In the last ten to twenty years, there have been great innovations in the art and science of root canal therapy. Dentists now must be educated on current concepts in order to optimally perform a root canal.

Root canal therapy has become more automated and can be performed more precisely thanks to machine-driven rotary technology and more advanced root canal filling methods. Most root canal procedures are done in one dental visit which may last around 1 to 2 hours. The aid of cone-beam CT scanning can allow a more precise diagnosis, which improves the effectiveness of the treatment.

Endodontists perform root canal therapy using loupes, or other forms of magnification like surgical microscopes.

Techniques and instruments can vary, but the ATTITUDE towards proper isolation of the tooth with a rubber dam and proper disinfection of the full length of the root canal and achieving a proper seal after the procedure remain the MAIN FACTOR for a long term success.
