Aim: The aim of this study was to assess color changes in teeth and two different composite resins under the influence of chlorhexidine (CHX) with and without anti-discoloration system (ADS). Materials and Methods: A total of 20 extracted human premolar teeth for periodontal and orthodontic purposes were selected for the study. Further, a total of 40 composite specimens comprising 20 each nanoceramic and nanohybrid composite disks of size 10-mm diameter and 0.5-mm thickness were prepared on a customized model for standardization using the composite filling instrument. The specimens were cured with light-curing unit for 20 s and polished with a composite polishing kit. Two mouthrinses comprising CHX and CHX with ADS were used. Baseline color values of natural tooth and two composite resins were recorded using an ultraviolet spectrophotometer. After baseline spectrophotometric measurements, all the samples were subjected to the mouthrinses. The postimmersion color values of the samples were then recorded, respectively, using the same spectrophotometer. Statistical Analysis Used: The statistical analysis was done using paired t-test. Results: Reflectance values showed a statistically significant difference between CHX and CHX with ADS among nanoceramic and nanohybrid composite samples. There was no statistically significant difference in reflectance values among natural teeth samples with either CHX or CHX with ADS. Conclusion: Within the limitations of the current study, CHX with ADS may aid in avoiding stains caused due to use of CHX mouthwash, thereby making it more acceptable for patients.
