321 - Silver Diamine Fluoride Effectiveness by Tooth Location at 12-18 Month Recall

Purpose: The purpose of the study was to determine if tooth location predicts arrest of carious lesions treated with Silver Diamine Fluoride (SDF) when evaluated at 12-18 month recall.

Methods: This was a retrospective chart review of patients under the age of 9 years who attended the NYU Dentistry post-graduate clinic and received SDF on at least one asymptomatic cavitated lesion during the time period of 2015 to 2021. Collected data included exam age, number of decayed, missing, and filled tooth surfaces (DMFS) at initial exam and 12-18 month recall, and the number and location of teeth and surfaces treated by SDF.

Results: Overall caries arrestation rate of SDF treated surfaces at 12-18M RC was 36%, including extracted and restored surfaces, and 44.35% when excluding, 52.8% of maxillary treated surfaces compared to 24.4% of mandibular surfaces were arrested, and 53.9% of anterior surfaces compared to 30.6% of posterior surfaces were arrested with both comparisons showing statistical significance (p < 0.05), indicating that tooth surface location could affect caries arrestation rate following SDF application.

Results:
