摘要
目的了解东北地区第一恒磨牙患龋状况,为龋病防治策略提供依据。方法根据第三次全国口腔健康流行病学抽样调查方案,对东北地区9394名5、12、35～44和65～74岁人群的第一恒磨牙龋病进行调查,采用SPSS13.0软件对数据进行统计分析,以患龋率和龋均作为统计指标。结果东北地区第一恒磨牙冠龋和根龋患病率分别为26.86%和3.81%,龋均分别为0.41和0.04,各省之间的患龋情况存在差异。冠龋主要发生于下颌,女性高于男性(P<0.01),而根龋男女之间无统计学差异(P>0.05)。辽宁省和黑龙江省第一恒磨牙冠龋城市高于农村(P<0.01),但吉林省冠龋城市与农村无统计学差异(P>0.05),根龋则各省城乡之间均无统计学差异(P>0.05)。结论东北地区第一恒磨牙患龋较严重,应引起口腔医务工作者对其防治的重视。
Objective To survey the tooth decay of the first molars among the people in area of northeast China in order to provide the foundation for prevention and treatment strategies of caries. Methods According to the third national oral health investigation of epidemiology, the dental caries of first permanent molars were examined among 9 394 people aged 5, 12, 35-44 and 65-74 in northeast China. The data were analyzed by SPSS 13.0 statistical software. Dental caries prevalence rate and DMFT（dmft） of first permanent molar were calculated. Results The prevalence of crown and root dental caries in northeast China were 26.86% and 3.81% respectively, mean DMFT（dmft） of crown and root dental caries were 0.41 and 0.04 respectively. Then were significant differences of dental caries among provinces in northeast China. Mandibular first molar suffered from dental caries easily. The prevalence of caries of female was higher than that of male （P〈0.01）, but there was not significant difference of prevalence of root caries between two sexes （P〉0.05）. Except Jilin province, there were significant differences of prevalence of crown caries between city and rural area in Liaoning and Heilongjiang provinces （P〈0.01）. It was no significant difference of prevalence and mean DMFT（dmft） of root caries between city and rural area in each province （P〉0.05）. Conclusion The prevalence of dental caries of the first molar among the people in northeast China is high. The dental caries prevention and cure of first permanent molar should be emphasized in oral health field.
