Plain Chlorhexidine Works Better Than Chlorhexidine With an Anti-Discoloration System
Journal of Clinical Periodontology, 11th Nov 2020
 CHX has well-documented plaque-inhibiting effects and is used as a compensatory biocide for abstention of mechanical toothbrushing after periodontal surgery.
 Since the main side effect of CHX is tooth staining, this study was undertaken to determine whether CHX + ADS could maintain the plaque- inhibiting capacity of CHX while reducing tooth staining.
 Based on the results, the authors concluded that 0.2% CHX + ADS was less effective in preventing plaque and gingivitis.
 While 0.2% CHX + ADS produced significantly less tooth staining and mucosal discomfort, patients did not show a preference for either product.
 The authors concluded that “CHX-only” is the treatment of choice due to its superior plaque-inhibiting properties.
