Brief summary
The purpose of this randomized clinical trial was to evaluate the incidence of postoperative pain after retreatment using different techniques. Patients whom need retreatment were included. The presence of postoperative pain was assessed after retreatment cases at 1, 6, 12, 24 and 48 hrs.
Detailed description
The aim of this clinical study was to evaluate the intensity and duration of postoperative pain after single-visit and multiple-visit root canal retreatment procedures. Patients who have asymptomatic failed endodontically treated teeth were included in this study and routine channel treatment procedure will be applied to these teeth. All of the patients have been recruited from the Istanbul Medipol University Dental Clinics in Istanbul. Eighty asymptomatic teeth were randomly participated into four treatment groups in terms of intracanal medicament applied. The presence of postoperative pain was assessed after 1, 6, 12, 24 and 48 hrs. Postoperative pain was recorded by each patient by using visual analogue pain scale. Before the retreatments, the nature of the study, complications and associated risks were totally explained and written informed consent was obtained from all study participants. The patients were offered local anesthetic before the treatment start. The routine root canal retreatment procedure was applied. Different intracanal medicaments used between sessions in accordance to the manufacturers' instructions. At the end of retreatment, each patient was given an evaluation sheet, explained the treatment procedure and using of visual analogue pain scales, and informed to be returned during the following one week. After one week the teeth was examined according to for pain intensity, percussion & palpation sensitivity, swelling, analgesic intake and clinical status.
Interventions
OTHERSingle-Visit Retreatment
The teeth in this group were treated according to the guidelines for root canal retreatment in single-session. The filling was removed and cavity was opened. Then root canal filling was removed from the root canals completely using retreatment kit. After irrigation protocol, root canals were obturated with gutta percha and coronal restoration was made using composite and/or fully crown if necessary.
DRUGMultiple-Visit-Calcium Hydroxide
The teeth in this group were treated according to the guidelines for root canal retreatment in multiple-session. The filling was removed and cavity was opened. Then root canal filling was removed from the root canals completely using retreatment kit. After irrigation protocol, root canals were treated with calcium hydroxide and the cavity was filled with temporary restorative material.
DRUGMultiple-Visit-Corticosteroid Paste
The teeth in this group were treated according to the guidelines for root canal retreatment in multiple-session. The filling was removed and cavity was opened. Then root canal filling was removed from the root canals completely using retreatment kit. After irrigation protocol, root canals were treated with corticosteroid & antibiotic paste and the cavity was filled with temporary restorative material.
DRUGMultiple-Visit-Antibiotic Paste
The teeth in this group were treated according to the guidelines for root canal retreatment in multiple-session. The filling was removed and cavity was opened. Then root canal filling was removed from the root canals completely using retreatment kit. After irrigation protocol, root canals were treated with an antibiotic paste and the cavity was filled with temporary restorative material.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in Postoperative Pain after Retreatment at 48 hours. | Baseline, 1, 6, 12, 24 and 48 hours. | The primary outcome measure of the study was to assess if different intracanal medicaments and single-visit root retreatment influence the occurrence of postoperative pain.Postoperative pain was assessed using a well defined Heft-Parker visual analogue scale (VAS) scale. Each patient recorded the pain level on a 170-mm VAS scale experimental basis for revising the graphic rating scale for pain in well-defined categories at 5 time intervals as 1, 6, 12, 24 and 48 hours after treatment.The mm marks were removed from the scale and the scale was divided into 4 categories: No pain or faint pain corresponded to 0 mm. Mild pain was defined as greater than 0 mm and less than or equal to 54 mm. Mild pain included the descriptors of weak and mild pain. Moderate pain was defined as greater than 54 mm and less than 144 mm. Intense pain was defined as equal to or greater than 144 mm. Intense pain included the descriptors of strong, severe, and maximum possible. |
