<![CDATA[The complexity of manual recording poses a significant barrier to maintaining standardized dental documentation. Structured, complete, and accurate documentation improves diagnostic accuracy, treatment planning, and compliance with professional standards. This study aimed to develop and evaluate the feasibility and effectiveness of the "YANSIDALU" documentation model in improving dental care standards at Dr. Cipto Mangunkusumo Hospital. A Research and Development (R&D) design was employed, combined with a posttest-only control group quasi-experimental setup. Total sampling was applied to recruit 30 dental and oral therapists at Dr. Cipto Mangunkusumo Hospital. Content validity and expert feasibility were assessed using Aiken's V index and Intraclass Correlation Coefficients (ICC). Intervention effects on therapist performance and documentation quality were evaluated using validated observational checklists and analyzed via the Mann-Whitney test. Expert validation test for the development of dental and oral health care models (mean Aiken's V 0.86; mean value 89.4%; ICC 0.710), and its application was effective on the performance of oral therapist (mean control: 82.97; intervention: 95.47; mean difference (Δ) 12.50; p-value 0.000) and quality of documentation (mean control: 77.70; intervention: 89.80; mean difference (Δ) 12.10; p-value 0.000). Development of the "YANSIDALU" documentation model is feasible and its effective application to dental and oral health care service standards.]]>
