Tooth agenesis was investigated in 101 patients with complete unilateral or bilateral cleft lip and palate presenting four third molars. The prevalence was found to be six times higher than in the control group. The most commonly missing teeth were the upper second premolars and the upper lateral incisors. With the exception of one patient, tooth agenesis in the mandible was only found in combination with congenital absence of teeth in the maxilla.
对101例单侧或双侧完全性唇腭裂且有四颗第三磨牙的患者进行了牙齿先天缺失情况的调查。结果发现其患病率比对照组高六倍。最常缺失的牙齿是上颌第二前磨牙和上颌侧切牙。除一名患者外，下颌牙齿先天缺失仅在与上颌牙齿先天性缺失同时出现时被发现。
