Active clinical trials for "Tooth, Nonvital"

The purpose of this randomized clinical trial was to evaluate the incidence of postoperative pain after root canal treatment using different final irrigation protocols. Patients whom need root canal treatment for first time were included. The presence of postoperative pain was assessed after root canal treatment cases at 12, 24, 48, 72 hrs and 1 week.

Objectives: The aim of this study was to assess postoperative pain in prospective randomized clinical trial comparing Reciproc or hand instrument and also different obturation techniques in one visit of endodontic retreatment. Conventional root canal treatment was done to 45 patients who needed retreatment. All instruments used in this study are routinely used instrument in endodontic therapy. After completed root canal treatment, the patients asked the intense of post operative pain.

The aim of this study is to evaluate the clinical performance of lithium disilicate crowns restoring endodontically treated teeth with two occlusal preparation schemes.

Postoperative pain in endodontic retreatment cases presents a challenge to any endodontist. Tricalcium silicate materials as mineral trioxide aggregate (MTA) and bioceramics have shown favorable periapical tissue reactions and healing when used as part of the root canal filling material. This study was conducted to compare the difference in the postoperative pain when resin cements are used versus bioceramic cements in the obturation of root canals.

The present clinical trial will be conducted to reject or accept the null hypothesis that in endodontically treated posterior teeth with deeply located proximal margins, will the Deep Margin Elevation will have better results from surgical crown lengthening in terms of biological criteria?

This clinical trial will be conducted to evaluate the amount of Il-8 expression before and after the application of intracanal irradiation with diode laser 980 nm versus placebo in failed endodontic cases with periapical lesions.

The study compares the prognosis of cases of Separated Instruments in Canals With Type II Vertucci's Classification treated with conservative approach

The aim of this study was to evaluate and compare postoperative pain and overextension of root canal filling after root canal treatment using a carrier-based obturation system and two different sealers. In this prospective randomized clinical trial, 160 mandibular premolars and molars in 160 patients were treated. Patients with vital and devital teeth were assigned to four groups using a randomized block design with block sizes of 10 patients each. The groups were composed of devital teeth with periapical lesions treated with iRoot SP sealer, vital teeth treated with iRoot SP sealer, devital teeth with periapical lesions treated with AH Plus sealer, and vital teeth treated with AH Plus sealer. In single visits, a single operator prepared root canals and filled them with sealer using the carrier-based obturation technique. Radiographs were taken and obturation length was recorded. Patients recorded pain scores use of Visual Analogue Scale and frequency of analgesic intake at baseline and 0-6, 6-12, 12-24, and 24-72 h..

In patients with endodontically treated teeth, will the Indirect Milled composite Endo-crown restorations have a better clinical performance and more wear resistance than the Direct Bulk-Fill resin composite restorations over one year? Primary Objective: To evaluate clinical performance of different Techniques of Composite Restorations (Indirect restorations using a CAD/CAM grinding process, BRILLIANT Crios, Coltène/Whaledent AG, Switzerland or Direct a light-cured, bulk-fill nanocomposite restorative material, Filtek™ One Bulk Fill Restorative, 3M ESPE Dental Products, USA) in Endodontically treated posterior teeth.

The aim of this randomized clinical trial was to compare the incidence, intensity and duration of postoperative pain following the removal of root canal obturation materials canals using rotary (ProTaper Universal or Hyflex EDM) or reciprocating file (Reciproc Blue or WaveOne Gold) systems. The null hypothesis tested was that there is no difference in postoperative pain following the retreatment procedure between the four systems used.
