Classification of muscular dystrophy
* Duchenne (DMD/Becker (BMD)
* Most common forms – BMD is milder form
* X-linked recessive, affects **mostly boys**
* Intellectual disability common
* Other forms: Limb-Girdle (LGMD), congenital (CMD), and myopathies, distal (DD), oculopharyngeal (OPMD), Emery-Dreifuss (EDMD), facioscapulohumeral (FSH)
114
Medical management of muscular dystrophy
* Clinical course
* Most DMD patients confined to wheelchair after 12yo, with life expectancy into teens + 20's
* Disease management
* No cure/effective tx
* Physical, respiratory, speech therapy
* Orthopedic appliances, corrective orthopedic sx, assisted ventilation, tracheostomy
* Pharmacology: immunosuppressants, abx for respiratory infections, benzos, calcium antagonists, antiarrhythmias
115
Oral findings w/ muscular dystrophy
* Malocclusion
* Small maximum opening, anterior open bite, excessive interocclusal distance, posterior crossbite, broad/shallow dental arches, open bite
* Poor OH
* Tongue thrusting, mouth breathing
* Weakness of muscles of mastication
* Delayed eruption of permanent dentition
* **Hypoplasia, microdontia, agenesis common**
116
Dental considerations w/ muscular dystrophy
* Consult w/ MD
* May require assistance w/ ambulation + chair positioning
* Diligent suctioning of fluids
* Caution w/ use of vasoconstrictors for patients w/ cardiomyopathy
* Caregivers may need to perform OH
* Severely affected individuals may be better treated under GA
* Caution w/ neuromuscular blocking agents (e.g. succinylcholine) during GA
117
What SHCN conditions may be more susceptible to dental trauma?
ADHD, seizure disorder, developmental/intellectual disability
118
Considerations of patients w/ SHCN w/ dental trauma management
* Use existing trauma guidelines
* Consider patient's condition + ability to tolerate immediate and future tx needs
* Discuss implications w/ parent/caregiver
* Consider consult w/ patient's MD
* Patient's health condition may impact tx outcome (e.g. patients w/ diabetes or immunocompromised status may have delayed or impaired healing response)
* Replantation of avulsed permanent teeth may be contraindicated for patients w/ certain medical conditions
* Severe cardiac disease
* Severe seizure disorder
* Severe immunocompromised patients
* Severe developmental disability
* Protective stabilization (w/ informed consent) may be indicated for emergency assessment + management
* If unable to record radiographs, consider clinical photographs of the injury
119
Replantation of avulsed permanent teeth may be contraindicated for patients w/ which medical conditions
* Severe cardiac disease
* Severe seizure disorder
* Severe immunocompromised patients
* Severe developmental disability
120
SHCN definition
* 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.
* This 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 major life activity.
121
What are the cornerstones of patient-centered health care?
* Flexibility
* Responsiveness
* Continuity
* Comprehensiveness
* Coordination

Down syndrome: dental manifestations
Delayed eruption
Missing and supernumerary teeth -
Malformed Teeth (taurodontism) -
Microdontia
Increased risk of perio (Down syndrome : neutrophil chemotaxis defect)
Low levels of caries
Open Bite
Class III tendency
Appearance of Macroglossia
Fissured tongue
123
Down syndrome: treatment considerations
Cardiac defects (40%)(SBE)-
Atrioventricular septal defect
Leukemia (15x) (AML)
Atlantoaxial instability (contraindication in restraint)
3 copies of chromosome 21 (47 total)
Risk of airway obstruction due to large tonsils/adenoids
Possible reduced risk to infection
124
Other facts about Down syndrome
Increased risk with maternal age, 99% non-heritable
Increased risk after having one child with Down Syndrome
125
Cleidocranial dysplasia: dental manifestations
Delayed exfoliation
Delayed eruption
Impacted teeth
Hyperdontia (supernumerary) Peg like teeth
Taurodontism

Cleidocranial dysplasia: treatment considerations
Runx2 gene mutation
127
Other facts about cleidocranial dysplasia
Underdeveloped/absent clavicles
