Abstract


The purpose of this study was to verify through mechanical tests of push out the strength adhesive bonding between the intra-root teeth of cattle and pins of carbon fiber (Reforpost/Angelus) and if there was any difference between the cervical, and apical average, using two adhesive systems (Variolink II/Ivoclar and Cement Post/Angelus). Twelve uni-root teeth were selected, randomly divided into two groups: Group 1 (Variolink II), Group 2 (Cement Post). The roots were split across three discs of 2.0mm in thickness, called cervical thirds, middle and apical. Through analysis of variance (Anova p = 0,224) there was no statistically significant difference between the thirds.
