The dental plaque harbours a diverse range of bacteria such as Streptococcus mutans , Streptococcus sanguis , Streptococcus sobrinus , Lactobacillus spp , Actinomyces spp . etc, embedded in a matrix of polymers of bacterial and salivary origin.,, Therapeutic procedures used in the treatment of caries do not always eliminate all the microorganisms in the residual tissues, leading to development of recurring caries and frequent cause of replacement of restorative materials. We compared the in vitro antibacterial activity of three glass-ionomer cements - Fuji II (GC Int. Corp.), Vitremer (3M Dental), Miracle Mix (GC Int. Corp.) and a polyacid modified composite resin (compomer) restorative cement - Dyract (Densply DeTrey) against Streptococcus mutans (ATCC 25175) and Streptococcus sanguis (ATCC 10556) using BHI agar plate diffusion assay., Chlorhexidine (0.2%) was used as the positive control and sterile isotonic saline was used as negative control.
All three glass-ionomers exhibited antibacterial activity. Vitremer showed the maximum activity, followed by Fuji II and Miracle Mix. The primer component of the compomer showed activity whereas Dyract failed to show any activity [Table - 1].
This study demonstrates antibacterial activity of restorative cements against prototype cariogens. The antibacterial activity of these materials may not be limited to streptococci but also against other cariogenic bacteria and other orodental pathogens., Though the exact nature of action and degree of effectiveness have not been elucidated, in light of the present and other reported results, the use of glass-ionomer cements could be indicated in the restorative treatment of dental caries.
