Influence of amine fluoride/stannous fluoride mouthwashes with and without chlorhexidine on secretion of proinflammatory molecules by peri-implant crevicular fluid cells.

Aim: Patients with dental implants need optimal plaque control. Peri-implantitis is an inflammation of soft and hard tissues around implants characterized by bone loss mediated by proinflammatory molecules such as IL-1beta, PGE(2), vascular endothelial growth factor (VEGF). The aim of this study was to evaluate the influence of amine fluoride/stannous fluoride (AmF-SnF(2)) vs chlorhexidine 0.12% (CHX) combined with Am-SnF(2) on IL-1beta, PGE(2) and EGF secretion by cells of crevicular peri-implant fluid.

Methods: Thirty patients with dental implants were included in this study. The test group used AmF-SnF(2) rinsing for 14 days, the control group used CHX rinsing during the first 7 days and AmF-SnF(2) during the following 7 days. Crevicular samples were collected using filter paper strips and assayed for level of IL-1beta, PGE(2) and VEGF with ELISA test. Data were analyzed with paired and unpaired t test.

Results: IL-1beta, VEGF and PGE(2) levels were significantly lower in test compared to control group. Comparing first with second week of treatment, a greater decrease of IL-1beta and VEGF was evident in sample group during the second week. There was a lower decrease of IL-1beta and VEGF during the entire treatment in control group. Differences of PGE(2) levels after 7 days in both the groups were not significant while there was a significant difference during the second week.

Conclusion: The following data suggest that the use of AmF-SnF(2) could decrease the production of IL-1beta, PGE(2) and VEGF by inflammatory cells.AmF-SnF(2) could be an alternative to CHX mouth rinses in plaque control of patients with implants.
