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...

The objective of this in vitro study was to assess the color change of resin nanocomposites exposed to a cola beverage at different times. Seventy-five cylinders (10 mm x 2 mm) were prepared from each of 4 resin-based composite materials, 3 nanocomposites (Filtek Supreme, Tetric EvoCeram, Premise) and 1 microhybrid (Filtek Z250), to give a total of 300 specimens. Specimens in each group were di...

This study evaluated the polymerization shrinkage, flexural and compressive properties of low-shrinkage resin composites. For the study, four methacrylate-based and one silorane-based resin composites were light cured using three different light-curing units (LCUs) and their polymerization shrinkage, flexural (strength (FS) and modulus (FM)) and compressive (strength (CS) and modulus (CM)) prop...

The aim of this study was to evaluate the microtensile bond strength of self-etch adhesive systems to dentin after storage in acids from oral biofilm. Three adhesive systems were used in the study: a two-step self-etch adhesive for use with a silorane-based resin composite (Filtek P90 adhesive system - P90), a two-step self-etch adhesive (Clearfil SE Bond - CSE) and a one-step self-etch adhesiv...

AIM This in vitro study evaluated the effect of different cavity disinfection agents on bond strength of a silorane-based resin composite. MATERIALS AND METHODS Thirty-six caries-free human third mandibular molars sectioned in mesio-distal direction were mounted in acrylic resin with their flat dentin surfaces exposed. After the dentin surfaces were wet ground with # 600 silicon carbide paper...

Aim: The aim of this study was to measure the radiopacity of seven flowable composite resins (FCRs). Methods: The radiopacity values of Tetric EvoFlow®A3 (Ivoclar Vivadent), PermaFlo®A1 (Ultradent), Filtek Supreme XT®A3 (3M ESPE), wave®A3 (SDI), StarFlow®A2 (Danville Materials), els flow®A3op (Saremco Dental AG) and SYNERGY Nano Formula®A2/B2 (Coltène Whaledent) were determined with reference t...

Objectives: The aim of this study was to evaluate the structural microporosity (MP) and marginal gap (MG) different flowable composite resins placed with instruments using micro-computed tomography (μCT). 
 Materials Methods: Standard Class II MOD cavities were prepared on 108 lower third molar teeth. Three resins; Filtek Bulk-fill, SDR Bulk-fill I-Flow conventional resin applied a sharp e...

OBJECTIVES Light-curing of resin-based materials (RBMs) increases the pulp chamber temperature, with detrimental effects on the vital pulp. This in vitro study compared the temperature rise under demineralized human tooth dentin during light-curing and the degrees of conversion (DCs) of three different RBMs using quartz tungsten halogen (QTH) and light-emitting diode (LED) units (LCUs).
