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.

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
– Others-steroids,

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)
ikassem@dr.com
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) ikassem@dr.com

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
ikassem@dr.com
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
ikassem@dr.com
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
ikassem@dr.com
TREATMENT
MEDICATIONS 1) Nitrates- vasodilator eg: ISDN. ISMN 2) Pain reliever- eg: Morphine 3) Beta-blockers 4) Statins- cholesterol lowering drugs. Eg:
Atorvastatin, Simvastatin
ikassem@dr.com
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!
ikassem@dr.com
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
ikassem@dr.com
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

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
ikassem@dr.com
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

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
ikassem@dr.com
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
ikassem@dr.com
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
ikassem@dr.com
Management for Low-Intermediate Risk
Short appointments
AM appointments
Comfort
Vital Signs Taken
Avoidance of Epinephrine within Local Anesthetic or Retraction Cord
O2 Availability
ikassem@dr.com
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)
ikassem@dr.com
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 ikassem@dr.com
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.
ikassem@dr.com
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
ikassem@dr.com
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
ikassem@dr.com
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
ikassem@dr.com
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 ikassem@dr.com
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 ikassem@dr.com
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 ikassem@dr.com
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.
ikassem@dr.com
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.
ikassem@dr.com
Obese patients tend to have flatter or more concave profiles because of increased mandibular length and increased tissue thickness.
ikassem@dr.com
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.
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.
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.
“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…
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…
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.
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?
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.
Axis I – Clinical Disorders
Dementia**, delirium, amnesia, other cognitive disorders**
Schizophrenia**/other psychoses
Mood disorders**
Substance-related disorders**
Eating disorders**
Somatoform disorders**
Anxiety disorders**
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.
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)
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
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
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)
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.
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).
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)
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)
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.
Schizophrenia-Medication Side Effects
ORAL DYSKINESIAS (drug-induced)
conventional antipsychotics
atypical antipsychotics
antiemetics
antiparkinsonion
TCA‟s
SSRI‟s
lithium
anticonvulsants
antihistamines
methamphetamines
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
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.
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.
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.
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:
clozapine,olanzapine,quetiapine,risperidone
Oral side effects: xerostomia, dysphagia, stomatitis, dysgeusia
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…
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.
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.
SCHIZOPHRENIA Dental Considerations
fluoride supplements (e.g.Prevident)
oral hygiene
salivary substitutes (re: dry mouth)
Clozapine use & agranulocytosis
freq. recall appts.
empathy, support, MD consultation
meds/consent/psych. status
SCHIZOPHRENIA Drug Interactions
Epinephrine used with caution to prevent severe hypotensive episode – limit to 2 carpules 1:100,000; avoid epinephrine in retraction cords; inject slowly.
Neuroleptics may intensify effects of sedatives, hypnotics, opioids, antihistamines – leading to severe respiratory depression – consult with MD.
Neuroleptics can dec. blood levels of warfarin.
COMPLICATIONS OF XEROSTOMIA
acidic plaque pH…caries, hypersensitivity
loss of lubrication…oral ulcerations, difficulties eating, speaking, wearing dentures
dec. amount of saliva…inc. infections (viral, bacterial, fungal) digestion problems, ease of trauma to oral mucosa, gingivitis & periodontitis
DENTAL MANAGEMENT Dry Mouth Protocol
sipping water frequently
restrict caffeine, colas
sugar free gum, candies.
saliva substitutes, oral moisturizers e.g. MouthKote, Biotene products (contain key enzymes[3] found naturally in saliva)
avoid alcohol/alcohol containing mouthrinses
fluoride rinses(0.05%)
fluoride gels(0.04%)
CHX mouth rinse (alcohol-free TBA)
restrict/avoid tobacco products
Depression is…..
“an equal opportunity
illness” –all ages, races, all economic classes.
an illness (as is diabetes, heart disease)
leading cause of suicide (15%)***
F > M: 2:1
highest risk for those with family Hx. Of depression – genetic component, further advanced by emotional deprivation or childhood trauma.
elderly > 65.
those with physical illness/disabilities.
Depression is…..
second leading cause of death and disability in the world in age category of 15-44 yrs. (M & F) – W.H.O.
an illness affecting the entire body
leading cause of alcohol/drug abuse (1/3 of patients)
Depression will be…..
The second leading cause of health impairment worldwide by 2020.
(WHO)
Major Depressive Disorder
Mental illness of at least 2 weeks duration encompassing at least 5 of the following DSM-IV diagnostic symptom criteria:
depressed mood
diminished interest/pleasure
dec./inc. in wt. or appetite
insomnia/hypersomnia
inability to think or concentrate
fatigue/loss of energy
thoughts of death/suicide
Bipolar I Affective Disorder
“ a roller coaster of mood”
lowest of lows = s/s of major depression

