Abstract : Background: The prevalence of dental caries among pregnant women in Indonesia reaches 82.8%, caused by hormonal changes, nausea and vomiting, decreased brushing habits, and changes in salivary pH and acidity. This condition has the potential to cause pregnancy complications such as low birth weight (LBW), pre-eclampsia, miscarriage, and stunting. Effective and efficient educational media is needed, one of which is through web-based technology. Purpose: To produce a Web-Based Tris Model as a suitable and effective educational media in improving the behavior of pregnant women in preventing dental caries and reducing OHIS scores. To produce a Web-Based Tris Model as a suitable and effective educational media in improving the behavior of pregnant women in preventing dental caries and reducing OHIS scores.  Method: Type of R&D Research, Quasy experiment method Pre-Posttest group design pretest-posttest group design. Subjects consisted of 60 pregnant women divided into two groups: 30 intervention group and 30 control group. The variables studied included knowledge, attitudes, actions, and OHIS scores. using the Mann Whiteny and Wicoxon tests.  Results: The Web-based Tris model was declared feasible to use with expert validation results of 90%. The effectiveness test showed a significant increase in knowledge 22.85 to 29.15 (p=0.008), attitude 70.20 to 85.60; (p=0.030), action 68.10 to 85.50 (p=0.001), and a decrease in OHIS score 3.40 to 1.90 (p=0.000).  Conclusion: The Web-based Tris model is feasible and effective in improving behavior and reducing OHIS scores as an effort to prevent dental caries in pregnant women.
