Root canal treatment, also called endodontic therapy, is necessary when the pulp of the tooth is infected following significant caries, cracks in the enamel or a trauma (shock). If the inflamed or infected pulp is left untreated, it can cause pain or lead to an abscess. This treatment involves the removal of the infected pulp, the disinfection, and the filling and sealing of the root canal system. The tooth is then restored with a permanent filling or a crown.
To clean the inside of the tooth, we use the combination of a mechanical method (instruments that remove the debris inside the pulp chamber and root canals) and a chemical method (desinfecting solution injected into the tooth to kill bacteria).
To remove the pulp from the root canals (mechanical method), the dentist uses precision instruments (endodontic files). These can be traditional manual files or electrically-powered instruments (rotary endodontic instruments).
Advantages of rotary endodontics
Rotary endodontic methods offer several advantages over manual root canal treatments:
- Faster treatment (often in one appointment);
- Patients feel much more comfortable during the treatment;
- More reliable;
- No unpleasant noises;
- More precision (the flexibility of instruments allows a better negotiation of curved canals);
- Higher quality treatments (more consistent).
