Oral Path *** Flashcards
autosomal dominant condition that affects dentin in both deciduous & permanent
Dentin Dysplasia
Type I dentin dysplasia
(radicular)
more common
rootless teeth
teeth are extremely mobile leading to premature exfoliation
completely obliterated pulp (not present pulp)
Type II (coronal)
Deciduous: opalescent color, completely obliterated pulp
Permanent: normal color, enlarged pulp chamber (thistle tube)
new growth excessive & uncontrolled growth of abdominal tissues
Neoplasm
swelling any swelling or abnormal enlargement in the body
Tumor
study of tumors or neoplasm
Oncology
composed of cells or tissues originating from 3 germ layers
Teratoma
abnormal cells normally found in the affected organ
Hamartoma
normal cells in an unusual location
ex. Fordyce spots
Choristoma
spread of tumor to adjacent tissues
Invasion/ Infiltration
spread of tumor to distant tissues
Metastasis
change from normal to abnormal
Dysplasia
change from one cell type to another
Metaplasia
loss of differentiation
Anaplasia
Hallmarks of Anaplasia
Pleomorphism
Hyperchromatism
Abnormal mitosis
Loss of polarity
premalignant lesion
white patch or plaque of oral mucosa that cannot be rubbed off & cannot be chracterized as any other disease
Leukoplakia
premalignant lesion, Red patch or plaque of oral mucosa that cannot be rubbed off
Erythroplakia
malignancy involves full thickness of epithelium
Carcinoma in situ
malignancy involves full thickness of the epithelium as well as penetrates the basement membrane
Invasive carcinoma
BENIGN (oma)
well differentiated slow growth well circumscribed localized movable
MALIGNANT (sarcoma , carcinoma)
BIG FEUD
less differentiated , no differentiation rapid growth poorly circumscribed metastasis immovable
Malignant (BIGFEUD)
Bleeding Induration Growth rate Fixated Erythroplakia Duration
