Q

What are some limitations of conventional periodontal diagnostic techniques?

A
  • date respresents a disease/health evaluation at one point in time
  • clinicians need to attempt to identify, quantify and determine the extent, severity and relevance of both current clinical signs of inflammation as well as historical evidence of damage
  • sites of active disease can not be reliably identified or progression accurately predicted

Q

What do the ideal perio diagnostic tools provide?

A
  • all causes of the condition or differences in client susceptibility to disease
  • clear information on whether the infection is progressing or in remission
  • whether response to treatment will be positive or negative

Keep in mind that the current view of the natural history of disease susceptibility is related to the entire person vs just the local site (host response is largely generalized)

Q

What is the difference between pocket depth and CAL?

A

Pocket depth:

  • Distance between base of pocket and margin
  • May change due to changes in the position of the margin and migration of JE (margin and JE are not fixed points)

CAL

  • Distance between base of pocket and CEJ
  • Changes in LOA can result form gain or loss of attachment
  • Because one of the measurements is from a fixed point, CAL provides better indication of the amount and/or progression of attachment loss

Q

Briefly describe the methods and limitation in determining whether there is disease activity (active vs. inactive lesion)

A
  • No current accurate method to determine activity or inactivity of a lesion – only indicators of risk
  • Difference in CAL will show there has been disease activity but it is not predictive of further loss “isolated data”
  • Lesions show signs of inflammation are at high risk for further breakdown

Q

What are the most important clinical indicators of active disease?

A

bleeding and redness

though healthy sites can bleed and bleeding can be masked in heavy smokers

22
Q

Is there a sure method for determining whether a perio lesion is active?

A

no

-healthy sites can bleed and bleeding may be masked in heavy smokers

23
Q

How do we, then assess whether the disease is progressing and causing breakdown of perio tissues?

A

disease progression is tracked by clinical attachment levels and identifying LOA after the fact

threshold to rule out error is an increase in LOA of 2mm adn we can only make judgments based on risk factors

24
Q

Define risk assessment

A
  • Probability that an individual will develop disease within a given period
  • involves identification of risk factors
25
Q

Define risk factors

A

DW “attributes or exposures that significantly increase the risk for onset and/or progression of a specific disease & affect treatment outcomes”

C “characteristics of an individual that place them at increased risk for having a disease”

26
Q

Define risk factors

A

DW “attributes or exposures that significantly increase the risk for onset and/or progression of a specific disease & affect treatment outcomes”

C “characteristics of an individual that place them at increased risk for having a disease”

The number and type of risk factors a client has will modulate the onset, severity and progression of periodontitis

27
Q

Define risk indicator

A

risk factors that have been identified in x-sectional studies but not confirmed through longitudinal studies

HIV/AIDS

28
Q

Define risk predictors

A

associated with increased risk but not cause disease

BOP, medications

29
Q

Define risk predictors

A

associated with increased risk but not cause disease

BOP, medications

30
Q

How are risk factors categorized?

A
  • modifiable

- non-modifiable

31
Q

What are some modifiable risk factors?

A
  • smoking
  • diabetes
  • specific bacterial pathogens/poor OHI
  • osteoporosis
  • HIV/AIDS
  • stress
  • BOP
  • medications
  • local factors
32
Q

What are some non-modifiable risk factors?

A
  • history of perio
  • age (not a risk factor for perio disease)
  • gender
  • race
  • genetic disorders
  • genetic markers
33
Q

Briefly describe the parameters of risk factors (what can be included or considered a risk factor)

A
  • May be environmental, behavioral, or biologic factors increase the likelihood of disease
  • Are part of the causal chain and directly related to disease occurrence
  • Are identified through longitudinal studies of patients with the disease
  • Exposure to RF may be singular or multiple over a long period of time
  • Removal/reduction of RF should decrease risk
  • Must be present prior to the onset of disease
34
Q

What is the relevance of risk factors to DH care?

A

clinicians may use information:

  • to predict which clients are at risk for disease
  • aid in diagnosis
  • prevent disease by including interventions that decrease risk
35
Q

Expand on the relevance of risk factors to perio assessment and the process of DH Care

A
  • Assessment & analysis of RF provides info about susceptibility beyond traditional clinical assessment parameters
  • # & type of RF present modulate onset, degree & severity of disease
  • RF are important b/c conditions assoc. with increased risk may affect Tx, client management and outcomes
36
Q

What client information forms the basis for a risk factor assessment?

