Description and Cause
Cerebral palsy is “an umbrella term for a group of non-progressive, but often changing, motor impairment syndromes secondary to lesions or anomalies of the brain arising in the early stages of its development” (Kuban and Leviton 1994). Congenital cerebral palsy (90% of cases) may be caused by inadequate blood or oxygen supply to the fetus, illness during pregnancy, premature birth, birth trauma, etc. Acquired cerebral palsy (10% of cases) may be caused in the first few months after birth by head trauma, infections (encephalitis, meningitis, herpes simplex, cytomegalovirus), exposure to toxic substances, severe malnutrition, child abuse, etc. Evidence suggests that cerebral palsy does not result from the hazards of neonatal intensive care, as has been suggested.
1.5 to 2.5:1,000 children by early school age
Classifications of Cerebral Palsy
Although the classification of types of cerebral palsy is not uniform and there is not a standard upon which all clinical observers agree, it can be classified according to the type of abnormal muscle tone or movement, or according to the region of the body involved.
Note: Definitive diagnosis of cerebral palsy may not be possible until 15 to 24 months of age; however, the presence of spasticity, hypotonia, dystonia or athetosis warrants referral for evaluation and treatment services; and the presence of functional delays warrants referral for early intervention services.
- Spastic Cerebral Palsy (50% of cases)
Extremities Involved: diplegia (mainly both lower extremities), quadriplegia (all four extremities plus trunk and neck), or hemiplegia (one arm and one leg on same side of body)
Neurologic Dysfunction: spasticity
- Abnormal persistence of newborn reflexes
- Grasp reflex causing tight fists in infants
- Increasing spasticity and rigidity of limbs
- Diplegia only: may have normal intelligence, difficulty drawing and writing, cross-over of the legs
- Quadriplegia only: seizures, severe mental retardation is usual
- Hemiplegia only: may have average intelligence; seizures
- Athetoid Cerebral Palsy (20% of cases)
Note: There are very few new cases of athetoid cerebral palsy because its primary cause, hyperbilirubinemia, can now be identified and treated at birth.
Extremities Involved: quadriplegia
Neurologic Dysfunction: athetosis, hypotonia
- Weak and “floppy” muscles in infancy
- Appearance of symptoms after 6 months
- Abnormal hand positioning when infant reaches for objects
- Unsteady balance and gait
- Abnormal, involuntary and uncontrollable movements (twitching, twisting, writhing)
- Hearing and speech deficiencies
- Normal intelligence
- Ataxic Cerebral Palsy (10% of cases)
Extremities Involved: atonic diplegia or congenital cerebellar ataxia
Neurologic Dysfunction: hypotonia
- Diplegia only: severe mental retardation
- Ataxia only: mild mental retardation, disturbed balance and depth perception
- Difficulty with rapid or fine movements
- Spasticity in late childhood
- Tremors, unsteadiness, uncoordination and choreic movements
- Mixed Cerebral Palsy: A combination of the three types above.
The likelihood of associated conditions increases with the severity of the underlying Cerebral Palsy and is higher among people with quadriplegia than among those with diplegia or hemiplegia. For example, only a small number of persons with athetoid cerebral palsy have epilepsy because the basal ganglia are primarily involved; in contrast, up to 90% of individuals with spastic quadriplegia have epilepsy because the entire brain is usually affected.
In addition, many of these conditions are secondary results of immobility and therefore may be preventable (such conditions are indicated with a *).
- Mental retardation
- Learning disabilities
- Seizure disorders
- Vision impairment
- Speech impairment
- Hearing impairment
- Tonal problems
- Bladder problems (urinary tract infection)
- Excessive drooling
- Poor nutrition
- Joint contractures
- Hip dislocation
- *Joint, muscle or other pain
- *Skin breakdown
- *Gastrointestinal problems (oral motor dysfunction, gastroesophageal reflux, esophagitis, gastritis, ulcers, constipation)
MEDICAL MANAGEMENT CONSIDERATIONS
back to top
Note: These considerations are in addition to the normal medical care provided to an individual without cerebral palsy. Although many recommendations can be addressed through clinical examination by the primary care provider, a multidisciplinary team approach (primary care physician, neurologist, orthopedist, physical therapist, occupational therapist, pediatric orthotist, nurse, dentist or dental hygienist, social worker) is the standard of care for persons with Cerebral Palsy. Access to specialized multidisciplinary care may be available through California Children Services (CCS) for persons under age 21.

- Consider small, frequent meals
- Consider evaluation for feeding/swallowing difficulties, supervision during oral feeding, and swallowing therapy
- Prescribe anti-ulcer medications, if indicated
- Monitor swallowing function
- Monitor carefully for scoliosis
- Watch closely for signs of pneumonia
- Treat pneumonia with antibiotics; use oxygen or assisted ventilation when necessary
ORAL HEALTH CONSIDERATIONS
back to top
A thorough knowledge of the dental implications of cerebral palsy will aid a primary care provider and dental practitioner in preventing dental problems and providing the most appropriate treatment. Treatment options and limitations, as well as daily measures to take to prevent dental problems and maintain oral health, should be clearly explained to persons with developmental disabilities and their families/caregivers. Dental caries is an infectious and transmissible disease. Every person should have an oral health care plan by age 1 to prevent early childhood caries and later periodontal disease.
