The goal of research and development is to develop an ideal restorative material. The ideal restorative material would be identical to natural tooth structure, in strength adherence and appearance. Hence the aim of the study was to evaluate the shear bond strength (SBS) of three recently evolved tooth colored restorative materials used in primary teeth dentine and verify, after SBS testing, the failure mode of the adhesive interface. Sixty extracted deciduous human molars with one of the proximal and occlusal surfaces free of caries were selected and randomly assigned into three groups according to the restorative material used. Teeth were sectioned parallel to occlusal surface to expose the mid coronal dentin of the non carious surface and the restorative materials were packed into a plastic straw (3 mm x 2 mm) covering the centre of flattened occlusal surface. SBS tests were performed and the obtained values were statistically analyzed using ANOVA and Turkey tests (p__ampersandsignlt;0.05). The failure mode analysis was performed with an Instron machine. Proportions were estimated and compared by using Pearson__ampersandsignrsquo;s chi-square test or Fisher__ampersandsignrsquo;s exact test (2-tailed) appropriately. From the results of the study, it may be concluded that the intra-group comparison showed, Group III (Admira) giving higher mean shear bond strength followed by group I (N 100). The lower bond strength is reported in-group II (Vitremer). The adhesive and cohesive modes of bond failures that are obtained in all three materials (N100, Vitremer, Admira) were not statistically significant.
