Characteristics of the odontological management of patients with progressive ossifying fibrodyplasia

Introduction: Progressive ossifying fibrodysplasia (POF) is a rare autosomal dominant disease characterized by the congenital malformation of the big toes and progressive postnatal heterotopic ossification of soft tissues with characteristic anatomical profiles. The maxillofacial region may also be affected. Observation: A 24-year-old man was referred by a traumatologist for the restoration of the oral cavity. He showed characteristic signs of POF. Oral clinical examination showed limitation of the oral opening, multiple dental caries, dental necrosis, and an asymptomatic impacted 48. Management included motivation for oral hygiene, scaling and dental extractions, followed by a prescription of steroidal anti-inflammatory drugs at a single dose of 2 mg/kg/day for 4 days. Discussion: The management of patients with POF in oral surgery has particularities. Dental care must be performed in brief sessions. The patient must be in a semi-sitting position, with the neck held upright, to avoid hyper extension of the neck and to improve comfort and safety. A prescription for corticosteroids is necessary after dental care to prevent possible heterotopic ossification. Through this article, we highlight the characteristics of POF, therapeutic attitude, and precautions to take to avoid possible complications.
