ABSTRACT
The incidence of dental caries /Is/ on deciduous molars in 1216 children aged 3 to 8 from Plovdiv has been studied. The results showed highest Is in the fissures of m1 and m2 and lowest Is on the smooth surfaces. The incidence of dental caries is getting higher with statistically significant differences in the lower jaw up to the 6th year and in the upper jaw up to 7th year of age. Is in the lower jaw is higher than that of the upper jaw only in the fissures.

An assessment of the oral hygiene and periodontal health was made in 1596 school children (777 boys and 819 girls) aged 7-14 years from randomly selected classes and schools in Plovdiv, Bulgaria. The oral hygiene status of the school children assessed by the plaque indexes (PLI) of J. Greene and J. Vermillion, and that of J. Silness and H. Löe was found to be rather poor. The relative share of subjects with plaque index of 0.00 to 1.00 was found to increase with age for both sexes. The relative share of children with chronic catarrhal gingivitis was 42.61 +/- 2.34 indicating the necessity of active prophylaxis and treatment of the disease. A tendency was observed towards an increase of the disease incidence in comparison with data obtained in a 1983 study. A correlation between the hygiene status and chronic gingival inflammation in 14-year-old school children was found.

The following parameters were studied in 71 subjects, aged from 7 to 38 with chronic catarrhal gingivitis, invaded by T. tenax: oral-hygienic index of Green and Vermillion before the specific Fasigyn treatment and on 3, 7, 14 and 30 days after the treatment; the presence of complement-combining antibodies against T. tenax and the dynamics of antibody synthesis by 3, 6, 12 and 15 month after the treatment. Thirty one subjected with chronic catarrhal gingivitis, non invaded by T tenax were studied as controls. It has been established that in 53.52% of the subjects with chronic catarrhal gingivitis, invaded by T tenax, the inflammatory changes in gingiva disappeared as early as the third day after the specific Fasigyn treatment and in the rest--by 30 day. Higher values of complement-combining antibodies against T. tenax with a titre from 1:40 to 1:2569 were established in 65.34% from the subjects with chronic catarrhal gingivitis, invaded by T. tenax. The titre of antibodies sharpy decreased by month 3 and was normalized by months 6-12 after Fasigyn treatment.
