Effects of different luting agents on bond strengths of fiber-reinforced composite posts to root canal dentin


Rödig, T; Nusime, A K; Konietschke, F; Attin, T (2010). Effects of different luting agents on bond strengths of fiber-reinforced composite posts to root canal dentin. The Journal of Adhesive Dentistry, 12(3):197-205.

Abstract

PURPOSE: To evaluate the bond strength between two fiber posts (FRC Postec and DT Light Post) and different composite resins following different surface treatments of the posts. MATERIALS AND METHODS: One hundred sixty extracted teeth were divided into sixteen groups (n = 10). After pretreatment of the post surface with (1) no treatment, (2) silanization, (3) sandblasting + silanization or (4) tribochemical coating, the posts were either luted with the resin cements provided by the manufacturers of the post system or with a core buildup material. Push-out tests were performed in a universal testing machine until the post segment was dislodged from the root section. Data were analyzed using ANOVA. Multiple comparisons were performed using Tukey's test. RESULTS: FRC Postec achieved significantly higher bond strengths than DT Light Post (p < 0.0001). Cementation with the core buildup material showed significantly higher bond strengths than the resin cement provided by the post manufacturers (p < 0.0001). CONCLUSION: Post type, type of surface treatment and type of resin cement were significant factors for bond strength. Luting with a core buildup material significantly increased the bond strengths.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
