Comparison of Microleakage of Different Silver Diamine Fluoride Formulations (Solutions and Gel) with Resin-modified Glass Ionomer Cement Restoration on Human Teeth by Dye Penetration Method Using Stereomicroscopy: An In Vitro Study.

INTRODUCTION

Silver-modified atraumatic restorative therapy (SMART) is the silver diamine fluoride (SDF) treatment followed by glass ionomer cement (GIC) restoration to help arrest the progression of the caries without requiring local anesthesia and cavity preparation. There is no comparison in the literature regarding the microleakage and potential of secondary caries with the aforementioned approach. Also, recently, a new formulation of SDF, that is, SDF gel, is available in the market, which could be a better material due to its ease of application and control over area of application.

MATERIALS AND

METHODS

This is an in vitro study that included 60 extracted human premolar teeth, divided into four groups of 15 each: group I-SDF solution (FAgamin), group II-SDF solution (e-SDF), group III-SDF gel (KEDO), and group IV-SDF + KI (KEDO). Class IV cavity preparation was done, after which SDF was applied and cavities were restored with resin-modified glass ionomer cement (RMGIC). Thermocycling, dye penetration, and sectioning were done, followed by evaluation under a stereomicroscope.

RESULT: Level of dye penetration at enamel and dentinal margins were measured and there was statistically significant difference in all the four groups at enamel and dentinal margins, with p-value < 0.00001 and < 0.00001, respectively.

CONCLUSION

Group III (SDF gel-KEDO) had least microleakage, followed by group I (FAgamin), group II (e-SDF), and group IV (SDF + KI).
