Rapid quantification of bacteria in infected root canals using fluorescence reagents and a membrane filter: a pilot study on its clinical application to the evaluation of the outcomes of endodontic treatment.

Objective. The bacterial examination has been performed during the course of the root canal treatment. In the present pilot study, the new developed method, using fluorescence reagents and a membrane filter, was applied to the detection and quantification of bacteria in infected root canals, in order to evaluate the outcomes of the treatment.

Cultivable anaerobic microbiota of infected root canals.

Objective. Periapical periodontitis is an infectious and inflammatory disease of the periapical tissues caused by oral bacteria invading the root canal. In the present study, profiling of the microbiota in infected root canals was performed using anaerobic culture and molecular biological techniques for bacterial identification.
