Abstract：
An observational study was carried out in a teaching hospital in Saudi Arabia to determine the occurrence of dental anomalies among Arabian children. The study included children of Saudi nationality with primary teeth. The study assessed the prevalence of dental anomalies in their primary dentition. The assessment and data collection were conducted by a single examiner, utilizing clinical examination and intra-oral radiographs. A comparative analysis was conducted to examine dental anomalies in relation to gender (boys and girls) and arch type (maxillary and mandibular). In addition, the study explored the occurrence of gender-specific dental anomalies depending on arch type. The data analysis was conducted using IBM Statistics (version 21.0) with a significance level of p < 0.05. In total, there were 245 children included in the final analysis. The study population consisted of boys (66%) and girls (34%), with an average age of 4.87 ± 0.9 years. Taurodontism was the most prevalent dental abnormality, occurring in 2.8% of the individuals in the study sample. The study sample exhibited hypodontia in 2%, supernumerary teeth in 2.4%, double teeth in 2%, and microdontia in 1.2%. Talon cusp and macrodontia have a relatively low incidence of 0.4%. Boys exhibit supernumerary teeth, microdontia, macrodontia, talon cusp, and taurodontism, whereas hypodontia and double teeth were more frequent in girls.
摘要：
在沙特阿拉伯的一家教学医院进行了一项观察性研究，以确定阿拉伯儿童中牙齿异常的发生。该研究包括沙特国籍的有乳牙的儿童。该研究评估了其原发性牙列中牙齿异常的患病率。评估和数据收集由一名审查员进行，利用临床检查和口腔内X光片。进行了比较分析，以检查与性别（男孩和女孩）和牙弓类型（上颌和下颌）有关的牙齿异常。此外,该研究探讨了取决于牙弓类型的性别特异性牙齿异常的发生。使用IBMStatistics(21.0版)进行数据分析,显著性水平为p<0.05。总的来说,最终分析包括245名儿童。研究人群由男孩（66％）和女孩（34％）组成，平均年龄4.87±0.9岁。Taurodontism是最常见的牙齿异常，发生在研究样本中2.8%的个体中。研究样本表现出2%的低体血症，多余的牙齿占2.4％，2%的双齿，和microdontia在1.2%。塔龙尖牙和巨大牙体的发病率相对较低，为0.4％。男孩表现出多余的牙齿，microdontia,macrodontia,塔伦尖点,和牛磺酸症，而在女孩中，缺牙症和双牙更常见。
