It is generally believed that the lactobacillus count in a measure of susceptibility for tooth decay of the public as well as the acidogenic potency in a mouth. However, numerous facilities and materiales which can be available in only civilized countries should be equipped on its practice.Sputocrit estimation of Lactobacillus count was originally found by Kondo and Onisi in their findings that bulk of oral desquamates obtainable in a gargled water is parallel with populations of organisms belonging to the glycolytic layer in the mouth, such as Streptococci, Veillonella, Lactobacilli, and Micrococci. Their findings, however, based on the results that were obtained from bulk of desquamate which was sedimented under 10000 rpm centrifugation. In the present work, a 800 rpm very popularhand centrifuge was used.The obtained bulks of desquamates in such way, significantly correlated to the intraoral. populations of Str. salivarius, Str. mitis, and Veillonella, but not to Lactobacilli and Fusobacteria at 1% level of significance.Thus, use of hand centrifuge seems to be simple substitude of sputocrit estimation of latent glycolytic potency in the mouth of the school children.For the sake of caries susceptibility, number of DF cavities and carious teeth were also counted, but results insignificantly correlated to the bulk of desquamates. Another possibility of neutral correlation between actual cavities and desquamation was discussed to be an inexisting relation.
