Background- Topical fluorides in the form of toothpastes, mouthrinses, varnishes and gels are effective caries preventive interventions. Aim: To assess the availability of fluoride concentration in saliva following the use of fluoride mouthrinse and dentifrice. Methods: In this cross-over study, two agents were used in the same children. The first test agent was daily fluoride mouthrinse (0.05% NaF) and the second test agent was 1000 ppm monofluorophosphate (MFP) dentifrice. Comparison of fluoride concentration in saliva for the two test agents (mouthrinse and dentifrice) was carried out at 1 hours, 5 hours, 10 hours, and 20 hours. Results: Mean values for the fluoride concentration available in saliva for Mouthrinse at 1 hour, 10 hours and at 20 hours were 0.38±0.356, 0.14±0.084 and 0.13±0.053 whereas mean values for Dentifrice were 0.31±0.264, 0.17±0.045 and 0.15±0.047. Significant difference was observed between the two test agents at 1 hour, 10 hours and 20 hours. Mean values for the fluoride concentration available in saliva for Mouthrinse at baseline and at 5 hours were 0.031±0.028 and 0.20±0.140 whereas mean values for Dentifrice were 0.032±0.019 and 0.19±0.067. It was observed that there is no significant difference between the two test agents at baseline and 5 hours. Conclusion: After use of NaF (0.05%) daily mouthrinse and MFP dentifrice (1000 ppm) the fluoride concentration in saliva continued high up to 20 hrs postuse.
