摘　　要：目的:了解怀化市替牙期儿童口腔健康状况和影响因素,为口腔防治工作提供依据。方法:采用分层整群抽样方法,对怀化市1543名替牙期儿童进行口腔健康检查和口腔卫生行为问卷调查。结果:替牙期儿童总患龋率为52.62%,总龋均1.64±0.66,总牙龈出血率59.43%,其中汉族儿童患龋率51.85%、龋均1.56±0.74、牙龈出血率58.77%,与少数民族儿童比较均无统计学差异(P>0.05);但总充填率6.42%,汉族儿童充填率7.58%,高于少数民族儿童(P<0.05),汉族儿童牙石检出率72.84%,低于少数民族儿童(P<0.05);在刷牙次数与使用牙膏种类等口腔卫生行为方面民族之间存在明显差异(P<0.05)。Logistic回归分析结果显示:刷牙次数少、刷牙方法不当、牙膏的选择、酸菜的偏爱是口腔牙石、牙龈出血和龋牙的危险因素。结论:怀化市替牙期儿童口腔健康状况较差,应大力加强替牙期儿童尤其少数民族口腔卫生防治工作。AIM： To investigate the oral health status and its correlating factors in children of mixed denti- tion in Huaihua city, and to provide information for the prevention and treatment of oral diseases.

The total caries rate, DMFT and the detection rate of gingival bleeding of Han childreu were 51.85% , 1.56 ± 0.74 and 58.77% respectively. There was no significant difference in caries rate, DMFT, and gingival bleeding rate among different nationalities （P 〉 0.05 ）. 7.58% of the caries teeth was filled in Han nationality, which was significantly higher than that in minority groups （P 〈 0.05 ）. The dental calculus rate of Han student was lower than that of minority groups. Nationality difference in health behavior such as frequency of tooth-brushing, choice of tooth paste was statistically significant （ P 〈 0.05 ）.
