Endodontic Therapy (Root Canal Therapy)
Root canal therapy (endodontic therapy) consists in a pulpotony, which is the removal of a pathologically changed pulp (a gelatinous connective tissue, colloquially called ‘a nerve’) from a tooth’s chamber and root canals, as well as the chemo-mechanical preparation of the canals and filling them afterwards.
A correct root canal treatment demands X-raying the patient’s tooth. An X-ray photograph lets know the morphology of the root canals.
During endodontic therapy local anaesthesia is used, so the treatment is painless for the patient.
Root canals are prepared with the use of hand instruments, for example Kerr’s files , Headstom’s files or root canal files S-type, and machine instruments, such as ProTaper, GTX, etc. After preparation, root canals are filled with gutta percha and a sealer (AH plus paste).
We use two methods of filling:
– lateral condensation of cold gutta percha,
– vertical condensation of warm gutta percha.
During endodontic therapy we use modern dental equipment, namely: Raypex Endometer, X-smart Micro Motor, Super Endo (a system used for filling root canals with warm gutta percha) or Zeiss Microscope.
The number of the patient’s visits at the office is reduced to a minimum. The visits are necessary to minimise the risk of another infection of the already prepared root canals. However, if the tooth condition allows, a single-visit treatment is provided.
Still, in case of inflammatory condition of the periapical tissues (mainly suppuratation), as well as during the treatment of multilocular teeth, where complex morfology of dental cavities need to be dealt with, the number of visits can be higher (two or three).
When the treatment is finished, the tooth is always X-rayed (a follow-up radiogram). The X-ray is also necessary when, during the preparation of the root canals, there are some doubts about their working length. Even so, the decision about X-raying is always considered and purposeful.
In more difficult cases it is necessary to use a surgical microscope, because it provides a better sight of the canal’s interior. At our dental office, we use the microscope of Zeiss company, which has been the leader on the optical market for decades.
