UNLABELLED To evaluate bond strengths of different resin cements to two aluminum oxide-based ceramics. METHODS One hundred ten ceramic cylinders were produced and given four different surface treatments. Resin cement cylinders were then bonded to the ceramic cylinders using different resin cements and the bond strength was determined by shear testing to the breaking point. We were thus able t...

The injectability of Portland cement (PC) with several citrate additives was investigated for use in clinical applications such as vertebroplasty (stabilization of a fractured vertebra with bone cement) using a syringe. A 2-wt % addition of sodium or potassium citrate with PC significantly improved cement injectability, decreased cement setting times from over 2 h to below 25 min, while increas...

Introduction No dental material meets all requirements to be considered as an ideal restorative material should meet all the requirements, and should be biocompatible and non-toxic to the tissues. Biomaterials 1993;14: 906–16]. Most of these materials have to contact or interact with body tissue and fluids, so material’s selection must take into consideration not only mechanical and physical pr...

Abstract Calcium silicate hydrate (C-S-H) is the main hydration product of Portland cements. The partial replacement cements by supplementary cementitious materials can result in C-S-H with lower Ca/Si ratios and more aluminum alkalis. effect equilibration time on Al uptake was investigated using times from 7 days up to 3 years. Lower concentrations were measured solution after longer times. In...

Background: Aim of the study was to evaluate sealing ability of five different root end filling materials by dye penetration method. Materials and Methods: About 100 extracted maxillary central incisors were sectioned at Cementoenamel junction. Access cavities were prepared, instrumented chemo-mechanically, and obturated with laterally condensed gutta-percha and AH Plus sealer. Access cavities ...

OBJECTIVES Tricalcium silicate is the major constituent phase in mineral trioxide aggregate (MTA). It is thus postulated that pure tricalcium silicate can replace the Portland cement component of MTA. The aim of this study was to evaluate bond strength of methacrylate-based (MB) composites, silorane-based (SB) composites, and glass ionomer cement (GIC) to Biodentine® and mineral trioxide aggreg...
