Abstract

Objectives: The purpose of this study was to evaluate the effect of chlorhexidine and essential oils containing mouth rinses on oral wound healing after periodontal flap surgery. Materials and methods: Eighty subjects participated in the study and were randomly assigned to use water, 0.12% chlorhexidine (CHX), essential oils (EO), 5% CHX, and 10% EO. Subjects were examined at 1, 2, and 3 weeks postoperatively. Plaque index (PI) and the modified gingival index (GI) were recorded, while wound epithelialization was measured to evaluate the healing process. Numerical data were analyzed with parametric test for multiple comparisons (ANOVA) with Bonferroni correction. Categorical data were analyzed using Chi-square test/fisher exact test. Results: All groups demonstrated a gradual GI reduction from first to third visit. Patients in the CHX group presented statistically significant lower PI scores than patients in the water group at the all-time points of the study. Wound epithelialization analysis demonstrated that 100% of the sites in the CHX group were healing by secondary intention at visit 1. This finding was statistically significant. Conclusion: Full strength concentrations of CHX and EO did not show any detrimental effects on healing after traditional periodontal surgery at the end of the observation period. Clinical relevance: The use of chlorhexidine and EO containing mouthwashes does not appear to delay wound healing. Diluting these commercial mouthwashes may present an approach that could possibly reduce the adverse effects (such as tooth staining) associated with their use, while maintaining their antibacterial properties.
