AIM The aim of this study was to determine the frequency of two important pathogenic microorganisms associated with endodontic infections, Enterococcus faecalis and Candida albicans, in root canal samples from patients with necrotic pulps or failed canal therapy by polymerase chain reaction method. METHOD Microbial samples were obtained from 117 teeth with necrotic pulp tissues and 114 teeth ...

Context: Use of root canal solvents has increased the success rate endodontic retreatment and it made procedure faster simpler. Aims: During retreatment, a solvent facilitates removal obturation material sealer by softening it, so as to obtain free debris microorganisms. Hence an invitro study was done evaluate compare dissolving effect RC Solve, Eucalyptus oil G-sol on AH Plus Root Canal Seale...

Objective: The purpose of this study was to use confocal laser microscopy analysis evaluate the effectiveness conventional needle irrigation (CNI), EndoActivator (EA), and EDDY during endodontic retreatment.
 Methods: This included 45 maxillary incisor teeth with a single root canal. Root canals were prepared ProTaper Universal files (Dentsply Sirona, Ballaigues, Switzerland) obturated lab...

the root canal treatment (RCT) prognosis. The successful RCT prevents tooth loss and avoids pain and apical periodontitis. This review aimed to categorize common operative procedure errors and clinical factors associated with RCT. Based on this, will be approached common errors of procedures within the clinical operative sequence: endodontic treatment planning, pulp and periapical disease diagn...

The purpose of this study was to compare the efficacy of reciprocating and rotary techniques for removing gutta-percha and sealer from root canals. Forty straight and oval single-rooted premolars were prepared up to size 30, filled with gutta-percha and sealer, and then randomly allocated to two experimental retreatment groups: ProTaper Retreatment System (PTRS) and WaveOne System (WS). Procedu...

CASE REPORTS The problem of thermal sensitivity following non-surgical root-canal treatment is explored and case reports are presented. Possible causes for post-treatment discomfort from endodontic and restorative aetiologies are discussed, as are the mechanisms to explain the patients' painful experiences. Treatment of this problem may vary from the simple replacement of a defective restoratio...

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...
