5-10% of all cases of diabetes and most often
occurs in children and young adults

are traditionally associated with diabetes,
including:

Type I and Type II Diabetes American Diabetes Association classification of diabetes mellitus
includes:
1. Type I diabetes (formerly known as insulin-
dependent diabetes):
a. Immune mediated
b. Idiopathic.
2.Type II diabetes
3.Gestational diabetes
4. Other types of diabetes:
(formerly known as noninsulin dependent diabetes)
Genetic defects associated with β-cell function and
insulin action.
b. Pancreatic diseases or injuries.
c. Infections.
d. Drug-induced or chemical-induced diabetes.
e. Endocrinopathies, e.g. acromegaly,
hyperthyroidism.
f. Other genetic syndromes
Bacterial Pathogens:
GCF glucose of diabetic patient is more then non-diabetic
 that is composed mainly of:
Capnocytophaga , anaerobic vibrios, Actinomyces species,
Porphyromonas gingivalis, Prevotella intermedia, and
Aggregatibacter actinomycetemcomitans
Aa , p.i, c.rectus ,p.m is more than others.

qualitative changes in
bacteria
contribute to the severity of periodontal
disease observed in those with poorly
controlled diabetes
Patients with type 1 diabetes mellitus and periodontitis have been
reported to have a subgingival flora
Polymorphonuclear Leukocyte Function
The increased susceptibility of patients with diabetes to infection has
been hypothesized as being caused by
• polymorphonuclear leukocyte (PMN) deficiencies
• impaired chemotaxis
• defective phagocytosis,
• impaired adherence
No alteration of immunoglobulin A (IgA), G (IgG),or M (IgM) has
been found in patients with diabetes

Altered Collagen Metabolism
Chronic hyperglycemia
• impairs collagen structure and function
• adversely affects the synthesis, maturation, and maintenance of collagen
and extracellular matrix
Sample Headline
patients with poorly controlled diabetes + increase in AGEs
The formation of AGEs (advanced glycation end products)occurs
• at normal glucose levels as well
• in hyperglycemic environments, AGE formation is
excessive
impact the integrity of the periodontium
Decreased collagen synthesis, osteoporosis, and a reduction
in alveolar bone height have been demonstrated in diabetic

STEP 5
Pronounced inflammation, edema, and gingival enlargement result from local factors that
might ordinarily elicit a comparatively mild gingival response
During the menstrual
period, the prevalence of
gingivitis increases
he accentuation of gingivitis during pregnancy occurs
has two peaks:
1. during the first trimester, when there is an
overproduction of gonadotropins,
2. during the third trimester, when estrogen and
progesterone levels are highest
when these drugs are taken for more than 1.5 years, there is an increase in periodontal
destruction
gingivitis is not a universal occurrence for all adolescents. With good oral hygiene, it can be prevented
Fissuring occurs in the mucobuccal fold, dry, burning sensation throughout the oral cavity
abnormal taste sensations, difficulty with removable partial prostheses.
signs and symptoms of menopausal gingivostomatitis aresomewhat comparable with those of chronic
desquamative gingivitis
Pregnancy
• 50-100 gingivitis - caused by bacterial plaque
• Tooth mobility, pocket depth, and gingival fluid
are also increased during pregnancy
• Onset (2 / 3 month) sever at (8month)
• Pronounced ease of bleeding is the most striking
inflamed and varies in color from bright red to bluish red
The marginal and interdental gingivae are edematous;
they pit on pressure
appear smooth and shiny, are soft and pliable, and
sometimes have a raspberry-like appearance.
the inflamed gingiva forms discrete “tumorlike” masses
P. intermedia appears to be the only micro-organism that
increases significantly during pregnancy

Purpura
Agammaglobulinemia, or
hypogammaglobulinemia
Leukocyte (Neutrophil) Disorders
• Neutropenia.
• Agranulocytosis. associated with a more generalized periodontal destruction that affects all teeth.
Neutropenia: low levels of circulating neutrophils
Chronic , cyclic / sever , benign
It affects as many as one in three patients who are receiving chemotherapy for cancer
who are receiving chemotherapy for cancer.
• absolute neutrophil count (ANC) of 1000 to 1500 cells/μL is diagnostic for mild neutropenia.
• ANC of 500 to 1000 cells/μL is considered moderate neutropenia
• ANC of less than 500 cells/μL Indicates a severe neutropenia
INSTRUCTIONS
defined as an ANC of less than 100 cells/μL
• Drug idiosyncrasy is the most common cause of agranulocytosis
• aminopyrine, barbiturates and their derivatives, benzene ring derivatives,
sulfonamides, gold salts, and arsenical agents
Characteristic:
• fever, malaise, general weakness, and sore throat.
• Ulceration in the oral cavity
• The mucosa exhibits isolated necrotic patches that are black and gray
Agranulocytosis is a more severe neutropenia that involves not only neutrophils
but also basophils and eosinophils
It may be chronic or periodic, with recurring neutropenic cycles
(e.g., cyclic neutropenia). generally occurs as an acute disease
Gingival hemorrhage, necrosis, increased salivation, and fetid odor
are accompanying clinical features.
generalized aggressive periodontitis has been described in patients
with cyclic neutropenia

  • 13. Polymorphonuclear Leukocyte Function The increased susceptibility of patients with diabetes to infection has been hypothesized as being caused by • polymorphonuclear leukocyte (PMN) deficiencies • impaired chemotaxis • defective phagocytosis, • impaired adherence No alteration of immunoglobulin A (IgA), G (IgG),or M (IgM) has been found in patients with diabetes

With good oral hygiene, it can be prevented Fissuring occurs in the mucobuccal fold, dry, burning sensation throughout the oral cavity abnormal taste sensations, difficulty with removable partial prostheses. signs and symptoms of menopausal gingivostomatitis aresomewhat comparable with those of chronic desquamative gingivitis
