Cerebral palsy

Also called: CP

Overview

Board takeaway: Plan around positioning, aspiration risk, seizures, and oral-motor dysfunction. Cerebral palsy is a nonprogressive motor disorder from early brain injury.

How does Cerebral palsy affect dental management?

Positioning: Treat in the wheelchair or transfer carefully; support head, trunk and limbs; never force limbs
Bite and startle reflexes: Mouth props and finger guards for the bite reflex; slow, forewarned movements to limit startle
Airway protection: Choose a position compatible with swallowing, breathing, and contractures. Use effective suction and rubber dam when tolerated and feasible; no device eliminates aspiration risk
Sedation risk: impaired swallow, aspiration, seizures and contractures; coordinate the safest setting and airway plan with anesthesia
Prevention: caregiver brushing training, modified brushes, fluoride toothpaste, and risk-based varnish.
Gingival disease: chlorhexidine may be an adjunct; select a safe application method when the child cannot rinse and spit.

What is Cerebral palsy?

A group of permanent disorders of movement and posture caused by nonprogressive disturbances in the developing brain; associated sensory, cognitive, and seizure disorders may also occur.

What are the main systemic features of Cerebral palsy?

Cause and frequency: Prenatal or perinatal brain injury; linked with prematurity and low birth weight; ~2–3 per 1,000 births
Motor patterns: Spastic (70–80%), dyskinetic (athetoid or dystonic), ataxic, or mixed
Associated features: Intellectual disability (~50–60%) is not universal; seizures in 30–50%; vision, hearing and speech deficits
Swallowing and posture: Dysphagia, GERD, aspiration pneumonia; joint contractures and scoliosis
Treatment: Spasticity managed with botulinum toxin, baclofen, physical and occupational therapy, orthopedic surgery
Communication: Motor and speech impairment do not establish intellectual disability; speak directly to the child.

What oral findings occur in Cerebral palsy?

Gingivitis and periodontal disease from poor oral hygiene; phenytoin gingival overgrowth
Caries risk from soft or pureed diets, prolonged oral clearance and dependence on caregivers
Class II, anterior open bite and constricted maxilla from tongue thrust and hypotonia
Bruxism and attrition; erosion from GERD; drooling (sialorrhea)
Hyperactive bite and gag reflexes; dental trauma from falls and seizures

For Cerebral palsy, what do you do when the bite reflex clamps on a mirror?

Do not pull; wait for relaxation and reduce stimulation
For subsequent care, use a properly sized, secured mouth prop when indicated and tolerated. Do not force an instrument between clenched teeth; reassess the plan if the reflex prevents safe treatment

A 10-year-old with spastic quadriplegic CP arrives in a wheelchair. How do you position and stabilize?

Chair: treat in the wheelchair if possible, using a wheelchair headrest or tilt chair.
Transfer: follow the child’s individualized handling assessment, including trained staff and required equipment; do not assume a two-person manual lift is safe. HSE individual handling assessments.
Support: stabilize the head, trunk, and limbs; keep hips and knees flexed, and never force limbs against spasticity.
Startle control: move slowly and warn before touching.

For Cerebral palsy, what is your biggest concern in the operatory and under sedation?

Aspiration risk from impaired swallowing, reflux, or pooled secretions is a major concern when present.

Assess: the child’s actual swallowing and respiratory history.
Protect: position for airway protection; use suction and isolation that can be tolerated.
Sedation plan: seizures, contractures, and airway access also matter. Coordinate with anesthesia when these risks are significant.
