Effectiveness of Silver Diamine Fluoride Application at Various Frequencies for Dental Caries Cessation among Preschool Children in India: Randomized Controlled Trial

More frequent SDF applications (four times per year) were significantly more effective in halting caries progression compared to biannual or annual applications, particularly evident in tribal children; a high-risk population with limited access to dental care. The study supports the use of SDF as a noninvasive, cost-effective preventive treatment for young children, especially in resource-limited settings, and emphasizes the need for frequent SDF applications in community-based oral health programs with limited dental care access.
