Patients who begin endodontic therapy with nosymptoms may experience pain during therapy or after obturation of the canal system. Part 2 of this study analyzed the relationship between postobturation pain and clinical factors or conditions existing before, during, and after root canal therapy. Significant relationships were found between postobturation pain and interappointment pain and between postobturation pain and the type of chemical agents used for irrigation and intracanal medication. Of the 229 patients included in this study, 109 (47.6%) reported postobturation pain at some time during the 60-day postobturation observation period. The highest incidence and degree of postobturation pain occurred during the first 24 h. Sixty days after obturation, 227 (99.1%) patients were free of symptoms.
