Fluoride content and uptake in sound enamel after the usage of Persica & Irsha in comparison with standard Oral-B mouthwash

Regarding to increasing fluoride consumption by patients and increasing currency of different kinds of mouthwashes like Persica and Irsha that claim to have fluoride, the aim of this study was to determine fluoride content and uptake in sound enamel after usage of Iranian mouthwashes in comparison with standard oral-B mouthwash. Methods & Materials: In this in vitro experimental study, the fluoride content of mouthwashes were determined. Then 30 extracted human sound premolars were randomly divided into three groups of 10 and each tooth was longitudinally bisected into experimental and control halves. A specified hemi circular area on each experimental half was treated with one of the rinses. Three case-control groups were evaluated after using Oral-B, Irsha and Irsha with brushing. The amount of fluoride uptake in enamel surface (KOH - Soluble fluoride) and structure (structurally bound fluoride) was determined by the method of Caslavska and Mc Cann. The results were analyzed by using paired t, ANOVA and LSD tests. Persica didnt have any considerable fluoride but Irsha was found to have the same amount of fluoride as Oral-B (0.05% NaF). There was a statistical difference between experimental and control halves in fluoride content (P<0.05). But there was no significant difference between three groups in fluoride uptake. Persica did not have any considerable fluoride. There is no difference between structurally bound fluoride uptake after using Irsha with or with out brushing. But it decreased the amount of KOH-Soluble Fluoride.
