Quiz 1 Flashcards
clinical
how the lesion looks to the eye; the descriptive appearances. if the appearance is unique the diagnosis can be made without further tests
radiographic
the appearance on the radiograph determines the diagnosis i.e periapical pathology (PAP)
historical
what patient reports of the personal history, family history, past and present medical and dental histories, histories, history of drug ingestion and history of the presenting disease or lesion
laboratory tests
including blood chemistries and urinalysis can yield a diagnosis
microscopic diagnosis
a lab test of sorts but is separate because evaluation of the specimen taken from the lesion gives very specific information. biopsy is often the main component of a definitive diagnosis
surgical diagnosis
surgical intervention shows if there is a traumatic bone cyst or a lingual bone concavity. diagnostic category of surgical diagnosis tells conclusively when the lesion is opened and an empty void is found that the diagnosis is a traumatic or a simple bone cyst. it give conclusive evidence
Therapeutic diagnosis
Nutritional deficiencies are diagnosed by therapeutic means e.g. angular chelitis may be associated with a B complex deficiency and ANUG response to hydrogen peroxide rinses
Differential diagnosis
The point in the diagnoses when the practitioner decides which test or procedure is required to rule out the conditions are originally and establish a definitive or final diagnosis
Clinical appearance of Fordyce’s granules
Appear as yellow lobules in clusters and are usually distributed over the buckle mucosa or Vermilion border of that involved lips
Clinical appearance of Torus Palatinus
May have various sizes and shapes, maybe lobulated and is covered by normal soft tissue
Clinical appearance of Mandibular tori
Are often lobulated or nodular and can appear fused together
Melanin pigmentation
The oral mucosa or gingival is commonly seen in dark skinned individuals
Retrocuspid papilla
A sessile nodule on the gingival margin of the lingual aspect of the mandibular canine’s
Lingual varicosities
Red to purple enlarge vessels or clusters of the vessels usually on the ventral and lateral surfaces of the tongue
Linea alba
A white line that extends anterioposteriorly and on the buccal mucosa along the occlusal plane
Leukoedemia
Refers to generalized opalescence on the buckle mucosa. Seen as a gray – white film on the buckle mucosa that when stretched becomes less prominent
Lingual thyroid nodule
Occurs when the thyroid tissue is either does not descend or remnants become trapped in the tissue the make up the tongue
Median rhomboid glossitis
Seen clinically as a flat or slightly raised oval or rectangle or erythrmatous area in the midline of the dorsal surface of the tongue. Maybe associated with a candida infection
Geographic tongue
Seen as a diffuse area devoid of filiform papilla on the dorsal and lateral borders of the tongue. Seen as erythrmatous patches that are surrounded by a white or yellow perimeter
Ectopic geographic tongue
Use describe the condition when it is found on the mucosal surfaces other than the tongue
Fissured tongue
Seen clinically when the dorsal surface of the tongue appears to have deep fissures or grooves that can become irritated if food collects in them
Hairy tongue
A condition in which the patient has an increased accumulation of keratin on the filiform papilla. The filiform papilla become elongated and can appear white, yellow, brown or black. The color of black hairy tongue is due to chromogenic bacteria, White from tobacco chemicals, alcohol and food. Anabiotic’s, corticosteroids, radiation, or Candida albicans can yield hairy tongue
Injury
Tissue damage caused by trauma or an alteration in the environment
Repair
The restoration of damaged or diseased tissue
Inflammatory
A nonspecific response to injury and occurs in the same manner, regardless of the nature of the injury. Inflammation of a specific tissue is denoted with the suffix -itis. Can be acute or chronic
Immunity
The ability of an organism to resist or not be susceptible to injury or infection
Five classic signs of localized inflammation are:
Redness, heat, swelling, pain, loss of normal tissue function
Three systemic signs of inflammation are:
increase in body temperature (fever), increase in number of white blood cells (leukocytosis), enlargement of the lymph nodes (lymphadenopathy)
List and describe the microscopic events of the inflammatory process
A. Injury to tissue.
B. Constriction of the microcirculation.
C. Dilation of the microcirculation.
D. Increase in permeability of the microcirculation.
E. Exudate leaves the microcirculation, causes swelling.
F. Increased blood viscosity.
G. Decreased blood flow through the microcirculation.
H. Migration and pavementing of white blood cells
Neutrophils/polymorphonuclear leukocytes (PMNs)
The first cells to immigrate to the site of injury and are the primary cells involved in acute inflammation. These cells phagocytize substances such as pathogenic microorganisms and tissue debris, injured tissue produces chemotactic factors that cause the PMNs to use the lysomal enzymes in their vacuoles to destroy the substances the PMNs have engulfed
Monocytes
The second cell to enter injured tissue where they become macrophages. Macrophages respond to chemotactic factors. The macrophage is capable of phagocytosis, is mobile, and has lysosomal enzymes in its cytoplasm that assist in the destruction of foreign substances. Besides phagocytosis, the macrophage acts as a helper during the immune response
Lymphocytes
Involved in chronic inflammation and immune response
Plasma cells
Involved in chronic inflammation and the immune response
Eosinophils and mast cells
Participate in both inflammatory and immune responses
Acute inflammation
If the injury is minimal and brief at sources removed from the tissue
Chronic inflammation
Chronic injury occurs of injury to the tissue continues. Sometimes acute and chronic inflammatory responses are superimposed on each other
What are the main white blood cells in acute inflammation
Mostly PMNs
White blood cells in chronic inflammation
Macro phages, lymphocytes and plasma cells are common
