INTRODUCTION
• Diabetes mellitus represents a spectrum of metabolic disorders and has emerged as a major health issue worldwide.
• It is a complex metabolic disease characterized by:
Chronic hyperglycemia,
Diminished insulin production,
Impaired insulin action, or a combination of both
• Result in the inability of glucose to be transported from the bloodstream into the tissues, which in turn, results in high blood glucose levels and excretion of sugar in the urine.
Alteration in lipid and protein metabolism.

DEFINITIONS
• International Diabetes Federation (IDF) describesDiabetes as a chronic disease that arises when thepancreas does not produce enough insulin, or whenthe body cannot effectively use the insulin it produces.
• According to Carranza, DM is defined as a complexmetabolic disorder characterized by chronichyperglycaemia, diminished insulin production,impaired insulin action or a combination of both resultin the inability of glucose to be transported from theblood stream into the tissues, which in turn results inhigh blood glucose levels and excretion of sugar in theurine.

HISTORY
• Diabetes is one of the first diseases described with an Egyptian
manuscript from 1500 BC mentioning “too great emptying of
the urine.”
• The term diabetes was probably coined by Apollonius of
Memphis around 250 BC, which literally meant “to go
through” or siphon as the disease drained more fluid than a
person could consume. Later on, the Latin word “mellitus”
was added because it made the urine sweet.

• Sir Frederick Grant Banting, Charles Herbert Best and
colleagues purified the hormone insulin from bovine pancreas
at the University of Toronto. Leading to the availability of an
effective treatment—insulin injections and the first patient
was treated in 1922.
• For this, Banting and laboratory director John MacLeod
received the Nobel Prize in Physiology or Medicine in 1923.

EPIDEMIOLOGYAccording to International Diabetes Federation (2012), there are more than 371
million people in world who have diabetes. The number of people with diabetes isincreasing in every country in which half of people with diabetes are undiagnosed. Theestimate of the actual number of diabetics in India is around 40 million.

CLASSIFICATIONS
National Diabetes Data Group(1979)- on the basis of age at onset and type of therapy:
• TYPE I- Insulin dependent DM (IDDM) or Juvenile Diabetes
• TYPE II- Non insulin dependent DM (NIDDM) or Adult onset Diabetes
![Page 9: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/9.jpg)
American diabetic association(1997)
DM is classified on the basis of pathophysiologyof DM into 4 categories:
1. Type 1
2. Type 2
3. Other Specific types of DM
4. Gestational diabetes

OTHER SPECIFIC TYPES
• Those associated with diseases that involve the pancreas and
destruction of insulin producing cells.
• Endocrine diseases such as acromegaly, tumors,
pancreatectomy and drugs or chemicals are included.
![Page 15: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/15.jpg)
GESTATIONAL DIABETES
• Under normal conditions insulin secretion is increased by 1.5 to 2.5 fold during pregnancy reflecting a state of insulin resistance
• Gestational diabetes develops in 2% to 5% of all pregnancies but disappears after delivery.
• Women who have had gestational diabetes are at increased risk of developing type 2 diabetes later in life.
• It usually has its onset in the third trimester of pregnancy and adequate treatment will reduce perinatal abnormality.

URINE TESTING
1. GLUCOSE
Testing the urine for glucose with dipsticks is a common screening
procedure for detecting diabetes.
2. KETONES
Ketone bodies can be identified by the nitroprusside reaction,
which measures acetoacetate, using either tablets or dipsticks.
3. PROTEIN
Standard dipstick testing for albumin detects urinary albumin at
concentrations > 300mg/L

INFECTIONS IN PATIENTS WITH DIABETES
Mainly due to:• Impaired defence mechanism 1. Defects in PMN function2. Induction of insulin resistance3. Vascular changes
Hyperglycemic state
Glycosylation of basement
mem, proteins
• Thickning of gingival capillaries,
• Disruption of BM
Swelling of Endothelium
1. Oxygen diffusion
2. Metabolic waste elimination
3. PMN Migration
4. Diffusion of serum factors

WOUND HEALINGWound Healing is Affected as cumulative effect of:
•Altered cellular activity•Decreased collagen synthesis
•Glycosylation of existing collagen
•Increase collagenase production
Readily degrade newly synthesized, less completely cross linked collagen
•Reduced Collagen solubility•Delayed remodelling of wound site
Defective Healing

