• Nutritional deficiency of Vitamin C (Ascorbic acid)
  • Vitamin C is typically found in fruits and vegetables.
  • Vitamin C is a cofactor for hydroxylation of proline and lysine amino acids in procollagen molecules, which is required for cross-linking collagen's triple helix.
  • Scurvy therefore leads to unstable collagen and collagen fragility.
    • Leaking of vascular structures
      • Gingival bleeding
      • Petechiae
      • Easy bruising
  • Vitamin C is also required for the disulfide bonding in hair leading to corkscrew appearance of hair.

Clinical Features

  • Gingival bleeding
  • Easy bruising
  • Petechiae
  • Corkscrew hair
  • Perifollicular hemmorrhage

Differential Diagnosis

Petechiae/Purpura (by cause)

Dentoalveolar Injuries

Odontogenic Infections


Vitamin deficiencies


  • Guided by clinical suspicion but confirmed with laboratory analysis of vitamin C levels.


  • Vitamin C supplementation.
