A patient has erythematous gingiva, tongue allodynia (pain to touch), and papillary atrophy of the tongue. Which vitamin deficiency is most likely?
Show answer and explanation
Correct answer: A. Vitamin B (B complex)
- A. B-vitamin deficiencies (B2/riboflavin, B3/niacin, B12, folate) cause atrophic glossitis with papillary atrophy, burning/painful tongue, and erythematous mucositis. This is the classic oral presentation.
- B. Vitamin D deficiency affects bone mineralization and is not directly associated with this oral presentation.
- C. Vitamin C deficiency (scurvy) causes hemorrhagic, swollen, friable gingiva — not specifically tongue allodynia and papillary atrophy.
- D. Vitamin E deficiency primarily causes neuromuscular problems; not specifically associated with this oral presentation.
