INTRODUCTION Endodontic retreatment is a complex intervention that requires detailed analysis of possible reasons for failure, and flawless practical execution of the procedure. OBJECTIVE The aim of the study was to assess the outcome of endodontic retreatment based on clinical and radiographic criteria after a two-year observation period. METHODS Clinical study included 49 teeth indicated ...

INTRODUCTION Teeth undergoing initial endodontic therapy have a very high survival rate. Some teeth that continue to show signs of pathosis after the initial therapy will require nonsurgical (orthograde) retreatment. Outcome assessment of endodontic retreatment is crucial for appropriate case selection and treatment planning. However, reports on outcomes of orthograde endodontic retreatment per...

OBJECTIVE The goal of present study was to determine the effect of different nickel-titanium file systems on the amount of apically extruded debris during endodontic retreatment: D-RaCe retreatment systems, EdgeFile XR retreatment rotary files, and Reciproc R40. MATERIALS AND METHODS Thirty-six single-rooted prepared mandibular premolar teeth were filled with Gutta-percha and AH Plus sealer. ...

Endodontic therapy has a high survival rate, but in cases of post-treatment pathosis, retreatment may be required. This case report presents a similar case of endodontic failure which resulted in a coexistent periradicular-periodontal lesion. The case was managed by nonsurgical endodontic retreatment followed by photodynamic therapy in the periodontal region. Satisfactory results were obtained ...

INTRODUCTION The failure of primary endodontic treatment is manifested by various clinical symptoms following endodontic therapy or, more frequently, by the development of chronic inflammatory process in the apex region without any subjective symptoms. In case of unfavorable outcome of the primary endodontic treatment, orthograde endodontic retreatment is the method of choice for a prolonged th...

The purpose of this article was to illustrate an alternative approach to non-surgical management of teeth with failed surgical retreatment. The patient presented with complaint of severe pain after endodontic treatment of the maxillary right lateral and central incisors, which has not been reduce by periradicular surgery. Radiographic examination revealed the poor quality of both the endodontic...

Aim and Objective: Endodontic retreatment is indicated in the event of a failure initial treatment root canal an that looks to be correctable with retreatment. This in-vitro study was designed assess efficacy passive ultrasonic irrigation endodontic retreatment, by employing scanning electron microscopes, on cleanliness dentine tubules without solvent curved channels. Material method: Sixty hum...

Introduction: Working length determination is important in successful endodontic treatment and retreatment.This study evaluated the accuracy of two electronic apex locators Root ZX and Raypex®6 (EALs) in determining the electronic working length (EWL) of the root canals in endodontic treatment and retreatment. Materials and Methods: Access cavities were prepared on forty extracted, singl...
