Effect of 1-Piece Post and Core Fabrication Techniques on Fracture Strength

Journal of Applied Biomaterials & Functional Materials, 2015
Purpose The purpose of this in vitro study was to evaluate and compare the fracture strengths of post and core systems produced with different fabrication techniques and materials. Methods Forty extracted human single-root premolars were used in this study. After root canal treatment, the teeth were randomly divided into 4 groups of 10 each as follows:
