February 27, 2018 updated by: Keziban Olcay, Istanbul Medipol University Hospital

The Clinical Comparative Evaluation Of Postoperative Pain In Single-Visit And Multiple-Visit Pretreatment Cases: A Prospective Randomized Clinical Trial

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

ACTIVE_COMPARATOR: Single-Visit Retreatment
Root canal retreatment were performed according to the guidelines for single-visit endodontic treatments.
Other: Single-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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Postoperative Pain after Retreatment at 48 hours.
Time Frame: 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.
Baseline, 1, 6, 12, 24 and 48 hours.
