ABSTRACT
Background: Fluoride content in saliva and dental plaque plays a key role in the prevention and control of dental caries. Fluoride varnish adheres to the tooth surface for longer period and prevents its immediate loss, thus acting as slow-releasing reservoirs.
Aim: to evaluate the effect of different fluoride varnishes forms on the level of fluoride ions in saliva and their antibacterial action on streptococcus mutans.
Materials and methods: Seventy five school children of age 12-15 years were selected fulfilling inclusion and exclusion criteria and divided into three groups: Group I (Duraphat varnish); Group II (Bifluorid 10) ; Group III (MI varnish). Salivary samples were collected and fluoride ions were recorded at baseline, one, two, 24,48 hours after applications. Salivary streptococcus mutans(CFUs X 10 6) was assessed at baseline and after one, two, three, and four weeks of applications.
Results: Statistical significant higher mean values of fluoride ions Group II (Bifluorid 10); Group III (MI varnish) after one, two, 24, 48 hours of applications. Statistical significant reduction was detected in the streptococcus mutans level with the three used varnishes with different levels.
Conclusion: After 48hrs of fluoride varnishes application, (MI varnish)fluoride varnish with CPP-ACP was superior to other varnishes to maintain high level of salivary fluoride ions. Fluoride varnish with CPP-ACP and Bifluorid 10 varnishes keep the saliva with low level of cariogenic streptococcus mutans after four weeks of application.
