Diabetes

[email protected]

Page 3: Medical problems 2 4

DEFINITION DIABETES MELLITUS

An endocrine disorder in which there is insufficient amount or lack of insulin secretion to metabolize carbohydrates.

It is characterized by hyperglycemia, glycosuria.

[email protected]

Page 6: Medical problems 2 4

Diabetes Mellitus Pathophysiology

The beta cells of the Islets of Langerhan of the Pancreas gland are responsible for secreting the hormone insulin for the carbohydrate metabolism.

Remember the concept - sugar into the cells.

Diabetes Mellitus Types

Type 1 - IDDM

– little to no insulin produced

– 20-30% hereditary

– Ketoacidosis

Gestational

– overweight; risk for Type 2

Type 2 - NIDDM

– some insulin produced

– 90% hereditary Other types include Secondary

Diabetes : – Genetic defect beta cell

or insulin – Disease of exocrine

pancreas – Drug or chemical

induced – Infections-pancreatitis

Coronary Heart Disease: Myocardial Ischemia

Decreased blood

supply (and thus oxygen) to the myocardium that can result in acute coronary syndromes: – Angina pectoris (

Stable ) – Unstable Angina – Myocardial infarction – Sudden death (due to

fatal arrhythmias)

[email protected]

Page 52: Medical problems 2 4

Ischaemic heart disease Definition

An imbalance between the supply of oxygen and the myocardial demand resulting in myocardial ischaemia.

Angina pectoris symptom not a disease chest discomfort associated with abnormal

myocardial function in the absence of myocardial necrosis

Supply – Atheroma, thrombosis, spasm, embolus

Demand – Anaemia, hypertension, high cardiac output

(thyrotoxicosis, myocardial hypertrophy) [email protected]

Warning Signs and Symptoms of Heart attack

1) Pressure, fullness or a squeezing pain in the center of your chest that lasts for more than a few minutes.

2) Pain extending beyond your chest to your shoulder, arm, back or even your teeth and jaw.

3) Increasing episodes of chest pain 4) Prolonged pain in the upper abdomen 5) Shortness of breath- may occur with or without chest

discomfort 6) Sweating 7) Impending sense of doom 8) Lightheadedness 9) Fainting 10) Nausea and vomiting

[email protected]

Page 67: Medical problems 2 4

Angina Pectoris At least 70% occlusion of coronary

artery resulting in pain. What kind of pain? – Chest pain – Radiating pain to:

Left shoulder Jaw Left or Right arm

Usually brought on by physical exertion as the heart is trying to pump blood to the muscles, it requires more blood that is not available due to the blockage of the coronary artery(ies)

Is self limiting usually stops when exertion is ceased

[email protected]

Page 68: Medical problems 2 4

Clinical Patterns of Angina Pectoris

Stable - pain pattern and

characteristics relatively unchanged over past several months (better prognosis)

Unstable - pain pattern changing

in occurrence, frequency, intensity, or duration (poorer prognosis); MI pending

[email protected]

Page 69: Medical problems 2 4

TREATMENT

MEDICATIONS 1) Nitrates- vasodilator eg: ISDN. ISMN 2) Pain reliever- eg: Morphine 3) Beta-blockers 4) Statins- cholesterol lowering drugs. Eg:

Atorvastatin, Simvastatin

Page 70: Medical problems 2 4

Ischaemic heart disease Relevance to Dentistry

IHD is common

Subjects with IHD have more severe dental caries and periodontal disease – association or causation?

Angina is a cause of pain in the mandible, teeth or other oral tissues

Stress provokes ACS!

[email protected]

Page 71: Medical problems 2 4

Myocardial Infarction

Partial or total occlusion of one or more of the coronary arteries due to an atheroma, thrombus or emboli resulting in cell death (infarction) of the heart muscle

When an MI occurs, there is usually involvement of 3 or 4 occluded coronary vessels

[email protected]

Page 72: Medical problems 2 4

Chest Pain Myocardial ischaemia

Site Jaw to navel, retrosternal, left submammary Radiation Left chest, left arm, jaw….mandible, teeth, palate Quality/severity tightness, heaviness, compression…clenched fists Precipitating/relieving factors physical exertion, cold windy weather, emotion rest, sublingual nitrates Autonomic symptoms sweating, pallor, peripheral vasoconstriction,

nausea and vomiting

Page 73: Medical problems 2 4

Chest Pain Differential diagnosis

Cardiac pathology – Pericarditis, aortic dissection

Pulmonary pathology – Pulmonary embolus, pneumothorax, pneumonia

Gastrointestinal pathology – Peptic ulcer disease, reflux, pancreatitis, „café

coronary‟

Musculoskeletal pathology – Trauma, Tietze‟s Syndrome

Page 74: Medical problems 2 4

Acute Myocardial Infarction Assessment

30% of deaths occur in the first 2 hours.

