Microtensile bond strength of root canal dentin treated with adhesive and fiber-reinforced post systems

Abstract

Nowadays, demand for esthetic restorations has risen considerably; thus, nonmetal esthetic posts made of either highstrength ceramics or reinforced resins, such as fiber-reinforced resin posts, have become more and more popular. Important characteristics of fiber-reinforced posts involve a modulus of elasticity similar to dentin and their ability to be cemented by an adhesive technique. A total of 36 maxillary incisors were divided into four groups. In this study, four adhesively luted fiber-reinforced (glass fiber, quartz glass fiber, zirconia glass fiber and woven polyethylene fiber ribbon) post systems were used. Post spaces were prepared by employing drills according to the protocol established for each group, and each post was adhesively luted with one of three adhesive systems. Three segments per root apical to the cementoenamel junction (CEJ) were obtained by sectioning the root under distilled water with a carbon spare saw. The samples (total of 108 sections) were 2.0±0.1 mm in thickness and they were stored individually in black film canisters with sterile distilled water. In order to determine the bond strength, the bonding area of each specimen was measured, and specimens were attached to a device to test microtensile strength at a speed of 1 mm/min. The analyses revealed no statistically significant differences between the adhesive systems and fiber-reinforced posts. (P> 0.05). However, the coronal portion of the root dentin had the highest bond strength. Adhesive systems used along with fiber-reinforced resin posts demonstrated reliable bonding.

Bonding Monolithic Ultra-Translucent Zirconia Restorations to Endodontically Treated Teeth Systematic Review

“…With ozonated water only as irrigant. after endodontic treatment demonstrated clinically by debonding of zirconia restoration and showed to increase the bond strength and this may be due to reverse the oxidative effect on dentin this is agreed with Başaran G et al [31], Laikuan Z et al [32], Khoroushi M [34]. Who stated that the antioxidant ability of sodium ascorbate helps neutralize and reverse the oxidizing effects of the NaOCl.…”

Effect of post-space irrigation with acid solutions on bond strength and dentin penetrability using a self-adhesive cementation system

“…In a recent meta-analysis, fibre posts were associated with higher overall survival rates than metal posts when used to restore endodontically treated teeth with extensive coronal destruction ( 2 ). Several characteristics favour the clinical choice of fibre posts; they include the more conservative removal of dentin, the aesthetic advantages, and greater treatment agility since their cementation does not require a laboratory step ( 3 , 4 ).…”
