1-studies the causes of diseases, mechanisms which produce them, sites where they occur & the resulting morphologic & functional alterations
2-speciality of dentistry & path which deals w/ nature, identification & managements of diseases affecting the oral maxillofacial regions
3-physical changes in the mouth caused by diseases—generic terms used to describe
4-macule & patch
5-fluid fuilled & solid
6-vesicle, bulla, & pustule
7-plaque, pseudom, papule, nodule, & tumor
8-erosion & ulcer
macule: flat change in color <1 cm
patch: flat change in color >1 cm
plaque: solid, raised, flat topped lesion

fordyce granules
sebaceous glands occurring in the oral cavity
1-fordyce granules
2-Torus palatinus
3-Erythema migrans
4-varicosities
1-affects 70% of pop
most common in buccal mucosa & upper lips
diagnosis via clinical exam
no treatment is required
2-affects 20-25% of pop
2: 1 women to men
diagnosis on clinical exam alone
no treatment needed unless interfering w/ function
3-lesions on tongue, appear heal & develop elsewhere but can be places other than tongue
- diagnosis on clinical exam alone
- no treatment needed
4-dilated vessel filled w/ blood
rare in children, common in adults
-mostly seen in lower limbs
seen in tongue of 2/3 of older adults
-diagnosis on clinical exam
-no treatment is required
fordyce granules
fordyce granules
Torus palatinus
commonly on midline
torus mandibularis
Erythema migrans
Erythema migrans: Georgraphic tongue
Erythema migrans
sublingual varicosities
sublingual varicosities
1-Fissured tongue
2-leukoedema
3-Linea alba
1-may be heredity
numerous grooves on dorsal surface of tongue
-diagnosis on clinical exam
-no treatment is required
2-in 70-90% of black adults and 50% of black kids
- severe in smokers
- milky, wrinkled appearance of mucosa
- diagnosis on clinical exam
- dissapears upon stretching of mucosa
- no treatment needed
3-associated w/ friction from facial surfaces of teeth
- diagnosis on clinical exam alone
- hyperkeratosis
- no treatment needed
Fissured tongue
leukoedema
leukoedema
disappears upon stretching of mucosa
leukoedema
Linea alba
1-morsicatio buccarum
2-Lymphoid aggregate
1-2:1 women to men
diagnosis on clinical
chronic biting
hyperkeratosis
no treatment required
2-lingual tonsil: lymphoid aggregate located on lateral border of tongue
- also seen in soft palate, tonsillar pillars & floor of mouth
- no treatment is required
Morsicatio buccarum
Morsicatio linguarum
Morsicatio labiorum
hyperkeratosis
Morsicatio buccarum &&& linea alba
lingual tonsil
lymphoid aggregate
abrasion wear vs attrition wear
- below mandibular canal= unlikely odontogenic (if above= odontogenic)
- w/in mandibular canal= vascular or neural
- epicenter of lesion w/in sinus (not odontogenic)
generalized lesion
localized
