| Popis: | Background: Clinical studies on the caries-preventive properties of chlorhexidine mouthrinses are limited and the results are inconclusive. Aim: The aim of this study was to elucidate the contribution of a 0.2% chlorhexidine mouthrinse to the protection of enamel and dentine against demineralization. Methods: In this randomized two-treatment, two-leg study 14 individuals wearing partial prostheses were enrolled. Sound enamel and dentine specimens were placed in situ for 4 weeks. Twice daily, a mouthrinse was performed with either chlorhexidine or saline (control) depending on the experimental group the participant was allocated to. After the experimental period, plaque samples were collected from the surface of the specimens and from natural tooth surfaces to assess the organic acid production upon a sucrose challenge. The specimens were analyzed for mineral loss by transversal microradiography. Results: This study could not demonstrate a significantly better protection of enamel and dentine against demineralization by the chlorhexidine treatment compared to saline. No differences in acid production of plaque samples from the chlorhexidine-treated and control groups were observed. This result was also found for plaque samples originating from the natural tooth surfaces. Conclusion: Mouth rinsing with 0.2% chlorhexidine did not prevent demineralization of dentine and enamel in situ. |
