Aim:
The aim of this study is to evaluate the effect of alcohol and nonalcohol containing mouth rinses on the color stability of a nanofilled resin composite restorative material.
Materials And Methods:
A total of 120 samples of a nanofilled resin composite material (Tetric N-Ceram, Ivoclar Vivadent AG, FL-9494 Schaan/Liechtenstein) were prepared and immersed in distilled water for 24 h. Baseline color values were recorded using Color Spectrophotometer 3600d (Konica Minolta, Japan). Samples were then randomly distributed into six groups: Group I - distilled water (control group), Group II - Listerine, Group III - Eludril, Group IV - Phosflur, Group V - Amflor, and Group VI - Rexidin. The postimmersion color values of the samples were then recorded, respectively.
Results:
Significant reduction in the mean color value (before and after immersion) was observed in nonalcohol containing mouth rinses (P < 0.001).
Conclusion:
All mouthrinses tested in the present in-vitro study caused a color shift in the nanofilled resin composite restorative material, but the color shift was dependent on the material and the mouthrinse used. Group VI (Rexidin) showed maximum color change.
