Abstract: Aim: This study aims to evaluate the effects of traditional and conservative access cavity designs on the preservation of pericervical dentin thickness and fracture strength in root canal-treated molars with Class II caries, restored with conventional and fiber-reinforced composites. Methodology: After pre-operative CBCT, samples were divided into four groups based on cavity design and restored with different composites. The pericervical dentin thickness was evaluated. Results: Traditional access showed the highest reduction in dentin thickness and lowest fracture strength. Conclusion: Conservative cavity designs better preserve dentin and structural integrity than traditional designs, with fiber-reinforced composites not compensating for reduced strength.
