摘要

STATEMENT OF PROBLEM: The smear layer covering root canal dentin as a result of post space preparation procedures may negatively affect the retention of adhesively cemented glass fiber-reinforced resin posts. PURPOSE: The purpose of this study was to evaluate the retention of airborne-particle-abraded glass fiber posts luted with 3 different bonding systems after conditioning the canal dentin with acidic conditioning methods. MATERIAL AND METHODS: Post spaces were prepared in 6 groups of 8 endodontically treated single-rooted teeth. Glass fiber-reinforced resin posts were airborne-particle abraded and luted after etching the canal dentin with phosphoric acid and/or applying XP Bond, Clearfil New Bond, or ED Primer. The groups with their respective etching time, primer, and cement combinations were as follows: XP15: 15 seconds of phosphoric acid treatment, XP Bond and Calibra; XP30: 30 seconds of phosphoric acid treatment, XP Bond and Calibra; NB15: 15 seconds of phosphoric acid treatment, Clearfil New Bond and Panavia 21; NB30: 30 seconds of phosphoric acid treatment, Clearfil New Bond and Panavia 21; ED: ED Primer only and Panavia 21; ED15: 15 seconds phosphoric acid treatment, ED Primer and Panavia 21. Specimens were stored in water for 30 days and subjected to simulated aging conditions. Post retention was measured in tension at a crosshead speed of 2 mm/min. Data were analyzed using Mann-Whitney and Kruskal-Wallis tests followed by post hoc comparisons using Langley method (alpha =.05). The dislodged posts and canals were examined microscopically at x8 and x20 magnification to evaluate the mode of failure. RESULTS: For each group, the mean (SD) retention in N was: XP15: 376.8 (39); XP30: 305.5 (27); NB15: 370.3 (31); NB30: 297.6 (52); ED: 301.6 (43); ED15: 373.8 (46). The retention values of ED15, NB15, and XP15 were significantly higher than those of ED, NB30, and XP30 groups, respectively. Microscopic evaluation demonstrated that the failure mode was primarily mixed. CONCLUSIONS: Luting posts with Panavia 21 or Calibra after etching the dentin with phosphoric acid for 15 seconds produced significantly higher retention values than treating dentin for 30 seconds or with ED Primer, only.
