Diffuse erythema (pinpoint petechiae) and white patches in smoker's palate occur due to________________?
Correct answer: B. Keratinization with partially occluded minor salivary glands
- A. Complete obstruction to minor salivary gland orifices
- B. Keratinization with partially occluded minor salivary glands
- C. Diffuse parakeratinization of the palate
- D. Excessive orthokeratinization of the palate
Explanation
Nicotine stomatitis causes palatal keratinization and inflammation around partially blocked minor salivary gland ducts, producing white thickening with pinpoint red duct openings. Complete obstruction would not explain the characteristic diffuse pinpoint petechiae.
