Special Patients


I.  Autism and ASD
-4 to 1 boys over girls. Disorder where children undergo abnormal brain development from early infancy.
A.  Autism-severe language problems, lack of interest in others, repetitive behaviors, irrational routines
B. Asperger-strong verbal skills, trouble with social situations, obsessive interests
C.  PDD (Pervasive Developmental Disorder)-"atypical autism," kids have less severe social impairments
D. CDD (Childhood disintegrative disorder)-normal development 2-4 years, then symptoms develop
E. Rett Disorder: similar pattern to CDD but occurs earlier and in girls mostly

Early indicators:  doesn't respond to name, acts as though were deaf, doesn't smile socially, doesn't point or gesture by age 1, no babbling
Common Meds: Tegretol, Clonidine, Prozac, Ritalin

Dental Management:
-No specific anomalies, but occlusal attrition common due to bruxing
-desensitization (least anxiety-producing to most), lots of positive reinforcement, physical restraint if needed, keep sentences short/simple, possibly use music as an aid, keep environment familiar-same room, same people present if possible.

-most common neurobehavioral disorder in children, typically presenting by age 7.  9% males, 3% females
-main symptoms: inattention, hyperactivity, impulsivity; school difficulties, difficult interpersonal relationships, low self esteem, aggression
-Diagnosis: specific criteria in DSM-IV, present in two or more settings
-Tx: target outcomes to guide management coordinated between child, family, school, physician
     *Stimulant meds: Methylphenidate (Ritalin), dextroamphetamine (Adderall)
           -xerostomia possible side effect
     *Behavioral therapy at home and at school
Dental: Discuss tx and behavior management in detail with parents. Review meds. Pt takes meds day of appt. Lots of positive reinforcement

III. Seizure Disorders
-Spontaneous uncontrollable excessive discharge of cerebral neurons
-Epilepsy=recurrent seizures
-seizures before age 2 usually caused by high fevers
-Classification: Partial, generalized.  (Most common generalized is tonic-clonic)

-medical management: anti-convulsant meds, ketogenic diet, surgery
Dental precautions: meds can have side effects (gingival hyperplasia, gingival bleeding, xerostomia)
   -xylocaine decreases seizure threshold
Management of a seizure: note when it begins, STAY CALM, move everyone away, position pt to prevent injury (nothing in mouth, supine), post ictal airway support, suction airway, vitals

IV. Neural Tube Defects
-Causes: folic acid deficiency (most common), IDDM, maternal epilepsy meds, maternal obesity

3. Myelomeningocele: most severe form, meninges protrudes as a sac through vertebrae
-paralysis, incontinence, hydrocephalus (90%)
Tx: infant surgery (doesn't correct nerve damage), shunt for hydrocephalus (SBE prophylaxis for VA or VV shunt), latex allergy precautions

V. Cerebral Palsy

-Leukemia – 2 major types
            1. Acute Lymphoblastic Leukemia: 75%
            2. Acute Non-Lymphocytic Leukemia: 19%
            -Highest incidence rate in children 1-4 years
            -Overall survival rate: 80% for ALL, 50% for ANLL

Other childhood cancers
-3rd most common form of childhood cancer
-Hodgkin’s and non-Hodgkins
-Sympathetic nervous system tumors
          -97% were neuroblastomas
-Soft tissue sarcomas
          -Rhabdomyosarcoma – most common soft tissue sarcoma

Oral complications of chemotherapy and radiotherapy
-Mucositis, secondary infections, salivary gland dysfunction, bleeding, mucosal/muscular fibrosis, osteoradionecrosis, soft tissue necrosis, TMD, craniofacial and dental developmental problems, oral graft vs host disease

Oral and dental management
-All dental care should be completed before therapy starts. When that is not feasible, prioritize procedures and place temporary restorations until the patient is stable.
-ENDO: extract primary teeth if prognosis of pulpotomy/pulpectomy is questionable
-ORTHO: if poor OH, remove appliances
-PERIO: extract 3rd molars to prevent pericoronitis
-OMFS: extractions done  at least 7-10 days prior

Hematological considerations:
-ANC > 1,000: no need for antibiotic prophylaxis
-ANC < 1,000: defer elective dental care until ANC rises, discuss antibiotic prophylaxis with PCP
-Platelet count >75,000: no additional support needed
-Platelet count 40,000 – 75,000: platelet transfusions may be considered
-Platelet count <40,000: defer care unless emergency cases

