Antimicrobial effect of three recently developed restorative materials against streptococcus mutans and lactobacillus casei - an in-vitro study

Objective : The aim of the study was to determine the antibacterial efficacy of three different restorative materials against Streptococcus mutans and Lactobacillus casei. Materials and methods : In the present study agar well diffusion method was applied to evaluate and compare antimicrobial efficacy of Fuji IX (GC Tokyo,Japan), Hi-dense (Shofu Inc,Kyoto,Japan) and Beautifil II (Shofu Inc,Kyoto,Japan) against Streptococcus mutans and Lactobacillus casei. Zone of inhibition was measured after at different time intervals that is 24hr,48hr,72hr and 7th day. Results: Hi-dense  restorative material demonstrated the best antimicrobial efficacy  against Streptococcus mutans followed by Fuji IX and Beautifil II. Most effective antibacterial  restorative material  against Lactobacillus casei was Fuji IX. Conclusion: All the tested restorative materials in present study demonstrated significant antimicrobial efficacy Key words: Antibacterial activity, Beautifil II, Fuji IX, Hi-Dense, Lactobacillus casei, Streptococcus mutans
