Release and toxicity of dental resin composite
Dental resin composite that are tooth-colored materials have been considered as possible substitutes to mercury-containing silver amalgam filling. Despite the fact that dental resin composites have improved their physico-chemical properties, the concern for its intrinsic toxicity remains high. Some components of restorative composite resins are released in the oral environment initially during ...
متن کاملA Novel Antibacterial Dental Resin Composite
This study reports the synthesis and evaluation of a novel furanone-containing antibacterial resin composite. Compressive strength (CS) and S. mutans viability were used to evaluate the mechanical strength and antibacterial activity of the composites. With 5% to 30% addition of the furanone derivative, the composite showed no change in CS but a significant antibacterial activity with a 16% 68% ...
متن کاملFactors influencing repair of dental restorations with resin composite
The presentation of patients with dental restorations that exhibit minor defects is one of the commonest clinical situations in the practice of general dentistry. The repair of such restorations, rather than replacement, is increasingly considered to be a viable alternative to replacement of the defective restoration. This paper considers factors influencing the repair of direct restorations, i...
متن کاملContinuous-fiber preform reinforcement of dental resin composite restorations.
OBJECTIVES Direct-filling resin composites are used in relatively small restorations and are not recommended for large restorations with severe occlusal-stresses. The aim of this study was to reinforce composites with fiber preforms, and to investigate the effects of layer thickness and configurations on composite properties. It was hypothesized that fiber preforms would significantly increase ...
متن کاملDental erosion in workers exposed to inorganic acid fumes.
Changes in the colour and, structure of the teeth in workers exposed to strong inorganic acid fumes have, we believe, been recognized for many years by the workers themselves. Various measures of protection have, in fact, been unofficially adopted by them, and these we shall discuss below. Because these changes do not give rise to any loss of time or earnings, and because the affected workers h...
