TEST 2 Flashcards
3 things a clinician should be able to do to manage perio disease
Diagnose accurately
Predict effect of systemic status of disease
Confirm prediction with assessment of therapeutics
4 systemic factors that can modify gingival diseases
Endocrine system
Blood dyscrasias
Medications
Nutrition
Endocrine events that can cause gingivitis
Puberty
Menstruation
Pregnancy (gingivitis and pyogenic granuloma)
Diabetes
Blood dyscrasia that can cause gingival disease
How to limit severity
Leukemia (acute)
Reduce dental plaque
2 ways medications can modify gingival diseases
Gingival enlargement
Oral contraceptive gingivitis
Nutrition deficiency that can cause gingival disease
Ascorbic acid-deficiency
Clinical signs of chronic (adult) periodontitis
Pocket formation Loss of attachment Bleeding/suppuration Bone loss Tooth mobility and drifting
_ is a frequent finding in chronic perio
Subgingival calculus
Chronic perio is classified by _ and _
Extent and severity
3 common features of aggressive perio
Systemically healthy
Rapid attachment loss and bone destruction
Familial aggregation
Aggressive perio often has elevated levels of what two bacteria
A. a
P. Gingivalis
White cell abnormalities secondary to aggressive perio
Phagocyte abnormalities
Hyper-responsive macrophage (high PGE2 and IL-1B)
Localized aggressive periodontitis
Onset
Response to infecting agents
Presentation where?
Circumpubertal onset
Robust serum antibody response
Localized first molar/incisor presentation
Generalized aggressive perio usually affects who
People under 30
Serum antibody response in GAP vs. LAP
LAP - robust serum antibody response
GAP - poor response
In GAP, destruction of attachment and bone is _
Episodic
Periodontitis is associated with what two types of disorders
Hematologic
Genetic
The two types of Necrotizing periodontal disease are
NUG - necrotizing ulcerative gingivitis
NUP - Necrotizing ulcerative periodontitis
Clinical signs of NPD
Early
Advanced
Early - necrotic lesion on papilla first, then moving to gingival margin. Punched out appearance. Spontaneous bleeding.
Advanced - lack deep pockets, papillary and margin lesions merge, stinks, periodontal ligament and alveolar bone
NUP is typically seen in who
Severely immunocompromised people (HIV)
4 characteristics of periodontal health
Functional dentition
Painless function
Stability of periodontal apparatus
Psychological and social well being
5 values in assessing inflammation
Color Texture/edema Bleeding Exudate Plaque
Plaque index
Amount of plaque at gingival margin
PSR:
Purpose
Benefits
Limitations
Perio screening and recording
Rapid and effective way to screen and summarizes necessary info
Early detection, speed, simple, cheap, risk management
Not the same as a comp. perio exam, adults only
How to tell if a diagnostic test is valid
Sensitive
Specific
3 categories of diagnostic methods for Perio Diseases, and examples
- Clinical examination
- inflammation, probe depth - Lab tests
- biochemistry, genetic analysis - Non-invasive tools
- NIR, OCT, ultrasound
CBCT
What is it
Promising in what areas
Cone beam computed tomography
Intrabony defects Dehiscence Fenestration defects Periodontal cysts Furcation defects Thickness of palatal mucosa
Sensitivity vs. specificity
Probability the test is positive when disease is present
Spec - probability test being negative when disease is not present
Micro testing:
Sensitivity
Low
Immunodiagnostic methods are used mainly to detect
Aa and Pg
3 types of immunodiagnostic methods
Cytofluorography
ELISA
Latex agglutination
Several pathogens like Pg, Tf, and Aa have a ___ that hydrolyzes ___
Trypsin like enzyme
BANA
3 molecular biology techniques
Nucleic acid probes
Checkerboard DNA-DNA hybridization
PCR (real time too)
PCR sensitivity and specificity
High
High
_ components of GCF have been evaluated
3 main things
65
Host enzymes and inhibitors
Tissue breakdown byproducts
Inflammatory and host response mediators
Intracellular destruction enzymes
What?
Come from?
Examples of some
Markers of active perio destruction
From dead or dying PMN/neutrophils from perio
Aspartate amino-transferase
Alkaline phosphatase
B-glucuronidase
Elastase
Extracellular destruction enzymes are associated with activity of _
Come from _
Matrix metalloproteinases
Inflammatory, epith. And connective tissue cells
MMPs are secreted from
MMPs are responsible for _
Fibroblasts and macrophages
Remodeling and degradation of ECM components
ECM is composed mainly of what 3 things
Collagen
Proteoglycan
Non-collagen proteins
When collagen breaks down, _ is formed
Hydroxyproline
Tissue oxygen at periodontitis is _ compared to gingivitis and healthy sites
Significantly lower
What is SOBT, is it effective?
Salivary Occult Blood Test
Simple & for when thorough perio exam isn’t possible
Not a substitute
Bone loss % =
CEJ - Crest - 2 mm
__________________
CEJ - Apex - 2 mm
Mild vs. moderate vs. severe bone loss
Mild ≤ 20 < Moderate < 50 ≤ severe
Normal alveolar crest sits _
2mm below CEJ
T/F integrity of crestal lamina dura is related to the presence or absence of visual inflammation
FALSE
_ % of americans over 40 have perio disease
64
3 words that define Epidemiology
Origin
Spread
Pattern
Why use CPITN
Community perio index of treatment needs
Determine treatment patient needs
