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.

Conditions

• Root Canal Infection

Interventions

Type	Name	Description
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.
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).
