Abstract：
BACKGROUND: Odontogenic anomalies encompass deviations in dental morphology, orientation, or spatial positioning within the mandibular structures. This study probed the frequency of such dental malformations among orthodontic patients receiving treatment in Riyadh City, Saudi Arabia. Furthermore, the study sought to discern variations in the manifestation of these dental anomalies related to gender and nationality.
METHODS: A retrospective analysis was conducted on 384 panoramic radiographs belonging to orthodontic patients (comprising 222 males and 162 females) who sought treatment at orthodontic clinics of a privately owned university hospital in Riyadh City between 2017 and 2019. The patient records were scrutinized for various dental abnormalities, including but not limited to dilacerated teeth, supernumerary teeth, congenital absence of teeth, impactions, hyperdontia, hypodontia, taurodontism, tooth rotation, and amelogenesis imperfecta. The Chi-square test was employed to assess the correlation between the prevalence of dental anomalies and variables such as gender and nationality. A p-value of less than 0.05 was deemed statistically significant for all tests.
RESULTS: Among the assessed sample size of orthodontic patients, dental impactions emerged as the most prevalent dental anomaly, affecting 246 patients (64.1%). This was followed by the occurrence of supernumerary teeth in 31 patients (8.1%), hyperdontia in 29 patients (7.6%), and congenital absence of teeth in 28 patients (7.3%). Other less frequently observed dental irregularities included dilacerated teeth in 23 patients (6%), amelogenesis imperfecta in 12 patients (3.1%), taurodontism in 12 patients (3.1%), and tooth rotations in five patients (1.3%). A statistically significant gender-based disparity was observed, with dental impactions being more prevalent among males (n=154; 69.4%) than females (n=92; 56.8%). Conversely, supernumerary teeth were more prevalent among females (n=24; 14.8%) than males (n=7; 3.2%). No significant variation in the prevalence of dental anomalies was discernible across different nationalities.
CONCLUSIONS: Impactions and the presence of supernumerary teeth were the predominant dental anomalies detected among the studied orthodontic patient population. The prevalence of dental anomalies exhibited discernible variations based on gender but not nationality. These disparities could potentially influence orthodontic outcomes, underscoring the necessity for meticulous examination and tailored orthodontic treatment planning.

摘要：
背景：牙源性异常包括牙齿形态的偏差，定位,或下颌结构内的空间定位。这项研究探讨了在利雅得市接受治疗的正畸患者中此类牙齿畸形的频率，沙特阿拉伯。此外，这项研究试图辨别这些与性别和国籍有关的牙齿异常表现的差异。
方法：对2017年至2019年间在利雅得市一家私立大学医院的正畸诊所寻求治疗的384名正畸患者（包括222名男性和162名女性）进行了回顾性分析。检查病人的记录是否有各种牙齿异常，包括但不限于撕裂的牙齿，多余的牙齿，先天性牙齿缺失，撞击，Hyperdontia,缺省症,牛磺酸症,齿旋转,和牙釉质发育不全。采用卡方检验评估牙齿异常的患病率与性别和国籍等变量之间的相关性。对于所有测试,小于0.05的p值被认为是统计学上显著的。
结果：在评估的正畸患者样本量中，牙齿嵌塞是最常见的牙齿异常，影响246例患者（64.1%）。其次是31例(8.1%)出现多生牙,29例患者（7.6％），28例（7.3％）先天性牙齿缺失。其他较不常见的牙齿不规则包括23例患者（6％）的撕裂牙齿，12例患者（3.1％），12例患者（3.1％），5例患者(1.3%)的牙齿旋转。观察到统计学上显著的基于性别的差异，男性（n=154；69.4％）比女性（n=92；56.8％）更普遍。相反，多余的牙齿在女性中（n=24；14.8％）比男性（n=7；3.2％）更普遍。在不同民族之间，牙齿异常的患病率没有显着差异。
结论：在所研究的正畸患者人群中检测到的主要牙齿异常是撞击和多余牙齿的存在。牙齿异常的患病率根据性别而不是国籍表现出明显的差异。这些差异可能会影响正畸结果，强调需要进行细致的检查和量身定制的正畸治疗计划。
