目的掌握南京市学生口腔疾病动态状况，为制定学生口腔疾病防治规划，监测与评价防治效果提供依据。方法于1985年～195年采用世界卫生组织（WHO）推荐、卫生部制定的调查标准开展了学生龋病、牙周疾病流行病学调查，对统计结果进行回顾性分析。结果3、6、9岁三个年龄组乳牙平均患龋率1985年为61．54％到1995年增高至66．90％，其中6岁组患龋率1995年为89．25％，dmft为5．74±3．60。7、9、12、15、17岁五个年龄组恒牙平均患龋率1985年为31．90％，到1989年增高至37．28％，1995年降至30．74％，其中12岁组患龋率1995为27．25％，DMFT为0．57±1．01。五个年龄组平均牙龈炎患病率、牙结石检出率，分别从1985年58．48％、37．04％到1992年升至68．21％、43．30％，1995年回落到53．80％、33．49％。结论建议在学校、幼儿园推广多种局部用氟和窝沟封闭防龋术，大力开展口腔健康教育及早期检查、早期治疗。
