Back Ground and Objectives: Fluoride has been the corner stone and integral part of the preventive programs worldwide. The present study was undertaken with the objective to assess caries preventive effect, feasibility and cost of fluoride varnish and fluoride mouth rinse programs for preventing dental caries. Methods: 228 children in age group of 12 to 14 year were selected and are randomized in to three groups. Group 1 (77 children)-receiving fluoride varnish and placebo mouth rinse, Group 2 (75 children) - receiving fluoride mouth rinse and placebo varnish and Group 3 (76 children) - Control group. A double blind design was adopted. Caries diagnostic criteria given by Nyvad and Colleagues (1999) was adopted and caries was diagnosed clinically at both cavitated and non-cavitated lesion at 6 months, 12months and 18 months. Results: Fluoride varnish has an efficacy value of 33.26% where as efficacy of mouth rinse is 31.51% along with an increment of 13.7%DMFS in control group at the end of 18 months. A total of 66.86% (113/169) initial lesions in the varnish group and 66.25% (108/163) of the lesions in mouth rinse group healed at eighteen months compared to baseline. A total of 1.46 and 1.44 surfaces are saved per child in terms of noncavitated lesions at 18 months. There is substantial saving of costs in varnish group i.e four times than the conventional restorative treatment. Interpretation and Conclusion: Fluoride varnish and fluoride varnish are effective practical, feasible and cost saving procedures at primary health care level in school settings.
