The amounts of apical enlargement have been a controversial issue for a long time. The enlargement of the apical part of the canal may severely impact the endodontic prognosis. Enlargement of the apical portion to a larger size may negatively affect the ability to control the filling material during root canal obturation. In addition, an open-apex increases the risk for overfilling which has be...

BACKGROUND Internal inflammatory root resorption is a rare condition in permanent teeth, which requires the presence of necrotic and infected pulp tissue within the coronal portion of the root canal system as well as inflamed pulp tissue apical to the resorptive defect. The aetiology of internal root resorption is not completely understandable, trauma and chronic pulpitis are considered the mai...

AIM To compare the use of periapical radiographs and digital panoramic images displayed on monitor and glossy paper in the assessment of the periapical status of the teeth using the periapical index (PAI). METHODOLOGY A total of 86 subjects were examined. All participants underwent a full-mouth radiographic survey (14 periapical radiographs) and a panoramic radiography. The periapical status,...

BACKGROUND Traditional radiography is limited in its ability to give reliable information on the number and morphology of root canals. The application of cone-beam computed tomography (CBCT) provides a non-invasive three-dimensional confirmatory diagnosis as a complement to conventional radiography. The aim of this study was to evaluate the root and canal morphology of mandibular premolars in a...

INTRODUCTION External root resorption (ERR) is associated with physiological and pathological dissolution of mineralized tissues by clastic cells and radiography is one of the most important methods in its diagnosis. The aim of this experimental study was to evaluate the accuracy of conventional intraoral radiography (CR) in comparison with digital radiographic techniques, i.e. charge-coupled d...

abstract introductiion. there are a lot of edentulous patients who need complete dentures in any society. one of the most important problems of edentulous patients is remaining dental lesions. atrophy of maxillary or mandibular bone, infections abcesses, tumors and so on are among some other problems. in this study we tried to evaluate the panoramic radiography in order to detect these problems...

The elimination of necrotic and inflamed pulp tissue, dentin debris, microorganisms is essential for the success endodontic treatment. However, root canal’s complexity has led to incomplete cleaning disinfection. This study aims compare efficacy penetrability three different irrigation activating techniques apical third canal. Sixty sound single-rooted human mandibular premolars are prepared wi...

The subject matter of the article is X-ray images teeth during endodontic operations. goal work to compare developed method segmentation radiograph determine length root canal with electrometric and mathematical methods in practice. uses following methods: principles preparation teeth; determining working (radiological, electrometric); threshold method; bone structures on tomographic images. re...
