简要总结
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.
详细描述
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.

结局指标
主要结局
Change from baseline - Area of the lateral canal filled at 6 months and 1 year
时间窗: 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).
Change from baseline - Size of the lesion in the lateral canals at 1 year
时间窗: 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.
Change from baseline - Length of lateral canal filled at 6 months and 1 year
时间窗: 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).
次要结局
- Change from baseline - Periapical radiographic healing(6 months and 1 year after endodontic therapy)
