The report draws on more than a decade of practice-based data collected from over 10,000 patients across 12+ countries. Featuring case studies of countries who have participated in the OHO initiative, it demonstrates how point-of-care oral health data can inform policy dialogue, research, and advocacy. The OHO initiative is aligned with the WHO Global Oral Health Action Plan, and complements national oral health surveys by providing patient-reported, practice-based data to strengthen oral health information systems.
