142 - Silver Diamine Fluoride Use During SARS-CoV-2 Pandemic for Non-Aerosol-Generating Procedures

Purpose: The purpose of this study is to examine the proportional use of SDF pre-Covid (2019), during the Covid shutdown (March 2020-late April 2020), early recovery (mid-May 2020 to August 2020), late recovery period (September 2020-December 2020), and continuing recovery (2021-2023) of the SARS-CoV-2 pandemic due to recommendations for non-aerosol-generating procedures. 

Methods: Data in this study was obtained through Fluent Dental Solutions, a national dental data warehouse. CDT Codes for Interim Caries Arresting Medicament (D1354), Limited Re-evaluation (D0170), and Operative Codes (D2000-2999) were assessed. Other variables included treatment dates, and patient and dentist information. A retrospective analysis of dental claims made over a five-year period was completed, and data points were used to determine the first treatment rendered. Analyses were conducted using generalized linear mixed models and a two-sided 5% significance level was used for all tests.  

Results: There was a significant increase in SDF usage in each of the Covid periods as compared to pre-Covid SDF use (P < .001). During continuing recovery, posterior teeth were more likely to have SDF applied than anterior teeth (P < .001). However, this was not seen in the Covid shutdown, early, or late recovery periods (P>.05).

Conclusion: Quantitatively, SDF usage proportionally increased during each of the Covid periods as compared to pre-Covid SDF use, suggesting a shift toward non-aerosol-generating procedures. This could guide decision-making for operative treatment and the use of SDF as a treatment option in times when traditional aerosol-generating procedures are not available.
