In Vitro Comparison of the Effect of Nano-Hybrid Composite Resin and Amalgam on the Adhesion of Streptococcus Mutans
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. Method...
متن کاملInfluence of amalgam, alloy, and Hg on the in vitro growth of Streptococcus mutans: III. Effect of specimen age and composition.
We will now summarize the conclusions from parts I, II and III of this study. A test procedure has been developed that provides a simple, quick, and nondestructive means of monitoring the in vitro growth of S mutans in the presence of amalgams and alloys. The spectrophotometric readings are related in a simple way to growth expressed as dry weight of bacteria and metabolic products. Results are...
متن کاملAdhesion of Streptococcus Mutans to Zirconia, Enamel, IPS Empress II, Noble Alloy and Base-metal: An In-Vitro Comparative Study
Introduction: With increased usage of restorative materials, dentists are more concerned in choosing a suitable material with lower adhesion of pathogens like streptococci. This comparative in vitro study aimed to compare adhesion of streptococcus mutans to zirconia, IPS Empress II, noble alloy, and base-metal. Materials and Methods: In this descriptive study, 50 specimens (5 mm diameter disk ...
متن کاملEvaluating the effect of 0.05% fluoride and chlorhexidine 0.2% mouthwashes in comparison to nanosil D1+F mouthwash on Streptococcus mutans, in vitro
Abstract Background & Aim: Oral diseases, especially dental caries, are still prevalent in the most developing countries which cost a lot for patients and the health care system. One of the most important ways to reduce costs is to prevent caries. Therefore, the aim of this study was to evaluate the effect of chlorhexidine and fluoride mouthwashes in comparison with Nanosil D1+F combined mouthw...
متن کاملResistance to mercury and antimicrobial agents in Streptococcus mutans isolates from human subjects in relation to exposure to dental amalgam fillings.
Resistance to cefuroxime, penicillin, tetracycline, and mercury is reported for 839 Streptococcus mutans isolates from 209 human study subjects. The MICs of these drugs did not differ for isolates from one dental amalgam group and two nonamalgam subsets: a group with no known exposure to amalgam and a group whose members had their amalgam fillings removed.
