芜湖地区5352名中学生口腔健康状况调查分析

Survey on oral health of 5 352 middle school students in Wuhu

目的了解芜湖地区中学生口腔健康状况以便有针对性地开展牙防工作。方法采取世界卫生组织口腔健康调查方法,收集2011年12月在我院体检的5 352名中学生口腔健康状况资料,进行统计学分析。结果 5 352名中学生患龋率为38.5%,氟牙症指数为0.02,牙龈炎检出率19.1%,受检中学生的错牙合畸形患病率为92.9%。统计分析表明无论市区还是城郊女生患龋情况比男生严重,(市区χ2=64.90,P<0.01城郊χ2=16.26,P<0.01),来自城郊学生的患龋情况比来自市区的学生严重,有统计学差异(χ2=20.04,P<0.01);牙龈炎检出率市区高于城郊有统计学差异(χ2=60.01,P<0.01),男生高于女生(市区χ2=19.2,P<0.01城郊χ2=11.5,P<0.01);错牙合畸形患病率男女无统计差异(χ2=0.73,P>0.05)。结论芜湖地区中学生患龋率与全国相近,口腔卫生状况好于全国水平,错牙合畸形发病率偏高,口腔科就诊率低。

Objective To understand the oral health conditions of middle school students in Wuhu in order to explore effective measures to prevent and reduce oral diseases. Methods 5 352 students in middle schools who underwent physical examination in our hospital in December,2011 were investigated in this study according to the criterion issued by World Health Organization（WHO）. Sta- tistical analysis was done. Results Among the 5 352 middle school students in Wuhu, prevalence rate of caries and gingivitis was 38. 5% and 19.1%, index of fluorosis was 0.02, malocclusion rate was 92.9%. Statistical analysis showed that rural students had more se- rious caries than urban students （x2 = 20.04,P 〈 0.01 ） and that girls had more serious caries than boys （ urban areas x2 = 64.90, P 〈 0.01 ;rural areas X2 = 16.26,P 〈 0.01 ）. There was statistical significance. Analysis showed that urban students had more gingivitis than rural students （ X2 = 60.01, P 〈 0.01 ）, so did the boys than girls （ urban areas x2 = 19.2, P 〈 0.01 ; rural areas X2 = 11.5, P 〈 0.01 ）. There was also statistical significance. Incidence rates of malocclusions did not show significant difference between boys and girls （ X2 = 0.73, P 〉 0.05 ）. Conclusions Caries prevalence rate of middle school students in Wuhu was similar to that of the country. The oral health status was better than the national status. Malocclusion was in high incidence. Rate of visiting Department of Stomatology was low.
