Marfan Syndrome-Comprehensive Dental/Surgical Management: Clinical Case Report

To perform minimally invasive and preventive treatment in patients with Marfan syndrome (MFS) with hyperdontia in the upper jaw.

Marfan syndrome is an autosomal dominant genetic disease of the connective tissue that is characterized by manifestations in cardiovascular, musculoskeletal, ophthalmological, and oral structures. The diagnosis of this disease is based on clinical and genetic criteria called the Ghent criteria. Within the oral manifestations, hyperdontia may occur, which corresponds to a numerical variation in the number of normal teeth; it can occur in a single or multiple ways, affecting both jaws unilaterally or bilaterally.

A 6-year-old male patient attended the Dental Care Center of the University of the Americas (CAO/UDLA) for evaluation. The reason for consultation was an anomaly in the shape of the upper central incisor. Clinical examination revealed tooth 21 in the shape of a nail, compatible with microdontia. The periapical radiographic examination determined the presence of supernumerary teeth, and the tomographic examination confirmed the diagnosis of hyperdontia in the definitive central incisors, altering the chronological eruption. Surgery and correction of the alteration are scheduled with the interdisciplinary team.

A successfully planned minimally invasive surgical treatment was performed. The initiation of preventive orthopedic treatment will provide the patient with an appropriate expansion of the upper jaw to provide adequate space for the eruption of their permanent anterosuperior teeth.

Marfan syndrome brings important dental complications to consider and know.
