Diagnoses for Persistent Dentoalveolar Pain following Root Canal Therapy

Patients were followed for six months after they completed their root canal treatment. This nested case-control study brings those patients who were still reporting pain at 6 months, as well as their age-, gender- and tooth-matched controls, into the clinic to be evaluated by endodontic and orofacial pain experts. The primary goal of this study is to determine the proportion of patients with pain who would best be managed with typical dental care compared to those who have a non-odontogenic source for their pain, so that treatment directed at the etiology of their pain can occur.
