physically handicapped children
TRANSCRIPT
PHYSICALLY HANDICAPPED
CHILDREN
AAPD (2013) -“any physical, developmental, mental, sensory, behavioral,
cognitive, or emotional impairment or limiting condition that requires medical
management, health care intervention, and/or use of specialized services or
programs. The condition may be congenital, developmental, or acquired
through disease, trauma, or environmental cause and may impose limitations
in performing daily self-maintenance activities or substantial limitations in a
major life activity. Health care for individuals with special needs requires
specialized knowledge, as well as increased awareness and attention,
adaptation, and accommodative measures beyond what are considered
routine.”
Special Health Care Needs
2
DEFINITION
DENTAL HANDICAP-
AAPD (1996) states: a person should be considered dentally
differently-abled if pain, infection, or lack of functional
dentition affects following :
1. Restricts consumption of a diet adequate to support
growth and energy needs.
2. Delays or alters growth and development.
3. Inhibits performance of any major life activity including
work, learning, communication and recreation.
DISABLED PERSON (AMERICANS DISABILITIES ACT of
1990)
An individual is disabled if the person:
1. Has a physical or mental impairment that
substantially limits one or more major life activities.
2. Has a record of such an impairment
3. Is regarded as having such an impairment3
Common oral health problems in special health
care needs children
1. Delayed, accelerated or inconsistent tooth eruption
2. Dental caries
3. Periodontal disease
4. Malocclusion
5. Abnormal oral habits – bruxism, mouth breathing, tongue thrusting,
food pouching, picking at the gums
6. Tooth anomalies like- variation in size, shape and number of teeth
7. Trauma and injury4

CLASSIFICATION
FRANK AND WINTER (1974)
•Blind or partially sighted
•Deaf or partially deaf
•Educationally subnormal
•Maladjusted
•Epileptic
•Physically differently-abled
•Defect of speech
•Senile
Nowak(1964)
•Physically differently-abled = polio
•Mentally differently-abled = retardation
•Congenital = cleft palate
•Metabolic = juvenile diabetes
•Systemic= hemophilia
•Convulsive = epilepsy
•Communication = deafness
•Osseous disorders = rickets
•Malignant disorders = leukemia
Holloway and Swallow(1982)
•Mental handicap
•Physical handicap
•Medical disability
Agerholm(1975)
• Intrinsic handicap –one from which person cannot be separated
•Extrinsic handicap – person can be removed ( social deprivation)
New classification
•Developmentally disabled
•Medically compromised
1. INTELLECTUAL DISABILITY
(MENTAL RETARDATION)
It is defined by the American Association of Mental Deficiency (AAMD)-
Sub/average general intellectual functioning, which originates during the
developmental period and is associated with impairment in adaptive
behavior.
MD is the most common developmental disability that can be idiopathic and
challenging.
Mental Retardation: is defined as an overall intelligence quotient lower than
70, associated with functional deficit in adaptive behavior, such as daily-
living skills, social skills communication. Three levels of impairment were-
1. Idiot- development arrested at age 2 years old
2. Imbecile- development equivalent to 2 - 7 years old at maturity.
3. Moron- development equivalent to 7-12 years old at maturity.
Standard formula for
computing IQ

CLINICAL MANIFESTATIONSTensely reclined head, abnormal behaviour, and poor
mobility
Retained primitive reflexes and delayed milestones
Increased tone in limbs and persistent fisting
Hand preference during first 2 yrs of life.
11
ORAL MANIFESTATIONS
• Advanced cases of Early Childhood Caries because of poor oral
hygiene and cariogenic diet patterns.
• Present with multiple anomalies of facial structures also eruption
time, sequence, number, presence of malocclusion and enamel
hypoplasia.
• Also higher prevalence of periodontal disease
Treatment Considerations
The dentist must first asses the child’s mental level so as to gauge the level of
cooperation to be expected and make adjustments accordingly -
1. Short attention span, restlessness, hyperactivity and erratic emotional
behavior characterize MR patients undergoing dental treatment.
2. Familiarize MR patients to the dental office and dental staff so as to reduce
his /her fear before undertaking any dental treatment.
3. Allow the patient to bring one favorite item into the clinic.
4. Speech must be slow, simple.
5. Only one instruction at a time should be given.
6. Reward patient with compliments after the procedure is completed.
7. Carefully listen to these patients as they have difficulty in
communicating.
8. Appointments should be short and scheduled during the early part of
the day.
9. Children should be managed with a blend of kindness and firmness.
10. Permanent restorations and preventive procedures with regular visits.
11. TSD and TLC approach in mild cases whereas sedation in moderate
cases.
12. GA is advised in severe cases where any level of cooperation cannot
be achieved.
Treatment Considerations
2. DOWN’S SYNDROME
Described by John Langdon Down (1865)
One of the most recognizable malformation syndromes.
Occurs due to Trisomy of chromosome 21(95%),
translocation (4%) and mosaicism (1%) .
Incidence/ prevalence –
1 in every 600 live births.
Prenatally diagnosed (from 3% to 60%) in younger patients.
Birth prevalence has declined from 1986 to 2004 (study
done in Australia).
Predisposing Factors
Mother’s age –
If 20 then 1 in 2300
If 34-39 then 1 in 280
If 45-50 then 1 in 45