BACTERIAL ASSOCIATION• Glucose content of GCF & blood is higherin diabetics.
• Results in changed environment fo the microflora
• Presence of higher levels of specific microorganisms such asActinobacillus actinomycetemcomitans and Capnocytophaga .(Mashimo et al 1983)
• The proportion of P gingivalis was reported to be higher in non-insulin-dependent diabetes mellitus patients with periodontitis.
• This may be due to the abnormal host defense mechanisms inaddition to hyperglycemic state can lead to the growth ofparticular fastidious organisms. (Zambon et al,1988)
![Page 36: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/36.jpg)
EFFECT OF DIABETES ON PERIODONTITIS
Data of multiple studies reveal strong evidence
•Diabetes is a risk factor for gingivitis &
periodontitis.
•The level of glycemic control appears to be an
important determinant in this relationship.
Cianciola et
al
1982 In children with type 1 diabetes, the prevalence of gingivitis was greater than in
non-diabetic children with similar plaque levels.
Sastrowijot
o S et al
1990 Improvement in glycemic control may be associated with decreased gingival
inflammation.
Papapanou
PN
1996 Majority of the studies demonstrate a more severe periodontal condition in
diabetic adults than in adults without diabetes.
Tsai C et al 2002 In a large epidemiologic study in the United States, adults with poorly controlled
diabetes had a 2.9-fold increased risk of having periodontitis compared to non-
diabetic adult subjects; conversely,well-controlled diabetic subjects had no
significant increase in the risk of periodontitis.
Salvi GE et
al
2005 Rapid and pronounced development of gingival inflammation in relatively well-
controlled adult type 1 diabetic subjects than in non-diabetic controls, despite
similar levels of plaque accumulation and similar bacterial composition of plaque,
suggesting a hyperinflammatory gingival response in diabetes.
![Page 37: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/37.jpg)
EFFECT OF PERIODONTAL DISEASE ON DIABETES
• Periodontal diseases can have a significant impact on the
metabolic state in diabetes. The presence of periodontitis
increases the risk of worsening of glycemic control over time.
Williams RC Jr.,
Mahan CJ.
1960 Type 1 diabetic patients with periodontitis had a reduction in required insulin
doses following scaling and root planing, localized gingivectomy, and selected
tooth extraction combined with systemic procaine penicillin G and streptomycin
Taylor GW et al 1996 In a 2-year longitudinal trial, diabetic subjects with severe periodontitis at
baseline had a six-fold increased risk of worsening of glycemic control over time
compared to diabetic subjects without periodontitis
Rodrigues DC
et al
2003 Better improvement in glycemic control in a diabetic group treated with scaling
and root planing alone compared to diabetic subjects treated with scaling and
root planing plus systemic amoxicillin/clavulanic acid.
Promsudthi A
et al
2005 In older, poorly controlled type 2 diabetic subjects who received scaling and root
planing plus adjunctive doxycycline showed a significant improvement in
periodontal health but only a non significant reduction in HbA1c values.

MECHANISM BY WHICH PERIODONTAL DISEASE MAY INFLUENCE DIABETES
Acute bacterial and viral infections
Chronic gram-negative periodontal infections have significantly higher serum markers of inflammation such as c-reactive protein (CRP), IL-6, and fibrinogen than subjects without periodontitis.
Periodontal treatment may reduce inflammation locally and also decrease serum levels of the inflammatory mediators that cause insulin resistance, thereby positively affecting glycemic control
![Page 39: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/39.jpg)
EFFECTS OF DIABETES ON THE RESPONSE OF PERIODONTAL THERAPY
• Many diabetic patients show improvement in clinical
parameters of disease immediately after therapy, patients with
poorer glycemic control may have a more rapid recurrence of
deep pockets and a less favorable long-term response.
• Further longitudinal studies of various periodontal treatment
modalities are needed to determine the healing response in
individuals with diabetes compared to individuals without
diabetes.

