In Vitro Comparison of the effect of Nano-hybrid composite resin and Amalgam on the adhesion of Streptococcus mutans
چکیده:   (1827 مشاهده)

Abstract

 

Background and Aim: Due to the increasing use of restorative materials, finding a 
suitable material with low adhesion rate and colonization of pathogenic 
Streptococcus mutans has a significant importance. The purpose of this study was the 
comparison of the adhesion rate of Streptococcus mutans to “Nano-hybrid composite” and “Amalgam” at 1, 3, and 7 day 
intervals.
Methods and Materials: In this experimental study, 72 samples of Amalgam and composite resin were placed in two equal groups and exposed to bacterial suspension holding 1× 106 cell/ml and after three time periods of 1, 3, and 7 days, the restorative material samples were suspended in 1cc of physiologic serum, and 100µl of the 
suspension was cultured on Blood Agar medium. After 48 hours the number of Streptococcus mutans colonies were counted. The data were analyzed by T-test.
Results: The mean and standard deviation of Streptococcus mutans colonies adhered to Nano-hybrid composite resin at 1, 3, and 7 day intervals were measured 12.7±2.3, 1.5±2.12 and zero colonies, respectively. Adherence of Streptococcus mutans to composite resin during these three days, showed a significant statistical difference (p<0.005). The mean and standard deviation of colonies, which adhered to Amalgam at 1, 3 and 7 day intervals were 32±7.01, 18.8±3.8 and zero colonies, correspondingly. The adherence of Streptococcus mutans to Amalgam during these three days showed a significant statistical difference (p<0.001). The comparison between Amalgam and composite resin showed that the adherence of Streptococcus mutans to composite resin was lower during the first and the third day and the results were statistically significant (p<0.001).
Conclusion: The result of this study showed that adhesion of Streptococcus mutans to Nano-hybrid composite is lower than  the adhension to Amalgam.
