Objective

The aim of this study was to investigate the prevalence of dental anomalies in the Eastern Province of Saudi Arabia using the digital Orthopantomography (OPG).

Methods

A retrospective radiographic study was performed in which digital OPGs of 1189 subjects, ages ranging between 7 and 65 years were reviewed, and 1104 fulfilled inclusion criteria. Statistical analysis was performed. The OPGs were reviewed for congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontomas, dilacerations, taurodontism, dens in dente, gemination and fusion.

Results

OPGs of 1104 patients with mean age 35.32 ± 16.63 were included. The total prevalence of developmental anomalies in this study was 36.3% (401/1104). Male and female subjects with anomalies were 133 (33.2%) and 268 (66.8%) respectively. The prevalence of dilacerated teeth 300 (30.2%), congenitally missing teeth was 246 (24.7%), supernumerary teeth 18 (1.8%), talon cusp and taurodontism were seen in one patient each 1 (0.1%). Of these, a total of 15 (1.5%) anomalies were noted in pediatric patients.

Conclusions

Dilaceration was the most prevalent anomaly (30.2%) in the studied sample followed by congenitally missing teeth (23.4%). Talon cusp, concrescence/fusion, and taurodontism were the least prevalent anomalies.

通过数字正射影像图调查沙特阿拉伯东部省的牙齿异常患病率

客观的

这项研究的目的是使用数字正像断层扫描（OPG）来调查沙特阿拉伯东部省的牙齿异常情况。

方法

进行了一项回顾性影像学研究，其中回顾了1189位受试者，年龄在7至65岁之间的数字OPG，并且1104位受试者符合纳入标准。进行统计分析。对OPG进行了先天性缺失牙齿，撞击，异位萌发，多胎牙齿，牙周病，角膜脱落，牛角齿，牙本质窝点，成骨和融合的检查。

结果

纳入了1104名平均年龄为35.32±16.63岁的患者的OPG。在这项研究中，发育异常的总患病率为36.3％（401/1104）。患有异常的男性和女性受试者分别为133（33.2％）和268（66.8％）。每位患者中有1位（0.1％）患上锯齿状牙齿300例（30.2％），先天性缺失牙246例（24.7％），多胎牙齿18例（1.8％），骨尖和牛角齿畸形的患病率。其中，在儿科患者中总共发现了15个异常（1.5％）。

结论

在研究的样本中，最明显的异常现象是角膜剥离术（30.2％），其次是先天性牙齿缺失（23.4％）。爪尖，融合/融合和牛头牙畸形是最不常见的异常。