Dental Treatment
• These children are MR (10%) and require appropriate treatment.
• Incidence of cardiac disease associated with DS is 40% and will require
adequate prophylaxis
• Increased incidence of Leukemia and acute and chronic infections of the URTI
can also alter treatment.
• Children are usually affectionate & cooperative. Do not present problems
during management.
• N2O analgesia or TSD in mildly apprehensive patients can be used; GA in
severe cases.
• Preventive procedures along with CHX may be beneficial.
• Pulp treatment in deciduous teeth is contraindicated in cardiac patients
because of the risk of bacteremia, whereas it can be considered with an
adequate apical seal.
3. CEREBRAL PALSY
• Most severely handicapping condition affecting childhood.
• Definition- Non-progressive lesion which occurs in the developing brain
before, after or during birth leaving the child with a variety of neurological
problems.
• American Academy for Cerebral palsy & Developmental Medicine- A group
of disorders of the development of movement and posture, causing activity
limitations that are attributed to nonprogressive disturbances that
occurred in the developing fetal or infant brain.
• 50% of these children die in infancy or require institutional
care.
• Condition manifests itself as a number of neuromuscular
dysfunctions and involves muscle weakness, stiffness,
paralysis, poor balance, irregular gait and uncoordinated or
involuntary movement.
• I in 200 live births is affected.
Etiology
• Due to decreased oxygenation in the developing
brain leading to damage of the brain
• Complications of labor or delivery
• Infections of the brain like meningitis, encephalitis
• Toxemia of pregnancy
• Congenital defects of the brain
• Kernicterus
• Any trauma to the head
• Premature birth with CNS abnormality are the
common causes.
• Child Abuse
27
SPASTIC
• More than 60-70% of cases
• Cause – lesion in cerebral cortex
• Tendency for muscles to maintain a state of contraction
and for antagonists to lengthen, producing flexion
deformities, particularly in the large joints.
• Limited control of head muscles – ‘HEAD ROLL’
• Spastic quadriplegia associated with convulsions and MR
• Increased motor tone- stiffness
• Impaired chewing and swallowing
• Hypertonicity of facial muscles
• Slow jaw movement
• Hypertonic orbicular muscles
• Spastic tongue thrust
• Drooling of saliva
• Constricted mandibular and maxillary arches
• Usually Class II Div 2 malocclusion, with
unilateral posterior crossbite
Clinical
Manifestations
28
Oral
Manifestations
• Child may have gastro oesophageal
reflux as well as episodes of
vomiting. Leading to dental erosion
or loss of tooth structure.
• Gingival overgrowth due to seizure
medications.
• Abnormalities of muscle tone
• Delayed milestones
• No control over movements
• Muscle weakness
• Spasticity, loss of coordination.
• Retention of primitive reflexes
• Poor development of gross and
fine motor control
Dental Problems
DENTAL CARIES-
Higher caries rate then normal children due to their inability to
maintain good oral hygiene, or due to parents tendency to overindulge
Soft cariogenic diet, Due to increased prevalence of Enamel
hypoplastic defects on their teeth.
PERIODONTAL DISEASE-
Occurs with a great frequency as the patient is unable to brush or
floss.
Also on Phenytoin to control seizure activity which is a cause of some
degree of gingival hyperplasia.
MALOCCLUSIONS-
occurs twice as often.
Protrusions of maxillary anterior teeth, excessive overjet and overbite,
open bites, and unilateral cross bites.
Also Class II Div 2 maloccusion is observed.
BRUXISM-
Atheoid cerebral palsy resulting in severe attrition, loss of vertical
dimension and TMJ.
TRISMUS-
Due to susceptibility to trauma.
Excessive drooling and difficulty in swallowing.
Dental Treatment
• Through medical and dental history should be taken.
• Maintain a calm friendly and professional atmosphere with patient.
• Many patients prefer to be treated in wheelchair which can be
tipped back into dentist’s lap.
• Patient’s head should be stabilized throughout procedure and back
should be elevated to reduce swallowing problems.
• Use physical restraints judiciously for control of extremities.
• Mouth props and finger splints
• Sudden noises and light can stimulate the startle reflex
reactions in patient
• LA be used with care & stabilization against sudden movement.
• Rubber dam used to protect working area from hyperactive
tongue movements.
• Gauze sheilds
• Premedication can be used to reduce hypertonicity, anxiety.
• GA is used as a last resort.
4. EPILEPSY
• Group of disorders characterized by chronic, recurrent and
paroxysmal changes in neurologic function caused by
abnormalities in the electrical activity of the brain.
• Etiology-
Idiopathic
Symptomatic- pathology of the brain due to malformation,
injury or disease.
Prevalence
• <1%
• 75% no
known
etiology
• Higher
frequency in
males
Classification
1. PARTIAL OR FOCAL SEIZURES-
1. SIMPLE PARTIAL SEIZURES
2. COMLPLEX PARTIAL SEIZURES
3. SECONDARY GEN. PARTIAL SEIZURES
2. PRIMARY GENERALIZED SEIZURES-
1. TONIC-CLONIC (GRAND-MAL)
2. TONIC
3. ABSENCE (PETIT-MAL)
4. ATYPICAL ABSENCE
5. INFANTILE SPASMS
3. STATUS EPILEPTICUS-
1. TONIC - CLONIC STATUS
2. ABSENCE STATUS
4. RECURRENT PATTERNS-
1. SPORADIC
2. CYCLIC
3. REFLEX
ABSENCE SEIZURES CONSISTS OF –
Sudden cessation of the ongoing conscious activity without
convulsive muscular activity or loss of postural control.
Brief lapses of consciousness or awareness.
Lasts for a few seconds to minutes.
6-14 years old, common.
TONIC-CLONIC SEIZURES OF-
Starting without warning.
Sudden loss of consciousness, a tonic contraction of the muscles, loss
of postural control, respiration arrests and patient becomes cyanotic,
pupils dilate, eyeballs roll upwards or to the side, face becomes
distorted.
After 30-sec tonic phase followed by clonic phase of several minutes
duration wherein the muscles are violently contracted, with profuse
salivation, perspiration and involuntary bladder and bowel evacuation.
Contractions become less violent and gradually cease. Child then
remains stuporous and goes into a deep sleep.
Oral manifestations of Epilepsy
Injuries caused by the fit-
Soft tissue lacerations of the tongue or buccal mucosa.
Facial fractures.
Trauma to the teeth- avulsion, luxation, fractures.
Subluxation of the TMJ.
Injuries due to drug therapy-
Gingival hyperplasia
Recurrent aphthous like ulceration
Small teeth, delayed eruption
Cervical lymphadenopathy.
Secondary infections of the fibrous overgrowth due to neglection.
Dental Management
1. Complete medical history be acquired regarding type & frequency of
seizure episodes prior to treatment.
2. Reduce stress on patients with sedation. Diazepam is drug of choice
because it has anticonvulsant properties
3. Use of dental chair light is avoided.
4. Avoid seizure promoting drugs such as phenothyazines, IV local
anaestheitcs.
5. Appropriate drug therapy for seizures.
6. Due to use of antiepileptic medication (dialntin sodium), typical gingival
fibrous gingival hyperplasia may occur. Surgical removal be done. Child’s
physician be consulted.
Office management of Seizures
1. If seizure occurs on dental chair, chair is lowered to a supine position.
The patient is protected from injuring himself by moving sharp objects
way, wrapped tongue blade is placed to prevent tongue bite.
2. Mouth prop can be used to prevent tongue biting.
3. Patient be shifted so that he/she cannot harm himself.
4. Maintain a patent airway.
5. Suction may be useful to avoid aspiration of secretions.
6. If convulsions don’t stop then DIAZEPAM 1mg/kg IV be given slowly
upto 10mg. Give oxygen.
7. If condition doesn’t improve admit in hospital.
Dental Treatment
• Appointments should be kept short.
• Importance of oral hygiene maintenance by brushing twice
daily.
• If Appliances are indicated then for tooth movement or tooth
replacement then fixed type only are advised.

