In an attempt to verify the nature of bone resorption processes on the bone surrounding radicular cysts, fragments of cysts with the adjacent bone tissue were studied by morphological, cytochemical and ultrastructural methods. Cyst fluid was analysed for its content of cytokines with osteolytic
In consideration of the close relationship between radicular cysts and alveolar bone, it is important to evaluate the potential involvement of the neighbouring bone tissue in such lesions. In the present study, using cytochemical, immunocytochemical and morphological analyses, presumptive osteoclast
Of a total of 1,420 odontogenic cysts, 52 (3.3%) were diagnosed as odontogenic keratocysts. Clinical and histological findings in these 52 cysts are reported. Frozen sections of 26 of the keratocysts were incubated to show the following enzyme activities: NADH2- and NADPH2-diaphorase,
A histoenzymological study was carried out on 41 tissue specimens removed at biopsy and for surgical operations of the following lesions: benign hyperkeratosis, lichen planus, severe epithelial dysplasia, carcinoma in situ, epidermoid carcinoma, radicular cyst, odontogenic keratocyst and
An histoenzymological study (including oxidative enzymes, diaphorases, acid and alkaline phosphatases and naphtolesterases) of 41 biopsy and operation specimens revealed interesting factors in the diagnosis of some lesions of the buccal mucosa, and also of cysts and ameloblastomas of the jaw. When
The aim of this study was to examine the level and basic characteristics of cell‑derived microparticles (MPs) in the cyst fluids of odontogenic keratocysts (OKCs). For this purpose, MPs from the cyst fluids (CFMPs) of OKCs were purified by a classic differential centrifugation method and
BACKGROUND
Hypophosphatasia is a rare inherited disease derived from mutations in tissue non-specific alkaline phosphatase genes, with typical oral symptoms including short root anomaly and dysplasia of dentin or cementum.
METHODS
Two young female patients presented with short root anomaly with a
A histoenzymological study was carried out on 40 tissues specimens removed at biopsy and for surgical operations of the following lesions: 5 normal oral mucosa, 5 periapical granulomas, and 30 periapical inflammatory cysts. The purpose of this study was to study some possibly significant variations
Humoral immune responses are implicated in the pathogenesis of human dental periapical lesions. To elucidate whether IgA-associated immune systems play a role in the lesions, the in situ hybridization technique was used to detect J chain mRNA expression, which is correlated with the secretion of
RANKL (receptor activator of nuclear factor kappaB ligand) promotes osteoclast differentiation, stimulates osteoclast activity, and prolongs osteoclast survival and adherence to bone. Abnormalities of the RANKL/RANK/osteoprotegerin system have been implicated in a range of diseases, including
