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 to...

introduction: the purpose of this study was to evaluate external root surface temperature rise during post space preparation using la axxess bur, beefill pack system, and peeso reamer drill. materials & methods: the distal canals of forty-five extracted human permanent mandibular first molars were instrumented in crown-apical manner and obturated with lateral condensation technique. teeth were ...

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 ...

PURPOSE This study evaluated the prevalence of distolingual roots in mandibular molars among Koreans, the root canal system associated with distolingual roots, and the concurrent appearance of a distolingual root in the mandibular first molar and a C-shaped canal in the mandibular second molar. MATERIALS AND METHODS Cone-beam computed tomographic images of 264 patients were screened and exami...

HYBROSONIC : The name derives from Heat + Sonic Vibration. The invention relates to Root Canal Obturating Device for fillling of Root Canal after removal of tooth pulp. Root canal treatment is the removal of tooth’s pulp, a small thread like tissue in the centre of the tooth. Proper root canal filling should achieve three dimensional obturation of the root canal space to prevent micro organisms...

Success in root canal treatment is achieved after thorough cleaning, shaping, and obturation of the root canal system. This clinical case describes conventional root canal treatment of an unusual mandibular first molar with six root canals. The prognosis for endodontic treatment in teeth with abnormal morphology is unfavorable if the clinician fails to recognize extra root canals.

Root canal irrigants play a significant role in the elimination of microorganisms, tissue dissolution, and the removal of debris and smear layer. Sodium hypochloride is the most commonly used endodontic irrigant, despite limitations. None of the presently available root canal irrigants satisfy the requirements of ideal root canal irrigant. Newer root canal irrigants are studied for potential re...

Introduction This in vitro study was designed to evaluate and compare different endodontic irrigation and activation systems for removal of the intracanal smear layer. Methods and Materials Forty recently extracted, non-carious human intact single rooted premolars were selected and divided into five groups (n=10) according to the root canal irrigation systems; syringe and needle irrigation (C...

Background. The tubular penetration and adaptation of the sealer are important factors for successful root canal filling. The aim of this study was to evaluate the tubular penetration depth of four different sealers in the coronal, middle, and apical third of root canals as well as the adaptation of these sealers to root canal walls. Materials and Methods. 50 single-rooted teeth were prepared i...

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...
