Study Notes

Oral Health Considerations and Oral Manifestations

Valvular heart disease that compromises cardiac output can lead to signs of hypoxemia and cyanosis of lips and oral mucosa.
Antibiotic prophylaxis should be administered to patients with a history of mitral or aortic valve repair or replacement, infective endocarditis, mitral or aortic regurgitation or stenosis, mitral valvular prolapse with valvular regurgitation, prosthetic heart valves, previous bacterial endocarditis, acquired valvular dysfunction, complex cyanotic congenital heart disease, and surgically constructed systemic pulmonary shunts.

Oral Procedures & Need for Antibiotic Prophylaxis to Minimize Risk of Bacterial Endocarditis

Extractions, periodontal procedures including surgery, subgingival placement of antibiotic fibers or strips, scaling and root planning, implant placement, tooth reimplantation, placement of orthodontic bands (not brackets), endodontic instrumentation, intra-ligamentary injection, prophylactic cleaning of teeth where bleeding is anticipated, and other procedures in which significant bleeding is anticipated require antibiotic prophylaxis.

Cardiovascular Disorders

Dyspnea, chest pain, palpitation, syncope, cough with expectoration and hemoptysis, cyanosis, right hypochondrial pain, swelling of feet, decrease in urine output, gastrointestinal symptoms like anorexia, fullness of abdomen, vomiting, fatigability, fever, diabetes mellitus, and hypertension are common symptoms and history of present illness.

Past History

Rheumatic fever, cyanotic spells, recurrent respiratory infections since childhood, detection of murmur/cardiac lesion at school, recent dental extraction, genitourinary instrumentations, hypertension, diabetes mellitus, ischemic heart disease, or any other significant medical illness are important to consider in past history.

Family History

Hypertension, ischemic heart disease, congenital heart disease, rheumatic heart disease, and sudden death are common family history features.

Personal History

Appetite, weight loss, disturbed sleep, bowel and bladder disturbances, habits such as smoking and alcoholism, and exposure to syphilis are important personal history points.

Treatment History

Nifedipine can cause gingival hyperplasia.

Approach to a Patient of Cardiac Disease - Analysis of Presenting Symptoms

Dyspnea is a significant manifestation of cardiac failure, more common in left-sided heart failure than right heart failure.
Functional grading of dyspnea includes Grade I: no limitation of physical activity but dyspnea occurs on more than ordinary exertion, Grade II: dyspnea on ordinary daily activity, Grade III: dyspnea on less than ordinary daily activities, and Grade IV: limitations of all activities (dyspnea at rest).

Orthopnea

Dyspnea that occurs usually on lying down is orthopnea.
It occurs within minutes of assuming recumbency and may indicate severe left heart failure (pulmonary edema).

Platypnea

Dyspnea that occurs on sitting (upright) rather than lying down position is platypnea.
It may be associated with left atrial myxoma or left atrial ball valve thrombus.

Trepopnea

Breathlessness that occurs only when lying down in a lateral position is trepopnea.
It could be due to ventilation-perfusion relationship alteration in certain body positions.

Abnormal Facial Features and Associated Conditions

Elfin facies (receding jaws, flared nostrils, pointed ears) is associated with supraventricular aortic stenosis.
High arched palate is associated with Marfan Syndrome.
Mitral facies (malar flush and pinkish purple patches over the cheek) is associated with mitral stenosis with decreased cardiac output and systemic vasoconstriction.

Oral Manifestations of Cardiovascular Diseases

Acute macroglossia: the tongue is diffusely enlarged and bright red along its lateral portion.
Acute macroglossia due to Enalapril: swelling of tongue and lips.
Gingival hyperplasia due to Dilantin: similar findings may be seen in patients on nifedipine.
Tangier Disease of the Tonsils: enlarged tonsils with bright orange-yellow streaks ("Tiger Stripes").

Examination of Ear

Presence of a crease in the pinna of the ear is associated with increased incidence of coronary artery disease.

Examination of Eyes

Exophthalmus (bulging eyes): associated with Thyroid artery disease.
Blue Sclera: Osteogenesis Imperfecta with aortic regurgitation.
Roth's Spots (of infective endocarditis): small, white spots surrounded by a hemorrhagic halo in the retina.

