The Periodontium Ch 14 Flashcards
Diastema
a space between two natural adjacent teeth
Desmosome
Cell junction; consists of a sense plate near the cell surface that relates to a similar structure on an adjacent cell, between which are thin layers of extracellular material.
Oral Epithelium
Tissue serving as a liner for the intraoral mucosal surfaces
Squamous epithelium
Composed of a layer of flat, scalelike cells; or may be stratified
Fibroblast
Fiber-producing cell of the connective tissue; a flattened, irregularly branches cell with a large oval nucleus that is responsible in part for the production and remodeling of the extracellular matrix
Hemidesmosome
Half of and desmosome that forms a site of attachment between junctions I epithelial cells and the tooth surface
Hyperkeritosis
Abnormal thickening of the keratin layer (stratum corneum) of the epithelium
Hyperplasia
Abnormal increase in volume of a tissue of organ by formation and growths of new normal cells
Hypertrophy
Increase in size of tissue or organ causes uh an increase in size of it’s constituent cells
Keratinization
Development of a horny layer of flattened epithelial cells containing keratin
Mastication
Act of chewing
Sharpey’s fibers
Penetrating connective tissue fiber by which the tooth is attached to the adjacent alveolar bone; the fiber bundles penetrate cementum on one side and alveolar bone on the other
Stippling
The putted, orange-peel appearance frequently seen on the surface of the attached gingiva
Suppuration
Formation of pus
Marginal
Confined to the free or marginal gingiva
