489 - The Effect of Silver Diamine Fluoride on Stainless Steel Crown Retention of Hall Crowns

Background: Silver diamine fluoride (SDF) and Hall Crowns are minimally invasive treatment modalities that have increased in popularity as the medical management of dental decay becomes more commonplace. As such, there is currently no research available regarding SDF’s effect on the retention of stainless-steel crowns.

Objective: This study aims to determine whether SDF applied to extracted primary molars affects the retention strength of Hall Crowns.

Materials and

Method: In this experimental study, thirty-eight primary molars with intact anatomical crowns that were recently extracted without structural defects were fixed in acrylic, randomly divided into one of two groups, scanned using a DOF dental lab scanner, and subjected to crown retention testing following application of SDF and Hall Crown placement with an appropriately fitted and crimped but modified SSC. Retention strength was tested with the use of an Instron 5566 Universal Testing Machine with the recording of data via Instron Bluehill included software for windows. Non-parametric Wilcoxon rank sum tests were used to compare retention strength between the control group and the experimental group.

Results: The results of the study showed that there was no significant difference in the retention strength of hall crowns with prior SDF application.

Conclusion: The findings of this study suggest that SDF does not significantly affect the retention strength of Hall Crowns in primary molars. Further research is needed to confirm these results and to explore the potential benefits and drawbacks of using SDF in conjunction with Hall Crowns.
