Abstract :DOI : 10.26650/eor.2018.35588 Purpose The present study aimed to evaluate the color stability of provisional restorative materials stored in different mouth rinses and green tea extract for 14 days. Materials and methods Forty cylinders of fixed provisional restoration material of 15-mm diameter and 2-mm thickness were prepared. The samples were separated into four storage solutions insert ignore into journalissuearticles values(three different mouth rinses and green tea); insert ignore into journalissuearticles values(n=10);. The values of L*, a*, and b* were determined before and after storage in the solutions using a spectrophotometer, and the ΔE* value was calculated. The effect of mouth rinses and green tea extract on the color change of provisional restoration materials was determined with one -way analyses of variance. The Tamhane multiple comparison analysis was used to determine the differences between the groups insert ignore into journalissuearticles values(p<0.05);. Results The color stability of the provisional restoration materials varies depending on the solution. Listerine mouth rinse showed more color change than Sensodyne or Colgate did. Minimal color change was found in the green tea solution. Conclusion The effect of mouth rinses on the color stability of fixed temporary restorative materials is remarkable. As green tea shows less color change, it can be suggested as an alternative to mouth rinses.
