Numerous positive properties of glass ionomer cements including biocompatibility, bioactivity, releasing of fluoride and good adhesion to hard dental tissue even under wet conditions and easy of handling are reasons for their wide use in paediatric and restorative dentistry. Their biggest drawbacks are the weaker mechanical properties. An important step forward in improving GIC's features is th...

The continuous technological advance and increasing availability of new dental self adhesive resin cement in the market, coupled to the demands of daily clinical practice, have made the determine mechanical properties. This study evaluated the shear bond strength of ceramics cemented by three different dental self-adhesive resin cements. Shear bond strength was measured with an Instron servo hy...

INTRODUCTION The aim of the present study was to investigate whether the concentration of arsenic (As) released from gray or white mineral trioxide aggregates (MTAs) met the requirement of the International Standards Organization (ISO) for dental cements. METHODS Sample preparations were carried out according to the ISO methods. After centrifugation of dissolved samples, As (III) concentratio...

1. The following dental cements are listed in order of decreasing mean bonding strenghts on varnish-free dentin: polycarboxylate, zinc phosphate, EBA, Fynal, and CBA. 2. The application of either Copalite or Varnal decreased the dentinal bonding strength of polycarboxylate and zinc phosphate cements. There was no change for CBA cement. 3. The application of Copalite and Varnal increased the den...

background: with regard to potential retrievability of cement-retained implant restorations, the retentive strength of the luting agents is critical. the aim of this study was to evaluate the retention values of implant-supported metal copings using different luting agents. materials and methods: twenty iti implant analogs and solid abutments of 5.5-mm height were embedded vertically in autopol...

In literature, the primary function of a dental cement is to fill the space between restorative material (definitive or provisional) and tooth preparation (or implant abutment), as well as to enhance the resistance to restoration dislodgement during function [1,2]. Of utmost importance, the long-term success of a restoration is heavily dependent on the proper selection and manipulation of denta...
