ABSTRACT
Considerable evidence indicates that the disaccharide, sucrose is probably the major dietary factor in dental caries formation and much subsequent research has gone into the search for another sweetener to replace sucrose. Currently, there is much interest in the development of new sweeteners and the cariogenic properties of sugar alcohols. The present study aimed to examine the cariogenic properties of sugar alcohols (xylitol, sorbitol, mannitol) and sucrose on growth pattern and acid production of S. mutans, S. mitis, S. salivarius, S. sanguis, S. faecalis, S. viridans, L. casei and L. acidophilus in vitro by using Photo Electrical Colorimeter and pH meter. In conclusion the results in this study showed that out of sugar alcohols, xylitol is the only compound which, depending on its concentration, significantly did not affect the growth and acid production of all tested micro organisms.
