“…it was rejected for MB and MB II, as the µTBS values were decreased by storage and the µTBS was significantly influenced by the dentin region; bond strength to cervical dentin was higher than that to apical dentin for both materials. It was speculated that the higher µTBS in cervical dentin was due to increased permeability of dentin to resin penetration and an increased crosssectional area in the cervical region 31) . In addition, apical dentin is more sclerotic or transparent than the other region depending on the age 32) .…”

The purpose of this study was to investigate bond durability of MMA-based adhesives to root dentin in a simulated complete vertical root fracture (CVRF). The fractured fragments of human premolar root were reattached using Super-Bond C&B (SB; Sun Medical), M-Bond or M-Bond II (MB or MB II; Tokuyama Dental). After storage for 1 day, 1 month, 6 months and 1 year, the reattached specimens were subjected to microtensile bond strength (µTBS) test at cervical and apical regions. Results showed that µTBS was significantly higher to cervical dentin than to apical dentin in MB and MB II, but not SB (p<0.05). Significant decrease in µTBS was found for MB and MB II after 1 year, whereas no significant difference was found for SB (p<0.05). Analysis of failure mode by SEM indicated differences over time. In conclusion, significant differences were found in the regional bond durability among MMA-based adhesives used to restore CVRF, that may lead to different clinical performances.

“…This failure mode had also been reported in several other studies. [16][17]29,[32][33] This may be explained by an increased permeability associated with one-step self-etch ED primer, 16,33 which behaved as a semi-permeable membrane after polymerization and compromised the bond strength of the resin cement. "Mushroom-like blisters," which were continuous with the lumen of patent dentinal tubules, were observed in the SEM of the PF-control and PF-tungsten carbide groups (Figure 2a).…”

Clinical RelevanceFor Panavia F2.0, higher bond strengths are achieved on dentin surfaces prepared with tungsten carbide bur. Proper bur selection is essential to optimize dentin adhesion of self-etch resin luting cements. SUMMARYThis study examined the effects of using two different burs for dentin surface preparation on the microtensile bond strength (µTBS) of three resin luting cements. Flat, deep dentin surfaces from 45 extracted human third molars were divided into three groups (n=15) according to bur type: (i) diamond bur and (ii) tungsten carbide bur. The controls were abraded with #600-grit SiC paper. Both burs operated in a high-speed handpiece under water-cooling. Composite blocks were luted onto the dentin using one of three cements: RelyX ARC (ARC, 3M ESPE), Panavia F2.0 (PF, Kuraray) and RelyX Unicem (UN, 3M ESPE) following the manufacturers' instructions. For ARC, the dentin surface was treated with 32% phosphoric acid. The bonded specimens were stored at 37°C for 24 hours and sectioned into 0.9 x 0.9 mm beams for µTBS testing. The data were analyzed using the two-way ANOVA and StudentNewman-Keuls tests. Representative fractured beams from each group were prepared for fractographic analysis under SEM. Two-way ANOVA revealed that the effects of "dentin surface preparation" and "luting cement" were statistically significant (p<0.001); however, the interaction of these two factors was not significant (p>0.05). ARC showed no significant difference in µTBS among the three differently prepared dentin surfaces. The µTBS of PF and UN was significantly lower when bonding to dentin prepared with a

“…Etching of dentin followed by water rinsing. Subsequently the hydrophilic primer is applied to increase dentin surface energy and to facilitate the penetration of the bonding resin monomer, generating a mixed zone of resin-entangled collagen fibrils, known as hybrid layer [26]. The quality of resin dentin adhesion can greatly be influenced by the duration of etching process, and by the amount of dentin surface humidity following rinsing of the acid and prior to resin infiltration.…”
