Objective: The aim of this controlled clinical trial was to assess whether radiotherapy interferes with pain levels in patients who have undergone endodontic treatment.

Materials and Methods: Sixty adult patients over the age of 18 years participated in this study, among these, 30 received radiotherapy to treat cancer in the region of the endodontically treated tooth. The patients were distributed two groups. Group SH2.5 (2.5% sodium hypoclorite) (n=30) e SH2.5PR (2.5% sodium hypoclorite after radiotherapy) (n=30). Only one tooth per participant was included in this trial. In order to shape the canals, it was used a Wave One Gold instrument, and canals were filled with AH Plus sealer. The canal preparation was accomplished with continuous canal irrigation using 2.5% sodium hypochlorite and a final rinse with EDTA 17% followed by sodium hypochlorite. The cavity was sealed using glass ionomer cement. Pain intensity was assessed using the visual analog scale (VAS).

Results: In the SH2.5 group, according to the visual analog scale, pain was mild at 6, 12, 24, 48, 72 hours and 7 days after endodontic treatment. In the SH2.5AR group, the pain was mild at 6 and 12 hours, and disappeared after that period, obtaining the shortest duration of pain (p<0.05).

Conclusion: Patients undergoing radiotherapy for the treatment of orofacial cancer had mild pain that disappeared 12 hours after treatment. Therefore, a null hypothesis was rejected.
