Share Abstract:

Color stability of restorative resins

Khokhar/Razzoog/Yaman

Pages: 733-737
PMID: 1946950

The purpose of the present study was to evaluate the color stability of selected indirect composite ersins. Twenty-six specimens each of Dentocolor, VisioGem, Brilliant D. I., and Concept were fabricated and immersed in chlorhexidine, coffee, and tea. The modifying effect of saliva on staining was also studied. Coffee and tea both stained the tested materials, but tea stained more than coffee. The addition of chlorhexidine and saliva increased staining when used with tea. Most staining was superficial and could be removed with regular oral hygiene; however, residual staining, which might become cumulative, was recorded. Brilliant D. I. samples exhibited the most discoloration and Concept samples the least.
