ORAL PATHOLOGY CORE EXAM MANUAL QUESTIONS
AND SOLUTIONS GRADED A+
✔✔Erosion of soft tissue - ✔✔a shallow defect in the mucosa caused by mechanical
trauma, such as chewing. Margins may be ragged and red and quite painful.
✔✔Abscess - ✔✔collection of pus in a specific area; commonly found at the apex of a
tooth and can be caused by bacteria in a badly decayed tooth or by bacteria resulting
from a severe periodontal infection
✔✔Cyst - ✔✔fluid or semisolid fluid filled sac; material is not always infections. Can
form around the crown of an encrypted tooth
✔✔Lesions extending BELOW mucosal surface - ✔✔-Ulcer
-Erosion of soft tissue
-Abscess
-Cyst
✔✔Lesions extending ABOVE the mucosal surface - ✔✔-Blisters (vesicles)
-Pustule
-Hematoma
-Plaque
-Papules
✔✔Blisters - ✔✔also known as vesicles, are filled with a watery fluid
✔✔Pustule - ✔✔looks like blister but contains PUS
✔✔Hematoma - ✔✔Similar to blister but contains BLOOD; sometimes caused by
anesthetic injection
✔✔Vesicle - ✔✔diameter is .5 or less
✔✔Bulla - ✔✔diameter is greater than 0.5
✔✔Plaque - ✔✔any patch or flat area; used to describe the silvery scales of psoriasis
✔✔Dentigerous cyst - ✔✔A cyst that forms around the crown of an unerupted or
developing tooth.
✔✔Signs of inflammation - ✔✔redness, heat, swelling, pain
✔✔Fistula - ✔✔abnormal passageway between abscess and surface of mucosa
, ✔✔Papules - ✔✔elevated areas of skin that vary in pigmentation and texture
✔✔Skin plaques include - ✔✔-eczema
-psoriasis
-dermatitis
✔✔What lesions are even with the mucosal surface - ✔✔-Ecchymosis
-Macules
-Petechiae
✔✔Eccyhmosis - ✔✔bruising (blood in an extravascular space); measure over 1 cm in
size.
✔✔Nodules - ✔✔may appear below the surface or may be slightly elevated, are small,
round, solid lesions. When palpated, a feels like a pea
✔✔Macules - ✔✔a flat, distinct, discolored area of skin.
✔✔Petechiae - ✔✔a small red or purple spot caused by bleeding into the skin; 1-2 mm
in size
✔✔Purpura - ✔✔larger than the petechiae, but less than 1 cm in size.
✔✔Petechiae, purpura, or ecchymoses lesions are mostly due to - ✔✔trauma.
✔✔If the nodule can be rolled - ✔✔sign that the lesion is more likely benign rather than
malignant
✔✔Malignancies - ✔✔are indurated; they are invasive and grab surrounding tissue.
✔✔Granuloma - ✔✔type of nodule that contains granulation tissue (tissue that grows
from the base of a wound and can fill wounds of almost any size)
✔✔Tumors - ✔✔also known as neoplasms; any mass of tissue that grows beyond the
normal size and serves no useful purpose (maybe benign or malignant)
✔✔Leukoplakia - ✔✔general term that means "white patch."Commonly linked to chronic
irritation or trauma; Very often precedes the development of a malignant tumor
✔✔To be classified as leukoplakia - ✔✔the lesion should be firmly attached to the
underlying tissue, and rubbing or scraping with an instrument should not remove it.
✔✔Leukoplakia may result from - ✔✔the use of smokeless tobacco, poorly fitting
dentures, or cheek biting
