Microleakage 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...
متن کاملComparison of resin composite restorations microleakage: An in-vitro study
The aim of this study was to compare the microleakage of total-etch and self-etch adhesives by three methods including dye extraction, dye penetration and fluid filtration with determining the correlation value among these techniques. Seventy-two premolar teeth were selected for this in vitro study and Class 5 cavities were prepared on the buccal surface of these at the cemento-enamel junction ...
متن کاملMicroleakage evaluation of silorane based composite versus methacrylate based composite
AIM Our study aimed to analyze the microleakage of silorane-based composite in comparison to two homologous methacrylate-based composites. MATERIALS AND METHODS Standardized class I cavities (4 × 2.5 × 3 mm) were prepared on extracted human premolars and randomly assigned into three groups (N = 15) as follows: Group A, Filtek P90 (silorane) with its dedicated adhesive system (P90 system adhes...
متن کاملMicroleakage of nanofilled resin-modified glass-ionomer/silorane- or methacrylate-based composite sandwich Class II restoration: effect of simultaneous bonding.
OBJECTIVES Microleakage of composite restorations at the cervical margin placed apically to the cementoenamel junction (CEJ) is still a concern. This study evaluated the effect of simultaneous bonding application on cervical sealing of nano-ionomer/silorane- or methacrylate-based composite open sandwich Class II restorations in the modified technique compared with that of conventional bonding. ...
متن کاملمقایسهی میزان ریزنشت حفرات کلاس II ترمیم شده با کامپوزیت‌های سایلوران و متاکریلات بیس با استفاده از دوروش مختلف ترمیمی (روش ساندویچ باز، باندینگ)
Background and Objective: Polymerization shrinkage in composite resins is responsible for microleakage restoration. A recently introduced composite resin Filtek P90 is based on siloxanes and oxiranes which polymerize by cationic "ring opening" polymerization resulting in reduced polymerization shrinkage. The aim of this study was comparative evaluation of microleakage in class II cavities resto...
