Path Flashcards
Central giant cell granulomas
- benign neoplasms that usually occur in the mandible, twice as often in women
- haracterized by a large radiolucent multilocular lesion that expands the cortical plate and can resorb roots and move teeth
Ameloblastomas
radiolucent multilocular lesions, commonly mistaken for central giant cell granulomas
* aggressive form exhibits rapid growth, likely to absorb roots and perforate cortical plate, painful and can cause paresthsia
Dentigerous cysts
aka follicular cysts
- only occur along the crown area of a partially erupted tooth
- lining ORGINATES from the epithelial cells of the reduced enamel epithlium of the tooth
Nasopalatine cyst
heart shaped radioluncy between MX anterior teeth
- commonly have nonsymptomatic palatal swelling
- typically no periapical in fection bc the MX teeth are vital
Dentin Dysplasia
hereditary disease
- disturbance of normal dentin
- pulpal chamber obliteration
- alteration or absence of root formation
- premature tooth exfoliation
Dentinogenesis VS dentin dysplasia
Dentinogenesis imperfecta is a form of dentin dysplasia, which causes discoloration or translucency in the affected teeth
what is Amelogenesis imperfecta? what is it missing? what color?
hereditary development disease
- thin/weak abnormally formed enamel. avascular and highly calcified and does NOT contain proteins ameloblastin, enamelin, tuftelin and amelogenin
- yellow or brown
- clinically have rampent carries and attrition
osteogenesis gives what color?
blue hue
radiographically describe amelogenesis VS dentinogenesis
Amelogensis
- enamel appears absent or VERY thin on cusp tips and interproximal surfaces
- tooth is square, devoid of normal mesial and distal contours
Dentinogenesis
- bulbous crowns with constricted short roots
- initially pulp chambers may be abnormally wide and resemble shell teeth, but they progressively obliterate
