Effect of immersion in different media on the mechanical properties of dental composite resins

AUTHOR(S): Rafid M Al Badr and Harth A Hassan
ABSTRACT:This article was undertaken to investigate the effect of various media and storage time on the mechanical properties of dental composites resins. Three dental composite resins Competence universal, Spectrum and Bright light were tested. Forty-eight Specimens of each composites were prepared for flexural strength and Forty-eight Specimens of each composites were prepared for diametral tensile strength. The specimens were storage in Different solutions: distilled water, artificial saliva, ethanol/water and mouthwash at 37°C, after that; flexural strength (FS) and diametral tensile strength (DTS) tests were measured on 24 hours, 15, 30, 60 and 90 days. The time immersion and the solutions have effect on the flexural strength and modulus and on DTS, all composites exhibited lowest mechanical properties at 90 days. Composite spectrum has highest mechanical properties, the flexural strength ranged from 99.1 to 44.84 MPa when composites immersion in ethanol/water. While composite Bright light recorded lowest properties.
