Q

How is diabetes related to periodontal disease?

A

Q

How are AGE and RAGE related to the periodontium by poorly / uncontrolled diabetes?

A

Excessive AGE modified proteins can be found in the oral cavity of a diabetic and interact with a cell receptor (RAGE) stimulating the release of proinflammatory cytokines. This can lead to exaggerated periodontal and systemic inflammation, insulin resistance and impaired tissue repair

24
How does hypertension affect the periodontium?
Impairs blood flow that supplies the periodonitum
25
Lifestyle modifications that should be suggested to improve the perdiontal risk of metabloic syndrome
Increase physical activity Practice good nutrition
26
Signs in the gingiva of leukemia-associated gingivitis
Swollen, glazed, spongy tissues Red to deep purple in colour Gingival enlargement
27
Why does inflammation of oral mucous membranes when undergoing chemotherapy?
Chemotherapy attacks and kills the rapidly dividing cells of the mucous membranes
28
Sloughing of the mucosa from oral mucositis can be
Localized or generalized
29
Reduced flow of saliva encourages growth of
Canadida albicans
30
Increased growth of Candida albicans causes
Oral candidasis
31
What should the dental hyienist look for in leukemia patients?
Spontaneous gingival bleeding and gingival enlargement for no apparent reason
32
Does chemotherapy cause a sore and sensitive mouth that bleeds easily?
Yes
33
How manage oral pain from oral mucositis
Topical anaesthetics have limited success Prophylactic use of chlorhexidine may reduce frequency of oral mucositis and oral pathogens
34
Periodontal and oral manifeatations of HIV infection
Hairy leukoplakia Candidiasis Herpes labialis Herpes zoster Recurrent aphthous ulcers Kaposi sarcoma Linear gingival erythema
35
Manifestations of HIV infection are known as
Linear gingival erythema
36
Linear gingival erythema is characterized by a
2 -3 mm marginal bane of intense redness in the free gingiva
37
Is linear gingival erythema assosciated with pocketing?
No
38
Does linear gingival erythema affect clinical attachment loss or alveolar bone levels?
No
39
Is it safe to perform periodontal therapy on an HIV infected individual?
Yes, as long as the immune system is competent
40
How is linear gingival erythema treated?
With standard periodontal procedures plus use of chlorhexidine gluconate
41
Increase in hormone levels causes in creased blood circulation to the gingival tissues and may cause increased sensitivity to local irritants such as plaque biofilm in this disease.
Pubertal gingivitis
42
What happens with pregnancy gingivitis?
Exaggerated response to small amounts of plaque due to increased estrogen levels and elevated progesterone levels.
43
What is a pyogenic granuloma?
Pregnancy tumour which is the papilla reacting strongly to plaque
44
What can be suggested for a pregnant client having frequent vomiting that is causing erosion?
Baking soda rinse
45
What happens during menopause and postmenopause to the periodontium?
Decreased levels of circulating hormones in result in oral changes: dry mouth burning sensation altered taste bone loss may worsen
46
What is the effect of gingiva called during menopause or postmenopause?
Menopausal gingivostomatitis
47
What are the characteristics of menopausal gingivostomatitis?
Gingiva bleed readily Abnormally pale Dry Shiny Erythematous
48
Does osteroporosis intitate periodontitis?
No
49
Can osteoporosis exacerbate the alveolar bone loss seen in preexisting periodonitits?
Yes
50
What can be recommended to menopause clients?
Calcium supplements Weight-bearing exercise Meticulous self-care
51
What are biphosphonates?
Most commonly prescribed medication to inhibit systemic bone resorption
52
Biphosphonates cause a rare disorder called
MRONJ
53
MRONJ is characterized by
Painful exposued bone in the mouth that fails to heal after extraction or oral surgery
54
Neutropenia is
Abnormally few number of neutrophils in blood
55
What does neutropenia lead to?
Increased susceptibilty for infection
56
PMN abnormalities can lead to
Overwhelming bacterial infection and severe periodontal destruction
57
Neutropenia is characterized by
The presence of abnormally few number of neutrophils in the blood which leads to increase susceptibilty to infection
58
Why do people with down syndrome have a higher risk of periodontal disease?
Abnormal PMN function in about 50% of people with down syndrome
59
How many medications have the potential to enlarge the gingiva?
20
60
What are the three major classes of drugs that can englarge the gingiva?
Anticonvulsants Immunosuppresives Calcium channel blockers
