We evaluated the effect of water storage on fluoride release and mechanical properties of compomer restorative material. Fluoride release was recorded using a specific fluoride electrode. Flexural properties and fracture toughness were measured using a universal testing machine. Vickers hardness was measured using a micro-hardness tester. There was initial burst of fluoride release up to 1 w, w...

F OR some time there has been considerable interest directed toward the evalution of dental restorations from the physical property standpoint. The dental profession has long recognized that the success of a restorative appliance is dependent not only on the satisfaction of biologic criteria but, in addition, on the capabilities of the restorative materials as well as the tooth structure to res...

The AFM combined nanoindentation was performed to observe the ultrastructure of enamel rod from various section plans and positions while probing their mechanical and tribological properties of the area. The nanohardness and the elastic modulus of the head region of the enamel rods are significantly higher than that of the tail region and the axial-sectional plane. Both nanohardness and elastic...

In this in vitro study, the effects of a Cola drink, and fresh fruit juice (citrus) on the surface roughness on flowable composite and resin-modified glass ionomer cement (RMGIC) each was evaluated and compared. Using a brass mold 70 pellets each of flowable composite (Filtek™ Flow) and RMGIC tricure restorative material were prepared according to the manufacturer's instructions. Two groups (gr...

A new wear testing system, which carries out toothbrush wear and simulated occlusal wear tests alternately, was developed. Differences in wear behavior among three modes of wears, combined wear, toothbrush wear and simulated occlusal wear, were investigated using polymethylmethacrylate (PMMA) and two commercial resin composites (Z100, APX). The area of the material loss after each test was meas...

Many different materials and treatment options are available in esthetic and restorative dentistry. Various newer products, such as pressed ceramics, offer enhanced functionality; however, in thinner dimensions, they lack the inherent esthetic beauty of traditional materials such as feldspathic porcelain. As patient demands for better esthetics have increased in recent years, so too has the nee...

Oral and mucosal adverse reactions to resin-based dental materials have been reported. Numerous studies have examined the biocompatibility of restorative dental materials and their components, and a wide range of test systems for the evaluation of the biological effects of these materials have been developed. This article reviews the biological aspects of resin-based dental materials and discus...

Nanotechnology is gaining tremendous impetus due to its capability of modulating matter at smaller and smaller level which drastically changes the chemical, physical and mechanical properties of materials. Nanoparticles have been introduced into oral health care products with good potential to be extensively used for various dental applications. The purpose of this review is to highlight recent...

s: Aim: The aim of this research work was to compare and evaluate the hardness and flexural strength of three different commercially available fixed provisional restorative resins. Objective: The objectives of this research work are, to assess whether setting mechanism of fixed provisional restorative resins has an effect on the physical and mechanical properties and to compare and contrast the...

AIM To assess Croatian dentists' restorative treatment decisions on approximal caries lesions, including treatment threshold and restorative methods and materials. METHODS Croatian translation of the questionnaire assessing restorative treatment decisions on approximal caries, previously validated and used in Norway and Sweden, was distributed to a random sample (n=800) of Croatian dentists. ...
