain) between December 2002 and February 2006 were reviewed. The data were recorded in relation to the oral and dental anomalies and the associated systemic entities, between the ones referred as concomitant in literature.
Values of 9.48% (7.25% excluding the third molars) for dental agenesis and 0.39% for oligodontia were obtained. The presence of dental agenesis concomitant with some other forms of oral and dental anomalies was observed. Attention must be drawn to the fact that a greater number of concomitant systemic entities were observed in those patients that presented a severe phenotypical pattern of dental agenesis.
The results of the present study do not differ from the ones reported in studies of similar characteristics among Occidental and Spanish populations. The relationship observed between certain systemic entities and developmental dental anomalies suggest a possible common genetic etiology.
评估牙齿缺失的流行情况及其与其他牙齿发育异常和全身疾病的可能关联。
本研究为描述性横断面研究，共纳入了 2002 年 12 月至 2006 年 2 月期间在西班牙赫罗纳省卡萨斯德拉塞尔瓦初级卫生中心牙科服务处就诊的 1518 例患者的临床记录。记录了与口腔和牙齿异常以及文献中提到的相关全身疾病有关的数据。
得出了 9.48%（不包括第三磨牙为 7.25%）的牙齿缺失率和 0.39%的少牙症率。观察到牙齿缺失与其他一些口腔和牙齿异常形式并存。需要注意的是，在那些表现出严重牙齿缺失表型模式的患者中，观察到更多的同时存在的全身疾病。
本研究的结果与在西方和西班牙人群中进行的类似特征的研究报告的结果相似。观察到某些全身疾病与牙齿发育异常之间的关系提示可能存在共同的遗传病因。
