Abstract

Background:  Silver diamine fluoride (SDF) solution is being used in arresting dental caries in countries throughout the world since the 1970s. The mechanism of action is that silver-salts promote dentin sclerosis/calcification, silver nitrate has anti-microbial effects, and fluoride helps in the process of remineralization and prevention. The aim of this study is to evaluate the bond strength of posterior restorative material with tooth treated with silver diamine fluoride using universal testing machine
Materials and Methods: 60 premolar tooth were sectioned transversally and each root was embedded in cold-cure epoxy resin. The labial tooth surface was wet ground using silicon carbide discs to prepare a flat superficial dentin. The tooth were conditioned using 10% polyacrylic acid, and divided accordingly. Two increments of resin composite were placed into the plastic tubes of size 5mm X 3mm and each increments were light polymerized for 40 seconds. The same procedure was followed for glass ionomer cement. All specimens were stored at 37 in water for 24hrs before testing. The push out bond strength analysis was tested using the universal testing machine.
Results: The maximum push out bond strength is seen in GIC in dentin-21.85 N/mm, followed by the group with composite-19.27 N/mm and with the lowest value in the group containing SDF+KI+GIC-3.601 N/mm.
Conclusion: Addition of Potassium iodide used to reduce the staining of the SDF does affect the bond strength of the restoration to dentin. GIC has the best bond strength with tooth, followed by composite among the groups.
