Effects of root canal therapy on the intracanal microbiota

Microbiota infected necrotic masses tend to dominate the anaerobic bacteria, while facultatives, as a rule, only a small portion of the root canal flora. However, there is a wide variety and large number of individual types and combinations of species may be associated with the development and continuation of apical periodontitis. Therefore, and because the potential for organisms that prevail in biofilms structures on the root canal wall, there is little support for treatment approaches, which selectively focus on specific organisms.

The results of domination facultatives, especially therapy-enterococci resistant retreatment cases (in cases where the lesions have appeared or were unable to heal after endodontic treatment; 35, 60), suggest that in this case is defined as a rule, effective against anaerobes. Hence the reason that the RCT, if not effective, it can choose to have the most stable segment of the root canal microbiota (11). Survivors exposed to microorganisms to antimicrobial measures in RCTS may change their physiology to the changed ambient conditions, established treatment (9).

For example, changes in pH with the help of calcium hydroxide medication may cause the release of stress proteins solutions survival more resistant to further treatment attempts (10). Therefore, it can be seen how important it is to make the best possible efforts to eliminate the microorganisms must be taken at the initial treatment. It seems reasonable, therefore, to warn against the procedure, using the equipment and chemical disinfection is carried out only halfway, and postpone completion of the biomechanical tools for the subsequent session. ..
