[2025-10-01T17:45:26.179081] [PI reasoning] **Analyzing potential causes of oral ulcer**

I’m looking into why a child developed a large ulcer near the lower lip after a formocresol pulpotomy on a mandibular molar. It seems likely that postoperative trauma from lip biting could result from residual anesthesia. The rubber dam frame might create pressure at the mouth's corner too. A chemical burn from formocresol is unlikely because it’s usually contained, and an allergic reaction would cause swelling instead of an ulcer. So, I think the best answer is lip biting due to anesthesia loss. Maybe I should verify this with some literature?
