introduction: the purpose of this study was to determine the effects of citrus aurantifolia (ca) extract on smear layer removal in different parts of root canals. materials and methods: thirty-nine single-rooted human teeth were randomly divided into three experimental ( n =12) and one control ( n =3) groups. teeth were instrumented using mtwo rotary instruments. root canals were irrigated with...

abstract: cone-beam computed tomography (cbct) has been accepted as a useful tool for diagnosis and treatment in endodontics. despite a growing trend toward using cbct in endodontic practice the cbct images should be interpreted carefully. this case report presents a case that showed radiolucency inside and around a tooth which was free of pathologic changes under a dental operative microscope ...

a mandibular first molar requiring root canal therapy was found with five canals, three mesial canals, and two distal canals. initially, four canals (mesiobuccal, mesiolingual, distobuccal, and distolingual) were identified. the mesiobuccal and mesiolingual canals were found in their normal locations, and a fifth canal was noted between these two. this case demonstrates a rare anatomical config...

introduction: the aim of this study was to gather information on the materials and methods employed in root canal treatment (rct) by general dental practitioners (gdps) in iran. methods and materials: a questionnaire was distributed among 450 dentists who attended the 53 th iranian dental association congress. participants were asked to consider demographic variables and answer the questions re...

introduction: despite being the gold standard as well as a routine technique in endodontics, radiographic working length (wl) determination owns many drawbacks. electronic apex-locators (eals) are recommended to complement radiographies. the aim of this study was to evaluate the perceptions of iranian general dental practitioners (gdps) towards using radiography and eal. methods and materials: ...

this article describes a clinical case of mandibular second premolar with three separated canals in apical third of the root that are diagnosed and endodontically treated. sound knowledge of root canal anatomy and morphology, tactile examination of canal walls, critical interpretation of radiographs and high magnification examination are essential elements of success in complicated root canal t...

Abstract: Human maxillary first molars are usually considered as three-rooted teeth with four root canals for the presence of a second canal in the Mesio Buccal root (MB2). In addition, lateral ramifications and apical delta of the root canal system may frequently occur, increasing the probability of leaving untreated spaces after the root canal therapy. A thorough knowledge of root canal mor...

most mandibular second molars have one and two canals in distal and mesial roots, respectively. this report represents four cases of mandibular second molars with a single mesial and two distal root canals with two different canal configurations. after access cavity preparation, two teeth had one distal and two mesial orifices, whereas in the two other teeth one mesial and two distal orifices w...

BACKGROUND AND AIM: The primary providers of health services are general dental practitioners (GDPs), who must routinely do the diagnosis and treatment planning except in complicated cases. The present study evaluation of a referral system to endodontists among a group of GDPs in Iran. METHODS: This descriptive study was performed on 620 Iranian general dentists. A questionnaire with an accepte...

Endodontic therapy of mandibular molars is a challenging task due to its varied root canal morphology. A mandibular first molar with additional buccal root (Radix paramolaris) and additional distolingual root (Radix Entomolaris) is an example of its varied anatomy. A successful management of atypical root canal configurations is an important aspect in determining the success rate of root canal ...
