Components of Fiber-reinforced Composite Resins
The clinical success of adhesive composite-resin restorations has changed the way that dentists treatment plan and treat periodontally mobile teeth. While adhesive composite resin provides for strong, durable, and esthetic single-tooth restorations, when placed to join teeth together, these materials—which are chemically brittle by nature—are susceptible to fracture and are not durable. When su...
متن کاملIndium light source for curing composite resins.
There is an existing problem of cumulative hazardous effect of violet and near ultra-violet light which is produced by standard polymerisation units. Another restrict is shallow depth of cure, particularly of darker composite shades in premolar and molar region. Searching for better light source we used indium resonance lines from several indium high pressure lamps and tested curing effect on t...
متن کاملInfluence of Light-Curing Units on Color Stability of Composite Resins After Aging
Background and Aim: The use of composite restorations has increased in recent years. One of the most important problems with composite restorations is the loss of consistency between the composite and tooth color, which in most cases requires replacement. Materials and Methods: In this study, the color stability of 40 disc-shaped specimens (10 mm in diameter and 2 mm in height) from two types ...
متن کاملTemperature changes caused by light curing units on dentine of primary teeth.
AIM This was to determine the temperature changes produced in dentine discs of primary teeth placed below a glass ionomer, microhybrid flow resin or microhybrid resin during the photocuring process with conventional halogen lamps and LEDs at different distances. STUDY DESIGN Experimental design. MATERIALS AND METHODS This in vitro study was carried out in the research laboratory of the Univ...
متن کاملEffect of composite shade, curing time and mode on temperature rise of silorane and methacrylate- based composite resins
Introduction: The present study was performed to evaluate the effects of light-curing modes and shades of methacrylate and silorane-based composite resins on temperature rise during polymerization of composite resins. Materials &Methods: In this in vitro study, ninety composite samples with two types of composite resin - methacrylate-based and a low-shrinkage silorane-based were prepared, in...
