东北地区中老年人群根面龋抽样调查分析

A Sampled Investigation of the Root Caries of Adult in Northeast China

目的：了解东北地区中老年人群恒牙根龋患病状况及分布,为龋病防治策略提供依据。方法：根据全国第三次口腔健康流行病学调查的方法,对东北地区4752名35-44岁和65-74岁人群的根面龋进行了调查。以龋均和患龋率作为统计指标,采用SPSS13.0软件包进行数据的统计分析。结果：东北地区根龋患病率为12.08%,龋均为0.21。随着年龄的增高,根面龋上升显著;35-44岁人群根面患龋城乡之间无显著性差异,而65-74岁人群根面患龋城乡之间具有高度显著性差异（P〈0.01）;东北地区根面患龋男女之间具有高度显著性差异（P〈0.01）,而已充填的根面龋则男女之间无显著性差异。在上颌牙位,尖牙和磨牙根面患龋较高;在下颌牙位,磨牙患龋最高。结论：应重视东北地区中老年人根龋的防治,并采取各种保健措施,以维护和促进口腔健康。

Objective： To assess the prevalence and distribution of root caries in the adult and elderly population of Northeast China, and to provide the foundation for prevention and treatment strategies of dental caries. Methods ： A total of 4752 subjects aged 35 -44 and 65 -74 years old were selected according to the guideline for the third national oral health survey. The data obtained were collected by oral examination. Prevalence and mean DFT were calculated and SPSS13.0 package was used for the statistical analysis. Results： The prevalence of root surface caries in Northeast China was 12. 08% , with mean number of root caries of 0.21. Older adults had a higher prevalence of root caries than that of middle aged adults. There was significant difference of root caries between urban and rural area in age group of 65 -74（ P 〈 0.01 ）, but not in age group of 35 -44 years（P 〉0.05）. The significant difference on root caries was also found between male and female （ P 〈 0.01 ）, but not on filling rate （ P 〉 0.05 ）. Root Surfaces of canines and molars in the maxillary arch and molars in the mandibular arch were the most frequently affected teeth by caries. Conclusion： It should emphasized on the treatment and prevention of root caries of adult and older individuals in Northeast China.
