The impact of an educational pamphlet on the awareness of parents about 4‒6-year-old children's oral habits and dentofacial discrepancies.
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.
