The key factor in the production of pulp and periapical inflammation is represented by the presence of bacteria in the root canal system and the outcoming toxins. Bacterial biofilm is identifiable in the various areas of the endodontic space, but due to the complexity of the internal anatomy of the root canal, bacteria removing is yet difficult to obtain, a particularly important step for treat...
