Fetal alcohol spectrum disorders

Overview

Board takeaway: Use short, structured visits and caregiver-supported prevention; review cardiac disease, medications, sensory needs, and consent authority.

Lifelong physical, behavioral, and learning effects of prenatal alcohol exposure. Children may have characteristic facial features, growth deficits, attention and behavior problems, and congenital heart defects.

How do Fetal alcohol spectrum disorders affect dental management?

• Communication: Short, structured visits with clear simple instructions, repetition, and positive reinforcement
• Medical history: Ask about cardiac defects and medications (stimulants for ADHD)
• Consent: Confirm the legal guardian for consent; coordinate with caseworkers when needed
• Prevention: Prevention and caregiver support; recall based on risk
• Sensory support: Screen hearing and vision needs when communicating

What are Fetal alcohol spectrum disorders?

A range of conditions caused by alcohol exposure before birth, affecting growth, the face, and the brain, with lasting effects on learning and behavior. Fetal alcohol syndrome is one diagnosis within the spectrum; support needs and functional impairment vary.

What are the main systemic features of Fetal alcohol spectrum disorders?

• Growth: Growth deficiency before and after birth; microcephaly
• Learning and behavior: Intellectual disability, learning difficulties, ADHD-like symptoms, poor judgment and impulse control
• Associated anomalies: Congenital heart defects (e.g., septal defects), renal and skeletal anomalies in some
• Sensory needs: Hearing and vision problems
• Developmental referral: Prenatal alcohol exposure can disrupt brain and other organ development; provide nonjudgmental support and referral for developmental assessment

What oral findings occur in Fetal alcohol spectrum disorders?

• Face: Smooth philtrum and thin upper lip vermilion; midface hypoplasia
• Associated anomalies: Cleft lip or palate and other congenital anomalies have been reported; an oral finding alone does not establish FASD
• Development: Enamel defects, malocclusion, and delayed eruption reported
• Caries: Caries risk depends on daily hygiene support, diet, fluoride exposure, medications, and access to care; assess these directly
