title: Comparative Evaluation of the Antibacterial Efficacy of Type II Glass lonomer Cement, Type IX Glass lonomer Cement, and AMALGOMER™ Ceramic Reinforcement by Modified "Direct Contact Test": An in vitro Study.
abstract: BACKGROUND
  Streptococcus mutans (ATCC25175) has a profound effect on the incidence of dental decay in the human population. Many studies have been performed to assess the antimicrobial activity of different cements. However, little or no information is available about the antibacterial properties of Type II glass ionomer cement (GIC), Type IX GIC, and AMALGOMER™ ceramic reinforcement (CR).
  
  
  OBJECTIVE
  To comparatively evaluate the antibacterial activity of Type II GIC, Type IX GIC, and AMALGOMER™ CR by modified direct contact test.
  
  
  METHODS
  The total sample size was 72 which was divided into four study groups. Six wells were coated by each: Type II GIC, Type IX GIC, AMALGOMER™ CR, and control group (only S. mutans). Statistical analysis was done using analysis of variance and the intergroup comparison was done using post hoc Tukey test.
  
  
  RESULTS
  AMALGOMER™ CR was found to have a better antibacterial effect as compared with Type II and IX GIC.
  
  
  CONCLUSIONS
  AMALGOMER™ CR can serve as a valuable cement in pediatric dentistry due to its anticariogenic property. How to cite this article: Hugar SM, Assudani HG, Patil V, Kukreja P, Uppin C, Thakkar P.
