Ellis–van Creveld syndrome

Overview

Board takeaway: Establish cardiac and respiratory status before invasive treatment or sedation; protect malformed teeth and coordinate staged rehabilitation.

Short stature, polydactyly, and ectodermal dental findings should prompt attention to the cardiac and respiratory history.

How does Ellis–van Creveld syndrome affect dental management?

• Heart: Coordinate with cardiology; prophylaxis depends on the cardiac lesion and repair
• Respiration: Assess respiratory reserve before sedation or GA
• Soft tissues: Frenectomy or release of the lip-gingiva fusion when it limits function or hygiene
• Rehabilitation: Prevention plus staged restorative or prosthetic rehabilitation for missing and malformed teeth

What is Ellis–van Creveld syndrome?

An inherited skeletal disorder, commonly related to EVC or EVC2 variants, with short limbs, extra digits, nail and dental abnormalities, and frequent congenital heart defects.

What are the main systemic features of Ellis–van Creveld syndrome?

• Genetics: Chondroectodermal dysplasia; EVC or EVC2, autosomal recessive; common in the Old Order Amish
• Tetrad: Tetrad: short-limbed dwarfism, postaxial polydactyly, ectodermal dysplasia (nails, teeth), congenital heart disease
• Heart: Heart defects in ~60%, most often atrial septal defect or common atrium
• Respiration: Narrow thorax with short ribs can cause respiratory distress in infancy

What oral findings occur in Ellis–van Creveld syndrome?

• Hallmark: Fusion of the upper lip to the maxillary gingiva with multiple frenula and no mucobuccal fold (a hallmark)
• Early teeth: Natal or neonatal teeth
• Tooth defects: Hypodontia (especially mandibular anteriors), conical or small teeth, enamel hypoplasia, taurodontism
• Eruption and occlusion: Serrated alveolar ridge, delayed eruption, malocclusion

For Ellis–van Creveld syndrome, how do you manage natal teeth?

• Retain if stable and feeding unaffected
• Aspiration risk: extraction may be warranted if mobility creates a risk of detachment.
• Riga–Fede ulceration or feeding problems: consider incisal-edge smoothing or extraction after an individualized assessment; ulceration alone is not an automatic extraction instruction. AAPD infant oral health guidance.
• Before extraction: confirm neonatal vitamin K prophylaxis, bleeding history, and medical stability with the pediatrician. Coordinate any cardiac prophylaxis from the actual lesion and procedure, not from the syndrome label
