Biodent tooth varnish
Increases resistance to unfavourable bacteria on teeth
Oral bacteria and dental plaque have a protective effect. Dental plaque protects against wear and contains substances that strengthen the enamel. But bacteria in the mouth can also be unfavourable. Eating lots of sugar and brushing poorly leads to increased unfavourable bacteria that produce saccharic acid.
Chlorhexidine dental varnish can be used to increase resistance to unfavourable bacteria on the teeth. The best known varnish with a high percentage of chlorhexidine for this purpose is EC40. This product was placed on the market by Explore Multidisciplinary research group consisting of M.J.M. Schaeken and J.S. van der Hoeven. Now, Biodent BV produces and sells EC40 with 20% chlorhexidine diacetate and BioC with 10% chlorhexidine.
Studies into the effect of these chlorhexidine varnishes showed that a product with ethanol and sandarac also has an effect against unfavourable bacteria. Sandarac is one of the additives in Biodent's chlorhexidine varnishes. It is a resin made by conifers of the cypress family to protect themselves against bacteria and fungi. So, we also now offer Biodent Sandarac, a tooth varnish without chlorhexidine. For the effects of Biodent’s varnishes, see the graph below.
After one week’s use of Biodent Sandarac, people with more than 1,000,000 saccharic acid bacteria on their teeth only had some 1,000 of these bacteria. Additionally, 20% of the molars were still entirely free of these bacteria. Using Biodent tooth varnish supports healthy bacterial flora on the teeth. Products with chlorhexidine have a stronger effect; see the graph above.
