To examine the prevalence of different types of dental anomalies in children with nonsyndromic cleft lip, unilateral cleft lip-palate, and bilateral cleft lip-palate.
A sample of 90 patients (aged 4-20 years) affected by isolated cleft lip, unilateral and bilateral cleft lip and palate was examined. Cleft patients were classified into one of three groups according to cleft type: (1) Unilateral Cleft Lip-Palate, (2) Bilateral Cleft Lip-Palate, and (3) Cleft Lip. Intraoral exams, panoramic radiographs and dental casts, were used to analyse the prevalence of the various dental anomalies included in this study.
There were no statistically significant differences between patients with cleft lip, unilateral cleft lip and palate and bilateral cleft lip and palate. The congenital absence of the cleft-side lateral incisor was observed in 40% of the sample, and a total of 30% patients showed supernumerary teeth at the incisors region. Second premolar agenesis was found in 4.4% of patients, whereas in 18.9% of the sample there was an ectopic dental eruption. Lateral or central incisors rotation was noted in 31.1% of the sample, while shape anomaly, lateral incisor microdontia, and enamel hypoplasia were detected respectively in 25.6%, 5.6% and 18.9% of cleft patients.
High prevalence of different dental anomalies in children with cleft lip and unilateral and bilateral cleft lip and palate has been confirmed. This study, in particular, shows the presence of ectopic and rotated teeth in the cleft area.
研究非综合征性唇裂、单侧唇腭裂和双侧唇腭裂患儿中不同类型牙齿异常的患病率。
对90例（年龄4 - 20岁）单纯唇裂、单侧唇腭裂和双侧唇腭裂患者进行检查。根据腭裂类型将腭裂患者分为三组之一：（1）单侧唇腭裂，（2）双侧唇腭裂，（3）唇裂。采用口腔检查、全景X线片和牙模分析本研究中各种牙齿异常的患病率。
唇裂、单侧唇腭裂和双侧唇腭裂患者之间无统计学显著差异。40%的样本中观察到腭裂侧侧切牙先天性缺失，共有30%的患者在前牙区出现多生牙。4.4%的患者发现第二前磨牙缺失，而18.9%的样本存在牙齿异位萌出。31.1%的样本中观察到侧切牙或中切牙扭转，唇裂患者中分别有25.6%、5.6%和18.9%检测到形态异常、侧切牙过小和釉质发育不全。
已证实唇裂、单侧唇腭裂和双侧唇腭裂患儿中不同牙齿异常的患病率较高。本研究尤其显示了腭裂区域存在异位牙和扭转牙。
