MICROTENSILE BOND STRENGTH OF GIC AND RMGIC RESTORED TO CARIOUS TEETH TREATED WITH CARISOLV AND PAPACARIE- AN IN VITRO STUDY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 12
Abstract
BACKGROUND The overall longevity and clinical performance of adhesive restorative materials ultimately depends on the strength of the bond between the restorative material and the tooth surface. This study was performed to evaluate the influence of Carisolv and Papacarie on the microtensile bond strength (µTBS) of conventional glass ionomer cement (GIC) and resin modified glass ionomer cement (RMGIC) restored to caries-affected dentin. MATERIALS AND METHODS Sixty-four extracted carious primary molars were randomly divided into four groups depending on the chemomechanical caries removal agent used. Group 1A- conventional GIC with Carisolv, Group 1B- RMGIC with Carisolv, Group 2A- conventional GIC with Papacarie and Group 2B- RMGIC with Papacarie. All of the teeth were then restored with corresponding restorative materials. The samples were sectioned into 1 × 1 mm2 sticks using a hard tissue microtome and were subjected to tensile forces at a crosshead speed of 1 mm/min until failure of the bond occurred. µTBS were determined and subjected to statistical analysis using an independent sample ‘t’ test. RESULTS The microtensile bond strength of conventional GIC was higher with Carisolv as compared to Papacarie, which was statistically significant. RMGIC also showed a higher microtensile bond strength when restored to carious teeth treated with Carisolv, but this was not statistically significant. CONCLUSION It was seen that Carisolv did not adversely affect the microtensile bond strength of both conventional GIC and RMGIC.
