A study of the knowledge about dental health and diseases of youths in their late teens has been conducted. A 10-class questionnaire relating to dental caries and gingivitis/periodontitis was answered by three test groups (A, B, C) totalling seventy-eight 19-year-olds who, during a 3-year period, had undergone professional prophylaxis at different intervals. Nineteen young people of the same age without organized preventive measures since their last attendance at the public dental service constituted a control group (D). The test groups were found to have a significantly better knowledge of factors relating to gingivitis/periodontitis than the control group. In questions relating to caries there were no differences among the groups. Higher points were scored in knowledge of therapy and prevention than of the causes and symptoms of the dental diseases. Several regularly repeated sessions for professional prophylaxis did not lead to better knowledge than only a few. No consistent correlation was found for any of the groups between knowledge and both quantitative tooth cleaning, i.e. type and frequency of use of oral hygiene aids, and qualitative tooth cleaning, expressed as the occurrence of plaque and gingivitis. Nor were significant differences found in these respects between individuals with and without a caries increment during the observation period regardless of grouping.
一项针对接近二十岁青少年的牙齿健康与疾病知识的研究已经展开。三个测试组（A组、B组、C组）共七十八名19岁的青少年回答了一份与龋齿和牙龈炎/牙周炎相关的十类问卷，这些青少年在三年期间接受了不同间隔的专业预防治疗。自上次就诊于公共牙科服务机构后未采取有组织预防措施的十九名同龄年轻人构成了一个对照组（D组）。结果发现，测试组在与牙龈炎/牙周炎相关因素方面的知识明显优于对照组。在与龋齿相关的问题上，各组之间没有差异。在治疗和预防知识方面的得分高于牙齿疾病的病因和症状方面的得分。多次定期重复进行专业预防治疗并没有比仅进行几次带来更好的知识掌握情况。在任何一组中，知识与定量刷牙（即口腔卫生辅助工具的使用类型和频率）以及定性刷牙（以牙菌斑和牙龈炎的发生情况表示）之间均未发现一致的相关性。在观察期内，无论分组情况如何，有龋齿增量和无龋齿增量的个体在这些方面也未发现显著差异。
