摘要：

目的 了解西藏山南地区藏族高中毕业学生的口腔健康状况，为当地口腔疾病防治提供依据。方法 于2013年4月按照《第三次全国口腔健康流行病学调查方案》和世界卫生组织《口腔健康调查基本方法》的标准，对1907名西藏山南地区藏族高中毕业学生进行恒牙的龋病、牙周病、氟牙症以及口腔卫生情况检查，计算该人群的龋病指数、社区牙周指数（CPI）、简化口腔卫生指数（OHI-S）和社区氟牙症指数（CFI），并通过问卷调查其口腔卫生行为、口腔医疗服务现状和口腔保健服务要求，采用SPSS17.0统计软件对结果数据进行分析。结果 所调查的藏族高中毕业学生恒牙患龋率为39.96%，龋均为0.97；CPI中，牙龈炎检出率为59.50%，牙石检出率为62.64%；OHI-S为0.69，其中简化软垢指数（DI-S）为0.36，简化牙石指数（CI-S）为0.33；CFI为0.29，氟牙症的患病率为8.13%。问卷调查显示，学生的口腔卫生行为和口腔医疗服务现状较差，学生对口腔保健服务要求较低。结论 西藏山南地区藏族高中毕业学生的口腔患病率较高，口腔健康意识较差，应加强对该地区学生的口腔卫生宣教和对当地口腔医生的技能培训，有效防治口腔疾病。
