As the result of the latest changes in technology, root canal treatment can be successfully performed in one day, with no inconvenience to the client Using 3D imaging - Cone Beam Computed Tomography - we can quickly and precisely locate the inflamed zones of the teeth and jawbone. 3D tomographic imaging permits us to see not only the results of teeth infections but also the difficulties that can appear, such as failed attempts at endodontic treatment (broken instruments, untreated root canals, prepared margins, perforations). With us it is standard procedure to use operating microscopes equipped with video tracks, which empower us to improve our methods of clearing, preparing and filling root canals. Using these microscopes, we can notice anatomical irregularities, artificial obstructions in root canals (broken endodontic instruments), and complications of anterior treatments (perforations, resorptions). Being capable of using close-up tools and the most recent computer-guided oscillating systems to prepare root canals, as well as thermal condensation equipment to fill canals, we can now keep alive the teeth that would have been removed in the past.
