title: Antibacterial effects of hybrid tooth colored restorative materials against Streptococcus mutans: An in vitro analysis.
abstract: OBJECTIVE
  The objective of this study was to evaluate the antibacterial effect of two hybrid restoratives, namely resin modified glass ionomer cement (GC Fuji II™ LC, GC Corporation, Tokyo, Japan) and giomer (Beautifil-II, Shofu Inc., Kyoto, Japan) against Streptococcus mutans [Microbial Type Culture Collection (MTCC), 890].
  
  
  METHODS
  The antibacterial effect was evaluated using an agar diffusion test. The prepared wells in petri dishes were completely filled with chlorhexidine (positive control group), resin modified glass ionomer cement and giomer respectively. Prepared bacterial suspension was poured over the petri dish and was spread evenly using the plate spreader. The culture plates were placed in the incubator for 24 h at 37°C. The antibacterial activity was evaluated after 24 h, 48 h, and 7 days for each group in triplicates.
  
  
  CONCLUSIONS
  The results of the antibacterial effect of the tested materials were collected, statistically analyzed using the ANOVA test to determine the difference between the mean diameters of the inhibition zone produced. The mean zone of bacterial inhibition was found to be more with the giomer specimens at all time periods. However, this inhibitory activity showed a gradual decrease over a period of 7 days and the maximum inhibition was evident after 24 h with both the test materials.
