ABSTRACT
Objective:
To compare the quantities of water-soluble, water-insoluble glucans synthesized by S. mutans in 3-4 years old children with high dmft and no caries.Methods:
The quantities of water-soluble and water-insoluble glucans synthesized by S. mutans from dental plaques of children with high dmft (dmft≥5) and caries-free (dmft=0) were measured using the anthrone method.Results:
S. mutans isolated from the children with high dmft had stronger ability in producing both water-soluble and water-insoluble glucans than those isolated from the caries-free children (0.0332 mg/ml v.s. 0.0192 mg/ml and 0.0357 mg/ml v.s. 0.0215 mg/ml respectively). Children with high dmft harbored more isolates with higher water-soluble or water-insoluble glucans producing ability than caries-free children. Water-insoluble glucans produced by all the clinical isolates is higher than water-soluble glucans (0.0301 mg/ml v.s. 0.0267 mg/ml) and the difference was statistically significant.Conclusion:
There may be a correlation between the extracellular glucans producing ability of S. mutans and the caries susceptibility in deciduous teeth.
