evaluation 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 کاملMicroleakage in Class V Cavities Restored with Sandwich Technique: Self-Etch versus Total-Etch Bonding Systems
Objective: Microleakage has always been a problem in restorative dentistry. To decrease microleakage, modern bonding systems, different application methods and sandwich technique have been recommended. The purpose of this study was to assess the microleakage in class V cavities restored with open sandwich technique using self-etch and total-etch bonding systems. Methods: In this in vitro st...
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...
متن کاملThe 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 کاملEffect of thermocycling and varying polymerization techniques on the restorative interface of class V cavities restored with different composite resin systems
BACKGROUND To evaluate marginal microleakage of two composite resins - a methacrylate- and a silorane-based submitted to different polymerization techniques and thermocycling. MATERIAL AND METHODS Ninety-six class V cavities were prepared in sound human molars and restored under different polymerization and thermocycling regimens. The adhesive systems employed were Adper Scotchbond Multipurpo...
