Background and Objectives: Oral and dental diseases are one of the most important problems of today’s society. To reduce the cost and outcomes of these diseases, prevention and control of plaque is of high importance. This study aimed to determine the effectiveness of conventional and video education methods on children’s dental health. Methods: This interventional study was performed on 66 male elementary school students in Qomrood village in 2018. The students were randomly assigned to one of the two groups of conventional and video education methods. The amount of plaque index and bleeding on probing (BOP), were recorded in checklist before and after 2 weeks of education. The data were analyzed by independent and paired t-tests. Results: In the conventional group, the mean plaque index before the intervention was reported to be 58.66±16.95 and after intervention 18.60±10.76; also, the mean BOP was 1.28±1.97 before intervention and 0.16±0.46 after intervention. In video education group, the mean plaque index before the intervention was 53.84±14.08 and after intervention 19.29±10.91, and the mean BOP was obtained 1.68±3.71 before intervention and 0.31±0.76 after intervention. The result of paired samples t-test showed the changes of both group were significant, but the result of independent samples t-test, there was no significant difference between the changes of the two groups. Conclusion: According to the results of this research, both methods of conventional education and video education have significant effect on reduction of plaque index and BOP, but, there is no significant difference between the effectiveness of these methods.
