OBJECTIVE

The aim of this study was to evaluate the effectiveness of hyaluronic acid and chlorhexidine mouthwash in the treatment of peri-implant mucositis.

MATERIAL AND METHODS

Clinical and microbiological studies were conducted before and 14 days, 1, 3 and 6 months after the periodontal treatment in 46 patients (144 implants with fixed dentures) with peri-implant mucositis. The patients were divided into 3 groups: test, comparison and control. Basic periodontal therapy in all groups included professional cleaning and individual oral hygiene training. Test group (15 patients) received basic periodontal therapy plus 0.20% chlorhexidine with hyaluronic acid mouthwash, the comparison group (15 patients) — basic periodontal therapy +0.05% chlorhexidine mouthwash. In control group (16 patients), treatment was limited to basic periodontal therapy only.

RESULTS

At the initial stages of observations, there was a statistically significant improvement in the clinical indices in all treatment groups (p<0.001). The use of 0.20% chlorhexidine with hyaluronic acid mouthwash revealed a higher quality of treatment. After 6 months of observation, the clinical features in patients of the control group was almost similar to the state before treatment. The patients of the test group had a more pronounced elimination of facultative and periodontal pathogens in comparison with other groups.

CONCLUSION

The use of 0.20% chlorhexidine with hyaluronic acid containing mouthwash allows the clinician to achieve a better results in the treatment of peri-implant mucositis. The evaluation the oral microflora in patients with peri-implant mucositis can be used as a prognostic criterion for the outcomes of rehabilitation.
