This study determined the frequency and/or intensity of postoperative pain and factors associated with such occurrence in endodontic treatments and retreatments performed by manual and reciprocating techniques, by undergraduate dental students at the Federal University of Pelotas. For that purpose, data were collected from the records of patients treated by last-term undergraduate students, in the period between January 2017 and July 2019, adding up to 182 treatments. Pain was recorded by the Numerical Pain Rating Scale (NPRS). The following predictive variables were considered in the outcome of postoperative pain: tooth, number of canals, symptoms, dental crown, indicated treatment and radiographic periapical index. The variables related to the treatments included the instrumentation techniques, number of sessions and apical limit of instrumentation. There was report of pain during treatment in 28% of records, while 11.5% did not report previous pain. In 149 cases (81.9%) included in this study there were no reports of postoperative pain, while mild pain was reported in 17 cases (9.3%), moderate in 6 (3.3%) and intensive in 10 (5.5%). In 67.4% of cases, the teeth were treated up to mark “0” of the apex locator, while in 32.6% the length was established at 1mm from this mark. There was no association between the type of treatment performed and the occurrence of postoperative pain (p=0.206). It was concluded that, among the evaluated factors, only the previous symptomatology was associated with higher frequency of postoperative pain.