Dental considerations during immunosuppression periods

New Morbidities- AAPD Handbook

New Morbidities
Jessica Wilson
5-8% teenage population. "Term" labor: 36-42 weeks. Low birth weight: <2500g.
common oral findings: pregnancy gingivitis, perio disease, pregnancy granuloma, dental erosion and sensitivity, dental caries, and increased tooth mobility.
Pregnancy itself is no reason to postpone routine and necessary dental care. Emergency/needed tx ideal between 14-20th week as the patient may have morning sickness in the first trimester and physical discomfort in third.
Decreasing maternal cariogenic bacterial load with use of fluoride, chlorhexadine and xylitol important, as well as infant oral health anticipatory guidence.
FDA category B drugs may be used during pregnancy: Penicillin, amoxicillin, clindamycin, acetaminophen, ibuprofen and 2% lido w/ 1:100,000 epi.
Obesity & Eating Disorders:
Obesity: BMI > 95th percentile. Overweight: BMI >85th percentile.
Health related concerns: type II diabetes, perio disease, hypertension, cardiovascular disease, psychological distress, respiratory, orthopedic and hepatic problems.
Eating disorders: ~90% female, highest mortality rate of any mental illness.
Anorexia nervosa characterized by BMI <5%. Many anorexia patients brush their teeth vigorously to remove any trace of calorie intake which may cause abrasion of enamel, cervical cementum and gingival recession. Bulimia patients may present with dental erosion, sharp incisal edges, parotid gland swelling with apparently normal salivary flow, thermal sensitivity, callus formation and soft palate injury from induced vomiting.
Abused, Neglect, Missing/Exploited Children:
Epidemiology: Annual incidence reported cases ~3million. Non-reported to reported is 100:1. 1,000-2,000 die annually in the US. 50% children under 7 years old. 30-65% injuries are to the head/neck area.
Dental/Oral findings: bite marks, burns, fractured or displaced teeth, jaw fractures, multiple injuries in various stages of healing, oral/peri-oral gonorrhea.
Substance Abuse:
Overindulgence in and dependence on a stimulant, depressant, chemical substance, herb or fungus leading to effects that are detrimental to an individual’s health or welfare of others. Approximately 50% of US high school students will experiment with at least one illicit drug before graduating. Using alcohol and tobacco at a young age increases risk of using other drugs later.
Youth at risk: family history of substance abuse, depressed, low self-esteem, those who feel that they do not fit in.
Warning signs: fatigue, lasting cough, personality change, irritability, low self-esteem, withdrawing from family, dramatic change in dress and appearance.
Almost 25% children are current smokers by the time they leave high school (males>females). 10% male high school boys report past-month use of spit tobacco. 90% of adult smokers began before the age of 18. Leukoplakia, which can lead to oral cancer, occurs in more than half of all spit tobacco users in the first 3 years of use.
5As Intervention to treat Tobacco Dependence:
Anticipate by educating parents about smoking.
Ask if they have tried tobacco.
Advise about short-term consequences, to be prepared to refuse tobacco and to stop if they have started.
Assess readiness to stop.
Arrange for follow-up, offer tobacco-free messages at each visit.

-widespread hives, angioedema, tongue/lip, cough, wheeze, vomiting, diarrhea- monitor vitals q15min, 0.01 mg/kg IM epi q15min x 2 doses, 1-2 mg/kg IM or IV diphenhydramine, call 911 if life-threatening reactions or LOC occurs.
Allergic Rhinitis:
-Inflammation of nasal mucous membranes resulting from an IgE-mediated allergic rxn to the protein/glycoprotein of inhaled aeroallergens
Tx: intranasal corticosteroids, antihistamines, decongestants
Dental considerations: in severe cases mouth breathing may predispose to ortho problems (if mouth breathing and no dx, dentist should refer to allergist), nasal airway obstruction may be a concern for sedation dentistry
Atopic Dermatitis:
-Chronic dermatitis characterized by pruritis and relapsing inflammation. Affects infants and young children along extensor surfaces, cheeks, forehead and neck, older children and adults in flexural areas.
Urticaria & Angioedema:
-Urticaria- extremely pruritic, erythematous, raised lesions affecting the superficial dermis layers that blanch with pressure
-Angioedema- similar to urticaria, but swelling is deeper and primarily affects face, extremeties, genetalia and occasionally the tongue.
Tx: Antihistamines and oral steriods
Hereditary Angioedema:
-AD disorder resulting from a deficiency in functional C1 esteraseinhibitor. Edema may be triggered by trauma, medical or dental procedures, emotional stress, menstruation, infections, medications.
Tx: daily prophylactic anabolic attenuated adrogens. NOTE: Epi and antihistamines not useful in managing edema.
Food Allergy:
-Immune response induced by exposure to a particular food protein. May be IgE mediated, cell-mediated or both. Most children outgrowtheir allergies by age 5 with the exceptions of peanuts, tree nuts, fish and shellfish. These patients should carry an epi-pen at all times.
Latex Allergy:
-May present as Irritant contact dermatitis(non-immunologic, 80% of hand dermatitis), allergic contact dermatitis ( delayed hypersensitivity, T cell mediated response), or immediate allergic reaction (IgE mediated).
-Asthma is the most common chronic medical condition of childhood. It is most common in African Americans and urban dwellers, particularly those of lower SES.
-Dx: use of spirometry (>6yo) or peak flow measurements (>4yo).
Dental Considerations: These patients may experience increased prevalence of caries and tooth wear, oral candidiasis, decreased salivary flow rates and gingivitis from mouth breathing.
Juvenile Arthritis:
-Can be divided into systemic arthritis, pauciarthritis (<5 joints), polyarthritis, and psoriatic arthritis.
-Dental considerations: patients usually in chronic pain with overprotective parents, may have limited movement including the cervical area and TMJ. They may have difficulty cleaning their teeth if hands or arms involved.
Vasculitides in Children:
-Wegener Granulomatosis- systemic vasculitis including nasal or oral inflammation, ulcers, bloody discharge and subglottic stenosis. Extremely rare in children.
-Bechet’s Disease- apthous ulcers, often extensive and multiple, genital ulceration, cutaneous lesions, ocular disease. Very rare in children.
Systemic Lupus Erythematosus:
-Chronic inflammatory disorder of unknown cause, rare in childhood.
_Dental considerations: increased susceptibility of infection, may require antibiotic prophylaxis for secondary heart damage, xerostomia.
Congenital and Acquired Immunodeficiencies:
-Dental considerations: Aggressive prevention, may need CBC, white cell differential and platelets prior to any invasive dental procedure, extract pulpally involved teeth to prevent septicemia.
