periodontal disease and systemic relationship Flashcards
periodontal disease associated disease
1) uncontrolled diabetes
2) Heart disease
periodontal disease is a chronic inflammatory disease
1) increase inflammatory mediators in circulation
2) periodontal pathogens can enter blood stream
- transient ischemia
- local inflammation
microbial challenge
gram - organisms
- anaerobes
- produce virulence factors
- gingipans (proteases)
host inflammatory response
1) IL2, IL6, IL8, TNF alpha
neutrophils, macrophages, lymphocytes
- CT and bone destructions
- MMP destroy collagen, gelatin, elastin
2) leads to periodontitis
pathogenesis of periodontal diseases
1) depends on genetic risk and environmental risk factors
systemic effects of periodontitis
1) CVD
2) pre term birth
3) diabetes
4) respiratory disease
5) alzheimer
atherosclerosis
1) a progressive disease loss of elasticity in medium and large arteries
2) infections and inflammation are associated with fatty plaques and thromboembolism
3) BP, smoking, and high cholesterol influence
c reactive protein
1) acute phase response CRP, fibrinogen
2) forms fatty plaques (promotes atherogenesis)
bacteremia
1) bacteria directly infect blood vessels
how is the mechanism being tested
1) antibody titers
2) systemic inflammation
3) oral microbiology
4) etc.
antibody titer
1) titers to certain perio pathogens linked to increased prevalence of CVD atherosclerosis in carotid
2) increased risk for cardiac events in 10 year follow up
systemic infections
1) CRP levels increased means there is a strong relationship with CV events
oral microbiology
1) periodontal pathogens are present in atherosclerotic plaques where they may play a role in the development and progression of atherosclerosis
intervention studies
1) intreating patients with severe perio, following acute systemic inflammation, there was an improvement of endothelial function
2) periodontal treatment decreases systemic inflammation
management of periodontal disease in high risk atherosclerosis patients
1) complete perio exam
2) prevention and treatment of perio
3) education
4) modify risk factors for atherosclerosis
pregnancy gingivitis
1) 30-75% of pregnant women
2) erythema
3) edema
4) hyperplasia
4) bleeding
pregnancy tumors
1) grow and bleed rapidly
2) hyperplasia
etiology
1) subgingival plaque and calculus
2) maternal hyperimmunoresponsiveness
3) hormones
preterm low birth weight
1) preterm
- before 9 mo of gestation
2_ low birth weight
- <5 lbs
biological plausibility
1) periodontal disease
2) inflammatory response
3) mediators
- PGE2 and TNFalpha
4) uterine contraction cervical dilation
periodontal disease and preterm birth
1) association has odds ratio of 7.9
2) strong association
3) treatment of periodontitis doesnt have much effect on preterm birth
- fail to show reducitons in pregnancy complications
management of pregnant patients
1) preventative oral services
2) if exam needs perio therapy, 2nd trimester
3) acute infection, abscess or other sources of sepsis my warrant prompt innervation
diabetes and periodontal disease
1) negative effect of glycemic metabolism
2) AGE produced *protein + fate +sugar)
2) accumulation of AGE influence perio destruction
3) alters collagen metabolism leading to unhealthy collagen breakdown and poor healing
4) AGE + RAGE increases proinflammatory cytokines
how does PD influence diabetes
1) chronic inflammation increases dysregulated inflamed environment, increases insulin resistance
2) anything greater than 7 is uncontrolled diabetes
