BACKGROUND Oral lichen planus (OLP) is a chronic inflammatory disease with different clinical presentations that can be classified as reticular, atrophic or erosive. Although OLP is a relatively common disorder, the reports comprising large numbers of OLP patients with specific character are lacking in the literature. The purpose of this paper was to(More)
OBJECTIVE To describe clinical and histological features of oral granular cell tumor (OGCT)and discuss their proliferative activity. METHODS Clinical and microscopic features were assessed in 14 cases of OGCT collected from the department of oral pathology, college of stomatology of Wuhan University between 1970 and 2003. Immunohistochemical analysis was(More)
OBJECTIVE To investigate the expression and the localization of Cathepsin K and IL-6 mRNA in root-resorbing tissue and to elucidate the molecular changes and mechanism of root resorption induced by tooth movement. METHODS Rats were subject to experimental tooth movement to induce root resorption. In situ hybridization was performed to identify the cells(More)
OBJECTIVE To investigate clinicopathological and immunohistochemical features of 31 cases of oral teratoid cyst. METHODS Thirty-one cases of oral teratoid cyst according with Meyer's diagnosis criteria were retrospectively studied and their histochemistry and immunohistochemistry were performed from the files of Department of Pathology, School of(More)
OBJECTIVE To evaluate the value of the invasive front grading (IFG), the proliferative activity of cells at the invasive tumor front (ITF) of squamous cell carcinoma (SCC) of tongue. METHODS All the tumors were graded using IFG grading. The expression of PCNA, Ki67 and staining and measurement of AgNOR number were evaluated at the ITF and the other parts(More)
PURPOSE To evaluate the biological effect of retinoic acid on cultured human periodontal ligament cells. METHODS Human periodontal ligament cells were cultured and challenged by retinoic acid with different concentrations. The cell morphology was observed under phase-contrast microscope; the cell proliferation activity was examined using MTT; the alkaline(More)
OBJECTIVE To observe the ultrastructural features of taste pores and taste pits of human taste buds. METHODS Three samplers obtained randomly from adults were divided into two perts, and transmission electron microscopy and scanning electron microscopy were used to observe the fine structure of taste buds in human circumvallate papillae. RESULTS The(More)
OBJECTIVES To investigate the carious dissolution mechanism of enamel apatite nano-crystals at lattice fringe level and the possible correlation between the carious dissolution and the appearance of central dark line (CDL) in enamel crystals. METHODS The body of the lesion in incipient enamel caries was observed by high resolution transmission electron(More)
OBJECTIVE To investigate the different characteristics of periodontal ligament cells and gingival fibroblasts in synthesizing Collagen I and III. METHODS Periodontal ligament cells and gingival fibroblasts were cultured from the same patient and detected for expression of Collagen I and III by immunocytochemical methods. RESULTS The immunocytochemical(More)
