November 16, 2022 updated by: Nermeen AwadAllah Abbas Ibrahim, Cairo University

Effect of Apical Third Enlargement to Different Preparation Sizes and Tapers of EdgeFile X7 on Postoperative Pain and Intra-canal Bacterial Reduction in Patients With Necrotic Pulp: A Randomized Clinical Trial

The aim of this prospective randomized clinical trial is to evaluate the effect of different apical size and taper preparation (35. 04; 35. 06; 45. 04 and 45. 06) on postoperative pain at 6, 12, 24, 48 and 72 hours, and intra-canal bacterial count in patients having mandibular premolars with necrotic pulps.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  • Patients will be clinically and radiographically examined and their eligibility will be assessed. Eligible patients will be treated in one visit.
  • Patients will be randomly assigned to one of 4 groups: experimental groups of root canal instrumentation with EdgeFile X7 to size #35/0.06 or #45/0.04 or #45/0.06 or the comparator group to size #35/0.04. Intra-canal bacterial count will be measured using a culture technique. Bacterial samples will be taken before and after root canal instrumentation. After endodontic treatment, patients will be given postoperative instructions and informed, in case of pain, to receive ibuprofen 400 mg as rescue medication.
  • Postendodontic pain intensity and incidence at the different pain categories (No, mild, moderate, severe) will be assessed at 6, 12, 24, 48 and 72 hours postoperatively using Numerical Rating Scale (NRS).

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.

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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.

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
Post-operative pain
Time Frame: up to 72 hours after endodontic treatment
Postendodontic pain will be measured using Numerical Rating Scale. The Numerical Rating Scale consists of a 0-10 scale, with (0) meaning "no pain" and (10) meaning "the worst pain imaginable". No or mild pain response will be considered success.
up to 72 hours after endodontic treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Intra-canal bacterial reduction
Time Frame: Bacterial samples will be taken Immediately after root canal instrumentation.
Intra-canal bacterial count will be measured using a culture technique. The resultant growth will be visually quantified by counting the number of colony forming units per millilitre (CFUs/ mL)
Bacterial samples will be taken Immediately after root canal instrumentation.
