The Effects of Antioxidant Application and Time Factor on Fiber Post Bonding to Root Dentin after Intracoronal Bleaching
Journal Title: International Dental Research - Year 2018, Vol 8, Issue 1
Abstract
Aim: The aim was to evaluate the effects of antioxidant application and delayed cementation on the bond strength of fiber posts after intracoronal bleaching. Methodology: Fifty-five maxillary central incisors were used. Root canals were enlarged using Reciproc system up to R40 instrument. Root canals were irrigated, dried with paper-points, and obturated with gutta-percha and a sealer. In 44 teeth, root canal fillings were removed 2-mm coronally and canal orificies were sealed with glass-ionomer-cement. A 37% CP gel was used to bleach the teeth. Five experimental groups were defined (n=11). G1: No bleaching, G2: Immediate FPC, G3: Immediate FPC after SA application, G4: 14-days delayed FPC, G5: 14-days delayed FPC after SA application. Push-out tests were performed. Statistical interpretations were made (α=0.05). Results: There was no significant difference among the groups in apical thirds (p>0.05). However, significant differences were detected among the groups in middle and coronal thirds (p<0.05). Conclusion: The 14-days delayed cementation seems to be a more reliable method than the SA application before FPC procedure after intracoronal bleaching.
