Sažetak
The aim of this study was to investigate the microbial flora of periapical ostitic lesions in single rooted teeth. Periapical processes in
which the root canal was open and those in which the canal was closed (reinforcement) were analysed. Samples for microbiological analysis were taken during the operation - apicotomy. On the whole the results obtained agree with current knowledge of the microbial flora in odontogenic infection. The polymicrobial composition of the flora with a significant share of anaerobic bacteria and reduced microbial flora in closed ostial lesions are the basic characteristics of periapical infection. The most frequent isolates found were from the streptococci group, and the most frequent anaerobe, Veillonela. It was determined that streptococci occur more frequently in closed ostial processes.
