评估深圳市35~44岁人群口腔健康行为，为深圳市口腔卫生保健工作提供信息支持。

采用多阶段随机抽样方法，抽取深圳市35~44岁常住居民共1230人，按照《第三次全国口腔健康流行病学问卷调查方案》设计口腔健康调查问卷，就行为生活方式、口腔卫生服务的使用及获取口腔保健知识的来源及途径等进行调查分析，回收有效问卷1224份。

深圳市35~44岁人群中，91.7%每天刷牙，55.6%每天刷牙2次及2次以上；72.1%的人使用含氟牙膏刷牙，牙线使用率极低；近1年内口腔科就诊率15.9%，90%以上是因为急、慢性牙疼和其他口腔问题，进行定期口腔检查的人口比率极少。电视/广播仍为获取口腔卫生知识的最主要途径，而其它途径少。
