Introduction: Fluoride varnishes play a pivotal role in inhibition of dental caries by increasing remineralization.

Aim: To determine the longevity of fluoride release from 3 different fluoride varnishes over a period of time through salivary fluoride estimation.

Materials and Methods: Twenty four extracted human deciduous anterior teeth were divided into four groups, i.e., ClinproTM XT, Flouritop SR, Flourprotector and Control group. Fluoride varnishes were applied on 3mm x 3mm window on labial surface of the teeth and then the teeth were immersed and stored in artificial saliva. The concentration of fluoride in ppm was measured after 1 week, 1 month, 3 months and 6 months. Fluoride release at each time interval for different groups was statistically analyzed using ANOVA and Post Hoc Tukey’s test.

Results: Although all the fluoride varnishes released fluoride, with greatest release observed during 1st week by Fluoritop SR (66.92±16.30ppm), ClinproTM XT Varnish released consistently and substantially more fluoride than Fluoritop SR and Fluorprotector during 6 months analysis (p<0.05). Fluorprotector showed the lowest rate of F release among all the groups compared.

Conclusion: Over a period of 6 months ClinproTM XT Varnish released consistently and substantially more fluoride than other tested products.
