【 摘 要 】

Loosening is the most common failure of fiber posts, mainly due to complex adhesion within the root canal. The main objective of this study was to determine if significant differences in adhesive resistance, using the push-out test, in the cementation of fiber posts with RelyX U-200® (U200) and Core Paste XP® (CPX) in different root regions. Material and methods A selection of 40 premolars were sectioned 15 mm from the apex, treated endodontically and then randomly divided in two groups of 20, using an Exacto translucent fiber post with U200 and CPX, respectively. After 24 hours, each sample was sectioned into cervical, middle and apical. The test push-out test was performed using a Tinius Olsen HK5-S machine to quantify the adhesive strength in Mega Pascals. The test Shapiro-Wilk, two-factor Anova and Tu
