Abstract

Carious lesions on the teeth surfaces of about 150 extracted human teeth were sampled from the visnagar city, Dist-Mehsana, Gujarat, India. Bacteria and Yeast were isolated on Mitis salivarius bacitracin agar, Rogosa SL agar and Candida Chrome agar. The biochemical characterization showed the dominance of S.mutans with other streptococci. It included S.mitis, S.oralis, S.salivaricus, S.hyointestinalis, S.gordonii, S.sanguinis, S.parasanguinis, S.gallolyticus ssp gallolyticus. The occurrence of key lactobacilli were reported viz. L.salivarius, L.viridescens, L.fermentum, L.helveticus, L.lactis, L.plantarum, L.bulgaricus, L.casei subsp.casei, and L. acidophilus. Beside C.albicans, other Candida species were also found.

The data obtained in this study showed that only limited types of microorganism could be isolated by customary microbiological techniques. Future investigation needs to devise more competent methods of isolation and characterization of uncultivable aerobes and anaerobes which would help us to know the complex pathogenesis of dental caries.
