This study was carried out to evaluate and compare the anti-bacterial effects of glass ionomers (both conventional and resin – modified) and amalgam, on carious dentin. Sixty permanent molar teeth in twenty patients were selected for the study. Color and consistency of the carious dentin, and the bacterial counts at baseline and after six months were evaluated. Significant anti-bacterial activity [reduction in CFU per ml. after six months for total viable count (TVC), mutans streptococcus (MS) and lactobacillus (LB) counts] was shown by all materials and the results were statistically significant. The mean CFU per ml. of carious dentin after six months for conventional glass ionomer (Fuji II) was significant for TVC, MS and LB counts (p<001, <001, <002 respectively). The resin-modified glass ionomer (Fuji II LC) had similar effect on TVC and MS counts (p<001) but not with LB counts (p>.05). Amalgam too produced decrease in CFU, for all counts but the result was not statistically significant. After six months, harder and darker dentin was found beneath all the three materials, Resin – modified glass ionomers had a significant effect on both colour and consistency in more number of teeth as compared to the other materials
