The choice of luting agents contributes a significant role in retention of cement retained implant restorations and their precise tensile behaviour needs to be investigated further. The aim of present study is to estimate and compare the difference in tensile bond strength between implant abutments and all ceramic restorations luted with four luting agents. An experimental, single blinded, in-v...

PURPOSE The aim of this study was to evaluate the effect of provisional cements on the adhesion of resin bonded indirect restorations and determine the best method for avoiding adverse effects. MATERIALS AND METHODS Forty-five bovine incisors were selected, and the enamel removed with a 600-grit SiC abrasive disk to expose superficial dentin. Provisional restorations of acrylic resin were cem...

PURPOSE The aim of this study was to evaluate the effects of abutment diameter, cement type, and re-cementation on the retention of implant-supported CAD/CAM metal copings over short abutments. MATERIALS AND METHODS Sixty abutments with two different diameters, the height of which was reduced to 3 mm, were vertically mounted in acrylic resin blocks with matching implant analogues. The specime...

Seven zinc oxide-eugenol cements with compressive strengths from 200 psi to 8,000 psi were used for temporarily cementing completed inlays, crowns, and bridges. The effectiveness of each cement in a variety of clinical situations is presented. Cement of 1,000 psi met the requirements of typical clinical cases most frequently. The cements of compressive strength 200, 400, 600, 2,200, and 3,500 p...

introduction: ferric sulfate pulpotomy is a safe and effective method of the pulpotomy of primary teeth. but the results of different studies indicate low success rate of ferric sulfate pulpotomy in comparison to formocresol pulpotomy and a portion of these failures may be related to stimulating and harmful effects of zinc oxide eugenol paste. the aim of this study was to determine and compare ...

OBJECTIVES An important factor that interferes with the bonding between the root canal wall and resin cement is the root canal sealer remnant. There is controversy about the effect of eugenol-containing sealers on the bond strength between resin cements and fiber post. The aim of this study was to evaluate the effect of the type of endodontic sealer on the bond strength of FRC posts cemented wi...

The objective of this study was to evaluate the sealing ability and antibacterial activity of Ca3SiO5/CaCl2 composite cement. Fifty maxillary anterior teeth were instrumented according to step-back technique and filled with experimental and control materials. To evaluate the sealing ability, a fluid transport model using glucose was employed for quantitative analysis of endodontic microleakage....

OBJECTIVE This study evaluated in vitro the influence of an eugenol-based sealer (EndoFill) on the retention of stainless steel prefabricated posts cemented with zinc phosphate and resin-based (Panavia F) cements after different periods of root canal obturation, using the pull-out test. MATERIAL AND METHODS Sixty upper canines were decoronated and the roots were embedded in resin blocks. The ...

ÖZET Aim: The purpose of this laboratory investigation was to evaluate the bond strength of temporary cement [(Provicem, Procem (eugenol-free), Tempbond (eugenol)] to commonly used core build-up materials. [Composite resin (President), Compomer (Dyract AP), glass-ionomer cement (Ionofil), resin modified glassionomer cement (Vitremer) (RMGIC)]. Materials and Methods: Sixty specimens were fabrica...
