Inducing Apical Periodontitis in Mice

Journal of Visualized Experiments, 2019
The mechanisms involved in local induced inflammation can be studied using several available animal models. One of these is the induction of apical periodontitis (AP). Apical periodontitis is a common pathology of an inflammatory nature in the periodontal tissues surrounding the tooth root. In order to better understand the nature and mechanism of this

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.

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).

Inflammatory Myofibroblastic Tumor Mimicking Apical Periodontitis

Journal of Endodontics, 2015
Inflammatory myofibroblastic tumors (IMTs) are rare. IMTs of the head and neck occur in all age groups, from neonates to old age, with the highest incidence occurring in childhood and early adulthood. An IMT has been defined as a histologically distinctive lesion of uncertain behavior.

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.

Traumatic Bone Cyst Resembling Apical Periodontitis

Journal of Periodontology, 1997
Among the pseudocysts of the jaws, the traumatic bone cyst is known as an asymptomatic lesion often noted unintentionally during routine radiographic examinations. The lesion neither devitalizes the teeth within its borders, nor does it cause resorption of their roots. The well‐demarcated traumatic bone cyst often projects into the intraradicular septa

Changes in the periodontal membrane due to apical periodontitis

Journal of Endodontics, 1999
Teeth with an apical inflammatory lesion were studied by light microscopic morphometrical procedures to estimate the volumetric density of periodontal ligament tissues by point counting. Sixty-four root surfaces were investigated from coronal to apical. The observed tissue changes were similar in groups with and without bacteria, except for an elevated

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

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.
