Comparative evaluation of shear bond strength of various esthetic restorative materials to dentin: An in vitro study

Abstract

Nano-ceramic and ormocer-based restorative materials showed better bonding potential to dentin as compared to GIC and Giomer.

Comparative Evaluation of Shear Bond Strength of Various Glass Ionomer Cements to Dentin of Primary Teeth: Anin vitroStudy

“…7 Though compressive and tensile strengths are important parameters to be evaluated but in the present study, we have evaluated shear bond strength as it assumes much importance to the restorative material clinically because of the fact that the major dislodging forces at the tooth restoration interface have shearing effect. Therefore higher shear bond strength implies better bonding of the material to tooth.…”

“…7 Its mechanism of bonding is based on bond formation between carboxyl groups of polyacrylic acid with hydroxyapatite at the tooth surface. 16 The lowest shear bond strength was observed for this group.…”

“…7 These forces are measured in terms of compressive strength, tensile strength, and shear strength. Shear bond strength is the resistance to forces that slides restorative material past tooth structure.…”

A Deep Morphological Characterization and Comparison of Different Dental Restorative Materials

“…In terms of marginal adaption it is worse than nanoionomer and RMGIc and presents also the maximum microleakage [23]. As compared to nanoceramic and Ormocer-based restorative material, Giomer holds the worst shear bond strength to dentin together with GI cement [24]. …”

Shear punch strength evaluation of nanocomposite and compomer, post-conditioning in dietary solvents – An in-vitro study

“…Nanocomposite offer numerous advantages such as reduced polymerization shrinkage, better gloss retention and wear resistance comparable to that of microfill and microhybrid composite resins. 4 It is expected that this novel nanocomposite system would be useful for all posterior and anterior restorative applications. 5 The performance of all restorations is dependent on the biodynamic environment of the oral cavity.…”
