Brief summary

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.

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.

Interventions

DEVICEIrrigation 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.

DEVICEIrrigation 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).

Design outcomes

Primary

MeasureTime frameDescription
Change from baseline - Size of the lesion in the lateral canals at 1 year1 year after endodontic therapyEvaluate 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.
Change from baseline - Length of lateral canal filled at 6 months and 1 year6 months and 1 year post treatmentThe 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).
Change from baseline - Area of the lateral canal filled at 6 months and 1 year6 months and 1 year post treatmentThe study will also measure the area occupied by the filling material inside the lateral canal in relation to its entire area in mm²).

Secondary

MeasureTime frameDescription
Change from baseline - Periapical radiographic healing6 months and 1 year after endodontic therapyCompare 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
