Responses of oral epithelial cells to dental resin components

Journal of Biomaterials Science, Polymer Edition, 1996
The light-polymerized resins used in dentistry and their various constituents have been shown to produce significant levels of cytotoxicity, depending upon the material and the cell type exposed to it. These responses include altered cell growth and macromolecule synthesis.

Epithelial dendritic cells in pathological human oral tissues

Journal of Oral Pathology & Medicine, 1989
Epithelial dendritic cells (EDC) were examined in human oral tissues with non‐specific keratosis, lichen planus and squamous cell carcinoma. Acetone‐fixed frozen sections were stained using an indirect immunoperoxidase technique and monoclonal antibodies to the human CD1 thymocyte (OKT6) and HLA‐DR antigens.

MUC1 expression in the oral mucosal epithelial cells of the elderly

Archives of Oral Biology, 2011
MUC1 is primarily involved in the protection of epithelial surfaces. Decreases in oral mucosal defence can be a predisposing factor for the development of oral mucosal diseases in the elderly. The aim of this study was to compare MUC1 expression level in oral mucosal epithelial cells of the elderly with that of young adults.Thirty elderly (mean age, 71.

Cytoprotective effects of opioids on irradiated oral epithelial cells

Wound Repair and Regeneration, 2013
AbstractOral mucositis is a common side effect of chemotherapy and radiation therapy accompanied with acute inflammation and ulceration of the oral mucosa. Opioids can improve the wound healing of dermal and oral tissue when applied locally. The aim of this study was to investigate if morphine exhibits cytoprotective effects on oral epithelial cells ...

Characterization of epithelial cell activity in patients with oral cancer

British Journal of Oral and Maxillofacial Surgery, 1999
Accurate, predictive assessment of the clinical behaviour and progression of individual oral cancers and premalignant lesions requires reproducible and quantitative analyses of diseased tissue. In this paper we describe the use of in vitro double labelling (sequential tritiated thymidine and bromodeoxyuridine staining of proliferating epithelial cells)

Adrenomedullin expression in pathogen-challenged oral epithelial cells

Peptides, 2001
Adrenomedullin, a multifunctional peptide, is expressed by many surface epithelial cells and, previously, we have demonstrated that adrenomedullin has antimicrobial activity. The oral cavity contains an epithelium that is permanently colonized by microflora, yet infections in a host are rare. We exposed oral keratinocytes to whole, live cells from four

Fibrinolytic activity of human oral epithelial cells

European Journal of Oral Sciences, 1971
abstract – The fibrinolytic activity of human epithelial cells from the buccal mucosa of 5 females and 3 males was investigated using the fibrin slide technique. It was shown that cells from all layers of the squamous epithelium were fibrinolytically active. No sexual differences were recorded. The results are discussed with special reference to their

Ethanol Stimulation of HIV Infection of Oral Epithelial Cells

JAIDS Journal of Acquired Immune Deficiency Syndromes, 2004
Oral mucosal cells can be infected by exogenous HIV during receptive oral sex or breast-feeding. The risk of oral mucosal infection depends on the infection efficiency of the HIV strains present in the oral cavity, the viral titers, and the defense mechanisms in the oral cavity environment.

Non‐epithelial oral mucosal progenitor cell populations

Oral Diseases, 2007
This review considers the potential existence and role of stem or progenitor cell populations within the non‐epithelial tissues of the oral mucosa. Currently, there is little published evidence supporting this hypothesis; however, because of the similarities in structure and function of the oral mucosa and skin, findings within the dermis of the skin ...

Oral Innate Immunity and the Role of Oral Epithelial Cells

The oral mucosal epithelium is a complex structure that protects the underlying tissues from environmental exposure. Epithelial cells lining the mucosal surfaces of the oral cavity play an important role in innate immunity. They consist of stratified squamous epithelia that not only serve as a physical barrier but also contribute to innate immunity ...
