statement of problem: failure of endodontic treatment is determined on the basis of radiographic findings and clinical signs and/ or symptoms of the treated teeth. purpose: the purpose of this study was to determine endodontic treatment failure in relation to various factors influencing it in teeth with periapical lesions (clinically and radiographically). materials and methods: teeth which had...

introduction: an important consideration in endodontic treatment is the elimination of microorganisms, including fungi, from the complex three- dimensional root canal system. candida albicans (ca) has a major role in endodontic treatment failure as the most important fungus isolated from the root canal system. the present study was carried out to evaluate the presence of ca in the teeth requiri...

INTRODUCTION Periapical inflammation is often responsible for distinct maxillary sinus (MS) changes. This retrospective, cross-sectional study evaluated the association between the clinical characteristics of periapical lesions (presence, size, and distance) in maxillary posterior teeth and the presence of sinus abnormalities by evaluating cone-beam computed tomographic (CBCT) images obtained f...

AIM To test the ability of periapical radiography (PA) and cone-beam computed tomography (CBCT) to determine the presence/absence of periapical lesions and examine the reliability of volumetric measurements of periapical lesions on CBCT scans. METHODOLOGY After tooth extractions in human mandibles, bone defects were cut at the base of extraction sockets to mimic periapical bone lesions. The t...

background & aim: according to presence of immune system factors in chronic periapical lesions, hypersensitivity reactions may have some role in pathogenesis of these lesions. up to now, among the factors participating in type i hypersensitivity reaction, only one of them has been studied. so the aim of this study was to evaluate the relationship between the presence of ige & number of mast cel...

The widespread use of oral implants in recent years has resulted in various types of complications. One of those complications is the periapical implant lesion. Different factors have been proposed to play a role in the development and emergence of a periapical implant lesion. To date, there is no consensus on the etiology and therefore periapical lesions around dental implants are considered t...

OBJECTIVE This article aims to determine the incidence of periapical granuloma from extracted teeth and correlate the clinical diagnoses with the histopathological types of periapical granuloma. PATIENTS AND METHODS Over a period of eight months, a prospective study designed as a routine biopsy of recoverable periapical tissues obtained from patients who had single tooth extraction was carrie...

Management of a tooth with open apex is a challenge to the dental practitioners. Evaluation of the periapical healing is required in such cases by radiographic techniques. The objective of this paper was to assess the healing of a periapical lesion in a non-vital tooth with open apex treated with mineral trioxide aggregate (MTA) obturation using cone beam computed tomography (CBCT). The endodon...

this case report presents conservative management of unset mineral trioxide aggregate (mta) after being placed as a root-end filling material following periapical surgery. periapical surgery was indicated for a maxillary lateral incisor of a 15-year-old male due to persistent exudate and a large periapical lesion. during surgery angelus mta was placed as root-end filling. the next session it wa...
