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 (three different mouth
rinses and green tea) (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 (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.
