Abstract

Introduction: Recently, clinical trials have assessed the effectiveness of Silver Diamine Fluoride (SDF) as an indirect pulp capping material (IPC) in primary teeth. This systematic review aimed to assess the evidence presented in these trials.

Data sources: A comprehensive search identified relevant studies through five electronic databases (PubMed, Scopus, ClinicalTrials.gov, ScienceDirect, and Cochrane). Search strategies were designed using the PICO model to identify all studies that investigated SDF as an IPC compared to calcium hydroxide (CaOH) or mineral trioxide aggregate (MTA). Quality assessment and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) were used to assess the level of evidence.

Study selection: Four clinical trials were found to be suitable for inclusion in the qualitative synthesis and three studies were included in the quantitative analysis. Three studies compared SDF with CaOH and only one study compared SDF, CaOH, and MTA. Only one randomized controlled trial (RCT) had a low risk of bias, and the non-RCT study had a moderate risk of bias. The level of evidence based on the GRADE was low. Three out of four studies showed higher clinical and radiographic outcomes with SDF than with CaOH. One non-RCT study showed that SDF resulted in the least reparative dentin at the 6-months follow-up. The meta-analysis showed a non-significant difference between the SDF and CaOH groups (P = 0.36).

Conclusion: There is little evidence showing a higher clinical and radiographic outcome of SDF compared to CaOH as an IPC material in primary molars.

Clinical significance: This systematic review updates pediatric dentists regarding the effectiveness of using SDF as indirect pulp caping in primary teeth.
