- Monostotic fibrous dysplasia
Florid cemento-osseous dysplasia
What is one difference between the diagnosis of periapical and florid cemento-osseous dysplasia?
- Florid usually affects more than one quad of max and mand, including post.
- Periapical affects black females; florid affects all ethnicities

Which statement about epithelial dysplasia is true?
- Is is considered a malignant condition
- Unlike squamous cell carcinoma, cellular changes in epithelial dysplasia may revery to normal is teh stimulus, such as tobacco, is removed
- It presents clinically as an erythematous lesion and not a white lesion
