To investigate the prevalence and gender distributions of dental anomalies in French orthodontic patients.
A retrospective review of the dental files of orthodontic patients was conducted to investigate the frequencies of dental anomalies. Pretreatment intraoral photographs and panoramic radiographs were analyzed. The occurrence rates of various dental anomalies (as determined by the numbers, shapes, structures, exfoliations, and eruptions of teeth) were calculated as percentages and differences in gender distribution using Chi and Fisher tests.
Five hundred fifty-one patients receiving orthodontic treatment between 2003 and 2013 at a French hospital were included in the study: 45.74% of the patients (n=252) presented at least one dental anomaly. Taurodontism was the most common (15.06%), followed by ectopic eruption (11.43%). Odontoma, macrodontia, fusion, gemination, talon cusp, dentinogenesis imperfecta, regional odontodysplasia, premature tooth eruption, and premature exfoliation were not found. No statistically significant correlations were found between gender and the occurrence of dental anomalies.
French orthodontic patients exhibit a high rate of dental anomalies, indicating that dental anomalies should be carefully considered in the orodental management of French patients.
调查法国正畸患者牙齿异常的患病率及性别分布情况。
对正畸患者的牙科档案进行回顾性研究，以调查牙齿异常的发生率。分析治疗前的口腔内照片和全景X线片。计算各种牙齿异常（根据牙齿的数量、形状、结构、脱落和萌出情况确定）的发生率，并以百分比表示，同时使用卡方检验和费舍尔检验分析性别分布差异。
本研究纳入了2003年至2013年期间在一家法国医院接受正畸治疗的551例患者：45.74%的患者（n = 252）至少存在一种牙齿异常。牛牙症最为常见（15.06%），其次是异位萌出（11.43%）。未发现牙瘤、巨牙、融合牙、双生牙、尖牙、牙本质发育不全、局部牙发育异常、牙齿早萌和牙齿早脱。未发现性别与牙齿异常发生率之间存在统计学显著相关性。
法国正畸患者牙齿异常发生率较高，这表明在法国患者的口腔治疗管理中应仔细考虑牙齿异常情况。
