A patient with a history of scarlet fever presents for dental examination. Which of the following is NOT an expected finding associated with scarlet fever?
Show answer and explanation
Correct answer: C. Spontaneous gingival bleeding
Scarlet fever, caused by Group A Streptococcus (S. pyogenes) exotoxin-producing strains, presents with a characteristic syndrome: high fever, pharyngitis, palatine petechiae, 'strawberry tongue' (initially white-coated with swollen red papillae, then bright red), and a diffuse erythematous sandpaper-like skin rash beginning on the trunk. The oral mucosa appears bright red ('scarlet'), hence the disease name. Spontaneous gingival bleeding is NOT a feature — gingival bleeding is associated with vitamin C deficiency (scurvy), coagulation disorders, or severe periodontitis. Petechiae on the soft palate are present, but overt gingival hemorrhage does not occur.
