Abstract
BACKGROUND: Silver diamine fluoride (SDF) has emerged as an effective, noninvasive treatment for arresting dental caries. While its use has been extensively studied in pediatric populations, there is limited evidence regarding its effectiveness in adults. MATERIALS AND METHODS: This prospective study was conducted on 100 adult patients aged 25-60 years with active caries lesions in posterior teeth. Participants were randomly divided into two groups: the experimental group received a single application of 38% SDF, while the control group received standard fluoride varnish. Caries arrest was assessed using visual-tactile examination and scored using the International Caries Detection and Assessment System criteria at baseline, 1 month, and 6 months. Patient satisfaction and side effects were also documented. Statistical analysis was performed using paired t-tests and Chi-square tests, with a significance level set at P < 0.05. RESULTS: After 6 months, 85% of caries lesions in the SDF group were arrested, compared to 45% in the fluoride varnish group (P < 0.001). Patient satisfaction scores were significantly higher in the SDF group, with a mean score of 4.7 compared to 3.5 in the control group. Minor side effects, such as temporary staining, were observed in 90% of SDF-treated teeth but were deemed acceptable by patients. CONCLUSION: The application of 38% SDF is highly effective in arresting caries in adult patients and provides a promising, minimally invasive treatment option. Although tooth staining remains a common side effect, its clinical benefits outweigh aesthetic concerns, making it a valuable tool in caries management.
