Study Notes
Neurological Diseases
- Neurological diseases affect the neuromuscular system, with a lifetime prevalence rate of 3% to 5%.
- Every oral healthcare provider will encounter patients with these conditions.
- Neurological conditions can impact oral health and dental management decisions.
Seizure Disorders
- Epilepsy is a brain disorder due to excessive neuronal discharge.
- Seizures can involve unusual body movements, loss or altered consciousness.
- Transient episodes of motor, sensory, or psychic dysfunction may occur, sometimes with convulsive movements.
- Epilepsy prevalence is around 1% in the general population.
- 75% of cases have no known cause.
- Higher frequency in males.
Seizure Disorder - Clinical Features
- Seizures are classified as partial or generalized.
- Partial seizures affect only a part of the brain; can be subtle and awareness remains intact.
- Complex partial seizures involve awareness impairment.
- Generalized seizures affect the entire cortex, ranging from absence (impaired consciousness, staring, and eye blinking), to atonic (abrupt muscle tone loss and collapse), myoclonic (sudden jerking of arms and legs), and tonic-clonic (loss of consciousness, repetitive jerking, and sustained stiffening).
Seizure Disorder - Diagnosis
- Neurological history and physical examination, MRI, CT, and electroencephalography (EEG) are essential for diagnosing seizure disorders.
Seizure Disorder - Management
- Pharmacological therapy (antiepileptic drugs) is crucial for epilepsy treatment with minimal side effects.
- The goal is choosing the most effective drug for a specific seizure type.
Seizure Disorder - Oral Health Considerations
- Patients with epilepsy are at increased risk for dental caries, oral trauma, lacerations (including bite injuries to the tongue), and ulcerations/glossitis from B-12 deficiency, induced by medications.
- Trauma-induced TMJ disc dislocation and tooth avulsions are also possible.
- Medication-induced gingival hyperplasia, and delayed healing may occur.
- Seizure triggers and control are key factors for proper patient care.
- Dental patients with epilepsy should have meticulous oral hygiene and appropriate management in severity cases, potentially with surgical reduction.
- Powered toothbrushes may be too stimulating for some patients.
- Fixed prosthetics are preferred over removable ones, avoiding choking concerns.
- Mouth guards may be beneficial.
- Patients on tube feed have low caries, rapid calculus buildup, GERD, high sensitivity, and risk of aspiration in dental chair.
- Low water intake, high suction, and suitable patient positioning are essential.
- For xerostomia, manage oral hygiene (brushing, flossing, and nutrition), use fluoride-containing dentifrice before bed, a neutral 1.1% fluoride gel, and avoid rinsing after brushing and eating/drinking before bed.
- Consider stimulating saliva production and caries resistance using xylitol mints, lozenges, or gum.
Cerebrovascular Disease
- Cerebrovascular disease damages cerebral blood vessels, leading to impaired cerebral circulation.
- Stroke (CVA) is a sudden impairment of cerebral circulation lasting over 24 hours. This event can lead to death or focal neurological deficits.
- Transient Ischemic Attacks (TIAs) are reversible, acute focal neurological deficits (mini-strokes) within 24 hours.
- Stroke is the second leading cause of death and the third leading cause of disability globally.
- Incidence in Saudi Arabia is 43.8 per 100,000.
Cerebrovascular Disease - Clinical Features
- Stroke symptoms include sensory and motor deficits, weakness, visual problems, sudden headaches, altered mental status, dizziness, nausea, seizures, impaired speech or hearing, memory, reasoning, and concentration deficits.
Cerebrovascular Disease - Diagnosis & Management
- Brain imaging (CT scan followed by MRI), risk factor stratification (diabetes and hyperlipidemia), and acute treatment options (thrombolysis with intravenous tissue plasminogen activator (t-PA)) are essential.
- Chronic treatment often involves daily aspirin and other antiplatelet medications.
