The article discusses a study on the presence of hemolytic streptococci bacteria in mouths. Streptococci bacteria have been shown to promote the progress of various dental diseases including caries. In order to determine the occurrence of these bacteria, samples were taken from over 100 volunteers. Results showed that the bacteria were not present in very many mouths, and are probably not a direct cause of periodontal diseases.

    Dental caries has been an intractable disease in spite of intense dental research. The metabolic acids produced by mutans streptococci demineralize the tooth surface and lead to dental caries. The enzyme glucosyltransferase (GTF) produced by mutans streptococci is the key factor in this process....
