A novel furanone derivative and a polyacid constructed from it were synthesized, characterized and formulated into experimental high strength cements. The compressive strength (CS) and Streptococcus mutans viability were used to evaluate the mechanical strength and antibacterial activity of the cements. The effect of human saliva and aging were investigated. The antibacterial activity against L...

BACKGROUND Classic self-curing temporary cements obstruct the translucence of provisional restorations. New dual-cure esthetic temporary cements need investigation and comparison with classic cements to ensure that they are equally retentive and provide adequate translucence. The objective is to analyze by means of traction testing in a in vitro study the retention of five temporary cements. ...

Dental amalgam has been maligned as a filling material, both because of its clinical properties and its alleged effects on systemic health, but reports of its demise have been premature. As of 2008, 57 percent of dentists were placing amalgam (March 2008 Dental Products Report Survey). A large 2011 survey showed that dentists in the United States place more dental amalgam than composite for fir...

materials used in the body, especially the materials used in various oral cavity regions should be stable and passive without any interactions with the body tissues or fluids. dental amalgam, c omposite resins and dental cements are the materials of choice with such properties. the first attempts to produce active materials, which could interact with the human body tissues and fluids were promp...

The gap between a metal crown and an abutment tooth often leads to troubles such as secondary caries, pulpitis, periodontitis and so on. We expected that newly developed adhesive resins which adhere both dental alloy and tooth structure can minimize such troubles if they were used as setting materials of prosthetics. In this study, the degree of marginal leakage of adhesive resins was compared ...

This research aims to develop glass ionomer cement for dental application. Several factors that possibly affect the mechanical properties of our developed glass ionomer cements were studied. Developed cements were investigated for their compressive strength according to ISO 9917-1:2007 in comparison with the commercial glass ionomer cement. The different particle sizes and pre-cementation of gl...

PURPOSE Provisional cements are commonly used to facilitate retrievability of cement-retained fixed implant restorations. While the functional life spans of these cements are unpredictable, the relative retentiveness of various permanent and provisional cements between dental alloys and titanium abutments is not well documented. The aim of this study was to compare the uniaxial resistance force...