Examination of Fingers

Clubbing: thickening and widening of the fingertips, associated with various conditions including heart disease.

Causes of Cardiovascular Disease

Organic Disease of the Heart:
- Myocardial Overload: secondary to hypertension or valve disease.
- Coronary (Ischaemic) Heart Disease.
- Cardiomyopathies.
Endocardial Disease:
- Infective Endocarditis.

Dental Management

Measure and record blood pressure at the initial visit.
Assess the presence of hypertension.
Determine the presence of target organ disease.
Determine dental treatment modifications.

Treatment of Hypertension

Non-Pharmacological Treatment and Lifestyle Modifications:
- Salt restriction.
- Weight reduction.
- Stop smoking.
- Diet modifications: reduce intake of cholesterol and saturated fat, adequate intake of calcium and magnesium.
- Limit alcohol intake.
- Relaxation techniques like yoga and psychotherapy.
- Regular exercise.

Oral Manifestations of Hypertension

There are no recognized oral manifestations of hypertension, but anti-hypertensive drugs can cause side effects such as:
- Xerostomia.
- Gingival overgrowth.
- Salivary gland swelling or pain.
- Lichenoid drug reactions.
- Erythema multiforme.
- Taste sense alteration.
- Paresthesia (tingling sensation).

Coronary (Ischemic) Artery Disease

Atherosclerosis is the most common cause of coronary artery disease (CAD).

Etiopathogenesis of Coronary Artery Disease

Risk factors include:
- Lipids (especially HDL).
- Hypertension.
- Diabetes mellitus and glucose intolerance.
- Cigarette smoking.
- Lifestyle and dietary factors.
- Exercise.
- Obesity.
- Vitamins.
- Plasma fibrinogen.
- Endothelial dysfunction.
- Antioxidants.
- Estrogen deficiency.

Diagnosis of Coronary Artery Disease

Clinical Presentation: chest tightness, jaw discomfort, left arm pain, dyspnea, epigastric distress.
Electrocardiogram (ECG/EKG).
Imaging: echocardiography, electrophysiology.
Blood Tests.
Monitoring.

Oral Manifestations of Coronary Artery Disease

Distention of the external jugular veins.
Compensatory polycythemia: ruddy complexion and bleeding tendencies.
Abnormal production of clotting factors.

Dental Aspects of Coronary Artery Disease

Keep the dental chair in a partially reclining or erect position and raise the patient slowly to an upright position.
Emergency dental care should be conservative, primarily with analgesics and antibiotics.
Appointments should be short and non-stressful.
Treat patients in the late morning because epinephrine levels peak in the early morning.
Avoid bupivacaine as it is cardiotoxic.
Use an aspirating syringe to give local anesthetic.
Avoid large doses of epinephrine-containing local anesthetics in patients taking beta-blockers.
Avoid gingival retraction cords containing epinephrine.
Antibiotic prophylaxis is required for dental care.
Delay elective dental care for 6 months after a recent myocardial infarction (MI).

Cardiac Arrhythmia

Cardiac arrhythmia (also dysrhythmia) is any condition with abnormal electrical activity in the heart.
The heartbeat may be too fast or too slow.
Two types: Atrial arrhythmia and Ventricular arrhythmia.

Tachycardia

Any heart rate faster than 100 beats/minute is considered tachycardia.

Bradycardia

A slow rhythm (less than 60 beats/minute) can lead to syncope (fainting).

Heart Block

Blockage of cardiac impulses anywhere in the conduction system.

Oral Manifestations Due to Medications

Oral ulcerations.
Xerostomia.
Gingival hyperplasia.

Dental Considerations for Cardiac Arrhythmia

A proper history should be taken.
Stress and anxiety should be minimized.
Appointments should be short.
Use of epinephrine should be minimized.
Proper chair position is important, preferably supine.
At the end of the appointment, the chair should be raised slowly to minimize orthostatic hypotension.
Use of vasoconstrictors should be minimized.
Prophylactic antibiotics before and after treatment may be needed in recently placed pacemaker patients.
