An in-vitro analysis of the staining effect of different chemical mouthwashes

Aim: To evaluate the staining potential of three commercially available types of mouthwashes. Materials and Methodology: Sixty extracted maxillary central incisor teeth were used for the study. The teeth were divided into three groups (N=30). Teeth were immersed in three different mouthwash solutions for 2 months. The color change was measured with a spectrophotometer before immersion in solution (baseline) and after 2 months. L*a*b* values were used to calculate color changes (ΔE). Statistical analysis was done using ANOVA test and Paired T-test. Results: Greater staining was caused by Listerine and Chlorhexidine mouth was has compared to Chlorhexidine mouthwash with ADS after 2months. Conclusion: Chlorhexidine mouthwash with ADS is a better choice as a mouthwash to minimize tooth staining.
