EFFECT OF DENTIN CONTAMINATION WITH HEMOSTATIC AGENT ON MICROSHEAR BOND STRENGTH OF GLASS IONOMER CEMENTS

Abstract

The objective of this in-vitro study was to evaluate effect of hemostatic agents on microshear bond strength of different type of glass ionomer cements to dentin. 48 human extracted premolar teeth were used to prepare 96 specimens of dentin, the samples were divided into non-contamination and contamination groups. Each groups were divided into four subgroups according to different type of glass ionomer cement: 1) Ketac universal aplicap® 2) Fuji II LC capsule® 3) Fuji IX GP extra capsule® 4) Vitremer ®.The microshear bond strength test was performed using a universal testing machine at a crosshead speed of 1 mm/min. Data were analyzed by using two-way ANOVA and Tukey’s test (α = 0.05) There were no significant differences in microshear bond strength value between contaminated and non-contaminated groups (p > 0.05). Ketac universal group shows least bond strength (p < 0.05). No interaction between contamination with hemostatic agent and type of glass ionomer cements.
