title: [The caries-protective efficacy of 2 fluoride varnishes in a 2-year controlled clinical trial].
abstract: The aim of this randomized, double-blind study was to measure the cariostatic effect of Bifluorid 12 (VOCO GmbH), containing 6% sodium fluoride and 6% calcium fluoride and Laweflour-Schüttellack (LAW), containing 5% sodium fluoride in comparing of placebo varnish. The caries study included 400 schoolchildren, aged 12-14 years. The tests according to the DMFS were carried out by two independent examiners. The 400 children were divided into 3 test and 1 placebo group, each group consisting of 100 subjects. After two years there was a significant inhibition of caries increment in all test groups compared to placebo group. Percentage caries reduction ranged from 25 to 30%. The highest effect was stated at proximal surfaces.
