With a purpose of elucidation the causative relationship between specific oral bacterial
species and rampant dental caries, the distributions of S. mlitans and Lactobacillus in
dental plaque from 21 children with rampant dental caries in the primary dentition were
examined.
The following results were obtained .
1. S. mutans was detected in the plaque of all children and the distribution to total
cultivable oral microorganism wes 3.75%, and it was significantly higher (P<0.05) in
plaque taken from carious surface than from sound surface.
2. Lactobacillus was detected in the plaque of all children and the distribution to total
cultivable oral microorgaism was 1.75% and it was significantly higher(P<0.05) in plaque
taken from carous surgace than from sound surface.
