Postoperative Pain of Rotary Versus Reciprocating Motions of Two Single Files

September 16, 2021 updated by: Ahmad Elheeny, Minia University

Postoperative Pain After Pulpectomy of Primary Molars Using With Rotary Versus Reciprocation Motions of Two Single Files: A Randomized Clinical Trial

An equivalent parallel randomized clinical trial was approved by the local University Committee of Ethics. 260 children with necrotic primary molars were allocated into 2 equal groups (82 children per group). The participants were allocated into two groups; group "1" teeth were instrumented with OneShape rotary system (Micro Mega, Besancon, France), and group "2" teeth were instrumented with WaveOne Gold reciprocating system (Dentsply Maillefer, Ballaigues, Switzerland). Postoperative pain was assessed using a four-point pain intensity rating scale adopted from Wong-Baker FACES (WBF) pain scale . The face scale consists of four faces with a brief title describing each face representing a scale from the first face (score 1), second face (score 2), third face (score 3), and forth face (score 4) 3. Postoperative pain was assessed at 6 six time intervals (at 6, 12, 24, 48, 72 hours and one-week).

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.

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.

Ages Eligible for Study

4 years to 8 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Children ages from 4 to 8 years classified as class I or II according to the American Society of Anesthesiologists (ASA).
  2. No previous dental experience.
  3. Non-vital primary molar (necrotic or with chronic apical periodontitis) which confirmed radiographicly with the presence or absence of periapical radiolucency.
  4. Severe tooth mobility.

Exclusion Criteria:

  1. Severe behaviour or emotional disabilities.
  2. Analgesic intake in the preceding 12 hours.
  3. Non-restorable crowns of primary molars.
  4. Radiographic presence of internal root resorption or massive bone destruction.

Active Comparator: Rotary motion using OneShape single file
File size 25 with a taper of 0.06 was mounted to a 6:1 speed-reduction headpiece powered by X Smart Plus endomotor (Dentsply Maillefer, Ballaigues, Switzerland). The speed and torque were set to 400 rpm and 1 N.cm torque, respectively. In a picking motion without pressure, mechanical preparation began with the first RC two-thirds followed by the next 3 mm followed by the full WL.
Device: OneSahpe single file

Active Comparator: Reciprocating motion using WaveOne Gold single file
A Primary file size 25 a taper of 0.07 was installed to pre-programmed reciprocation angles and speed for the WaveOne system handpiece of an endomotor (X Smart Plus endomotor (Dentsply Maillefer, Ballaigues, Switzerland). After ensuring a passive fit of the hand file along the predetermined WL, the RC coronal two-thirds was initially instrumented then followed by the full WL.

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
Time Frame: One week
Postoperative pain was assessed using a four-point pain intensity rating scale adopted from Wong-Baker FACES (WBF) pain scale . The face scale consists of four faces with a brief title describing each face representing a scale from the first face (score 1), second face (score 2), third face (score 3), and fourth face (score 4) 17. Postoperative pain was assessed at 6 six time intervals

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
