Introduction: Many studies were done about effect of varnishes on reducing of mocroleakage in amalgam restorations. Fluoride – containing varnishes often use for treatment of dentin hypersensivity from cervical erosive lesions, and for fluoride therapy instead of fluoride containing mouthwashes and gels. Usually, this type of varnishes isn't used as cavity varnishes. Objective: In this research, we used fluoride – containing varnishes (Fluoroprotector) as cavity varnishes and compare its microleakage with Simia teb, Harvard and Pishro varnishes. Materials & Methods: Thirty enrooted human sound human premolars were used and divided to 5 experimental groups. In 4 groups, we used 4 type of above varnishes and in 5th group or control group no varnish was used Class V cavity with 3*2*1.5mm was prepared on buccal and lingual surfaces of each tooth, and terminate the number of cases were 60. Cavities were filled with amalgam, and then put in termocycler devise. Finally, sections with buccolingual dimension were prepared. The microleakages in occlusal and gingival walls of restorative cavities were studies. Results: The results of this study showed that Pishro and Fluoroprotector Varnishes have better rate of microleakage than other groups in occlusal and gingival walls.