5. CHILDHOOD AUTISM
Autism is a mental condition present from early childhood,
characterized by great difficulty in communicating and
forming relationship with other people and in using
language and abstract concepts.
• Etiology: Genetic -3 to 8 % recurrence risk if a family
already has a autistic child.
• Syndromes- Fragile- X, Rett syndrome.
• Medical conditions- tuberous sclerosis complex.
• Prenatal factors- intrauterine rubella, cytomegalo
disease.
• Postnatal factors- infantile spasm, herpes simplex.

ManifestationsClinical:
• Inability to read and comprehend the feelings.
• Delayed language development, echolalia (repeating words).
• Repetitive motions, strict adherence to routines, attachment to
unusual objects.
• Self injurious behaviours.
Dental Findings
• Higher susceptible to caries.
• Bruxism
• Non- nutritive chewing
• Erosion
• Damaging oral habits such as tongue thrusting, lip biting.
• Gingivitis and poor oral hygiene
• Texture sensitivity - it leads to consumption of refined and high sugar diet.
TREATMENT
44
• Allow autistic child to bring comfort items such as toys.
• Make a first appointment short and positive.
• Approach the child in quiet, non-threatening manner.
• Avoid loud noises.
• Invite child to sit alone in dental chair to become familiar with
treatment setting.
• Talk in direct , short phrases . Talk calmly.
• Behaviour modifications technique that is use of positive
reinforcement to promote desirable behaviour.
• Some autistic child can be calm by moderate pressure by using a
papoose board to wrap the child.
