Some people may develop redness and burning discomfort in the vicinity of the bandage if they are allergic to eugenol.

  • In order to lower the danger of surgery site infection and bleeding, speed up wound healing, and lessen patients' pain and discomfort, periodontal dressings were devised.
  • The ability of eugenol-based dressings to numb pain and make sites less sensitive made them popular in the past, especially after gingivectomy.
  • Based on its antibacterial qualities, zinc oxide-eugenol dressings appeared to prevent or delay bacterial development. However, it was discovered that eugenol irritated oral mucosal tissues, caused allergic reactions, and caused tissue necrosis, especially in bone, which slowed the healing process.
  • Thus, noneugenol periodontal surgical dressing are preferred.
