Comparison of the repairing effect of fluoride on experimentally produced white spot lesions on healthy teeth inudsingle and repeated applications.

摘要

The aim of this research was to test the repairing effect of “fluoride varnish-Duraphat” onuddemineralization of tooth in single and repeated applications.udMy question was “What is the difference between single and repeated applications of fluorideudagent (Duraphat varnish) on demineralized tooth surface?”udIt was hypothesized that “ There would be a significant difference in the means of repairingudeffect of fluoride on demineralized tooth after repeated applications”. To test the research questionudand the hypothesis, experiments were conducted. The method used was taking the demineralizedudtooth and apply a fluoride-varnish and note down the difference in demineralization after single andudrepeated applications. For this, demineralization was produced experimentally by applying %37udPhosphoric acid on the surface of extracted healthy tooth. Then Duraphat solution which isudintroduced as an effective fluoride varnish agent was applied as single(which is claimed that it has aud%77 percent effect) and repeated applications (two times by weekly interval) on demineralized toothudsurface and the demineralization level on tooth was measured by a professional dental device calledudDIAGNOdent for each experiment stage.udThe results of the experiment was analyzed with the appropriate statistical test, it was seenudthat there was a significant difference between the means of the beginning and the acid application,udbeginning and the first fluoride application. However, there was no significant difference between theudmeans of the beginning and the Duraphat Varnish’s second application. At the end of the research,udthe hypothesis was accepted as fluoride varnish has repairing effect on demineralized tooth providedudthat this feature is gained by at least two applications.
