314 - Long-term Outcomes of SDF Treated Teeth at NYUCD’s Pediatric Clinic

Purpose: The purpose of this clinical retrospective study was to evaluate the final outcomes of teeth treated with 38% Silver Diamine Fluoride (SDF) at the New York University College of Dentistry’s Pediatric Clinic (NYUCD-PD)

Methods: Electronic Health Records of patients who received 38% SDF treatment at the NYUCD-PD from October 1, 2023 through to March 31, 2025 were evaluated. Data was extracted for age, behavior, lesion size, color, consistency, sensitivity, re-application, provider, post-operative evaluations and final outcomes including (no follow-up visits, arrested, monitor (unarrested), received additional treatment (composite/RMGI, SSC or strip crown, Hall crown, ITR), emergency visit, exfoliated, extraction, planned for definitive restoration, referred to general anesthesia). Associations were analyzed with descriptive and chi-square statistics. 

Results: 919 lesions on over 250 patients were evaluated. Application times varied from 10 seconds to 1 minute per lesion. Many initial applications were performed prior to the evaluation date range with limited reporting. In approximately 367 lesions (40%) treatment outcome is unknown, as patients did not return for follow-up visits. 174 lesions (18%) required further treatment, 55 (5.9%) were treatment planned for a restoration and 66 (7.1%) experienced an emergency or extraction of the treated tooth and 80 (8%) were referred for GA. .

Conclusion: SDF is a valuable tool for caries management on young children but repeated applications and/or further treatment may be necessary, so it should be stressed to parents the importance of routine follow-up visits for re-evaluation and prevention.
