Background: Irrigation during endodontic therapy is required in order to remove debris, tissue remnants, microbes and smear layer. Sodium hypochlorite (NaOCl) and Chlorhexidine (CHX) are the most commonly used irrigants. Although they are reported to have good antimicrobial effects, both have limitations. Hence, a combination of NaOCl and CHX has been proposed to compensate for these limitation...

This study aimed to describe a case report of endodontic treatment of a maxillary first molar with two roots and two palatal canals type I. The patient was referred to the Federal University of Pernambuco for endodontic treatment in left maxillary first permanent molar. After the clinical, physical and radiographic examination, the diagnosis was irreversible pulpitis. Radiographic examination s...

The mandibular canine is usually considered a single-rooted tooth with a single root canal. However, two canals and more rarely two roots may also occur. This paper reports the case of a patient with bilateral mandibular canines with two roots and two root canals. The initial periapical radiographs of the mandibular right and left canines for endodontic treatment revealed the presence of two ro...

Background A novel technique of sterilization of endodontic files is introduced in this article. Aims Newly introduced sterilization unit, named "SteriFast" is compared with autoclave and glass bead sterilizer using biological indicator. Materials and Methods Spore strips of Bacillus pumilus were cultured in nutrient broth. This cultured media was used to contaminate the experimental sample...

Aim. A new manufacturing method aiming at to producing more flexible and resistant NiTi endodontic instruments has been recently developed (Hyflex, produced with CM wire). The purpose of the study was to determine whether this new manufacturing method produces NiTi instruments (Hyflex) of superior flexibility and/or superior resistance to cyclic fatigue, when compared with instruments produced ...

Endodontic files come in contact with blood, infected pulp tissue, and irrigating solutions during root canal therapy. Some instruments such as stereomicroscopy and scanning electron microscopy are used to observe corrosion of endodontic files which are complicated and dependent on preparation methods. Having knowledge of the corrosion and ion release of endodontic files can help in drawing fir...