A

Interviews, MH, DH and clinical & radiographic examination

Based on current knowledge – therefore may change

37
Q

Which risk factors are considered the most significant?

A
  • Diabetes
  • Smoking
  • Pathogenic microbes
  • Genetic marker for IL-1
38
Q

What is the relevance of smoking in perio disease?

A
  • Direct relationship
  • Surgical & non-surgical therapy is less effective
  • Recurrence more common
  • Earlier onset of disease
  • Altered host response & direct local damage: decreased antibodies, impaired neutrophil function
  • Fibrotic gingiva, decreased bleeding (less O2)
  • Impaired healing related to decreased blood flow
39
Q

What is the relevance of diabetes in perio disease?

A
  • Strong RF when blood glucose is poorly controlled
  • increase susceptibility linked to immune dysfunction; impaired neutrophil chemostaxis & phagocytosis
  • Decreased/altered collagen metabolism, altered bone metabolism
  • Poor wound healing due to altered production of fibroblasts
  • Increased production of pro-inflammatory cytokines
40
Q

What is the significance of specific bacterial pathogens, poor OHI and local factors on perio disease?

A
  • A.a., P.g., T. forsythia, T. denticola cause direct tissue damage via enzymes & toxins as well as triggered an unregulated immune response
  • Presence of above in biofilm no guarantee that disease will occur – need other host and environmental factors
  • Good OH greatly decreases risk
  • Anatomical features of teeth may predispose to plaque accumulation
41
Q

What is the significance of osteoporosis on perio disease?

A
  • Assoc. between osteoporosis and alveolar bone loss
  • Estrogen deficiency has also been linked to decreased alveolar bone density
  • Extremely high risk for osteoporetic women who smoke
  • Not confirmed as true RF
42
Q

What is the significance of HIV/AIDS with perio disease?

A
  • Suspected risk indicator for p.d.
  • Linear gingival erythema may be present
  • Disproportionate amount of plaque compared with degree of inflammation
  • 3-17% have necrotizing ulcerating periodontitis (severe, rapid destruction)
43
Q

What is the significance of stress with perio disease?

A
  • Associated with depression of immune system

- Financial stress in adults with poor coping skills is a risk indicator for more severe perio disease

44
Q

What is the significance of BOP with perio disease?

A
  • Minimal value alone as a predictor of periodontal disease but in combination with increasing pocket depths, it does increase risk for continued destruction
  • Cessation of bleeding correlates with decreased gingival inflammation, repair of CT and pocket reduction
45
Q

What is the significance of medications with perio disease?

A
  • xerostomia

- enlargement

46
Q

What is the significance of genetic markers & factors and perio disease?

A

-Familial aggregation seen in aggressive p.d.
-Interleukin-1 (a key regulator in inflam. process and in increased #’s causes tissue destruction) is assoc. with severe chronic p.d.
(30% of Caucasians test +)
-PST can identify high risk clients and therefore the need for more aggressive tx.
-Test is prognostic versus diagnostic and is not as important as smoking or diabetes when evaluating risk

47
Q

What is the significance of history or periodontitis in perio disease?

A

puts individual at greater risk

48
Q

What is the significance of age in perio disease

A

assoc. with increased susceptibility not from aging itself but from the cumulative effects of periodontal breakdown over a lifetime

49
Q

What is the significance of gender and race in perio disease?

A

male, A. American may increase risk but SES may be more of factor than race

50
Q

What are four cardinal signs of periodontal health??

A
  1. A functional dentition
  2. The painless functioning of the dentition
  3. The stability of the periodontal attachment apparatus
  4. The psychological and social well-being of the individual
51
Q

How is the paradigm shifting when defining periodontal health?

A

-Suggest a more pragmatic approach is to focus on what is necessary to maintain periodontal health instead of focusing on disease
-Present definition may have meaning for dental health professionals but less so for clients
-Gingivitis is endemic and its clinical significance is as a disease is questionable
