The dentist’s role in diagnosing rare syndromes: Multidisciplinary management of dentoalveolar abscess in a 10-year-old child with Marfan syndrome

Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder caused by mutations in FBN1 gene, characterized by significant cardiovascular pathology and multisystem fragility. A high level of caution is required in managing MFS in pediatric dentistry due to increased risk of infective endocarditis associated with valvular defects. This is a case report of a 10-year-old girl who presented with a submandibular space infection associated with the right mandibular first molar. Clinical evaluation revealed characteristic Marfanoid features, including a dolichocephalic facial profile, arachnodactyly, and the Steinberg sign. The tooth was extracted under strict antibiotic prophylaxis in adherence to American Heart Association guidelines. Following intervention, complete resolution of symptoms and uneventful healing were observed. This case emphasizes the pedodontist’s pivotal role in the identification of orofacial manifestations and the early diagnosis of systemic syndromes. It further highlights the necessity of multidisciplinary coordination to ensure optimal outcomes for vulnerable pediatric patients.
