Q

Definition of Periodontal disease

A

A group of diseases affecting the periodontal tissues, representing an immune reaction (innate and adaptive) to adjacent microbial plaque. It is a multifactorial condition with complex etiopathogenesis.

Q

Definition of Periodontitis

A

Inflammation of the periodontal tissues, causing shrinking of gums and loosening of teeth. May progress at different rates at different sites in the mouth and in different people

Q

Why is Smoking a risk factor for Periodontal disease?

A
  • Has an effect on oral microbiota
  • Increase activation of the immune system
  • Decreased healing capacity due to reduced blood flow

Q

How does obesity have an affect on periodontal health?

A
  • Adipocytes secrete adipokines
  • Examples are leptin, Adiponectin and resistin
  • Have a proinflammatory effect and can lead to periodontal disease

Q

What drugs can be a risk factor for periodontal disease?

A
  • Anticonvulsant (Phenytoin)
  • Immunosupresants (Cyclosporin) e.g. transplant patients
  • Calcium channel blockers (Nifedipine, amlodipine)

Q

How can some drugs affect periodontal health?

A
  • Interaction between the drug and host fibroblasts
  • Result in increased deposition of connective tissue supporting a hyperproliferative (abnormally high rate of proliferation of cells by rapid division) epithelium
17
Q

What is gingival enlargement hyperplasia?

A
  • Abnormal overgrowth of gingival tissues
  • Caused by more fibroblasts
18
Q

What is gingival swelling?

A
  • Redness and inflammation of gingiva
  • More intercellular fluid increased permeability of the vessels (caused by some drugs)
19
Q

What is Chronic granulomatous disease?

A
  • Abnormal leucocyte intracellular killing
20
Q

How does HIV affect periodontal tissues?

A
  • Increased risk of necrotising conditions
  • No evidence of increased progression of periodontisis
21
Q

How does Blood dyscrasias e.g. Neutropenia, Agranulocytosis and Leukaemia affect periodontal tissues?

A
  • Reduced numbers/functions of neutrophils and macrophages
  • Increases risk of NUG (Necrotising ulcerative gingivitis) and progressive periodontitis
22
Q

How does pregnancy affect periodontal tissue?

A
  • Increased risk of gingival inflammation (pregnancy gingivitis)
23
Q

How does Osteoporosis and Osteopenia affect periodontal health?

A
  • Low bone mineral density in maxilla and mandible as a result of osteoporosis
  • Accelerates alveolar bone resorption in periodontal infection
24
Q

How does Psychological stress affect periodontal health?

A
  • In response to stressful events the hypothalamus-pituitary-adrenal axis is stimulated
  • Leads to increased production and secretion of cortisol
  • Cortisol can stimulate the immune system
  • ANS is also stimulated leading to secretion of catecholamine and substance P which regulates immume/inflammatory response and affect bacterial adherence and growth
25
Q

What are the Long term clinical complications of Hypertension?

A
  • Heart failure
  • Renal failure
  • Dementia/stroke
  • Vascular disease

Hypertension is main mortality reason among world population

26
Q

What is atherosclerosis?

A
  • Inflammation of the vessels wall
  • Clogged with fatty substances called atheroma
27
Q

What is preeclampsia?

A
  • Condition that causes high blood pressure during pregnancy and after labour
  • Can be serious if not treated
28
Q

How does untreated periodontitis affect Diabetes Mellitus patients?

A
  • Lead to circulating bacteria and bacterial antigens
  • Lead to elevated circulating levels IL-6, TNF-alpha, CRP, oxygen radicals
  • Both lead to systemic inflammatory state impaired insulin signalling and resistance
  • Lead to elevated HbA1c levels and exacerbation of diabetes
  • Increased diabetes complication
29
Q

How does ongoing periodontal treatment affect Diabetes Mellitus patients?

A
  • Reduced circulating bacteria and antigens
  • Reduced circulating TNF-alpah and CRP (C-reactive protein)
  • Reduction in systemic inflammatory state improvement in insulin signalling and resistance
  • Reduction in HbA1c and improved diabetes control
  • Less diabetes complications
