PURPOSE There is limited information in the literature regarding the effect of different endodontic sealers on the bond strength of fiber posts luted with core buildup materials. The purpose of this study was to evaluate the effect of three different root canal sealers on the retentive strength of prefabricated fiber posts luted with a composite resin(More)
The appropriate convergence angle (CA) for adequate retention and resistance of cast crowns has always been a matter of research and discussion. The purpose of this study was to measure the CA of tooth preparation for single crown (SC) or as abutments for fixed partial denture (FPD) carried out by final-year undergraduate dental students at the College of(More)
STATEMENT OF PROBLEM The effect of the surface treatment of zirconium oxide posts on their push-out bond strength is controversial. PURPOSE The purpose of this study was to compare the effects of 2 surface treatments on the bond strength of zirconium oxide posts cemented with different cements and to assess the failure mode. MATERIAL AND METHODS Seventy(More)
OBJECTIVE The aim of this study was to investigate the effect of different luting agents on the bond strength of zirconium oxide posts in root canals after artificial ageing. MATERIAL AND METHODS Thirty single-rooted extracted teeth were collected. Post spaces were prepared. Custom milled zirconium oxide posts (Cercon, Degudent) were fabricated. Specimens(More)
OBJECTIVE This in vitro study evaluated the bond strength of custom cast and prefabricated posts luted with resin or zinc phosphate cements into unobturated canals of extracted teeth. METHOD AND MATERIALS Forty-eight custom cast and prefabricated posts were placed into extracted single-rooted human teeth. Post-cavity preparation was 1.5 mm in diameter and(More)
STATEMENT OF PROBLEM Fiber posts can fail because of loss of retention; and it is unknown which luting agent provides the highest bond strength. PURPOSE The purpose of this study was to investigate the tensile bond strength of glass fiber posts luted to premolar teeth with 6 resin composite luting agents. MATERIAL AND METHODS Ninety-six single-rooted(More)
PURPOSE The purpose of this study was to evaluate heat generation at the implant surface caused by abutment preparation using a diamond bur in a high-speed dental turbine in vitro at 2 different water-coolant temperatures. MATERIALS AND METHODS Thirty-two titanium-alloy abutments were connected to a titanium-alloy implant embedded in an acrylic resin(More)
STATEMENT OF PROBLEM Currently, no standard luting protocol exists for fiber posts. In addition, no agreement has been reached on the time interval between canal obturation and post space preparation and cementation. PURPOSE The purpose of this in vitro study was to evaluate the retention of fiber posts cemented with 3 different types of cement: Paracore,(More)
OBJECTIVE The purpose of this study was to compare the effect of eugenol-based and resin-based endodontic sealers on the push-out bond strengths of prefabricated fiber posts luted with different resin cements. METHOD AND MATERIALS Ninety prefabricated fiber posts were luted into extracted singlerooted teeth with one of three resin cements (Variolink II,(More)
STATEMENT OF THE PROBLEM Post retention is crucial factor in restoration survival. Posts are commonly failed due to loss of retention. It is unknown which luting agents would provide the maximum bond strength for Locator overdenture posts. AIM The aim of this study was to evaluate the bond retentive strengths of Locator overdenture posts cemented with 7(More)
