Comparison of the Efficacy and Side Effects of Chlorhexidine Mouthrinses with (Hexidine) and without (Epimax) Alcohol

Abstract

Introduction: Chlorhexidine mouthrinses have widely been recognized for their contribution in maintaining plaque control. Most of them contain alcohol that makes them impractical for many patients. Alcohol-free mouthwashes may have fewer side effects but may be less efficient. The current study was aimed to compare the effectiveness and side effects of chlorhexidine mouthrinses with and without alcohol. Materials and Methods: In this double-blind clinical trial, 32 patients with moderate and severe gingivitis were recruited. For all patients, full prophylactic procedures, such as removal of plaque, calculus, and stains on the teeth, were performed. Each patient was asked to use 15 mL of the mouthrinse for 60 s twice daily. The patients were divided into two groups, one group used Hexidine (0.12 chlorhexidine and 10 ethanol) mouthwash and the other group used Epimax (0.12 chlorhexidine and 0.05 sodium fluoride) mouthwash. After 14 days, plaque (PI), gingival (GI), and stain indices were analyzed. The obtained data were analyzed by using SPSS 16 using covariance Analysis of covariance (ANCOVA) and t-test. Results: Both mouthwashes significantly reduced the mean scores of plaque (P < 0.0001) and gingival (P < 0.032) indices after 2 weeks; however, Hexidine mouthrinse was shown to be more effective. The extent of stain was the comparable in both groups. While Epimax mouthrinse caused severe stains on the teeth, Hexidine mouthrinse caused burning mouth. Conclusion: Although Epimax mouthwash did not show any side effects, it was less suitable and caused more dental stain. Ethanol-free Hexidine mouthwash seems to be more proper for gingivitis, but its side effects are required to be taken into consideration. © 2016 Dental Hypotheses | Published by Wolters Kluwer - Medknow.
