Mucosal deposit after triamcinolone injection: a case report

While triamcinolone is a highly effective and rapid treatment for oral mucosal ulcers, caution is advised when treating ulcers above the alveolar bone. It is preferred to administer injections in the corresponding vestibular groove near the buccal mucosa, which has a rich blood supply, rather than above the alveolar bone. Otherwise, reducing the dosage or switching to a more easily absorbable corticosteroid, such as dexamethasone, may be carefully recommended.