(Cardiac muscle death occurs after 45 mins of ischaemia)

Symptoms and signs of myocardial ischaemia

Also

– Changes in heart rate /rhythm

– Changes in blood pressure [email protected]

Page 75: Medical problems 2 4

Acute Myocardial Infarction Treatment

Stop dental treatment

Call for help

Rest, sit up and reassure patient

Oxygen

Analgesia (opiate, sublingual nitrate)

Aspirin

Thrombolysis

Primary angioplasty

Beta-Blockers

ACE inhibitors

Prepare for basic life support

[email protected]

Page 76: Medical problems 2 4

Surgical Treatment

Percutaneous Transluminal Coronary Angioplasty (PTCA)

– balloon expansion that can provide 90% dilitation of vessel lumen

[email protected]

Page 77: Medical problems 2 4

Stent Placement

With use of just the balloon, re-occlusion of the artery can occur within months

Placement of a stent delays or prevents re-occlussion

[email protected]

Page 78: Medical problems 2 4

Surgical Treatment

Coronary Artery By-Pass Graft (CABG)

The graft bypasses the obstruction in the coronary artery

Graft sources: – saphenous vein

– internal mammary artery

– radial artery

[email protected]

Page 79: Medical problems 2 4

Acute Myocardial Infarction Complications

Sudden Death (18% within 1 hour, 36% within 24 hours)

Non-fatal arrhythmia Acute left ventricular failure Cardiogenic shock Papillary muscle rupture and mitral

regurgitation Myocardial rupture and tamponade Ventricular aneurysm and thrombus Distal Embolisation

[email protected]

Page 80: Medical problems 2 4

Sudden Death

Sudden Cardiac Death is also known as a “Massive Heart Attack” in which the heart converts from sinus rhythm to ventricular fibrillation

In V-Fib, the heart is unable to contract fully resulting in lack of blood being pumped to the vital organs

V-Fib requires shock from defibrillator “SHOCKABLE RHYTHM”

Dental Considerations

Assessment and Overall Management

Pharmaceuticals

Emergency Situations

Oral Effects of Pharmaceuticals

Antibiotic Prophylaxis

Post MI: when to treat

Consider three areas: – How severe or stable the ischemic heart

disease is

– The emotional state of the patient

– The type of dental procedure

[email protected]

Page 82: Medical problems 2 4

RISK

Major Risk for Perioperative Procedures: – Unstable Angina (getting worse)

– Recent MI

Intermediate Risk for Perioperative Procedures: – Stable Angina

– History of MI

Most dental procedures, even surgical procedures fall within the risk of less than 1%

Some procedures fall within an intermediate risk of less than 5%

Highest risk procedures those done under general anesthesia

[email protected]

Page 83: Medical problems 2 4

Management for Low-Intermediate Risk

Short appointments

AM appointments

Comfort

Vital Signs Taken

Avoidance of Epinephrine within Local Anesthetic or Retraction Cord

O2 Availability

[email protected]

Page 84: Medical problems 2 4

Dentistry & Cardiovascular Medicine

AMI – GA within 3/12 of AMI: 30% re-infarction rate

@ 1/52 post op

– Avoid routine LA dental treatment for 3/12 (emergency treatment only)

– Avoid excess dosage, reduce anxiety

– Avoid elective surgery under GA for1 year (specialist)

– Be aware of medications (bleeding, hypotension)

[email protected]

Page 85: Medical problems 2 4

Post MI: When to Treat Why delay treatment?

