Which vitamin is affected when gums are erythematous, tongue shows papillary atrophy?
Show answer and explanation
Correct answer: B. Vitamin B (complex)
ERYTHEMATOUS GUMS + PAPILLARY ATROPHY OF TONGUE (smooth, glossy tongue) suggests VITAMIN B COMPLEX DEFICIENCY. Specifically: B2 (riboflavin) causes magenta/glossy tongue; B3 (niacin) causes pellagra with glossitis; B12 causes atrophic glossitis; folate causes similar changes. Collectively, B vitamin deficiencies cause GLOSSITIS (tongue changes) and oral mucosal changes. Vitamin C causes bleeding gums but not typically papillary atrophy. B is correct.
