ABSTRACT:It is well known that the marginal leakage is a major problem that occurs along the tooth-restoration interfaces, resulting from passage of bacteria, fluids, molecules and other ions. This in-vitro study was conducted to assess the marginal leakage of newly developed ceramic-reinforced glass ionomer cement and to compare it with other conventional-glass ionomer cements. A sample size of twelve sound bovine incisors was selected for the current study. Standardised box-shaped cavities were prepared on the proximal tooth surfaces mesially and distally. Samples were randomly divided into three groups and restored as follows: Group-I (Fuji IX GP), Group-II (AH Fil+), and Group-III (GI Ceramic Reinforced Extra). The filled cavities were subjected to thermo-cycling process and then soaked in 0.5% methylene blue dye for testing the marginal leakage at the tooth-restoration interfaces. The dye penetration was assessed using a stereomicroscope and the degree of marginal leakage was evaluated using a specific scoring criteria as published previously. Statistically, the data were analysed using Kruskal-Wallis and Mann-Whitney U tests. GI Ceramic Reinforced Extra (Group-III) displayed the maximum leakage, followed by AH Fil+ (Group-II). Further, the minimum value of leakage was measured in Fuji IX GP (Group-I). However, there were no statistically significant differences in the marginal leakage of the three groups (p> 0.05). It was concluded that all the tested materials showed a significant degree of leakage to some extent.
