a detailed knowledge of root canal anatomy is a prerequisite for successful endodontic treatment. such information is highly dependent upon the ethnicity of the population of interest. lack of sufficient national information concerning internal anatomy can lead clinicians to increase their rate of treatment success. the aim of this study was to evaluate external root morphology and root canal a...

accurate diagnosis of the root canal morphology and anatomy is essential for thorough shaping and cleaning of the entire root canal system and consequent successful treatment. this report describes a case of maxillary second premolar with two roots and three root canals (two mesial and distal palatal canals). the case report underlines the importance of complete knowledge about root canal morph...

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...

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...

introduction: bacteria and their byproducts are major etiologic factors in endodontic diseases. prevention or reduction of root canal bacterial contamination is the main aim of endodontic treatment. the purpose of this in vitro study was to evaluate the effect of size and taper of master apical file (maf) in reducing bacteria from the apical third of the curved canals using a quantitative scann...

accumulation of soft tissue or dentinal remnants in the apical region is a common event that can cause blockage of root canals. this event can be avoided if apical patency is performed during the root canal shaping procedures. however, there is no consensus on the role of apical patency in relation to the success of endodontic treatment of necrotic teeth with apical periodontitis. therefore, th...

The main objectives of root canal treatment are thorough shaping and cleaning of all pulp spaces and its complete obturation with an inert filling material. The presence of untreated canal may be a reason for failure of endodontic therapy. To achieve satisfactory root canal therapy, a proper and in-depth knowledge of complex and abnormal root canal morphology is essential.

conclusion the cbct may be safe to use in determining root canal wl. because lower radiation dose, a pre-existing cbct can be useful to detect the root canal wl more precisely. results the cbct was the most accurate method to evaluate the root canal wl, with accuracy of 70%. accuracy for the apex locator and periapical radiograph were 40% and 30%, respectively. materials and methods totally, 30...

conclusion the determination of the presence of mb2 in the maxillary first molars may be carried out using cbct scans. if the ∠mdp was 91 degrees or greater, there was considered to be a higher probability that mb2 canals would be found in the endodontic cavity. due to the positive correlation between the ∠mdp and the ∠mdmb2, the localization of mb2 canals may be easily performed in relation to...
