[The functional morphology of the epithelial barrier of the oral mucosa].
Modern notions on the morphology and function of the epithelial barrier of the buccal mucosa are discussed. The basis of this barrier is the epithelial layer, partially covered with horny layer, of a regular thickness and permeability, constantly regenerating, and casting off the injured superficial layers. Nonspecific antibacterial humoral factors (produced by the epithelium and salivary glands) play an important role in the barrier mechanisms, as well as nonspecific cellular mechanisms of defense, due to the presence of intraepithelial granulocytes and monocytes, specific immune humoral and cellular mechanisms including the system of antigen-presenting dendrite cells and lymphocytes, and flow of the saliva containing nonspecific and specific antibacterial factors. The barrier function of the epithelium is provided for by constant interactions between various specific and nonspecific cellular and humoral defense mechanisms.
