Individuals with cleft lip and palate present significantly more dental anomalies, even outside the cleft area, than do individuals without clefts. Our aim was to evaluate the prevalence of tooth agenesis and patterns of hypodontia in a large sample of patients with complete bilateral cleft lip and palate (BCLP). Serial panoramic radiographs (the first radiograph was taken at 10.5-13.5 yr of age) of 240 patients with BCLP (172 male patients, 68 female patients) were examined. Third molars were not included in the evaluation. Agenesis of at least one tooth was present in 59.8% of patients. Upper laterals and upper and lower second premolars were missing most frequently. Using the tooth agenesis code (TAC), 52 different agenesis patterns were identified, of which simultaneous agenesis of 12, 22, 15, 25, 35, and 45 was the most frequent pattern. Nine of the 240 patients showed combined BCLP and oligodontia.
与非腭裂患者相比，唇腭裂患者出现明显更多的牙齿异常，即使在腭裂区域之外。我们的目的是评估大量完全性双侧唇腭裂（BCLP）患者中牙齿缺失和缺牙模式的患病率。对240例BCLP患者（172例男性患者，68例女性患者）的系列全景X线片（第一张X线片拍摄于10.5 - 13.5岁）进行了检查。评估中未包括第三磨牙。59.8%的患者存在至少一颗牙齿缺失。上颌侧切牙以及上颌和下颌第二前磨牙缺失最为常见。使用牙齿缺失编码（TAC），识别出52种不同的缺失模式，其中12、22、15、25、35和45号牙同时缺失是最常见的模式。240例患者中有9例同时患有BCLP和少牙症。
