The isolation of Streptococci was performed from dental plaque in 59 dental hygienic students to investigate the intraoral distribution of caries-inducing Streptococcus mutans. Streptococci could be easily isolated from dental plaque at high rate in anaerobic system using Gas Pak on the Chapman's Mitis salivarius agar plates at 37℃ for 24 hr and the isolation appeared as in grey-white circular colonies varying in size from 0.5 to 1.0 mm. The isolation rate from pits and fissures, predilection areas of dental caries, were a little higher, however, this work did not completely explaine the relationship Streptococcus mutans to dental caries and the isolation procedure must be more examined. The isolated Streptococci were morphologically identical with reference strain of Streptococcus mutans on electron microscopic study.
