Title: Endodontic treatment accidents

The occurrence of endodontic irrigation accidents can be greatly reduced with training, technique and technology.

Root canal irrigation holds the main role in endodontic treatments. The most used endodontic irrigation solutions are: Sodium hypochlorite 1-5.2%; EDTA solution 10%-17%; Chlorhexidine 2%; MTAD (citric acid 4.25%, doxycycline 3%, surfactant-Tweed 80); Hydrogen peroxide.

Irrigation techniques can be manual or mechanical. Regardless of the irrigation system used, the solution must be introduced into the canal without pressure and the needle must not be blocked in the canal. The time required to clean a root canal is 30 minutes.

Exceeding the irrigant beyond the apex can cause important inflammatory reactions and pathological and neurological tissue consequences. Accidents that can occur during endodontic irrigation are: skin burns, skin and neurological damage, ecchymosis, edema.

Correct endodontic treatment cannot be achieved without dam isolation.
