The aim of this retrospective study was to describe the distribution of the non-syndromal supernumerary teeth (NSST) in a population of patients who attended the clinics of Riyadh Colleges of Dentistry and Pharmacy (RCsDP), Riyadh, Saudi Arabia.
The study reviewed 1521 panoramic radiographs of Saudi and non-Saudi subjects who attended RCsDP clinic from November 2009 to November 2010. The data were analyzed using the Statistical Package for Social Sciences, utilizing Chi-square.
Eighteen (1.2%) patients were found to have NSST, comprising twelve males (66.7%), and six females (33.3%). The most common supernumerary teeth (ST) were the pre-molars six cases (33.3%), followed by the mesiodens, five cases (27.8%). The canines and distomolars three cases (16.6%) each respectively, while the least were the lateral incisors and paramolars of the two cases (11.1%) each.
Consanguinity appeared to have a role in the development of hyperdontia in Saudi population because 13 cases (72.2%) out of 18 cases had consanguineous parents, while all patients having consanguineous parents had eumorphic ST.
这项回顾性研究的目的是描述在沙特阿拉伯利雅得牙科与药学院（RCsDP）诊所就诊的患者群体中非综合征性多生牙（NSST）的分布情况。
该研究回顾了2009年11月至2010年11月期间在RCsDP诊所就诊的沙特和非沙特受试者的1521张全景X线片。使用社会科学统计软件包进行数据分析，并采用卡方检验。
发现18例（1.2%）患者有多生牙，其中男性12例（66.7%），女性6例（33.3%）。最常见的多生牙是前磨牙，共6例（33.3%），其次是正中多生牙，共5例（27.8%）。尖牙和远中磨牙各有3例（16.6%），而最少见的是侧切牙和副磨牙，各有2例（11.1%）。
近亲结婚似乎在沙特人群多生牙的发生中起作用，因为18例中有13例（72.2%）患者的父母为近亲，而所有有近亲父母的患者的多生牙形态正常。
