5 malignant "-oma's"

Lesions are described based upon:

2. tissue consistency
5. surface texture
6. radiographic appearance
8 Diagnostic Categories:
Clinical Diagnosis could consist of:
appearance of lesion, color, shape, location or history
Occurs in black women in 60's, asymptomatic, teeth are vital and usually the anteriors are affected
Periapical Cemental Dysplasia
Elevated serum alkaline phosphatase level
B-compled deficiency, most commonly a fungal. responds to antifungal cream
Acute Necrotizing Ulcerative Gingivitis
Clusters of ectopic sebaceous glands. Occurs on lips and buccal mucosa.
Pigment that gives color to skin, eyes, hair, mucosa, and gingiva
Sessile nodule on gingival margin of the lingual aspect of mandibular canines.
Prominent veins located on ventral/lateral surfaces of tongue
"white line" on buccal mucosa along occlusal plane, usually bilateral. Prominent with bruxism and clenching.
Generalized opalescence of buccal mucosa, most commonly in African Americans. Disappears when mucosa is stretched.
Throid tissue that has become entrapped in the tissues of the tonue. More common in females. Located as a mass in the midline of dorsal of tongue in the area of the foramen caecum. Benign.
Lingual Thyroid Nodule
Deep groves in dorsal of tongue. Possibly associated with vitamin deficiency or chronic trauma. unknown cause
Flat or slightly raised oval or rectangular erythematous area in the midline of dorsal surface of tongue. Devoid of Filiform papillae, no specific treatment
Median Rhomboid Glossitis
Diffuse areas of desquamation of filiform papillae. Erythematous patches with well defined boreder of white or yellow. "Benign Migratory Glossitis"
Filiform papillae become enlongated and appear white, yellow, black or brown
Short duration, arises quickly
Movement of WBS's to area of injury
Long duration, persists for a long time
Passage of WBC's through endothelial wall of small blood vessels
Inflammaroty fluid (pus)
Elevation of body temperature higher than 98.6 degrees F
Excess of blood in a part of the body
Abnormal multiplication or increase in the NUMBER of normal cells.
Enlargement of tissue or oran due to an increase in the SIZE of the cell
Affects body as a whole
Temporary increase in the number of WBC's circulating in the blood
confined or limited to a part
Enlargement or swelling of a lymph node
Occurs in the early stage of inflammation; WBC's occupy the periphery of a blood vessel and adhere to endothelial cells lining the blood vessel
Pathologic death of cells or portions of tissue
The adherence of WBC's to the endothelial cells lining an injured blood vessel
Located away from the center
ingestion and digestion of a foreign substance by cells
Containing or forming pus
restoration of damaged or diseased tissue
having a fluid or water consistency (relates to serum)
Localized swelling of tissue due to edema, accompanied by severe itching
What eliminates injurious agents, contains injuries and heals defects?
Nonspecific response to injury and occurs in the same manner regardless of nature of injury
suffix meaning inflammation
Cardinal Signs of Inflammation
5. loss of tissue function
A formation of a natural drainage passage boring through tissue allowing drainage of exudates
6 Types of White Blood Cells
4. plasma cells
6. mast cells
1st cell to emigrat and first cell involved in acute inflammation
2nd cell to emigrate
Involved in chronic inflammation and immune response
lymphocyte and plasma cell
Both inflammation and immune respone
Eosinophil and mast cell
Macrophages, lymphcytes and plasma cells become predominantes during what?
60 - 70 % of WBC, phagocytosis then dies
Become Macrophages, 3 - 8 % of WBC, lysosomal enzymes to aide in destruction of foreign substances
Start or enhance the inflammatory response
3 Systems of Chemical Mediators
1. Kinin System
2. Complement System
3. Clotting System
Mediates inflammation by causing increase dilation of blood vessels at eh site permeability of blood vessels by widenign gaps between endothelial cells. Early phase of inflammation
Production of sequential cascade of plasma proteins that are present in the blood in an activated form. Rease of Histaine (mast cells)
Clots blood and helps with repair, platelets
Body temperature regulated by:
Hypothalamic Thermoregularoty center
the body's final defense mechanism in its attempt to restore injured tissue to its original state
Healing of an injury in which there is little loss of tissue, surgical incision, edges joined by sutures, less scar tissue
Healing by Primary intention
Injury whereby there is a loss of tissue and the edges of the injury cannot be joined during healing
Healing by secondary intention
Infection occurs at the site of surgical incision that is healing by primary and secondary intention may ensue
Wearing away of tooth structure during mastication
Grinding and clenching teeth together for nonfunctional purposes
Signs of bruxism
1. wear facets
2. abnormal rate of attrition
3. hypertrophy of masticatory muscles
4. increase muslce tone
5. muscle fatigue
6. cheek biting
7. TMJ pain
Pathological wearing away of tooth structure that results from a repetitive mechanical habit, pulp exposure usually not present
Loss of tooth structure resulting from chemical action (usually on lingual/facial but can be occlusal/interproximal)
Eating disorder of food binges followed by self-induced vomiting
Characterized by distored perception of body image along with depression, intense fear of gaining weight and self-imposed starvation
Occurs when patient places aspirin beside a tooth with a toothache
Causes whitening of area/ulcer if not removed quickly
Usually children who have bitten/chewed a live electric cord or inserted something into an electric socket
Lesions located at midline of hard palate varifying from ulcers to keratotic to exophytic reactive lesions. Caused by smoking crack
Chronic rubbing or friction against mucosa resulting in a thickening of the keratiin on the surface
Benign lesion on hard palate associated with smoking
Lesion that forms whena salivary gland duct is severed and teh mucous secretion spills into the adjacent CT
Occurs as a result of an obstruction of a salivary gland duct or infection
Common occuring intraoral lesion characterized by proliferation of CT containing blood vessels/inflammatory cells, surgical excision

Most common cyst in oral region
Radicular (PA) Cyst
Appears as slight raggedness or blunting of the apex and can proceed to severe loss of tooth root structure
External Root resorption
Change in bone near apex thought to be reaction to low grade infection. Usually associated with carious tooth or large restoration. Asymptomatic in young adults. No treatment
