Effect of Apical Negative Pressure Irrigation System at Cleaning Lateral Canals and Reduction of Periapical Lesions After Endodontic Therapy

December 19, 2017 updated by: KaVo Kerr
The aim of the present study is to assess with PA x-rays and CBCT scans the volumetric changes in periapical radiolucencies in endodontically treated teeth 1 year after endodontic treatment and evaluate how well the lateral canals are filled after irrigation with the new generation of negative irrigation pressure unit with and without the ultrasonic irrigation.

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

This is a single center, prospective clinical study conducted in patients who present for routine endodontic therapy. The study has been reviewed and approved by the Institutional Review Board (Ethics Committee) Aspire IRB located at Santee, CA. The clinical investigator will treat patients who present with radiographic evidence of periapical pathology and will randomize the subjects to either negative pressure irrigation system treatment (EndoVac Pure) with ultrasonic irrigation or negative pressure irrigation system treatment (Endovac Pure) without ultrasonic irrigation. All other aspects of the treatment (access, instrumentation and obturation will be according to clinicians conventional clinical judgment. Subjects will have a pre-treatment PA x-ray and CBCT scan before treatment, a PA x-ray at six months and a CBCT scan at one year post-treatment.

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.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Irrigation Technique 1
Patients randomized into this group will be treated using EndoVac Pure followed by Ultrasonic Irrigation.
Device: Irrigation Technique 1
Irrigation of root canals for this group will be performed using EndoVac Pure, an Apical Negative Pressure Endodontic Irrigation System intended for the delivery and evacuation of endodontic irrigation solutions during root canal procedures. The Endovac Pure is a negative pressure system that utilizes negative pressure irrigation so irrigants are suctioned apically from the pulp chamber to the apical terminus and then through the dental office High Volume Evacuation (HVE) valve (Hi-VAC) system. Endovac Pure is designed to be used with Sodium Hypochlorite (NaOCl or bleach) and EDTA (Ethylenediaminetetraacetic acid). This will be followed by Ultrasonic activation of the sodium hypochlorite solution using Minendo II ultrasonic unit.
Experimental: Irrigation Technique 2
Patients randomized into this group will be treated using EndoVac Pure only.
Device: Irrigation Technique 2
Irrigation of root canals for this group will be performed using the EndoVac pure system without Ultrasonic irrigation. The Endovac Pure is a negative pressure system that utilizes negative pressure irrigation so irrigants are suctioned apically from the pulp chamber to the apical terminus and then through the dental office High Volume Evacuation (HVE) valve (Hi-VAC) system. Endovac Pure is designed to be used with Sodium Hypochlorite (NaOCl or bleach) and EDTA (Ethylenediaminetetraacetic acid).

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 - Size of the lesion in the lateral canals at 1 year
Time Frame: 1 year after endodontic therapy

Evaluate the efficacy of EndoVac Pure at cleaning lateral canals as evidenced by post-treatment CBCT scans.

CBCT images will be analyzed and the size of the lesion will be measured and will be evaluated.
1 year after endodontic therapy
Change from baseline - Length of lateral canal filled at 6 months and 1 year
Time Frame: 6 months and 1 year post treatment
The study will also evaluate how well the lateral canals are filled after irrigation with the new generation of negative irrigation pressure unit with and without the ultrasonic irrigation The amount of filling material visualized in each lateral canal will be calculated and expressed as a percentage of linear extension (length of the lateral canal that was filled, in relation to its entire length in mm).
6 months and 1 year post treatment
Change from baseline - Area of the lateral canal filled at 6 months and 1 year
Time Frame: 6 months and 1 year post treatment
The study will also measure the area occupied by the filling material inside the lateral canal in relation to its entire area in mm²).
6 months and 1 year post 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
Change from baseline - Periapical radiographic healing
Time Frame: 6 months and 1 year after endodontic therapy

Compare the outcome of periapical radiographic healing 6 months and 1 year after endodontic treatment

The Periapical Radiographs will be analyzed and the size of the lesion will be measured in two dimensions: mesio-distal and coronal-apical. The lesion will be evaluated based on the findings below:

Evaluation of Radiographic Findings:

  1. Normal periapical structures
  2. Small changes in bone structures (PAI ≤2)
  3. Changes in bone structures (PAI ≥3)
  4. Periodontitis with well- defined radiolucent area
  5. Severe periodontitis
6 months and 1 year after endodontic therapy
