中小学生口腔卫生知识水平,不仅从一个侧面反映我国人民的卫生知识水平,还直接影响着中小学生对口腔自我保健的态度行为和能力,同时对其口腔卫生状况及龋齿、牙周病的预防都有极为重要的影响。目前,美国、荷兰及香港等一些发达国家和地区均十分重视和强调要提高人群口腔卫生知识水平及口腔卫生宣教工作。这方面,我国起步较晚,有关人群口腔卫生知识水平的报道尚少。为了解其现状,我们于1989年12月中下旬,对沈阳市和平区东、北两片的中小学进行随机抽样,抽得五所小学、六所中学。选择小学五、六年级学生451人 Primary and secondary students oral health knowledge, not only reflects our people’s health knowledge level from one side, but also directly affects the primary and secondary students to oral self-care attitude and behavior, and oral hygiene, dental caries, periodontal disease prevention Have a very important influence. At present, some developed countries and regions such as the United States, the Netherlands and Hong Kong attach great importance to and emphasize the need to raise the level of oral hygiene knowledge and oral health education. In this regard, our country started relatively late, there is still little report on oral hygiene knowledge about the population. In order to understand its current situation, we conducted a random sample of primary and secondary schools in east and north two blocks of Shenyang Heping District in mid-to-late December 1989 and selected five primary schools and six secondary schools. Choose primary five, six grade 451 students
