Postoperative Pain in Single-visit and Multiple-visit Retreatment Cases
Condition: Postoperative Pain; Root Canal Infection; Endodontic Disease
MeSH terms: Dental Pulp Diseases; Pain, Postoperative
Study type: Interventional
Phase: Phase 4

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.
    

Intervention name(s): Single-Visit Retreatment; Multiple-Visit-"Calcium Hydroxide"; Multiple-Visit-"Corticosteroid Paste"; Multiple-Visit-"Antibiotic Paste"
Intervention type(s): Other; Drug; Drug; Drug
Intervention description(s): 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.; 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.; 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.; 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.
