Background: The tunnel concept accesses proximal dentinal carious lesions from the occlusal surface. This concept aims to preserve the marginal ridge and to minimize the loss of healthy tooth structure, thus saving clinical time as well as conserve the strength of tooth. The aim of the study was to investigate the fracture resistance of three different restorative materials in teeth with tunnel preparations. Methods and Materials: Fifty fully formed human maxillary premolars were selected for this in vitro study and divided into four main groups (N=10) Group 1: Biodentine, Group 2: Bioglass R, Group 3: Fiber reinforced composite, Group 4: Glass Ionomer Cement and Group 5: Control. Tunnel preparation was done using a round bur and fracture resistance was checked using a Universal Testing Machine (UTM). Results: The mean comparison of values between the groups was found to be statistically significant (F=3722.01, P value <0.05). To find out the pair wise comparisons, post-hoc Turkey test was applied and mean difference of all the comparisons was found to be statistically significant (P value <0.05). Conclusion: Considering the materials chosen to restore the tunnel prepared teeth, fiber reinforced composite proved to be superior in demonstrating good fracture resistance followed by Biodentine, Bioglass R and conventional glass ionomer cement.
