【摘要】 [目的]了解厦门地区聋哑学生错畸形的患病情况及相关因素。[方法]对厦门聋哑学校270名学生与正常学生对照组同时进行错情况调查及分析。[结果]聋哑组错畸形患病率60.0％(其中男性占39.3％,女性占20.7％);恒牙期错殆率42.2％,替牙期错率17.8％,舌系带过短率8.2％,唇系带异常率6.7％。健康组错畸形患病率62.3％,舌系带过短率6.6％,唇系带异常率4.8％。[结论]两组错畸形、舌系带过短、唇系带异常率差异均无显著性(P>0.05)。唇舌系带过短、错畸形与聋哑残疾障碍无相关。聋哑群体的错畸形,应同样受到人们的重视和关注。更多还原

【Abstract】 [Objective] To investigate the prevalence rate and the related factors of the deaf-mute student’s malocclusion in Xiamen, China. [Method] To investigate and analyze the malocclusion of the 270 deaf-mute students and the normal students. [Result] The prevalence rate of malocclusion was 60. 0% in the deaf-mute students (39. 3% for male and 20. 7% for female). The periods of permanent tooth was 42. 2% and the periods of mixed tooth was 17.8%; The prevalence rate of ankyloglossia was 8.2%; the rate of short labial frenum was 6.7%. The rate of malocclusion in normal students was 62. 3%, ankyloglossia 6. 6% , and abnormity labial frenum 4. 8%. [Conclusions] The prevalence rates of the malocclusion, ankylogolossia and the abnormity labial frenum are no significant difference between two groups (P>0. 05) and they are not related with the deaf-muteness. It is suggested that the malocclusion condition of the deaf-mute students should be concerned the same as the normal group.更多还原
