Enterococcus faecalis Extracellular Vesicles Promote Apical Periodontitis

Journal of dentistry research
Enterococcus faecalis is an important contributor to the persistence of chronic apical periodontitis. However, the mechanism by which E. faecalis infection in the root canals and dentinal tubules affects periapical tissue remains unclear.

Interferon-gamma inducible protein 16 and type I interferon receptors expression in experimental apical periodontitis induced in wild type mice.

International Endodontic Journal, 2022
AIM The aim of this study was to evaluate the IFI16 and IFN-α/β receptors expression during the genesis and development of experimental apical periodontitis (AP) in mice teeth.

Yeasts in apical periodontitis

2019
Microbiological reports of apical periodontitis have revealed that yeasts can be isolated from approximately 5-20% of infected root canals. They occur either in pure cultures or together with bacteria. Almost all isolated yeasts belong to the genus Candida, and the predominant species is C. albicans. Pheno- and genotypic profiles of C.

Mesenchymal Chondrosarcoma Mimicking Apical Periodontitis

Journal of Endodontics, 2008
This report describes the case of a patient with mesenchymal chondrosarcoma in the region of tooth #18 that mimicked apical periodontitis. Forty-five days after endodontic treatment, gingival swelling and intense pain were observed. The endodontist suspected a furcation lesion, and the treatment option that the patient chose was extraction of the tooth.

Immunohistochemical study of apical periodontal cysts

Journal of Endodontics, 1998
Periapical lesions, as well as periodontal disease, seems to have cyclic patterns of evolution. Periods of burst may be intercalated with periods of quiescence. Because keratinocyte division must occur during cyst growth, it is presumed that epithelium status could indicate the biological activity of radicular cysts (RCs).

Melanoma with metastasis to an apical periodontal cyst

Oral Surgery, Oral Medicine, Oral Pathology, 1985
A rare case of multiple oral foci of metastatic melanoma in a 23-year-old man is presented. A unique aspect is the metastasis of a malignant neoplasm to the wall of an apical periodontal cyst.

Is adrenomedullin upregulation due to apical periodontitis independent of periodontal disease?

Odontology, 2022
To investigate the relationship between apical periodontitis [AP] severity and inflammatory markers [interleukin (IL)-12, tumor necrosis factor-alpha (TNF-α), and Mid-Regional Pro Adrenomedullin (MR-proADM)] in patients with AP. A total of 162 subjects were divided into three categories: AP group (n = 80), periodontitis (P) group (n = 42), healthy ...

Studies into the microbial spectrum of apical periodontitis

International Endodontic Journal, 1995
SummaryThis study examined the variety of obligate and facultative anaerobic bacterial species recovered from cases of acute apical periodontitis. A total of 19 root canal samples and 24 periapical granuloma samples were taken from patients suffering pain and discomfort.

Ameloblastoma Suggesting Large Apical Periodontitis

Journal of Endodontics, 2008
This case report describes the endodontic treatment of a large apical periodontitis with well-defined margins adjacent to teeth #22-24. After the initial endodontic treatment, continued expansion of the mandible cortical bone was observed, indicating a need to surgically enucleate the lesion and submit it for histopathologic examination.

The incidental discovery of apical periodontitis

Endodontic Topics, 2014
The incidental detection of asymptomatic apical periodontitis raises the question of whether or not this lesion should be treated. Arguments favoring treatment are that the inflammation may cause pain in the future, may enlarge, or may negatively affect the host's resistance.
