A New Customized Bioactive Glass Filler to Functionalize Resin Composites: Acid-Neutralizing Capability, Degree of Conversion, and Apatite Precipitation

Shrinkage behaviour of flowable resin-composites related to conversion and filler-fraction.

OBJECTIVES To evaluate the shrinkage-strain, degree of conversion (DC) and percent filler of a range of flowable resin-composites. METHODS Several commercially available flowable resin-composites were selected. The bonded-disk technique was used to measure shrinkage-strain kinetics. Measurements were obtained continuously for 60min by irradiation for 40s at 750mW/cm(2) at two initial temperat...

Correlation of filler content and elastic properties of resin-composites.

OBJECTIVES The aim was to determine the Young's modulus (E), bulk modulus (B), shear modulus (G) and Poisson's ratio (nu) of a series of composite restorative materials and to correlate them with their filler volume-fractions. METHODS Twelve model resin-composite formulations, with systematically varied volume-fraction (Tokuyama), a flowable resin-composite (Point 4 flowable, Kerr) and two hy...

Inorganic and Prepolymerized Filler Content Analysis of Four Resin Composites

A Comparative Study of the Solubility and Sorption Properties of Resin Modified Glass Ionomer and a Bioactive Liner

Background and Aim: This study aimed to compare the sorption and solubility properties of ACTIVA BioACTIVE liner and resin modified glass ionomer (RMGI).   Materials and Methods: In this in vitro study, a total of 30 samples were fabricated from each liner measuring 15 mm in diameter and 1 mm in thickness according to ISO 2009:4049. They were then divided into 6 subgroups (n=5) to assess th...

Effect of filler size and filler loading on wear of experimental flowable resin composites

The relationship between wear resistance and filler size or filler loading was clarified for the universal resin composite; however, their relationship in flowable resin composites has not been clarified. The purpose of this study was to investigate the effect of filler size and filler loading on wear of experimental flowable resin composites by using a cyclic loading device. Nine experimental ...
