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).

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.

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.

Fungi in therapy-resistant apical periodontitis

International Endodontic Journal, 1997
The occurrence of yeasts in 967 microbiological endodontic samples taken from root canals in persistent endodontic infections was studied. The sampling was done by general practitioners in various parts of Finland from root canal infections which did not respond favourably to standard conservative therapy.

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.

[Endodontics and apical periodontitis].

Revue belge de medecine dentaire, 2005
The aim of this paper is to discuss the relation between root canal treatment and apical periodontitis (AP). AP is caused by micro organisms and is mainly a chronic inflammation. There is some evidence of an effect on the general health in immunocompromised patients. A higher incidence of AP on root filled teeth has been found. A number of preoperative

The role of hydrocortisone in the control of apical periodontitis

Oral Surgery, Oral Medicine, Oral Pathology, 1954
Abstract This investigation is a preliminary report on the effectiveness of hydrocortisone in certain clinical aspects of endodontic treatment. Reference is made to the saline suspension of hydrocortisone acetate (17-hydroxycorticosterone-21 acetate).

Bacteria in the apical root canal of teeth with primary apical periodontitis

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2009
Bacteria settled in the apical root canal are in a privileged position to inflict damage to the periradicular tissues. Therefore, the species identified in this region can be of special relevance for the pathogenesis of apical periodontitis. This study investigated the occurrence and levels of several bacterial taxa in the apical root canal of teeth ...
