OBJECTIVES Correct determination of working length is an important step for success of endodontic therapy. Conventional radiography has limitations in providing the accurate location of apical foramen. For this reason, electronic apex locators (EALs) were developed to shorten the treatment time and decrease the radiation dose. The aim of this study was to evaluate the accuracy of Root ZX EAL fo...

INTRODUCTION The purpose of this in vitro study was to compare the accuracy of working length determination using the apex locator versus conventional radiography in C-shaped canals. METHODS AND MATERIALS After confirming the actual C-shaped anatomy using cone-beam computed tomography (CBCT), 22 extracted C-shaped mandibular second molars were selected and decoronated at the cemento-enamel ju...

Objective: To compare the accuracy of periapical radiography (PR) and cone-beam computed tomography (CBCT) for detection external apical root resorption (EARR) due to canal contamination. Material Methods: Dog’s teeth with experimentally induced contamination underwent or not treatment (n=62). True positives (TP), false (FP), true negatives (TN), (FN) in PR CBCT diagnoses were determined using ...

Apical periodontitis is primarily a consequences of root canal infection, be marked with inflammation and tissue destruction pe-riradiculars resulting from interactions between microbial factors the host immune response. This study aimed to evalu-ate prevalence chronic apical (CAP) inpatients Hasanuddin University Dental Oral Education Hospital during Covid-19 pandemic period in 2021. The was c...

An 83 year old woman presented to the emergency department with chest pain and dyspnoea. Chest radiography showed pneumothorax of the left lung. Arteries were normal on coronary angiography. Left ventriculography showed asynergy of apical akinesis and basal hyperkinesis. Within 18 days, the asynergy improved without any specific treatment. In the present case the left ventricular dysfunction ma...

OBJECTIVE To evaluate the periapical repair after root canal treatment in the teeth of dogs using CT and conventional radiography and to compare these findings with the gold standard microscopic evaluation. STUDY DESIGN The animals were divided into three groups according to endodontic treatment performed: Group 1, single-visit endodontic treatment in teeth without apical periodontitis; Group...

INTRODUCTION Conventional 2-dimensional radiography uses defined criteria for outcome assessment of apical surgery. However, these radiographic healing criteria are not applicable for 3-dimensional radiography. The present study evaluated the repeatability and reproducibility of new cone-beam computed tomographic (CBCT)-based healing criteria for the judgment of periapical healing 1 year after ...

introduction: the aim of this in vitro study was to evaluate the correlation between accuracy of root zx electronic foramen locator and root canal curvature. methods and materials: one hundred and ten extracted mandibular molars were selected. access cavity was prepared and coronal enlargement of mesiobuccal canal was performed. a #10 flexofile was inserted into the mesiobuccal canal, and a rad...
