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.
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.
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.
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.
牙源性异常包括牙齿形态、方向或在下颌结构内空间位置的偏差。本研究调查了在沙特阿拉伯利雅得市接受治疗的正畸患者中此类牙齿畸形的发生率。此外，该研究试图辨别这些牙齿异常表现与性别和国籍之间的差异。
对2017年至2019年期间在利雅得市一家私立大学医院正畸诊所寻求治疗的正畸患者的384张全景X线片进行回顾性分析。（患者包括222名男性和162名女性）。仔细检查患者记录，以查找各种牙齿异常情况，包括但不限于弯曲牙、多生牙、先天性缺牙、阻生牙、多牙症、少牙症、牛牙症、牙齿旋转和釉质发育不全。采用卡方检验评估牙齿异常发生率与性别和国籍等变量之间的相关性。所有检验的p值小于0.05被认为具有统计学意义。
在评估的正畸患者样本中，阻生牙是最常见的牙齿异常，影响了246名患者（64.1%）。其次是31名患者（8.1%）出现多生牙，29名患者（7.6%）出现多牙症，28名患者（7.3%）出现先天性缺牙。其他较少见的牙齿不规则情况包括23名患者（6%）出现弯曲牙，12名患者（3.1%）出现釉质发育不全，12名患者（3.1%）出现牛牙症，5名患者（1.3%）出现牙齿旋转。观察到基于性别的统计学显著差异，男性（n = 154；69.4%）的阻生牙比女性（n = 92；56.8%）更常见。相反，女性（n = 24；14.8%）的多生牙比男性（n = 7；3.2%）更常见。不同国籍之间牙齿异常发生率没有明显差异。
阻生牙和多生牙是在所研究的正畸患者群体中检测到的主要牙齿异常。牙齿异常的发生率因性别而异，但不因国籍而异。这些差异可能会影响正畸治疗结果，强调了仔细检查和制定个性化正畸治疗计划的必要性。
