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...

Intrusive luxation is a serious dental injury that causes damage to the pulp and supporting structures of a tooth because of its dislocation into the alveolar process. This paper presents the case of the re-eruption of a severely intruded immature permanent incisor with a crown-root fracture. A 9-year-old boy was referred to the clinic 1 day after a fall. Clinical and radiographic examinations ...

Root canal filling materials, including sealercement and obturation points or cones, are used in root canal treatment to occlude the apical portion of the canal. These will block the dentinal tubules preventing passage of tissue fluids, toxins, and microorganisms into the root canal space. Many investigators have demonstrated the importance of a sealer cement for effective root canal obturation...

introduction: various materials and methods have been recommended for successful root canal obturation. the aim of this experimental in vitro study was to compare the sealing ability of three root canal sealers ah-26, glass ionomer cement (gic) and zinc oxide eugenol (zoe) in single gutta-percha obturating system. methods and materials: seventy extracted single-rooted human teeth were decoronat...

Background:One of the main reasons for extraction of endodontically treated teeth is vertical root fracture (VRF). Some factors such as root canal treatment are involved in vertical root fracture because of their potential to weaken the tooth structure. Therefore, this study aimed to investigate the effect of combining different obturation materials and rotary systems on the fr...

Introduction: The technique of single-cone obturation is a technique that uses only the master cone. There have been an increase in its use, especially by employing larger cones with larger taper sizes that best match the geometry of rotary nickel-titanium systems (NiTi), not requiring the use of accessory cones, thus reducing the time spent in endodontic obturation. Objective: To review the li...

INTRODUCTION One of the key factors in successful endodontic therapy is to adequately fill the root canals. The aim of this in vitro study was to compare the quality of four different root canal obturation techniques: cold lateral condensation (CLC), warm vertical condensation (WVC), Obtura II (OII) and Gutta Flow (GF) by using micro-computed tomography (micro CT). MATERIALS AND METHODS A tot...

The complex anatomy of the root canal system takes up many configurations and variations are not uncommon. A clinician should be aware of the normal, so as to recognize these aberrations in the anatomy. Successful root canal therapy is achieved by thorough shaping and cleaning of the root canal system followed by obturation of the radicular space. The aim of the present article is to describe a...

the main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. failure to find and fill a canal contributes toward the failure of endodontic therapy .the root canal anatomy of mandibular first molars is complex. studies of the morphologic structure of root canal systems have d...
