This treatment is commonly carried out and can sometimes be long and tedious, as for example on molars with several roots.~According to numerous studies, patients consider endodontic treatments as one of the most stress-inducing dental procedures. Another study also reports satisfaction during root canal treatment in public health service.

This type of research can enable us to keep a broad approach of patients' experience and to stay faithful to it.
