Chapter 2 -Inflammation & Repair Flashcards
Idiopathic tooth resorption
Resorption involving the crown of an impacted tooth or the roots of the teeth and the cause can’t be identified
Internal tooth resorption
Starts from the root canal and destroys the surrounding tooth structure
Condensing osteitis
Focal sckerosing osteomyelitis; a change in bone near apices of the teeth that may be a reaction to low grade infection.
Alveolar osteitis
Known as dry socket; postoperative complication after extraction due to loss of blood clot before healing takes place.
Keloid
Excessive scarring that mainly occurs in the skin in some cases with healing.
Leukocytosis
An increase in the number of white blood cells circulating the blood. 
Leukopenia
A decrease in the number of white blood cells circulating the blood.
Local
A disease process that is confined to a limited location in the body that is not general or systemic. 
Lymphadenopathy
The abnormal enlargement of a lymph node or nodes. 
Macrophage
The second type of white blood cell to arrive at a site of injury that was originally a monocyte; it participates in phagocytosis during inflammation and continues to be active in the immune response.
Atrophy
Abnormal decrease in the number of cells in an organ or tissue
Biochemical mediators
Chemicals in the body that activate responses
Central
In the context of oral lesions central indicates that the lesion is within bone
Chemotaxis
The movement of white blood cells as directed by biochemical mediators to an area of injury
Chronic
An Injury or course of inflammation that is a long duration
C-reactive protein
A nonspecific protein produced in the liver that becomes elevated during episodes of acute inflammation or infection
Exudate
A body fluid with a high protein content that leaves the microcirculation during inflammatory response that consists of serum that contains white blood cells, fibrin, and other protein molecules
Fever
An elevation of body temperature to greater than teh usual level of 37 degrees celsius (98.6 degrees fahrenheit)
Fibroblasts
The cells that form fibers as well as intercellular substance
Fibroplasia
The formation of fibrous tissue as usually occurs in healing
Fistula
An abnormal passage that leads from an abcess to the body surface
Granulation tissue
The initial connective tissue formed in healing
Repair
The restoraiton or damaged or diseased tissue by celluarl change and growth
Serous exudate
An exudate that has watery consitency. The consitency resembels that of serum
Systemic
Pertainiung to or affectin gth body as whole, as well as a deasesd process pertaining to or affecting the body as a whole
Transudate
The extravascular fluid component of blood taht passess thorught the endothelila. Cell walls of the microcirculation.
White blood cells
The cells within the blodd and surrouding tissue, also called leukocytes, taht are involved in the inflamatory and immune resosne
Traumatic injury
A disese process that results form injury taht causes tissue damage.
Margination
A process during inflammation in which white blood cells tend to move to the periphery of the blood vessel at the site of injury.
Microcirculation
The small blood vessels including arterioles, capillaries, and venules of the vascular system.
Myofibroblasts
Fibroblasts that have some of the characteristics of smooth muscle cells, such as the ability to contract.
Necrosis
The pathologic death of one or more cells, or a part of tissue, or an organ that results from irreversible damage to cells.
Neutrophil
The first white blood cell to arrive at a site if injury; the primary cell involved in acute inflammation; also called a polymorphonuclear leukocyte.
Opacification
The process of becoming opaque.
Abscess
A collection of purulent exudate that has
accumulated in a contained space formed by the surrounding
tissue.
Actinic
Relating to or exhibiting chemical changes
produced by radiant energy, especially the visible and
ultraviolet parts of the spectrum; relating to exposure to the
ultraviolet rays of sunlight.
Acute
An injury or course of inflammation that is of short
duration.
Angiogenesis
The formation and differentiation
of blood vessels.
Granuloma
a tumorlike mass of inflammatory tissue consisting of a central collection of macrophages often including multinucleated giant cells surrounded by lymphocytes
Hyperemia
an excess of blood within blood vessels in a part of the body
Hyperplasia
Enlargement of a tissue or organ resulting from an increase in the number of cells; the result of increased cell division
hypertrophy
Enlargement of a tissue or organ resulting from an increase in the size of its individual cells but not in the number of cells
Inflammation
A non-specific response to injury that involves the micro circulation and its blood cells
Injury
an alteration in the environment or trauma that causes tissue damage
Opsonization
The enhancement of phagocytosis by a process in which a pathogen is marked, with opsonins, for destruction by phsgocytes.
Osteoblast
The cell that forms bone
Pavementing
The adherence of white blood cells to blood vessel walls during inflammation.
Peripheral
In the context of oral lesions, peripheral indicates that the lesion is within the gingival tissue or alveolar mucosa
Phagocytosis
The ingestion and digestion of particulate material by cells.
Purulent Exudate
An exudate containing or forming pus
Transudate
Extravascular fluid component of blood thatpasses through the endothelial cell walls of the microcirculation.
White blood cells
Known as leukocytes; are cells within the blood and surrounding tissue involved in inflammtory and immune responses
Traumatic injury
Disease process that results from injury that causes tissue damage
Waldeyers ring
Ring of lymphatic tissue formed by two palatine tonsils the pharyngeal tonsil the lingual tonsil and intervening lymphoid tissue.
Cytolysis
Destruction of cell
Demastication
Tooth wear is increased by chewing abrasive substances
Edema
Excess level of exudate that causes tissue swelling
Emigration
Passage of WBC’s through cell walls of small blood vessels and into injured area
Epithelialization
Process of new surface layer of epithelium
Erythema
Redness of skin or mucosa
