Detailed Description

The aim of this prospective, randomized, clinical trial was to evaluate the effect of 1.3% sodium hypochlorite (NaOCl) concentration versus 5.25% NaOCl concentration on post-operative pain and medication intake in adult patients with pulp necrosis in mandibular molars. Medical and dental history was obtained from all participants in this trial and clinical and radiographic evaluation for teeth was recorded. Participants with pulp necrosis with or without apical periodontitis were included. After access cavity preparation, participants were randomly assigned to one of the following groups: experimental group (irrigation using 1.3% NaOCl) or control group (irrigation using 5.25% NaOCl ). Two-visit root canal treatment was performed with a week interval in between visits. Each patient received a 7-day diary to record postoperative pain and rescue medication intake. Post-operative pain was measured at the following time points: immediately , 3, 24, 48 hours and 7 days after the first visit and postobturation.

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.

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
Postoperative pain using a pain-measuring scale
Time Frame: immediately after treatment
Postoperative pain is measured using the Numerical Rating Scale (NRS) which is an 11-point scale from 0-10 where 0 represents no pain and 10 represents the worst pain measured immediately after the first visit
immediately after treatment
Postoperative pain using a pain-measuring scale
Time Frame: 3 hours
Postoperative pain is measured using the Numerical Rating Scale (NRS) which is an 11-point scale from 0-10 where 0 represents no pain and 10 represents the worst pain measured 3 hours after the first visit
3 hours
Postoperative pain using a pain-measuring scale
Time Frame: 24 hours
Postoperative pain is measured using the Numerical Rating Scale (NRS) which is an 11-point scale from 0-10 where 0 represents no pain and 10 represents the worst pain measured 24 hours after the first visit
24 hours

Time Frame: 48 hours
Postoperative pain is measured using the Numerical Rating Scale (NRS) which is an 11-point scale from 0-10 where 0 represents no pain and 10 represents the worst pain measured 48 hours after the first visit
48 hours
Postoperative pain using a pain-measuring scale
Time Frame: 7 days
Postoperative pain is measured using the Numerical Rating Scale (NRS) which is an 11-point scale from 0-10 where 0 represents no pain and 10 represents the worst pain measured 7 days after the first visit
7 days
Postoperative pain using a pain-measuring scale
Time Frame: immediately after obturation
Postoperative pain is measured using the Numerical Rating Scale (NRS) which is an 11-point scale from 0-10 where 0 represents no pain and 10 represents the worst pain measured immediately after obturation.

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
Sham medication intake incidence
Time Frame: 7 days
Sham medication intake incidence (Yes/No) taken as an initial rescue medication in case of postoperative pain.
7 days
Analgesic medication intake incidence
Time Frame: 7 days
Analgesic medication intake incidence (Yes/No) as a rescue medication in case postoperative pain persisted after the sham medication intake.
