0 NE of the prime considerations in the selection of a temporary filling material is the material’s ability to seal the margins of the cavity within which it is placed. Temporary filling materials are used in many phases of dentistry. During restorative dental procedures, temporary filling materials are used to protect the prepared tooth surface until the final restoration is placed. During end...

C3A ratio is one of the parameters that greatly affects rheological properties cementitious systems. With increase in ratio, water reducing admixtures and/or requirement increases to achieve target spread. Some are taken into account such as type rheometer, application method, homogeneous preparation mixture and admixture content determining water/cement (w/c) mixtures produced for measurement ...

Implant-supported dental prostheses can be retained by a screw or cement. Implant-supported fixed partial dentures have a passive fit. A passive fit means there is an internal gap between the abutment surface and the intaglio of the retainer to insure that there is no lateral pressure on the supporting implants or friction upon seating of the prosthesis. This gap is filled with cement for reten...

The purpose of this in vitro study was to evaluate microleakage along glass-fibre posts cemented with three different cements after cyclic loading. After post-space preparation, fifty obturated root canals were randomly divided into three experimental groups and two control groups. In group 1, Glassix posts were cemented using Harvard cement, in group 2, Fuji PLUS cement was used and in group 3...

Abstract Polycarboxylate superplasticizer is typically used to prepare a high-quality graphene oxide (GO) solution before mixing with cement grains. However, even if GO well dispersed in water, they tend re-agglomerate the alkaline hydration environment, thus seriously decreasing workability of fresh mixture. In this study, we propose more targeted method by synthesizing GO-coated silica fume (...

OBJECTIVE The aim of this study was to compare the microbial leakage of mineral trioxide aggregate (MTA), Portland cement (PC), Sealapex and zinc oxide-eugenol (ZOE) as root-end filling materials. STUDY DESIGN An in vitro microbial leakage test (MLT) with a split chamber was used in this study. A mixture of facultative bacteria and one yeast (S. aureus+E. faecalis+P. aeruginosa+B. subtilis+C....

BACKGROUND The selection of the appropriate luting cement is a key factor for achieving a strong bond between prepared teeth and dental restorations. AIM To evaluate the shear bond strength of Zinc phosphate cement Elite, glass ionomer cement Fuji I, resin-modified glass ionomer cement Fuji Plus and resin luting cement Panavia-F to Turkom-Cera all-ceramic material. MATERIALS AND METHODS Tur...

BACKGROUND The cementation of fixed implant-supported dental restorations involves the risk of leaving excess cement in the mouth which can promote biofilm formation in the peri-implant sulcus. As a result, an inflammation may develop. PURPOSE The aim of the present study was to investigate the clinical effect of two different luting cements on the peri-implant tissue. MATERIALS AND METHODS...
