Background and Aim: Since the external root resorption is not detectable clinically, therefore radiographic examination is very important for diagnose, Therefore, the purpose of this study is to compare the diagnostic efficiency of conventional, digital and CBCT radiography in detecting of external root resorption. Materials and Methods: In this descriptive-analytic study, after radiographic a...

INTRODUCTION The aim of this study was to compare the diagnostic value of cone-beam computed tomography (CBCT) and periapical (PA) radiography in detecting internal root resorption. METHODS AND MATERIALS Eighty single rooted human teeth with visible pulps in PA radiography were split mesiodistally along the coronal plane. Internal resorption like lesions were created in three areas (cervical,...

o bjectives: correct determination of working length is an important step for suc- cess 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 ea...

Practitioners face several challenges during the root canal treatment of teeth with wide or immature apices, one of which is working length determination. There is relatively little data regarding the value of radiography and electronic apex locator (EAL) use when root formation is incomplete, and supplementary measurement techniques may be helpful. This review considers length determination fo...

Statement of Problem: Radiography is the most common technique in working length determination, however, because of its limitations is not considered as an ideal technique. Its application, particularly for children due to radiation hazards, technical problems in young and unco-operative children and the superimposition of permanent teeth bud on primary teeth root, lead to numerous problems.Pur...
