The effect of an alexidine mouthwash on dental plaque and gingivitis

The alexidine mouthrinse used in this study (CP-101) is effective in reducing plaque. There was a reduction in gingivitis after 6-months use but not at a statistically significant level. An extrinsic brown stain occurred at a significant level on the teeth of participants using the active mouthrinse. Blood and urine laboratory results indicated that alexidine can be safely used over a 6-month period.
