Periapical inflammatory responses occur as a consequence of bacterial infection of the dental pulp, as a result of caries, trauma, or iatrogenic insult. Periapical inflammation stimulates the formation of granulomas and cysts, with the destruction of bone. These inflammatory responses are complex and consist of diverse elements. Immediate-type responses--including vasodilatation, increased vasc...

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...

in patients with malignancy, the common etiologies of granuloma formation are tumor related sarcoid reaction, sarcoidosis, tuberculosis and other granulomatous diseases. often, the finding of granulomas in malignant patients may obscure the primary malignancy or may mislead towards treatment of infectious and other etiologies. hence, their proper recognition and necessary follow up is needed to...

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...

Cone beam computed tomography (CBCT) is a recent three-dimensional (3D) radiographic imaging modality used for the accurate diagnosis, management and follow-up of endodontic problems. In tooth with open apex and periapical lesion, the use of new obturation material such as white mineral trioxide aggregate (wMTA) facilitates faster and more predictable closure of root apex and periapical healing...

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...
