Surgical and mucogingival management of an oral pyogenic granuloma associated with fixed orthodontic treatment in an adolescent patient: a case report.

Oral pyogenic granuloma (OPG) is a reactive vascular lesion that may worsen during orthodontic treatment due to biofilm-induced inflammation. This clinical case describes the surgical and mucogingival management of an OPG associated with fixed orthodontic appliances in an adolescent patient. A 12-year-old male patient presented with an oval, pedunculated lesion with a smooth surface and soft consistency, measuring approximately 8.5 × 6.5 mm, located on the attached gingiva adjacent to tooth #21. Therapeutic management consisted of complete surgical removal of the lesion under local anesthesia; additionally, mucogingival management was performed via partial dissection, lateral displacement, and coronal advancement of the tissue to promote preservation of the gingival architecture. Histopathological examination confirmed the diagnosis of OPG. Adequate healing was observed during clinical follow-up. This case highlights the importance of identifying reactive gingival lesions in young patients with fixed orthodontic appliances, in whom inflammatory and hormonal factors may play a parallel role.
