Dental health at school age with normal children is better than that of deaf children due to limited communication due to hearing loss to receive information. Children who are basically easily saturated or bored, the strategy to overcome this problem is that a medium or method is needed in the form of a BISINDO visualization model in the form of a website-based learning video through the senses of the eye so that deaf children understand the content of the material so that changes in teething behavior are obtained. The purpose to produce alternative behavior change through the Indonesian Sign Language (BISINDO) visualization model of effective dental health to improve the brushing behavior of deaf children. The research methoad use Research and Development (R&D) and model trials using quasy experiment methods (pre and post test with control group desaign). Sampling using the lemeshow formula obtained 10 samples of children per group based on inclusion criteria. The intervention group to measure knowledge, attitudes, actions and debris indexes was then given education using the BISINDO visualization model for 21 days. The control group to measure knowledge, attitudes, actions and debris indexes was then given education using leaflet and phantom media. Results : The feasibility test of the Indonesian Sign Language visualization model (BISINDO) of websitebased dental and oral health obtained an average score of 85.6% ( very feasible). The implementation of this model is effective in increasing knowledge (p=0.003), attitude (p=0.000), action (p=0.001), and lowering the debris index score (p=0.033). Conclusion : The websitebased Indonesian Sign Language (BISINDO) visualization model of dental and oral health is feasible as an alternative to behavior change and effectively improves brushing behavior compared to the control group
