The purpose of this study was to compare the shear bond strength and the anticariogenicity of glass ionomer cement with conventional bonding resin and fluoride releasing rThe insoluble glucan is the major substance of dental plaque. In order to isolate the bacteria inhibiting the foi ¢¥nation of insoluble glucan in disposable cuvette, saliva was got from about 10 thousand children. The isolated bacteria were tested by API 20S kit and API 50 CHL kit. These bactreia were identified as Streptococcus oralis, Streptococcus mitis, Streptococcus mitior, Streptococcus sanguis, Enterococcus durans, Lactococcus laths, and Lactobacillus acidophilus. When Streptococcus mutans was cultured with Streptococcus oralis, Streptococcus mitis, Streptococcus mitior, Streptococcus sanguis, Enterococcus durans, Lactococcus lactic, or Lactobacillus acidophilus in disposable cuvette, the optical density at 550 nm was 0.823, 0.912, 0.894, 0.878, 0.753, 0.845, 1.021 respectively, while being 1.503 in the disposable cuvette cul-
turing Streptococcus mutans only.
