The endodontic triad comprises of cleaning and shaping, disinfection and obturation. Success of root canal therapy is majorly achieved by proper cleaning and shaping. However, elimination of bacterial contaminants as well as necrotic debris of the canals requires the adjunctive use of irrigants. To achieve a satisfactory biological and mechanical preparation proper selection of endodontic instr...

The major goal of root canal treatment is to remove irritants from the root canal system, to obturate the cleaned and shaped root canals, and to prevent recontamination. Ray and Trope proposed that coronal microleakage may be a major cause of endodontic failure. Many previous studies have examined that coronal leakage might occur, even in well obturated root canals. One of the most important co...

Successes of endodontic treatment depend on cleaning and shaping of root canal and adequately obturate the prepared root canal space. 1-3 Obturation has historically been achieved with gutta percha and a sealer. The root canal system has many variations in anatomy such as irregularly shaped canals, lateral and accessory canals, anastomoses between canals and a variety of fins. All this leads to...

UNLABELLED The failures of root canal preparation are due to some anatomical deviation (canal in "C" or "S") and some technique errors. The technique errors are usually present in canal root cleansing and shaping stage and are the result of endodontic treatment objectives deviation. OBJECTIVES Our study was made on technique errors while preparing the canal roots with hand ProTaper. METHODO...

BACKGROUND AND AIM: Root canal treatment, especially in curved and constricted root canals, can be very difficult and time consuming. Several investigations have compared the reciprocating and full sequence motions in terms of shaping ability. The purpose of the present study was to compare the root canal transportation and centering ability of RECIPROC and iRace using cone-beam computed tomogr...

INTRODUCTION Cleaning and shaping without making procedural errors have always been a challenge in endodontics, particularly when the root canals are curved. Several rotary instruments have been developed to minimize such errors. The purpose of this study was to compare the shaping ability of 2 rotary file systems, BioRace (BR; FKG, La Chaux-de-Fonds, Switzerland) and ProTaper Next (PTN; Dentsp...

intRODuCtiOn The self Adjusting File (sAF*) system is a new approach to shaping root canal systems, which does not use solid metal files. (Fig 1). The sAF relies on the gentle abrasive action of a flexible mesh lattice to prepare the root canal walls. The sAF offers: 1) the ability to instrument and prepare complex-shaped root canal anatomies; 2) the capability to provide continuous and efficie...

instrument fracture within the root canal during root canal treatment is an unwanted and frustrating complication. the fractured segment may hinder cleaning and shaping procedures with potential impact on prognosis of treatment. fracture of endodontic instrument often results from incorrect use or overuse. if breakage occurs clinically, the patient should be informed of the incident and conside...

For the successful root canal treatment, thorough cleaning and shaping of the root canal system is a necessary procedure. C-shaped canals are known to have a complex canal anatomy with numerous fins connecting individual canals, thus require supplementary effort to accomplish a successful root canal treatment. Generally, anthropologic differences in tooth shape is not an important issue in the ...

Meticulous cleaning, shaping and filling of the root canal system are requisites for a successful root canal treatment.. Unfortunately, canal preparation is adversely influenced by the highly complex, intricate and variable root-canal anatomy. Thorough knowledge of root canal morphology and unusual anatomy of the tooth is crucial for the practitioner. Over the years, there have been numerous st...
