Comparison of Retention between Two Dental Root Canal Core Build Up Materials and Silanized and Non-Silanized Glass Fibre Posts: An Invitro Study
Background: Various resin-based core builds up materials are commercially available in market but their clinical use should follow recommendations of bond strength measurement studies.
Objective: to evaluate the retention between two commercially available core build up materials and silanized and non-silanized glass fibre posts.
Methodology: The retention between two commercially available core build up materials (Core X Flow and Light Core) and Silanized and Non- Silanized glass fiber posts with ten samples in each group were assessed using ‘pull out test’ in universal testing machine. Student’s unpaired ‘t’ test was used for inter group comparison by fixing significance level at p ≤ 0.05.
Results: The retention force was higher in silanized fibre post group compared to non-silanized posts (p=0.02). Among the silanized posts, the retention force was significantly higher in CORE X FLOW group compared to LIGHT CORE group (p=0.03). Conclusion: The retention of posts improved with silanization. With silanization, the retention force was significantly higher with ‘CORE X FLOW’ compared to ‘LIGHT CORE’ core build up material.
