This study evaluated the influence of the cementation system on the regional push-out bond strength and failure pattern of fiber posts to radicular dentin. The roots of 48 extracted human incisors were prepared and divided into 3 groups (n=16), according to the cementation system: AdperScotchbond Multi-Purpose + resin cement RelyX ARC (SBMP+ARC); Adper SingleBond 2 + RelyX ARC (SB+ARC) and; RelyX U100 self-adhesive resin cement (U100). The posts were cemented as per manufacturer's instructions for each cementation system. After 1 week, the roots were sectioned transversely into 6 discs. Two discs were obtained from the cervical, middle and apical thirds and the push-out test was carried out. The failure pattern was examined on all debonded specimens. The data were analyzed by two-way repeated measures ANOVA and Tukey's test. When U100 was used, no statistically significant difference (p>0.05) was observed among the different root regions. Statistically higher push-out bond strength values were detected in the cervical third for SBMP+ARC and SB+ARC (p<0.05). The U100 showed significantly more mixed failures than SBMP+ARC in the apical third (p<0.05). In conclusion, the self-adhesive cement RelyX U100 was the only cement not sensitive to the root canal region.

“…13) are more retentive than tapered posts. 34 However, the preparation of a parallel-sided post channel, and subsequent cementation of a square-ended parallel post may produce increased stress in the narrow and tapering root-end 35 (Fig. 14a) and predispose to root fracture.…”

Crowns and extra-coronal restorations: Endodontic considerations: the pulp, the root-treated tooth and the crown

“…In their study of parallel versus tapered post systems, Torbjornet et al 34 noted that in fact the type of post may be of minimal importance to the risk of root fracture if the tooth is covered by a complete crown with a good ferrule effect at the crown margin area. Their comments were not, however, directed to posts involving active methods of retention.…”
