Scientific evidence

The following figures demonstrate the loss of dental hard tissue in enamel and dentine samples from an in situ study (Ganss et al. 2010).

Methods:
  • Half of each sample was shielded off with a light-curing resin and served as the reference area, while the other half was exposed to acid.
  • The samples were carried in the oral cavity for 7 days, during this time they were exposed to erosive challenges 6 x 5 minutes a day. A placebo rinse or elmex® EROSION PROTECTION dental rinse was used (10 ml for 30 s) once daily.
Results:
  • In all the images, the step indicates the border between reference and the exposed area. Repeated highly erosive acid attacks cause major loss of dental hard tissue in the placebo-group samples.
  • The samples treated with elmex® EROSION PROTECTION dental rinse only display minor loss of dental hard tissue.
  • The low-soluble stannous compounds integrated into the enamel significantly inhibit dental hard tissue loss in samples carried in the oral cavity.

Conclusion:
  • These results clearly demonstrate the protective effect of elmex® EROSION PROTECTION dental rinse against erosive dental hard tissue loss.
elmex® EROSION PROTECTION dental rinse makes enamel and dentine more resistant to erosive acid attack
