Abstract

Background and Aim: Composite resin cores with pre-fabricated posts are commonly used to restore endodontically treated teeth. This study compared the sealing ability of Core Max II and Clearfil photocore by Panavia F 2.0 cement, with and without adhesive.Materials and Methods: Crowns of sixty recently extracted human second premolar teeth were cut 3 mm above the CEJ. After preparing proximal boxes and finishing root canal therapy, the teeth were randomly divided into four groups of fifteen teeth each. The Dentatus # 2 Long pins with approximately 8 mm length were cemented in canals. In the first two groups, Core Max II with adhesive (group 1) and without adhesive (group 2) was applied for cementation. Pins in the other two groups were cemented with Clearfil photocore composite and Panavia F 2.0 cement with adhesive (group3) and without adhesive (group 4). After 24 hours, specimens were thermally cycled for 500 cycles. Then the teeth were sealed with nail varnish beyond 1 mm of restoration margins and immersed in a 0.5% fuschin solution. Afterwards samples were embedded in epoxy resin, sectioned mesiodistally and observed under 20 x magnifications. The microleakage was recorded as the amount of dye penetration in the route connecting the proximal boxes to the end of the pin. ANOVA and Tukey tests served for statistical analysis.Results: The first (61.57±14.24) and fourth (12.37±13.85) groups had the highest and the lowest value of microleakage, respectively. Using adhesive for both cements reduced microleakage (P<0.05).Conclusion: Panavia cement had less microleakage compared to Core Max II. Key words: DENTAL LEAKAGE - POST AND CORE TECHNIQUE - COMPOSITE RESINS.Corresponding Author: Dr. Moosavi H., Assistant Professor, Department of Operative Dentistry, School of Dentistry, Mashhad University of Medical Sciences.
