【目的】分析新疆地区唇腭裂患者牙齿数目、形态和萌出异常,协助唇腭裂患者序列治疗。【方法】分析80例唇腭裂患者的全口曲面断层片和全口牙列模型,进行分类整理及统计学分析。【结果】单侧唇腭裂患者中裂隙侧恒侧切牙先天缺失的发生率为57.8%、健康侧为17.8%;裂隙侧上颌中切牙扭转的发生率为75.6%、健康侧为8.9%;均有统计学意义(P<0.05)。双侧唇腭裂和单纯腭裂患者中恒侧切牙先天缺失的发生率分别为60.0%、15.0%;多生牙的发生率分别为26.7%、5.0%;上颌中切牙扭转率分别为73.3%、20.0%。【结论】唇腭裂患者牙齿数目、形态、萌出异常比较严重,使唇腭裂患者的诊断和治疗更加复杂化。
【Objective】 To analyze the number, morphology and eruption of teeth in patients with cleft lip and palate in Xinjiang and assist in the treatment of cleft lip and palate patients. 【Methods】 Totally 80 patients with cleft lip and palate were analyzed with full-faceted section and complete dentition. The classification and statistics were analyzed. 【Results】 The incidence of congenital incisors was 57.8% in cleft side and 17.8% in unilateral cleft palate. The incidence of torsion of maxillary central incisor in cleft side was 75.6% and that in healthy side was 8.9% There was statistical significance (P <0.05). The incidences of congenital incisors were 60.0% and 15.0% in patients with bilateral cleft lip and palate and pure cleft palate, respectively. The prevalence of multiple births was 26.7% and 5.0% respectively. The torsion rates of maxillary incisors were 73.3% 20.0%. 【Conclusion】 The number, shape and eruption of teeth in patients with cleft lip and palate are more serious, complicating the diagnosis and treatment of patients with cleft lip and palate.
