Abstract:Objective:The current study investigated the thermal conductivity of dimethacrylate-and silorane-based composite resins at different polymerization times and modes.
Materials and Method:Forty dentin discs (8 mm diameter, 1.5 mm thick) were obtained from caries-free human molar teeth. Filtek Silorane (3M ESPE, Minnesota, USA) and Filtek Z550 (3M ESPE, Minnesota, USA) composite were polymerized with a LED (Light-Emitting-Diode) curing device (Valo, Ultradent Products Inc., Utah, USA), in two modes in different t… Show more
The paper presents and experimental study upon several types of materials used for dental works (especially prosthetic works) after prolonged use (over 10 years). The issues that lead to the necessity of changing the prosthetic works are the results of multiple types of wear. Our aim is to determine the extension of damage by digital microscopy, probable causes and analyze the benefits and disadvantages of the most used materials in prosthetic works.
