Abstract:

To determine the relationship between bacterial colonization of tooth surfaces and dental caries, selective agar media-MM10 Sucrose, Rogosa SL and Blood agar were used to isolate bacteria from the scrappings of 60 tooth surfaces of 30 children and young adults. Mean age +/- SD was 13.3 +/- 4.1 (range seven to 19 years). Streptococcus mutans was isolated from 36 surfaces representing 60pc Lactobacillus species from 38 surfaces (68pc), and Actinomyces species from 12 surfaces (20pc). The individual prevalences of these organisms decreased with age. The distribution of bacteria according to surfaces examined showed that the pits and fissures were the main habitat of Streptococcus mutans and Lactobacilli were sensitive to erythromycin. Actinomyces species were 100pc sensitive to Penicillin. All the bacteria species isolated were also found to be 100pc sensitive to Olfoxacin (Tarivid). It is suggested that the use of antibiotics may stop the growth of cariogenic bacteria in individuals and thereby contribute to a decline in the incidence and prevalence of dental caries in the community.
