目的：了解口腔健康教育对小学生口腔卫生的影响及其认知水平。研究方法：从巴西帕尔纳米林的公立学校系统中选择了247名7至15岁的学龄儿童，并随机分配到对照组（n = 115）和实验组（n = 132）。记录社会人口学数据，并进行临床检查，以建立腐朽，缺失和填充表面指数（DMFS）和DMFS指数。观察干预前后菌斑指数（VPI）和牙龈出血指数（GBI）的变化。在干预前后采用封闭式问卷调查学生的口腔健康知识。实验组参加为期4个月的口腔健康教育活动。结果如下：实验组的VPI（P = 0.014; CI 0.24-0.86）和GBI（P = 0.013; CI 0.28-0.87）在教育活动后显著降低。同样，实验组在问卷上也获得了更高的正确答案数（P < 0.0001; CI 3.73-26.81）。然而，口腔卫生指标、VPI（P = 0.311; CI 0.23-1.60）和GBI（P = 0.927; CI 0.43-2.16）与学龄儿童的信息水平无关。结论：在学校日常的情境化教育活动对口腔卫生和口腔健康的信息水平有积极的影响，虽然更知情的人并不总是实践更好的口腔卫生。
Objectives: Determine the impact of an oral health education program on oral hygiene and the awareness level of elementary schoolchildren. Methods: A total sample of 247 schoolchildren between the ages of 7 and 15 years from the public school system of Parnamirim, Brazil, were selected and randomly allocated to a control (n = 115) and experimental (n = 132) group. Sociodemographic data were recorded and a clinical examination was given to establish the decayed, missing and filled surfaces index (DMFS) and the dmfs index. The visible plaque index (VPI) and gingival bleeding index (GBI) were collected before and after the intervention. A closed-question questionnaire was applied to the schoolchildren before and after intervention to determine their knowledge of oral health. The experimental group took part in oral health education activities over a 4-month period. Results: The VPI (P = 0.014; CI 0.24-0.86) and GBI (P = 0.013; CI 0.28-0.87) of the experimental group were significantly lower after educational activities. Similarly, the experimental group also obtained a higher number of correct answers on the questionnaire (P < 0.0001; CI 3.73-26.81). However, there was no association between oral hygiene indicators, VPI (P = 0.311; CI 0.23-1.60), and GBI (P = 0.927; CI 0.43-2.16), and the information level of the schoolchildren. Conclusions: Contextualized educational activities in the school routine had positive effects on oral hygiene and the level of information about oral health, although the more informed individuals did not always practice better oral hygiene.