Dental Conditions Associated with Cerebral Palsy
- Drooling (10-37%), primarily due to swallowing dysfunction
- Increase in dental caries due to
- Poor oral hygiene, physical difficulty with brushing/flossing teeth
- Soft diet
- Enamel hypoplasia (incomplete development or underdevelopment of the enamel)
- Mouth breathing
- Anti-drooling medications leading to xerostomia
- Use of sugar-laden foods, e.g. soft drinks, jelly beans, etc., throughout the day and evening as behavioral reinforcers
- Retaining food in the mouth longer due to dysphagia
- Use of liquid medications with high sugar content
- Increased risk of periodontal disease due to
- Gingival hyperplasia (gum overgrowth) as a result of phenytoin (Dilantin) therapy
- Poor oral hygiene due to immobility or greater dependence on others and other factors listed above
- Malocclusions due to decreased muscle guidance of erupting teeth
- Tongue thrust
- Dental trauma particularly to anterior teeth, fractured teeth
- Bruxism (compulsive grinding or clenching of the teeth)
- Temporomandibular joint (TMJ) disorders
- Dry lips due to mouth breathing
- Decreased parotid flow rate
Managing the preventive, restorative, and surgical aspects of dental treatment involve an early (by age 1) and regular oral health evaluation and the establishment of a customized oral health care plan. Dental treatment plans should consider the limited motor skills and degree of control of the upper extremities of the patient. In addition, the patient may or may not be able to provide consent for the dental treatment.
Tooth decay (dental caries) is due to a variety of factors including acidogenic bacteria, presence of fermentable carbohydrates, and impaired ability of the saliva to buffer the acid. Fillings alone do not address the bacteria or the poor buffering capacity of the saliva. An appropriate caries risk assessment and an oral health plan are necessary to address the cause of the oral disease, including periodontal disease.
- The approach to dealing with dental decay in persons with cerebral palsy differs little from the general population, including the professional application of sealants, except for the need to involve caregivers in supervising or performing preventive procedures for some individuals.
- Individuals using wheelchairs may need to be transferred from wheelchair to dental chair.
- To protect the airway in patients with swallowing dysfunction or aspiration problems, patients should not be placed in a supine position; placement at a 45-degree angle is acceptable.
- Dental chairs should be moved slowly and movements of the individual�fs head should be minimized to reduce spastic muscle responses.
- Rapid set impression materials are helpful.
- Stabilizing/protective devices or restraints may be needed due to uncontrollable body movement.
- Muscle relaxants, sedation, general anesthesia, or hospitalization may be required to provide treatment. If a sedative is needed, one with a muscle relaxant component is a logical choice.
- Tablets/capsules are often better managed than liquid medications.
- Since patients may be receiving anti-epileptics, medications for spasticity, and/or other drugs, consider drug interactions prior to using additional medications, sedatives, or anesthetics.
- Use of removable prosthetic devices is not contraindicated in people with uncontrolled seizures or ataxia provided those appliances are tooth born, well fitting, and have good retention. Both safety issues and concerns of patient self-esteem should be considered.
- A dentist may consider creating a mouth guard for individuals with seizures to protect the individual�fs teeth in the case of a fall.
- Many people with cerebral palsy who have uncontrolled head movements can nevertheless be treated in a dental office if the dental provider uses good hand and finger rests and positions the patient to be able to move with them.
- Preventive measures include topical fluoride applications, dietary counseling, sealants, and periodic professional prophylaxis.
- Establish a customized oral health care plan that includes good daily oral hygiene procedures including plaque removal by brushing and flossing and the use of adjunct aids as needed, such as various fluoride products, Xylitol, and fluoride varnish.
- Modify usual methods of brushing/flossing teeth for individuals who cannot perform these procedures in the usual manner.
- If patient will not cooperate with brushing, teach caregiver to use desensitization by starting with some wet gauze or a washcloth on the mouth and gradually moving to a soft, dry toothbrush, then a wet toothbrush, and finally a toothbrush with toothpaste.
- Modify toothbrush, use specially designed toothbrushes or floss holders with modified handles to facilitate grasping. A toothbrush or floss holder handle can be modified to make it easier to grasp by pushing the handle through a rubber ball or by attaching the handle to a bicycle grip with plaster of Paris.
- Instruct caregivers to position the individual on a couch with their head in the caregivers lap to assist the individuals needing help to remove plaque. Use a lightly moistened brush without toothpaste and use a floss holder for patients who cannot rinse/expectorate or perform these procedures themselves.
- Promote diet that does not increase the risk of dental decay (e.g., reduces the regular exposure to fermentable carbohydrates, etc.).
- Consider diet counseling for a patient with significant tooth decay.
- Consider diet consistency and sugar content of liquid medications.
- Avoid prolonged use of bottles containing fermentable carbohydrates and provide instructions to never put a child to sleep with a bottle containing fermentable carbohydrates.
- Use fluoridated water and toothpaste. Recommend daily fluoride tablets or drops if water supply does not contain recommended amount of fluoride.
- Use gum, mints, or foods containing Xylitol as the primary sugar to reduce caries.
- Use antimicrobial (Chlorhexidine) mouthwash or spray as an adjunct for some individuals with rampant caries and gingivitis.
