The color stability of silorane- and methacrylate-based resin composites.
The purpose of this study were to evaluate the discoloration of a silorane-based resin and two methacrylated-based resin composites upon exposure to different staining solutions coffee, red wine, porcine liver esterase and distilled water for 7 days. The colors of all specimens before and after storage in the solutions were measured by a spectrophotometer based on CIE Lab system, and the color ...
متن کاملevaluation of microleakage in class v cavities filled with methacrylate-based versus silorane-based composites
statement of problem: despite the increasing demand for tooth-colored restorations in dentistry, polymerization shrinkage and marginal microleakage still remains a problem. objectives: the purpose of the present study was to evaluate microleakage in three different resin composites, p90, z250 and z250 xt, in class v cavity of permanent human premolars. materials and methods: standardized class ...
متن کاملEffects of Carbamide Peroxide Bleaching Gel on Color of Silorane- and Methacrylate-based Resin Composites
Introdouction: Bleaching has become a common treatment for improving the appearance of natural teeth. However, the need to protect dental restorations from bleaching agent exposure is inevitable, as these agents may change the color of restorative materials by oxidation. Filtek P90 composite resin has recently been introduced with the aim of decreasing polymerization shrinkage. The purpose of...
متن کاملتاثیر سیکل مکانیکی بر ریزنشت کامپوزیت‌های با انقباض کم با بیس متاکریلات در مقایسه با کامپوزیت سیلوران و ارزیابی تطابق لبه‌ای آنها توسط میکروسکوپ الکترونی
Background and Aims: Marginal seal in class V cavity and determination of the best restorative material in reducing microleakage is of great concern in operative dentistry. The aim of this study was to evaluate the effect of load cycling on the microleakage of low shrinkage composites compared with methacrylate-based composites with low shirinkage rate in class V cavity preparation. Marginal in...
متن کاملMicroleakage of Silorane-based Resin Composite in Comparison with Methacrylate-based Composite in Class II
Introduction: This in vitro study aimed to evaluate the effect of different monomer systems on microleakage in class II composite open sandwich restorations with and without a separating agent placed between the nanofilled resin modified glass ionomer and the resin. Materials and methods: Class II cavity preparations were prepared in maxillary premolars (n = 240) and the cervical limit of the p...