– Remember that with an MI there is damage to the heart, be it severe or minimal that may effect the patient‟s daily life

MI within 1 month Major Cardiac Risk

MI within longer then 1 month:

– Stable routine dental care ok

– Unstable treat as Major Cardiac Risk

Older studies suggest high re-infarction rates when surgery performed within 3 months, 3-6 months… however, this was abdominal and thoracic surgery under general anesthesia

New research suggests delaying elective tx for 1 month is advisable. Emergent care should be done with local anesthetic without epinephrine and monitoring of vital signs

When in doubt:

– CONSULT THE CARDIOLOGIST [email protected]

Page 86: Medical problems 2 4

Dental Management Correlate

Elective dental care is ok if it has been longer than 4-6 weeks since the MI and the patient does not report any ischemic symptoms.

If there is any doubt or question, consult with the cardiologist.

[email protected]

Page 87: Medical problems 2 4

Common Situations:

– Orthostatic Hypotension due to use of anti-hypertensives (beta blockers, nitroglycerin…)

Raise chair slowly

Allow patient to take his/her time

Assist patient in standing

– Post-Op Bleeding:

When patients on Plavix or Aspirin, expect increased bleeding because of decreased platelet aggregation

Dental Considerations for IHD

[email protected]

Page 88: Medical problems 2 4

Dental Considerations for IHD

Emergent Situations:

– Possible MI:

Remember that pain in the jaw may be referred pain from the myocardium assess the situation, have

good patient history, follow ABC‟s

– Angina:

In situations of angina pectoris, all operatories should have nitroglycerin to be placed sublingually

[email protected]

Page 89: Medical problems 2 4

Dental Considerations for IHD

Emergent Situations:

– Chest Pain-MI:

STOP PROCEDURE

Remove everything from patient‟s mouth

Give sublingual nitroglycerin

Wait 5 minutes if pain persists, give more

nitroglycerin, assume MI

101

Give chewable aspirin ABC‟s

[email protected]

Page 90: Medical problems 2 4

Dental Management: Stable Angina/Post-MI >4-6 weeks

Minimize time in waiting room

Short, morning appointments

Preop, intra-op, and post-op vital signs

Pre-medication as needed – anxiolytic (triazolam; oxazepam); night before and 1 hour before

– Have nitroglycerin available – may consider using prophylacticaly

Use pulse oximeter to assure good breathing and oxygenation

Oxygen intraoperatively (if needed)

Excellent local anesthesia - use epinephrine, if needed, in limited amount (max 0.04mg) or levonordefrin (max. 0.20mg)

Avoid epinephrine in retraction cord [email protected]

Page 91: Medical problems 2 4

Dental Management: Unstable Angina or MI < 3 months

Avoid elective care

For urgent care: be as conservative as possible; do only what must be done (e.g. infection control, pain management)

Consultation with physician to help manage

Consider treating in outpatient hospital facility or refer to hospital dentistry

ECG, pulse oximetry, IV line

Use vasoconstrictors cautiously if needed [email protected]

Page 92: Medical problems 2 4

Intraoperative Chest Pain Stop procedure

Give nitroglycerin

If after 5 minutes pain still present, give another nitroglycerin

If after 5 more minutes pain still present, give another nitroglycerin

If pain persists, assume MI in progress and activate the EMS

– Give aspirin tablet to chew and swallow

– Monitor vital signs, administer oxygen, and

be prepared to provide life support [email protected]

Page 93: Medical problems 2 4

Conclusion: When treating patients with Ischemic Heart

Disease or recent MI…

– Use caution and common sense

– When in doubt:

CONSULT THE CARDIOLOGIST

Obesity

orthodontist will have between 1 in 6 and 1 in 5 patients who are clinically overweight or obese, depending on the state or region in which he or she practices.

[email protected]

Page 95: Medical problems 2 4

Cephalometric and facial analyses should be altered when examining obese or overweight patients. These patients tend to have larger mandibles and shorter upper face heights that could change potential treatments.

[email protected]

Page 96: Medical problems 2 4

Obese patients tend to have flatter or more concave profiles because of increased mandibular length and increased tissue thickness.

[email protected]

Page 97: Medical problems 2 4

Psychosocial problems are likely the rule with

obese patients. The clinician should monitor for problems such as depression and anxiety, because these conditions tend to be more likely in obese patients.

CHRONIC MENTAL ILLNESS “an equal opportunity illness affecting all ages, all races, all economic groups and both genders”

Chronic mental illness and it‟s medical management carry inherent risks for significant oral disease.

