DAY 2 — CASE 19: The lesion on the cheek at the occlusal line level is most likely classified as which type?
Show answer and explanation
Correct answer: B. Reactive
- A. Infectious lesions (viral, bacterial, fungal) have different presentations and are not the most likely cause for a solid raised lesion at the occlusal line.
- B. A lesion on the cheek at the OCCLUSAL PLANE level is most likely a REACTIVE lesion — specifically due to chronic cheek biting (morsicatio buccarum), friction from the occlusal line, or minor trauma. Reactive lesions (fibroma, irritation fibroma, bite cheek keratosis/linea alba) represent the normal tissue response to chronic irritation.
- C. Developmental lesions are present from birth or early development — a 'recently noticed' lesion does not suggest developmental origin.
- D. Neoplastic lesions result from abnormal uncontrolled cell proliferation — unlikely for a lesion at the occlusal line level caused by chronic bite trauma.
