Antibacterial activity of fluoride release sealants on mutans streptococci.

This study was conducted to study the antibacterial activity of sealants on mutans streptococci. The antibacterial effect of fluoride release sealants was estimated by using agar plates infected with several strains of S. mutans and S. sobrinus. Both bacterial groups were sensitive to sealant antibacterial activity, there was not statistical difference in the inhibition between both groups. The Teethmate-F was the only active material in this study and showed more than four times fluoride release than FluoroShield. The inhibition activity was associated with sealant fluoride release after the setting of this material.
