Background. This study aimed to evaluate whether the parents' knowledge about the adverse effects of oral habits and dentoskeletal discrepancies would improve by an educational pamphlet. Methods. A parallel-group randomized clinical trial was conducted on parents in kindergartens of Shiraz, Iran, 2013. The parents completed a designed questionnaire to determine the pre-intervention score. The study group received an educational pamphlet on the oral habits and dentoskeletal discrepancies, in contrast to the control group. Three weeks later, the parents in both groups took the questionnaire again (post-intervention score). The primary outcome was a change in the parents' knowledge about oral habits and dentoskeletal discrepancies, which was measured by 13 questions of the questionnaire. Each correct answer was given a positive point and each incorrect answer a negative point. The total pre- and post-intervention scores were calculated by summing up the points and compared using Mann-Whitney U test. Results. A total of 550 subjects were assessed for eligibility and 413 were randomized. Of the study group, 203 subjects (98.56%), and of the control group, 204 parents (98.54%) completed the questionnaire for the second time. The score of the study group in the "normal occlusion" section of the questionnaire had significantly improved (P < 0.001) and in the "oral habits" section the score of both groups had improved but in the study group the improvement was significantly higher (P < 0.001). Conclusion . The educational pamphlet can be effective in increasing the level of parents' knowledge about normal occlusion and complications of oral habits.
背景。本研究旨在评估一本教育手册是否能提高家长对口腔习惯和牙颌面畸形不良影响的认识。方法。2013年，在伊朗设拉子的幼儿园对家长进行了一项平行组随机临床试验。家长们完成了一份设计好的问卷以确定干预前的得分。与对照组相比，研究组收到了一本关于口腔习惯和牙颌面畸形的教育手册。三周后，两组家长再次填写问卷（干预后得分）。主要结果是家长对口腔习惯和牙颌面畸形认识的变化，通过问卷中的13个问题来衡量。每个正确答案得一分，每个错误答案扣一分。干预前后的总得分通过计算总分得出，并使用曼-惠特尼U检验进行比较。结果。共有550名受试者接受了资格评估，413名被随机分组。研究组中有203名受试者（98.56%），对照组中有204名家长（98.54%）第二次完成了问卷。问卷“正常咬合”部分研究组的得分有显著提高（P < 0.001），“口腔习惯”部分两组得分均有提高，但研究组的提高更为显著（P < 0.001）。结论。这本教育手册在提高家长对正常咬合和口腔习惯并发症的认识水平方面可能是有效的。
