The microbiology of periapical granulomas
Oral Surgery, Oral Medicine, Oral Pathology, 1990Of the 16 periapical granulomas studied, 14 (88%) yielded a positive growth when homogenized and cultured. The concentration of colony-forming units per milliliter of the suspension ranged from 10(1.3) to 10(4.0) (mean 10(2.2)). A total of 47 isolates comprising 26 (55%) facultative anaerobes and 21 (45%) strict anaerobes were obtained.

Midkine Expression in Human Periapical Granulomas
Journal of Endodontics, 2011The expression of midkine (MK), a heparin-binding growth factor, is increased in various human tumors, making it a promising tumor marker and target for tumor therapy. MK is also related to the regulation of the development and etiology of chronic or autoimmune diseases; however, the involvement of MK in apical periodontitis has never been examined ...

Periapical granuloma associated with extracted teeth
Nigerian Journal of Clinical Practice, 2011This article aims to determine the incidence of periapical granuloma from extracted teeth and correlate the clinical diagnoses with the histopathological types of periapical granuloma.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 ...

Periapical granulomas and cysts
European Journal of Oral Sciences, 1970Abstract— A clinical and radiographic study was undertaken on 1,600 periapical lesions from 1,133 patients referred for extractions or apicoectomies. The clinical findings as well as the radiographic size (diameter) of the lesions were recorded. When this diameter measured less than 5 mm, the pathologic tissue was left in the bone after extraction ...

The tuberculous dental periapical granuloma
American Journal of Orthodontics and Oral Surgery, 1943I N THE early part of 1936, an investigation was begun at Sea View Hospital, in New York City, to study the periapical granuloma in patients afflicted with tuberculosis. It was felt that some of these blind abscesses might be specific tuberculous lesions.

Histological findings of human leprosy periapical granulomas
Journal of Endodontics, 1996Histological analysis of human leprosy periapical granulomas was conducted to study the histological responses to Mycobacterium leprae. Many Langhans-type giant cells and epithelioid cell tubercles were observed, although M. leprae were not detected in leprosy periapical granulomas.

Immunoglobulin producing cells in human periapical granulomas
British Journal of Oral Surgery, 1983Ten cases of periapical granuloma were stained for igG, IgA, IgM, IgD and IgE by the unlabelled antibody peroxidase-antiperoxidase complex method to investigate the class distribution of plasma cells within the lesions. The results indicated that IgG containing plasma cells predominated in all lesions and that IgG, IgA, IgM, IgE and IgD cells ...

Touton-like giant cells in periapical granulomas
Journal of Endodontics, 1989Two types of multinucleated giant cells were observed in periapical granulomas--the foreign body type and the Touton type. In the Touton type, the nuclei were near the center of the cell, surrounded by foamy cytoplasm. Both types of giant cells reacted positively to lysozyme, alpha 1-antitrypsin and alpha 1-antichymotrypsin, indicating their ...

Radiological Interpretation of the Periapical Cysts and Granulomas
Dentomaxillofacial Radiology, 1982The radiographs of 88 histologically verified periapical lesions were re-evaluated to assess the validity of the diagnostic criteria applied to differentiate cysts and granulomas. In addition, the localization of the lesions was registered. Of the total series, 60 lesions proved to be cysts, and 28 were granulomas.

Heparanase expression in periapical granulomas and radicular cysts
Odontology, 2011Heparanase is an endo-β-D-glucuronidase enzyme which degrades heparan sulfate glycosaminoglycan side chains of proteoglycans in the extracellular matrix and in basement membranes. The aim of this study was to evaluate the expression of heparanase in periapical granulomas (PGs) and radicular cysts (RCs).