Cerebrovascular Disease - Oral Health Considerations
- Assess patients'stroke risk before dental procedures.
- Timing and the complexity of the procedure are important for avoiding complications.
- Patients on Warfarin must report their INR, as therapeutic levels range from 2-3.
- Metronidazole and tetracycline can increase Warfarin's INR.
- Effective pain control during procedures reduces stress and risk factors.
- Local anesthesia with a minimal vasoconstrictor (epinephrine 1:100,000 or 1:200,000, and less than or equal to 0.04mg) is important to reduce risks.
- Oral manifestations can include unilateral facial paralysis, loss of oral sensory stimulus, flaccid tongue, dysphagia, neglected oral self-care on one side, increased caries, periodontal disease, and halitosis.
- Rigorous preventive measures such as 3-month recall appointments and topical fluoride application are recommended.
Parkinson Disease
- Parkinson's disease (PD) is a chronic, progressive neurodegenerative disorder.
- PD results from the degeneration of dopaminergic cells in the substantia nigra, reducing dopamine in the basal ganglia. Prevalence in Saudi Arabia is estimated at 27 per 100,000.
Parkinson Disease - Clinical Manifestations
- Resting tremor, stiffness or rigidity of limbs/trunk, slowness of movement (bradykinesia), postural instability or balance impairment, and coordination problems.
- Also includes dementia, behavioral/psychiatric symptoms(depression, anxiety, apathy, and irritability), autonomic dysfunction (orthostatic hypotension, constipation and urinary problems), and abnormal sweating.
Parkinson Disease - Diagnosis & Management
- Clinical diagnosis.
- Genetic testing for hereditary patterns.
- Treatment focuses on symptom management, not cure. Dopamine replacement therapy using levodopa (combined with carbidopa) remains the initial gold standard.
- Various medications are used for different symptoms.
Parkinson Disease - Oral Health Considerations
- Patients often require treatment in a relatively upright position.
- Dysphagia and impaired gag reflex increase aspiration risk.
- High-speed fluid evacuation is vital to reduce aspiration risk..
- Levodopa and dopamine agonists can cause orthostatic and potentially severe hypertension.
- Monitoring blood pressure and advising slow, staged standing are recommended.
Myasthenia Gravis
- Myasthenia gravis (MG) is a chronic neuromuscular disease caused by autoimmune destruction of the skeletal neuromuscular junction, characterized by episodic weakness of skeletal muscles.
- Weakness worsens with activity and improves with rest.
- Anti-acetylcholine receptor (AChR) antibodies are the most common.
- Prevalence rates are between 15-20 cases per 100,000 in Western countries
Myasthenia Gravis - Clinical Features
- Diplopia (double vision) and ptosis (drooping eyelids), oropharyngeal, facial, masticatory muscle weakness; dysphagia (difficulty swallowing), asymmetry, and dysarthria(difficulty speaking) are key features.
- Disease course often varies, with a generally progressive pattern.
Myasthenia Gravis - Diagnosis & Management
- Clinical examination and medical history are highly suggestive.
- Tensilon (edrophonium) challenge for rapid Ach increase, and serum anti-AChR antibodies are diagnostics.
- Treatment involves plasma exchange and high-dose intravenous immunoglobulin, along with symptomatic treatment.
Myasthenia Gravis - Oral Health Considerations
- High aspiration risk due to potential difficulties with prolonged opening and swallowing.
- Using adequate suction, rubber dams, and avoiding bilateral mandibular anesthesia can mitigate aspiration risks.
- Respiratory crisis may arise from the disease or excessive medication.
- Patients may be best treated in hospital environments to allow possible intubation.
- Avoid drugs affecting neuromuscular junctions (narcotics, tranquilizers, barbiturates).
- Caution with drugs affecting neuromuscular function, like antibiotics (tetracycline, streptomycin, sulfonamides, and clindamycin), and some anesthetics (those metabolized by plasma cholinesterase).
