Diagnoses for Persistent Dentoalveolar Pain Following Root Canal Therapy

This is a nested case-control study in which DPBRN Study 17 patients who still have pain at 6 months are seen 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 traditional 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.
