Abstract:
OBJECTIVETo investigate the initial colonization of Mutans streptococci (MS) on teeth of children.
METHODSDental plaque was collected from 123 children aged from 7 to 42 months. MS was isolated by culturing on selective medium and identified by biochemical tests.
RESULTSMS was detected in 51 of 123 children. The rate of colonization was 41.5%, and the mean age of colonization was 29 month. The incidence of MS infection increased with age and tooth eruption, and reached peak at 25 - 31 months, which was statistically significant. There was a correlation between infection of MS and dental caries.
CONCLUSIONThe results indicate that the susceptive period of MS infection is from 25 to 31 months when the second primary molars erupt. MS infection is associated with dental caries.
