Objective: To compare the levels of fluoride ion retention in saliva over 24hr period following use of fluoridated dentifrice, fluoridated mouth rinse and their combination. Methodology: A single blinded study consists of 10 volunteers aged 18-25yrs having DMFT = 0-1 were randomly selected and subjected to four experimental groups. Group I - Nonfluoridated dentifrice (NFD) Group II - Fluoridated dentifrice 1000ppm (FD) Group III - Nonfluoridated dentifrice and 0.05% sodium fluoride mouth rinse (NFD + FR) Group IV - Fluoridated dentifrice 1000ppm and 0.05%sodium fluoride mouth rinse (FD+FR).Participants were provided with nonfluoridated dentifrice to brush their teeth for one week prior and during the study. On the day of study, saliva samples were collected prior to brushing or rinsing, immediately(0 min), 15min,30min,1hr,2hr,8hr, 15hr after brushing or rinsing and 24hrs samples were collected next day morning before brushing or rinsing. Results: Nonfluoridated dentifrice and fluoridated rinse group showed highly significance in retention of fluoride ion concentration at different intervals of time compared to NFD, FD groups. FD + FR group showed highly significant difference in retention of fluoride ion concentration at different intervals of time compared to FD group. There was no statistical significance was there in retention of fluoride ion concentration in saliva among NFD + FR group and FD + FR. Conclusion: Fluoride retention was equally effective in FD + FR and NFD + FR groups. Fluoride rinse was more effective way of delivering topical fluoride than fluoride dentifrice. Use of fluoride at bed time resulted in longer retention than daytime application.