CURRENT MEDICAL MANAGEMENT OF DIABETES MELLITUS
1. DIET : The goals of this intervention includeweight reduction, improved glycemic control,with blood glucose levels in the normalrange, and lipid control.
2. Exercise : Regular physical exercise to weightreduction, increased cardiovascular fitness,and physical working capacity.
![Page 41: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/41.jpg)
3.Pharmacological therapy :
![Page 42: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/42.jpg)
Anti-AGE Therapies
• It include Aminoguanidine, ALT-946, ALT 711, Statins (Cervistatin)
• Pyridoxamine, the natural form of vitamin B6, is effective at inhibiting AGEs at 3 different levels.– prevents the degradation of protein-Amadori
intermediates to protein-AGE products.
– In diabetic rats, pyridoxamine reduces hyperlipidemiaand prevents AGE formation.
– scavenges the carbonyl byproducts of glucose and lipid degradation
– Benfotiamine, a lipid-soluble thiamine derivative, inhibits the AGE formation pathway.
![Page 43: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/43.jpg)
DENTAL THERAPY CONSIDERATIONS• Patients with well-controlled diabetes can often be treated in
a similar way to non-diabetic patients.
• Communicate with patient’s physician to obtain control of blood glucose levels
• Control acute infections.
• As aggravated glycemic control increases the risk of micro & macrovascular diabetic complications like- Stroke, MI, Heart Failure.
![Page 44: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/44.jpg)
Timing of treatment
Patients with well controlled DM can be treated similarly to non-diabetic patients for most routine dental needs.
• Keep appointments short, atraumatic, and stress-free
• morning appointments
• Use appropriate vasoconstrictor agents
• For stressful procedures the usual drug regime may be altered
![Page 45: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/45.jpg)
ANTIBIOTICS USE
• Antibiotics are not necessory for routine procedures in patients with well-controlled diabetes.
• But considered in the presence of overt oral infection.
• The combination of mechanical debridement+ systemic tetracycline provide greater positive effect on glycemic control in some DM patients.
![Page 46: Diabetes mellitus & Periodontium](https://reader034.fdocuments.us/reader034/viewer/2022050704/559442c71a28abee2f8b4622/html5/thumbnails/46.jpg)
DENTAL IMPLANT CONSIDERATIONS IN THE DIABETIC PATIENT
• Diabetes-induced changes in bone formation:
• Inhibition of collagen matrix formation
• Alterations in protein synthesis
• Increased time for mineralization of osteoid
• Reduced bone turnover
• Decreased number of osteoblasts and osteoclasts
• Altered bone metabolism
• Reduction in osteocalcinproduction

Give 50 ml of 50% intravenous glucose- through a large vein to avoid thrombophlebitis.
As soon as patient recovers consciousness, start oral carbohydrate intake, otherwise 5-10% glucose infusion has
to be continued till patient recovers consciousness.
Intramuscular injection of 1.0 ml of glucagon may be given if hypoglycaemia is insulin induced. It promotes
glycogenolysis, gluconeogenesis.
If patient does not regain consciousness inspite of normal blood glucose levels, then cerebral oedema is likely possibility which should be treated with intravenous
dexamethasone or mannitol.

• A medical emergency from hyperglycemia is less
likely to occur in the dental office since it develops
more slowly than hypoglycaemia.

GUIDELINE- A[Suggested Guidelines for physicians and other medical health professions for Use in Diabetes
Practice]
• Patients with diabetes should be told that periodontal diseaserisk is increased by diabetes.
• If they suffer from periodontal disease, their glycaemic controlmay be more difficult, and they are at higher risk for diabeticcomplications such as cardiovascular and kidney disease.
• Patients with type 1, type 2 and gestational diabetes should
receive a thorough oral examination, which includes comprehensive periodontal examination.
• For all newly diagnosed type 1 and type 2 diabetes patients, subsequent periodontal examinations should occur & annual periodontal review is recommended.
• For children and adolescents diagnosed with diabetes, annual oral screening is recommended from the age of 6–7 years by referral to a dental professional.

GUIDELINE- B[Suggested guidelines for use in dental practice]
• If periodontitis is diagnosed, manage it properly. If not, patientswith diabetes should be placed on a preventive care regime andmonitored regularly for periodontal changes.
• Patients with diabetes presenting with any acute oral/periodontalinfections require prompt oral/ periodontal care.
• Patients with diabetes who have extensive tooth loss should beencouraged to pursue dental rehabilitation to restore adequatemastication for proper nutrition.
• Provide oral health education.
• Patients who present without a diabetes diagnosis, but at risk for type 2 diabetes and signs of periodontitis should be informed about their risk for having diabetes, assessed using a chair-side HbA1C test, and/or referred to a physician for appropriate diagnostic testing and follow-up care.

CONCLUSION• Diabetes mellitus has significant impact on tissues throughout the
body, including the oral cavity. As research indicates that poorlycontrolled diabetes increases the risk periodontitis.
• Alteration in host defence and tissue homeostasis appear to play amajor role.
• Advances in medical management of DM require a heightenedawareness by the periodontist in the various treatment regimensused by diabetic patients.
• Familiarity with various medications, monitoring equipments, anddevices used by diabetic patient allows provision of appropriateperiodontal therapy while minimizing the risk of complications.
