NEET MDS 2026: MERITERS PREDICTIONS | Oral Medicine - 15 MOST LIKELY Question Topics
The Philosophy
"While Oral Pathology looks at the microscope, Oral Medicine looks at the patient. Focus on clinical signs, diagnostic criteria, and medical management strategies."
A targeted breakdown of the highest priority topics based on recent question patterns and examiner logic.
1. Trigeminal Neuralgia (Tic Douloureux)
High PriorityCore Focus
- Clinical presentation: Unilateral, sharp, shooting, electric-shock like pain
- Trigger zones (washing face, shaving, brushing)
- Medical Management: Carbamazepine (Drug of choice)
NEET MDS Logic
The quintessential oral medicine pain question. Examiners love the specific adjectives for the pain and the exact first-line pharmacological treatment.
Framing: "A 55-year-old female complains of sudden, severe, electric-shock like pain on the right side of her face triggered by washing her face. The drug of choice is?"
Past Question Patterns
