Aims: To evaluate the volumetric amount of endodontic obturating materials remains after retreatment with and without complementary retreatment(XP-Endo Finisher) utilizing two rotary systems (R-Endo EdgefileXR).Materials Methods: Twenty human mandibular premolars single straight root canals were prepared using a 2Shape system file size 25/0.04. Gutta-percha T-Seal (Epoxy resin sealer) used to o...

The aim of this study was to evaluate the effect using a higher rotation speed with XP-endo Shaper (XPS) on apically extruded debris and operation time during endodontic treatment retreatment procedures. Sixty mesial roots mandibular first molar teeth were randomly assigned four groups (Initial groups: XPS used at 1000 or 3000rpm speeds Retreatment speeds). During initial procedures preweighed ...

Introduction The aim of this study was to evaluate the incidence of dentinal defects and vertical root fractures (VRFs) after endodontic retreatment and mechanical cycling (MC). Methods and Materials Two hundred mandibular premolars were selected. Forty teeth were left unprepared (control group). The remaining 160 root canals were prepared with ProTaper instruments and filled by using two dif...

A 48-year-old male patient presented to the Department of Endodontics for evaluation of right first permanent molar, which had received non-surgical root canal treatment two years ago and was restored with core material. The presenting symptoms included swelling in the buccal vestibule and pain overnight. Clinical examination demonstrated that the mandibular right first molar was sensitive to p...

This article describe a rare case of multiple taurodontism involving all molars in a 17-year-old male. Volumetric cone-beam computed tomography was used to investigate internal and external root morphology, including that of a maxillary first molar which required endodontic treatment and retreatment. Medical history was not contributory; however, Klinefelter syndrome was the diagnostic hypothes...

Removing posts from root canals prior to endodontic retreatment is often a challenge. The Gonon post removing system (Thomas Extracteur De Pivots; FFDM-Pneumat, Bourges, France) is safe and efficient and can be used for anterior, bicuspid, and even molar teeth. The Gonon system is illustrated with one clinical case.

Large apical radiolucencies after endodontic treatment are usually advised orthograde retreatment, apical surgery and that too with a guarded prognosis. Microsurgical techniques, the use of ultrasonic and magnification aides, have been in use in the developed countries for the past few decades and have shown significant improvement in long-term success of such cases. MTA is proposed as one of t...

History Presenting complaint – persistent dull pain arising from the upper right area of the mouth. History of complaint – Mr DS complained of a well localised, moderate, but constant dull ache arising from the right maxillary first molar (UR6). This started nine months ago following an acute episode that was managed by his GDP with antibiotics and is exacerbated only by masticatory forces with...

INTRODUCTION Little is known about the frequency of persistent pain after endodontic procedures even though pain is a core patient-oriented outcome. We estimated the frequency of persistent pain, regardless of etiology, after endodontic treatment. METHODS Persistent tooth pain was defined as pain present > or = 6 months after endodontic treatment. Endodontic procedures included in the review ...
