[Relationship between dental status and salivary microbiology in adolescents]

The authors studied caries prevalence in connection with salivary caries related findings, in 349, 14-16 years old Hungarian adolescents, living in two different cities. DMF.T, DMF-S means, stimulated salivary flow, buffer capacity, Streptococcus mutans, Lactobacillus and Candida albicans counts in saliva were determined. The ratio of cariesfrre adolescents was 4.6% in the total population sample, DMF-T mean values were 7.24 +/- 4.86, DMF-S means 10.50 +/- 8.35. Mean secretion rate of stimulated saliva was 0.84 +/- 0.50, a low buffer capacity was found in 6.3% of the examined children. Ratio of carriers of Streptococcus mutans, Lactobacilli and yeasts in saliva was 89.7%, 73.9% and 47.7% respectively. DMF-T and DMF-S values, as well as S. mutans counts were lower in the capital than in the other city. Statistically significant correlations were found between DMF-S, DMF mean values and salivary microbiological counts.