ANXIETY DISORDERS
Anxiety – what is it?
“emotional pain or a feeling that all is not well-a feeling of impending disaster”
The physiological reaction/response occurs via ANS- can include inc. heart rate, sweating, dilated pupils, inc. urge of urination, diarrhea.
ANXIETY DISORDERS
may involve an internal psychological conflict, environmental stressors, physical disease, side effects of medications or combination of these findings.
the consequences of anxiety are profound emotional, occupational and social impairments.
ANXIETY DISORDERS Etiology
no single theory available
usually a combination of psychosocial/biological processes (neurobiological theories)
low level anxiety can be “normal” but… anxiety often is a component of other psychological disorders such as mood disorders, dementias, panic disorder, psychoses etc.
ANXIETY DISORDERS

**analgesics, +/- antibiotics
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.”
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.
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.
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.
Somatoform Disorders
Examples of Oral Symptoms
burning, painful tongue
numbness/tingling sensation of soft tissues
facial pain
Somatoform Disorders
PATH TO DIAGNOSIS
symptoms do not follow known anatomic nerve distribution.
lab tests/MD consult have r/o underlying systemic cause e.g. anemia, CA, diabetes.
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.
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.
Eating
Speaking
Esthetics (smiling and self esteem)
The taking of dental
radiographs during
pregnancy continues to be
a controversial issue.
It should be noted,
however, that a pregnant
patient who is properly
shielded can safely
receive dental x-rays at
any time.
You lose a tooth for every pregnancy
Babies drain the calcium from your teeth
Every time you are pregnant your gums bleed and you have problems with them
False to all: Meticulous oral hygiene with fluoride regimen will help to prevent all tooth and gum problems experienced during pregnancy
Oral Disease and Systemic Disorders
Periodontitis has an association with:
• Infective Endocarditis
• Diabetes
• Cardiovascular Disease
• Pre-Term, Low Birth Weight Infants
• Pulmonary Disease
• Others
Oral Disease and Systemic Disorders Periodontitis and pregnancy
Oral Disease and Systemic Disorders Periodontitis and pregnancy
Biologic Mechanisms for PTLBW Infants
Entry of inflammatory products (PgE2, Il-6, TNF- α), endotoxin, and/or periodontal bacteria into the bloodstream and their translocation to the fetus and decidual tissues
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
Review
Recommendations
Regular dental examinations for all pregnant patients
Aggressive periodontal therapy for infections
Frequent reinforcement of oral hygiene and dental care by medical providers
Also know as pyogenic granuloma.
Rare, usually painless lesion, develops on gums in response to plaque
Non-cancerous
•Subside shortly after childbirth
•No treatment is required unless causes problems with eating, speaking, or swallowing
•If treatment is needed, it is surgically removed
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.
If nausea and vomiting is a problem, it is important to frequently brush or rinse with water. The acid could cause erosion of the teeth.
If you are craving sweets, this could cause an increase in cavities. So, just remember to snack on raw veggies and fruits.