Page 107: Medical problems 2 4

How common is Mental Illness?

“disorder” ---- impairment is key

concept of risk factors can considered as potential important clues or as the “weak links” in the mental health chain.

Page 108: Medical problems 2 4

STATISTICS - Suicide male: female – 3:1 300 teens(10-19 yrs) commit 530,000 kids have treatable MI but only

150,000 get treatment. highest rates: 43/100,000 > 80 yrs. 30/100,000 > 75 yrs.

Page 109: Medical problems 2 4

“No one chooses to have a mental disorder…………”

….admitting to mental illness is not the same thing as admitting to any other serious health issue since it can often result in more suspicion than support…

…misconceptions flourish…

Page 110: Medical problems 2 4

Mental Health Fact…..

… people with a psychiatric illness experience a “double–burden” which includes both the s/s of the disease + the social stigma, isolation, discrimination that result from having that disease…

…stigma=social isolation, homelessness, unemployment, substance abuse, prolonged institutionalization…

Page 111: Medical problems 2 4

Dental Perspectives…..

Medications used to treat mental illness can interact with drugs used in dentistry.

Some oral health problems arise as manifestations of mental illness.

Oral health problems as side effects of psychotropic medications.

Decreased compliance to oral health care/ability to obtain or tolerate oral care treatment.

Page 112: Medical problems 2 4

Dental Perspectives…..

Sample Mental Health History

What psychiatric medications are you taking?

How long have you been taking the medication and does it help?

What are/were your symptoms?

When was your mental

illness diagnosed? Who is the

GP/Psychiatrist treating this condition?

Have you experienced any dental side effects, such as dry mouth, burning tongue, excessive saliva or swollen gums?

Page 113: Medical problems 2 4

DSM IV – Diagnostic & Statistical Manual of Mental Disorders

a “descriptive” approach to diagnosis based on symptoms rather than causes. The disorders listed include a “clinical significance” criterion re: significant distress or impairment.

there is no blood test, brain scan or specific x-ray to make a diagnosis as with other medical problems.

Page 114: Medical problems 2 4

Axis I – Clinical Disorders

Dementia**, delirium, amnesia, other cognitive disorders**

Schizophrenia**/other psychoses

Mood disorders**

Substance-related disorders**

Eating disorders**

Somatoform disorders**

Anxiety disorders**

Page 115: Medical problems 2 4

WHAT IS A PSYCHOSIS?

Psychosis is a disordered pattern of thought, perception, emotion and behaviour. The psychotic person has a bizarre sense of reality, with emotional and cognitive impairment leading to loss of function in the environment.

Page 116: Medical problems 2 4

SCHIZOPHRENIA

~1- 2% worldwide. late teens/early adulthood;

gradual/sudden. M (earlier) > F 10%= chronic hospitalization; 30-40%

long-term serious handicap. 40% risk of suicide attempts 60% alcohol abuse/15-25%street drugs 20% shorter life expectancy(>vulnerability

to medical problems (lifestyle)

Page 117: Medical problems 2 4

SCHIZOPHRENIA Etiology

Causation of schizophrenia remains not well understood (syndrome?). Theories include:

(genetics) altered expression of genes(10-15% with one parent; 30-40% - 2 parents

differences in brain chemistry-(imbalances in neurotransmitters, e.g. dopamine)

differences in brain structure

Page 118: Medical problems 2 4

SCHIZOPHRENIA Etiology

Schizophrenia is NOT:

• a multiple or “split” personality

• caused by bad parenting/character flaws

• the result of childhood trauma

• an isolated condition: 1 in 100 incidence?

• an automatic precursor to criminal violence

Page 119: Medical problems 2 4

SCHIZOPHRENIA Symptomatology

1. Positive symptoms: does not mean “good” but rather s/s that are present but shouldn‟t be there. Exaggeration, distortion of normal function, e.g. delusions (control of one‟s thoughts, actions) hallucinations (sensory: auditory- [patient hearing “voices”]

visual, tactile)

Page 120: Medical problems 2 4

SCHIZOPHRENIA Symptomatology

2.Disorganized symptoms: a rapid

shift of ideas, incoherent speech, poor

thought relation. Disorganized, bizarre

behaviour e.g. stereotypical, imitation

of others speech, gestures etc.

