Antimikrobni učinak intrakanalne primjene ozona

Aim: The aim of this study was to determine the amount of aerobic, anaerobic, and total number of bacterial colonies after chemomechanical root canal treatment and after additional intracanal disinfection using ozone. Materials and Methods: Twenty - three patients with the same number of single rooted teeth (n=23) with periapical lesion (<5 mm) observed on retroalveolar radiogram or panoramic radiograph took part in this study. For the microbiological analysis three swabs were taken: immediately before (B1), after mechanical instrumentation and irrigation with 2.5% sodium hypochlorite (B2) and after chemomechanical treatment and additional intracanal ozone application (B3). Swabs were taken with sterile paper points, bacteria were cultivated and the results were interpreted after 14 days using the API 20A system. The data were analyzed by Wilcoxon Signed Rank Test measuring the number of bacterial colonies before and after the root canal treatment. Results: The difference between groups B1 and B2, B1 and B3 and B2 and B3 for all three groups: aerobic bacteria, anaerobic bacteria and total number of bacteria was statistically significant (p<0.05). Conclusion: Both methods showed a strong effect in bacterial number reduction. After the chemomechanical and additional ozone root canal treatment, the number of aerobic and anaerobic bacterial colonies further decreased compared to the measurements immediately before and after the chemomechanical root canal treatment. Because of the improvements in bacterial reduction after additional application of ozone in the root canal, this procedure is recommended for use in clinical practice.
