title: Mouthrinses affect color stability of composite.
abstract: OBJECTIVE
  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.
  
  
  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).
  
  
  CONCLUSIONS
  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.
