Abstract

Background and Objectives: The most prevalent and worldwide oral disease is DENTAL CARIES that affects a significant proportion of the world population. There are some classical approaches for control, prevention and treatment of this pathologic condition; however, the results are still not completely successful. Therefore new methods are needed for better management of this important challenge. CHITOSAN is a natural and non-toxic polysaccharide with many biological applications, particularly as an antimicrobial agent. CHITOSAN nanoparticle is a bioactive and environment friendly material with unique physicochemical properties. The aim of the present study was to investigate the antimicrobial effect of CHITOSAN and nano-CHITOSAN on the most important cariogenic streptococci.Materials and Methods: For evaluation of antimicrobial effect of CHITOSAN and nano-CHITOSAN against ORAL STREPTOCOCCI broth micro-dilution method was carried out for four bacterial species; Streptococcus mutans, Streptococcus sobrinus, Streptococcus sanguis and Streptococcus salivarius. Also the effect of these materials on adhesion of above bacteria was evaluated. One-way ANOVA and post hoc Tukey test were used for statistical analysis. Results: The MICs of CHITOSAN for S. mutans, S. sanguis, S. salivarius and S. sobrinus were 1.25, 1.25, 0.625 and 0.625 mg/mL, respectively. The MIC of CHITOSAN nanoparticle for S. mutans, S. salivarius and S. sobrinus was 0.625 mg/mL and for S. sanguis was 0.312 mg/mL. CHITOSAN and CHITOSAN nanoparticles at a concentration of 5 mg/mL also reduced biofilm formation of S. mutans up to 92.5% and 93.4%, respectively.Conclusion: The results of this study supported the use of CHITOSAN and CHITOSAN nanoparticles as antimicrobial agents against cariogenic Streptococci.
