- Abstract
Background and Aims: Since recurrent caries are one of the major causes of failure in resin restorations, the production of antibacterial resin composites was always under investigation. The aim of this study is evaluating the efficacy of fissure sealants containing nanosilver particles against the Streptococcus mutans. Materials and Methods: In this experimental study the antibacterial properties of two non fluoride & fluoride containing sealants resins incorporating 0, 0.01, 0.02 , 0.03 , 0.04 ,0.05% w/w of nano silver was investigated using direct contact test. Sealants formed on the walls of 500ml microtube and after curing, they left in contact with bacterial suspension. In times of 3, 24, 48h, a 10 μl volume of liquid medium was placed in blood agar culture and after 24 h incubation at 37°C, the number S.mutans colony was counted by colony counter. Results: Results reported fluoride containing sealants comparing to non fluoride ones had significant effect on inhibition of S.mutans growth (P<0.05). The direct contact test demonstrates that by increasing the amount of nano particles, the bacterial growth has been significantly diminished (P<0.001). Conclusion: While fluoride containing sealants demonstrate antibacterial effect but in sealants with incorporation higher weight percentage of silver nano particle, this effect been masked and nano particle have got stronger and more significant antibacterial effect in direct contact test.
