Abstract :Objective: This study aims to evaluate the effects of five different caries removal methods on caries removal effectiveness according to microhardness and micro tensile bond strength values. Materials: In this study, for the microhardness test, micro-tensile bond strength test (n = 10) SEM analysis (n = 2), and a total of 72 human molar teeth were used. Caries lesions were removed with conventional (steel bur, ceramic bur, polymer bur) methods, chemomechanical method (Brix-3000), and fluorescence-aided caries excavation method (Siroinspect). Then, teeth were sectioned longitudinally through the cavity center and were subjected to the microhardness test, micro tensile test, and SEM atomic analysis. Statistical analyses were performed using one-way ANOVA and Duncan post-hoc tests. Results: A statistically significant difference was found between all caries removal methods and measurement levels at certain distances from the cavity floor (0, 25, 50, 75 μm) (p <0.05). As a result of the microhardness test, the group in which the fluorescence-aided caries removal method was applied was significantly higher than those in which the other caries removal methods were applied (p <0.05). According to the results of the micro tensile bond strength test, a significant difference was found between the groups where Siroinspect, BRIX-3000, steel bur caries removal methods were applied and the groups of polymer bur and ceramic bur (p <0.05). Conclusion: According to the results obtained from this study, the Siroinspect device in the category of FACE method can be a reliable alternative to traditional caries removal methods.
