Abstract
This study was carried out in order to assess the clinical and microbiological efficacy of the two specific caries prevention programs (P1 and P2) as compared to the control group (C). Two supragingival plaque samples were collected and analysed qualitatively and quantitavitely by the "checkerboard" DNA-DNA hybridization method, for 10 different oral species. The results showed that the two caries prevention programs demonstrated their efficacy in the substantial reduction of DMFT scores and DMFS scores after six years of application. The mouthrinsing program combined with pits-and-fissure sealant (P2) was superior to fluoride mouthrinsing alone (P1) and almost prevented all caries. There was a significant statistical positive correlation between the levels of S. mutans and S. sobrinus and the prevalence of dental caries.
