Abstract

Objectives: The aim of the present study was to measure the level of Streptococcus mutans(S. mutans), the major causative agent in dental caries, and to examine the relationship between S. mutans level and dental caries experience.
Methods: The present study was carried out in 41 university students. S.mutans plaque was detected in the saliva using Dentocult®-SM and was measured in absorbance. The data were analyzed in the relevance for number of dental caries experience.
Results: The group of S. mutans value has progressive caries, which was higher than that of non-suffering caries(p<0.05). More caries experience showed higher value of S. mutans(p>0.05). According to the relationship with DMFT, level of S. mutans and absorbance, correlation with the level of salivary S. mutans is shown statistically highly significant (p<0.01). The level of S. mutans in saliva and plaque and absorbance is statistically significant(p<0.05).
Conclusions: The levels of S. mutans in both group of high caries experience and progressive caries was highly detected, continuous oral health management should be carried out to prevent the possible dental caries.