Page 121: Medical problems 2 4

SCHIZOPHRENIA Symptomatology

3. Negative symptoms: the absences of behaviour that should be there. i.e. flat emotions/emotional expression, lack of motivation, monotony of speech apathy, social withdrawal, absence of normal drives or interests such as those involving one‟s self care (general/oral).

Page 122: Medical problems 2 4

SCHIZOPHRENIA Medical Management

“Conventional” Antipsychotics (Neuroleptics)

chlorpromazine(Thorazine), methotrimeprazine (Nozinan), haloperidol(Haldol),

early 1950s; blocking of dopamine D2 receptors in the mesolimbic system of the brain affecting mood & thought processes; e.g. effective in managing “positive” symptoms only….

major side effect: *movement disorders*[oral dyskinesias] - often with orofacial component. Arise from blockade of basal ganglia dopamine D2 receptors in extrapyramidal system (EPS)

Page 123: Medical problems 2 4

Schizophrenia-Medication Side Effects

ORAL DYSKINESIAS Abnormal involuntary, uncontrollable

movements affecting primarily the tongue, lips, jaws (can extend to trunk/limbs)

Causes: 1. drug induced( conventional antipsychotics)**

2. neuropsychiatric conditions 3. edentulousness (**tardive dyskinesia)

Page 124: Medical problems 2 4

Schizophrenia Medication Side Effects

Tardive Dyskinesia (TD)

late stage effect of slow, rhythmic involuntary

grimacing/twitching in facial area e.g. repeated

smacking of lips, tongue movements, facial

contortions.

>25% of patients on conventional antipsychotics

having TD after 5 years of treatment.

Ironically, the signs of TD reinforce the

“crazy” stereotype, which in reality is only

a side effect of treatment.

Page 125: Medical problems 2 4

Schizophrenia-Medication Side Effects

ORAL DYSKINESIAS (drug-induced)

conventional antipsychotics

atypical antipsychotics

antiemetics

antiparkinsonion

TCA‟s

SSRI‟s

lithium

anticonvulsants

antihistamines

methamphetamines

Page 126: Medical problems 2 4

Schizophrenia-Medication Side Effects

ORAL DYSKINESIAS-Complications

tooth wear

oral pain/injury

TMJ degeneration

speech impairment

chewing difficulties

inadequate food intake…wt. loss

displacement/poor

retention of RPD‟s…decreased tolerance

social sequelae

Page 127: Medical problems 2 4

Schizophrenia Medication Side Effects

Side effects of movement disorders are often

managed by Rx. anticholinergic medications

e.g. Cogentin. These drugs in turn exhibit

their own spectra of side effects.

Other side effects include EKG changes,

orthostatic hypotension, dry mouth,

constipation, blurred vision, nasal stuffiness.

Page 128: Medical problems 2 4

Schizophrenia Medical Management

“atypical antipsychotics”

First appeared in late 1980s; e.g.

clozapine(Clozaril), risperidone(Risperdal),

olanzapine(Zyprexa), quetiapine(Seroquel).

*rarely cause movement disorders* why? – these

drugs possess a high ratio of serotonin to D2

activity and are therefore referred to as serotonin-

dopamine antagonists vs. conventional

antipsychotics or “dopamine antagonists.”

Schizophrenia Medical Management

CLOZAPINE

remains the drug of choice in treatment resistant cases; reduce cravings for alcohol/illicit drugs; reduced/delayed risk of suicide attempts.

But 1% of patients develop agranulocytosis after 12-24 wks. Patients required to have weekly WBC counts i.e. > 3000/c.c.

can cause initial sialorrhea; hypotension, sedation, tachycardia.

Page 130: Medical problems 2 4

Schizophrenia Medical Management

Risperidone, Olanzapine, Quetiapine

-provide better management of both

“positive”,“negative” & “disorganized” symptoms.

Minor sedation, weight gain, sexual dysfunction, dry mouth, no agranulocytosis.

**the improved clinical course and therefore compliance with these “atypical” medications ensure less chances for relapse that was seen with conventional antipsychotic therapy.

Page 131: Medical problems 2 4

Schizophrenia Medical Management

BUT, atypical antipsychotics can compound at patient‟s risk for diabetes, heart disease, obesity, hyperlipidemia (“metabolic syndrome”)

Dental implications are relevant with respect to clinical management of the diabetic, cardiac patient etc.

