“…6,19,20 In the current study, higher mean bond strength values were needed for vertical dislodgment of the fiber posts luted after the AH26 sealer had previously been used as part of the root canal obturation compared with those canals where Endofil and Tubli-Seal sealers had previously been used as part of the root canal obturation. In addition, Carvalho and others 21 observed that a temporary sealing cement containing eugenol reduced the bond strength of adhesive systems.…”

“…14 However, eugenol, like all phenols, has considerable radical scavenging properties, and this is thought to inhibit composite resin polymerization. [15][16][17][18][19][20][21][22][23] There is little agreement between studies on whether this interaction is clinically relevant, 15,16,18 and it is unclear if the presence of eugenol and other components of root canal sealers, remnants of pulp tissue, and/or a residual smear layer impair post retention. 24 MultiCoret Flow (Ivoclar Vivadent, Schaan, Liechtenstein) is a dual-polymerizing, fluoride-containing composite resin designed for core buildup restorations of vital and nonvital teeth and luting of fiber posts.…”

“…The gutta-percha at the canal orifice was sealed with a hot burnisher; samples were stored in saline (Akkayan & Gulmez, 2002). Eugenol is shown to inhibit polymerization of composite resin (Dilts et al, 1986). Hence, a eugenol-free root canal sealer was used in the study.…”

Endodontically treated teeth with excessive loss of tooth structure would require to be restored with post and core to enhance the strength and durability of the tooth and to achieve retention for the restoration. The non-metallic posts have a superior aesthetic quality. Various core build-up materials can be used to build-up cores on the posts placed in endodontically treated teeth. These materials would show variation in their bonding with the non-metallic posts thus affecting the strength and resistance to fracture of the remaining tooth structure.Aims. The aim of the study was to assess the fracture resistance of three composite resin core build-up materials on three prefabricated non-metallic posts, cemented in extracted endodontically treated teeth.Material and Methods. Forty-five freshly extracted maxillary central incisors of approximately of the same size and shape were selected for the study. They were divided randomly into 3 groups of 15 each, depending on the types of non-metallic posts used. Each group was further divided into 3 groups (A, B and C) of 5 samples each depending on three core build-up material used. Student’s unpaired ‘t’ test was also used to analyse and compare each group with the other groups individually, and decide whether their comparisons were statistically significant.Results. Luxacore showed the highest fracture resistance among the three core build-up materials with all the three posts systems. Ti-core had intermediate values of fracture resistance and Lumiglass had the least values of fracture resistance.

Maximum Bond Strength of Dental Luting Cement to Amalgam Alloy

et al. 1989

Although dental amalgam is used frequently under artificial crowns for restoration of severely damaged teeth, there is little information available on the bond between luting cements and this alloy. This study was designed for determination of the strength of the bond between a dental amalgam alloy and three crown-luting cements. Cylinders of dental amalgam were joined in pairs, with use of a zinc-phosphate, a glass-ionomer, and an acrylic-adhesive resin cement. The tensile-fracture stress of 45 samples of each cement was measured with a universal testing machine, and subjected to a Weibull analysis. The fractured surfaces were examined under low magnification with use of a light microscope, and at low and high magnifications with use of a scanning electron microscope, for evaluation of the appearance of the fractured joints. The Weibull analysis demonstrated that the adhesive resin cement provided a stronger and more predictable bond than either the zinc-phosphate or the glass-ionomer cement. The appearance of the fractured surfaces gave no indication of the strength of the joints, a feature that is common to brittle materials. The results suggest that crowns placed on teeth offering a large amalgam-alloy surface could be retained more predictably with an adhesive resin cement.
