Abstract
Context: Endodontically treated premolars are currently restored with direct bonded techniques in conservative manner enabling them to bear functional stresses homogeneously. Aim: The study aimed to evaluate the effect of placement of compactable glass fibers in reinforcing the endodontically treated teeth in a novel conservative manner. Settings and Design: study. Materials and Methods: POST followed by composite, and (E) vertical glass fibers within 3 mm of the coronal root canal space and buccopalatal flaring of the coronal fibers followed by composite. After conditioning and thermocycling, specimens were loaded under a universal testing machine to evaluate fracture resistance and fracture pattern of specimens. Statistical Analysis Used: Tukey's test for intergroup comparison, and Chi-square test for analysis of favorable and unfavorable fracture. Results: < 0.001). Conclusion: POST used in conservative manner improved fracture strength of teeth significantly.
