Injuries to oral soft-tissues can occur due to accidental, iatrogenic, and factitious traumas. They may present as burns, ulcerations, and gingival recession. Chemical, thermal, and physical agents are the main causative agents for oral soft-tissues burns. The purpose of this case report was to illustrate the destructive nature of the local behavior and to describe the successful treatment of this case. A 20-year-old girl with severe pain and burning sensation in the left maxillary region, which was interfering with normal eating and speaking, was admitted to periodontology clinic. Upon questioning, the patient readily admitted traumatizing her gingival and cheek mucosa with alcohol. Treatment consisted of oral hygiene instruction, mechanical debridement, local antimicrobial agents, systemic anal- gesic and guidance for patient. The burn lesions in the oral cavity can occur at dental offices and homes. The early detection by the patient and the immediate institution of therapeutic measures ensured a rapid cure and possibly prevented further mucosal damage. In addition, we believe that guidance and education are important prophylactic tools for prevent from these local behavior.
