Abstract:
Background/Objectives: Oral mucosal wounds are frequently encountered in daily dental practice and are often difficult to manage because of continuous exposure to saliva, mastication, and mechanical irritation. This technical note describes the clinical practicality of an oral liquid bandage (ORAPLA) as a film-forming protective barrier for traumatic and surgical oral mucosal wounds. Methods: ORAPLA was applied in four clinical scenarios: a traumatic lip bite injury, a postoperative mucosal defect following leukoplakia excision, a biopsy wound for suspected oral squamous cell carcinoma (OSCC), and aphthous stomatitis. Clinical observations included patient-reported symptom relief, film retention, and the clinical appearance of epithelialization at follow-up (1-2 weeks). Results: In all cases, ORAPLA formed a thin protective film immediately after application and was typically observed to remain on the wound surface for approximately 5-6 h under routine daily activities. Patients reported prompt subjective pain relief, and no adverse events were observed. Epithelialization proceeded without clinically evident secondary infection during the follow-up period. Conclusions: In this small descriptive case series, ORAPLA was feasible to apply, well tolerated, and provided temporary mechanical protection with immediate subjective comfort. Controlled studies using standardized outcome measures are warranted.
