Prevalence, predictive factors and clinical course of persistent pain associated with teeth displaying periapical healing following nonsurgical root canal treatment: a prospective study

ConclusionsPersistent pain or discomfort associated with teeth showing periapical healing at the first review after NSRCT, decreased in intensity in most cases over the following 6  months. Longer‐term follow‐up revealed spontaneous improvement or symptom resolution in the majority of those with confirmed radiographic the absence of periapical disease. Five predictive factors (history of chronic pain, teeth with responsive pulps, association with pain, diagnosis of tooth crack before treatment and diameter of preoperative radiolucency) were identified.