Antipsychotic Medications: Impact on Dental Care

Conventional Antipsychotics:

chlorpromazine, haloperidol, perphenazine

Oral side effects: xerostomia, tardive dyskinesia

Atypical Antipsychotics:

Schizophrenia Oral Findings

…people who suffer from schizophrenia are at a far greater risk of dental caries, gingivitis/advanced periodontal disease, tooth loss, lack of dentures, poor oral hygiene, mucosal diseases…

+ poor dietary habits, smoking, alcohol

abuse, substance abuse…

Page 134: Medical problems 2 4

Schizophrenia Oral Findings

higher prevalence of bruxism and signs of TMD = severe tooth damage due to extensive attrition.

? CNS abnormalities and/or neuroleptic induced mechanisms.

actual pain sensitivity thresholds higher in pats. with schizophrenia vs. healthy controls. While more prone to suffer TMD problems, pain sensitivity thresholds cause delays in dx. and tx. resulting in serious clinical consequences.

Page 135: Medical problems 2 4

Schizophrenia Oral Findings can be….

precipitated by the psychosocial deficiencies inherent in the disease itself.

a result of a disinterest in regular oral care; is due to financial hardships, prolonged periods of hospitalization and non-existent support networks.

also a result of an unwillingness on the part of the DDS to understand and/or be comfortable in the dental management of these patients.

Somatoform Disorders

“Psychological disorders characterized by the presence of physical symptoms that are not fully explained by a medical condition, the effects of a substance, or by another mental disorder.”

Page 190: Medical problems 2 4

Psychosomatic vs. Somatoform

– Psychosomatic: disorders in which there is REAL physical illness that is largely caused by psychological factors such as stress and anxiety.

– Somatoform: disorders in which there is an APPARENT physical illness for which there is no organic basis.

Page 191: Medical problems 2 4

Somatoform Disorders

Patients may experience multiple, unexplained somatic symptoms that may last for years.

Examples:

hypochondriasis

Pre-occupation with fear of having a serious disease on the basis of one‟s misinterpretation of bodily symptoms/bodily functions.

conversion disorder

Patient resolves an underlying conflict (“primary gain”) by the unconscious use of the symptom(s). (e.g. conversion paralysis/blindness) Increased attention as a result = secondary gain.

Page 192: Medical problems 2 4

Somatoform Disorders

body dysmorphic disorder “pre-occupation with an imagined or exaggerated

defect in physical appearance”

One of the underlying causes of patient dissatisfaction with certain physical or dental features such as the appearance of teeth, facial asymmetry or disproportion of shape and size of lips, mouth or jaw.

Page 193: Medical problems 2 4

Somatoform Disorders

Examples of Oral Symptoms

burning, painful tongue

numbness/tingling sensation of soft tissues

facial pain

Somatoform Disorders Medical Perspective

psychiatric Tx. re: somatoform disorders focuses on coping vs. cure.

anxiety/depression contribute to s/s in 33% of patients with SD. Treatment of these conditions will facilitate management of somatoform disorders.

psychotherapy, SSRI‟s.

Page 196: Medical problems 2 4

CONCLUSION Dental Perspectives for patients diagnosed with mental illness

Some patients who undergo psychiatric care for e.g. depression may be reluctant to admit this fact due to the stigma attached to the psychiatric diagnosis.

Dentistry must overcome such barriers: obtain all relevant information

supportive, non-judgmental attitude

ensuring confidentiality

emphasizing the need to be provided safe dental care.

American Academy of Periodontology Report 2004

•Preventive oral care services should be provided as early in pregnancy as possible.

•If exam indicates a need for periodontal therapy, these procedures should be scheduled early in the 2nd trimester.

•The presence of acute infection, abscess, or other potentially disseminating sources of sepsis may warrant prompt intervention, irrespective of the stage of pregnancy.

Dental Considerations

Preterm Low Birth Weight Births

Smoking, alcohol use, and drug use contribute to mothers having babies that are born prematurely at a low birth weight.

Evidence suggests a new risk factor – periodontal disease.

Pregnant women who have periodontal disease may be seven times more likely to have a baby that is born too early and too small.
