BACKGROUND AND AIM: Inflammatory Periapical lesions are the most common periapical lesions. These lesions are often diagnosed based on clinical and radiological examination, which may be different from the histological finding. The present study was carried out with aim to assess the rate and to compare clinical and radiographic features with histological diagnosis of periapical pathology.METHO...
Background and purpose: Periapical inflammatory lesions are localized periapical bone reactions that result from pulp necrosis and inflammation or periodontal diseases. Inappropriate treatments are often considered as one of the main factors associated with apical periodontitis. This study was done to evaluate periapical radiolucencies in panoramic radiographs. Materials and methods: In this c...
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 AND AIM: Intra-osseous pathologic lesions of the jaw bones have different radiological and clinicopathological features from benign to malignant lesions. The aim of this study was to determine the prevalence of jaw lesions in Isfahan, Iran, during 1992-2017. METHODS: In this descriptive-analytical study, all re...
This article reports non-surgical endodontic retreatment of two patients with persistent or recurrent periapical lesions, who had previously undergone surgical and non-surgical endodontic therapy respectively. It further discusses and reviews the relevance of classification of periapical lesions, the explanation behind healing of periapical lesions by endodontic therapy alone, causes of persist...
conclusions the authors recommended to have paraclinical tests, especially vitality tests, in addition to clinical and radiographic examinations to avoid endodontic mistreatment. in suspicious cases, biopsy of lesions, referral to pathologist, and long-term fallow-up is required. context the essential role of a general dental practitioner is recognizing the nature of the oral cavity lesions. pe...
background periapical lesions are induced in response to injuries to periapical tissues, which are generally the result of infections within the root canal. mast cells actively participate to the inflammatory infiltration of periapical granulomas and cysts. objectives the aim of this study was to detect and compare the presence of mast cells in inflammatory periapical lesions, including cysts a...
Background and purpose: Periapical diseases are the result of untreated pulpitis or inadequate treatment of root canals. This study aimed to investigate the prevalence of different periapical lesions according to demographic variables in patients attending the departments of oral pathology in Mazandaran province, Iran 2012 to 2017. Materials and methods: In this cross-sectional descriptive stu...
Periapical diseases are induced as a result of the direct or indirect involvement of oral bacteria. The etiologic factor being the degenerating pulp tissue. A periapical lesion is formed within an area of apical periodontitis which cannot form by itself and is inflammatory in origin. If the microbial etiology of periapical lesions and in the root canal is removed by nonsurgical root canal thera...
