To evaluate different protocols for recementation of dislodged glass fiber posts (GFPs).The root canals of 50 bovine incisors were prepared to receive GFPs, which were conditioned with 24% hydrogen peroxide, silanized, and cemented with a self-adhesive resin cement. After light curing, the specimens were submitted to a pullout test. The dislodged GPFs were distributed into five experimental groups (n = 10 each) according to surface treatment for recementation: NT = no treatment; SI = silane; ET = 92.8% ethanol/silane; HP = 24% hydrogen peroxide/silane; AL = airborne-particle abrasion (50-μm alumina)/silane. The GFPs were recemented with the same self-adhesive resin cement, and specimens were submitted to a second pullout test. Data were analyzed by Student t test and one-way ANOVA (α = .05).For all groups, the recementation bond strength was higher than the strength obtained after the first cementation (P.05). There were no statistical differences among the experimental recementation protocols (P = .096).All recementation protocols might be reliably applied since they led to higher bond strength than the first cementation. |
