Clinical examination of all the study children and self-administered questionnaire were conducted at baseline, 6th month and 12th month from implementation of the program. The children who need dental treatment were referred to health insurance clinic related to their residence area (El-Suez). The children were divided into two groups; the first group was educated by posters illustrations and the second group was educated by video cartoon film. Results: 75% of the examined children had dental caries. No statistical significant difference was found in dental caries Indices during follow up period and between poster and video groups.
