Cytotoxicity and cytokine expression induced by silorane and methacrylate-based composite resins
OBJECTIVE The aim of this study was to evaluate cytotoxicity and cytokine production induced by light-cured or non-light-cured methacrylate-based and silorane composite resins in RAW 264.7 macrophages. MATERIAL AND METHODS Cells were stimulated with the extracts from light-cured or non-light-cured composite resins. After incubation for 24 h, cytotoxicity was assessed with the lactate dehydrog...
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...
متن کاملComparison of silorane and methacrylate-based composite resins on the curing light transmission.
The aim of this study was to investigate the influence of different composite resins - Filtek P90 (silorane-based composite) and Heliomolar (methacrylate-based composite) - on light transmission and decrease in Knoop hardness between the bottom and top of cured specimens. The irradiance of a light-curing unit (LCU) was measured with a power meter (Ophir Optronics; 900 mw/cm2) and spectral distr...
متن کاملEffect of Accelerated Artificial Aging on Translucency of Methacrylate and Silorane-Based Composite Resins
OBJECTIVES Composite restorations must have tooth-like optical properties namely color and translucency and maintain them for a long time. This study aimed to compare the effect of accelerated artificial aging (AAA) on the translucency of three methacrylate-based composites (Filtek Z250, Filtek Z250XT and Filtek Z350XT) and one silorane-based composite resin (Filtek P90). MATERIALS AND METHOD...
متن کاملEffect of water storage on flexural strength of silorane and methacrylate-based composite resins
Objectives This study assessed the effect of water storage on the flexural strength (FS) of low shrinkage composites. Materials and Methods A total of 165 bar-shaped specimens (2 × 2 × 25 mm) were fabricated of 2 low shrinkage composites (Filtek P90 [3M ESPE], GC Kalore [GC International]) and a conventional methacrylate-based composite (Filtek Z250 [3M ESPE]). The specimens were subjected to...
