BACKGROUND Apical periodontitis includes periapical granulomas and radicular cysts, which are histologically distinguished by the absence and the presence of an epithelial lining, respectively. The main cause of apical periodontitis is the bacterial colonization of the root canal space. This research aimed at assessing whether and how periapical granulomas and radicular cysts differ in terms of...

Among the odontogenic cysts, there are radicular cysts or also called periapical most common cyst. They develop at apex of a tooth with pulp necrosis, which may be consequence dental caries trauma. they asymptomatic, grow slowly, and discovered on routine radiographs. With proliferation ERM its activation, is an increase in osmotic pressure, causing cyst to expand, normally this not activated, ...

AIM To report the non-surgical management of a large periapical lesion. SUMMARY Surgical treatment of large periapical lesions is often subject to various complications. Hence, a non-surgical approach should be considered for the management of these lesions. The traditional aspiration technique involves creation of buccal and palatal wounds that can cause considerable discomfort for the patie...

The implant periapical lesion (IPL), a possible cause for implant failure, may occur from the presence of pre-existing microbial pathology such as endodontic/periodontal lesions. This case report presents a case history related to IPL, which was caused by a pre-existing endodontic lesion. In addition, other possible causes such as surgical trauma and the management strategies of IPL are suggest...

AIM The aim of the study was to quantify the presence of mast cells in various inflammatory lesions like periapical granuloma, periapical cyst, inflammatory gingival hyperplasia and pyogenic granuloma. Mast cell degranulation and association with lymphocytes were also recorded in an attempt to understand the role of mast cells in the pathogenesis of these inflammatory lesions. MATERIALS AND M...

BACKGROUND Periapical lesions (PLs) occur as a result of pulpal inflammation and may rarely be seen in the absence of pulpal diseases. They are the most common pathological lesions affecting the alveolar bone. OBJECTIVE This study aims to describe the clinicopathological features of PLs of the jaws with emphasis on the two most common types. METHODS Histopathology records of PLs diagnosed f...

This report presents a review of results from 2370 biopsies of patients up to 20 years of age received over 11 years in the biopsy service at the University of Illinois at Chicago. The computerized data were retrieved and compiled for site, age, sex, race, and diagnosis of the biopsies. The lesions were divided into 1) inflammatory and reactive, 2) cystic, 3) neoplastic, and 4) other anomalies....

Periapical tissue from 58 cases requiring periapical surgery was examined histologically and cultured for the presence of microbes. Twenty-nine had a possible oral cavity communication and 29 did not. Approximately one-half of each biopsy was submitted for culture while the other portion was examined histologically. Cultures were positive for the presence of bacteria in 51 of 58 cases while bac...
