BACKGROUND Analyze the most important prognostic factors when performing periapical surgery and compare the success rates of distinct authors. INTRODUCTION Periapical surgery is an approach to treat non-healing periapical lesions and it should be viewed as an extension of endodontic treatment and not as a separate entity. MATERIAL AND METHODS A search of articles published in Cochrane, PubM...

The presence or absence of periapical radiolucencies, after a predetermined healing period, have been used as a criteria for therapeutic success or failure in endodontic treatment. However, in radiologic diagnosis it has been shown that variations within and between examiners are substantial. In the present study six endodontists evaluated the periapical tissues in radiographs of 119 endodontic...

Abstract The aim of this article is to discuss the sequelae a missing tooth from normal series dental arch and importance cone beam computed tomography (CBCT) in diagnosis treatment planning such cases. We also correlate position an impacted maxillary premolar as seen on panoramic radiography with CBCT. Routine imaging modalities like intraoral periapical, occlusal, view often give inadequate i...

AIM To investigate the probability of and factors influencing periapical status of teeth following primary (1°RCTx) or secondary (2°RCTx) root canal treatment. METHODOLOGY This prospective study involved annual clinical and radiographic follow-up of 1°RCTx (1170 roots, 702 teeth and 534 patients) or 2°RCTx (1314 roots, 750 teeth and 559 patients) carried out by Endodontic postgraduate student...

Context: The essential role of a general dental practitioner is recognizing the nature of the oral cavity lesions. Periapical lesions, which are observed in radiographs of patients, may have odontogenic or nonodontogenic origins. This review aimed to study differential diagnosis of common and important periapical lesions. Evidence Acquisition: English-language literature were searched by manual...

IntroductionThe aim of this study is to report the management of large periapical lesion using triple antibiotic paste as an alternative intra-canal medicament in nonsurgical endodontic treatment. Case reportan 11 year old male patient with large periapical lesion in mandibular anterior region, treated using conservative non-surgical endodontic treatment. Calcium hydroxide-iodoform paste (Vitap...

The aim of this study was to examine morphologically the participation of extraradicular biofilm in refractory periapical periodontitis. Six teeth and five extruded root filling gutta-percha points associated with refractory periapical periodontitis were investigated by scanning electron microscope. In nine of 11 samples examined, bacterial biofilms were seen at the extraradicular area. The gut...

Pulpitis results in significant morbidity among the elderly, particularly in underserved communities. We collected panoramic oral radiographs from 244 (mean age 67) participants of the Northern Manhattan Study, a prospective cohort study of stroke risk in a multiethnic urban population. Radiographs were evaluated for missing teeth, caries, restorations, periodontal bone loss, adequacy of endodo...

Segmentation on the trabecular of dental periapicalX-Ray images is very important for osteoporosis screening. Existing methods do not perform well in segmenting the trabecular of dental periapical in X-Ray images due to the presence of large amount of spurious edges. This paper presents a combination of tophat-bothat filtering, histogram equalization contrasting and local adaptive thresholding ...

OBJECTIVES The aim of the present study was to compare the accuracy of intraoral digital periapical radiography and cone beam computed tomography in the detection of periapical radiolucencies in endodontically treated teeth. MATERIAL AND METHODS Radiographic images (cone beam computed tomography [CBCT] scans and digital periapical radiography [PR] images) from 60 patients, achieved from Septe...
