An odontogenic cutaneous sinus tract (OCST) is a complication of pulp necrosis and chronic periapical (PA) infection. It spreads to the skin surface through a sinus tract, creating diagnostic and therapeutic challenges for dentists and dermatologists. In pediatric patients, due to the thinner bone cortex, it may appear more rapidly and can lead to significant complications if left untreated. This case explains the management of a chronic cutaneous sinus tract. The tract was associated with pulp necrosis of the mandibular first molar and was treated via non-surgical root canal treatment (RCT) assisted with laser irradiation. Follow-up appointments confirmed the complete resolution of the sinus tract and the radiographic lesion.
