单侧完全性唇腭裂男性患者的牙齿发育状况

Dental development of male patients with complete unilateral cleft lip and palate

目的评估单侧完全性唇腭裂（UCLP）男性患者的牙齿发育状况。方法将40例6-14岁的UCLP男性患者作为唇腭裂组,另选取年龄、种族与唇腭裂组相匹配的40例非唇腭裂男性作为对照组,拍摄全颌曲面断层片。参照Demirjian法,通过所拍摄的全颌曲面断层片评估牙齿成熟指数。结果在唇腭裂组下颌牙齿中,裂隙侧牙齿成熟指数比非裂隙侧低（P〈0.01）。与对照组相比,唇腭裂组的下颌牙齿与非裂隙侧上颌牙齿的成熟指数低（P〈0.05）。结论与非唇腭裂男性相比,UCLP男性患者牙齿发育迟缓。

Objective To evaluate the dental development of male patients with unilateral cleft lip and palate （UCLP）. Methods A total of 40 male UCLP patients aged 6 to 14 years were selected as cleft lip and palate group （ CLP group）. Another 40 age- and race-matched non-CLP male individuals were chosen as control group. Panoramic radiographs were taken for the patients. Their dental maturity index was evaluated with the panoramic radiographs, according to Demirjian,s method. Results In the mandibular teeth of the CLP group, the dental maturity index of the cleft side was lower than that of the non-cleft side （ P 〈0.01 ）. Compared with the control group, the CLP group had lower dental maturity index in the mandibular teeth and the maxillary teeth of the non-cleft side （ P 〈 0.05 ）. Conclusion Compared with non-CLP male individuals, male patients with UCLP have a delay in the dental development.
