What separates the free gingiva and the attached gingiva?
This material helps hold cells together & provide framework to migrate/interact
Extracellular Matrix
Cementum
Test related to bacteria: Name, purpose, & considerations
Phase contrast: pt education; cannot detect specific
Culture & Sensitivity- determine sensitive antibiotic;difficulty in results
DNA- identify oral pathogens; only few identified
When there is a imbalance of good and bad bacteria this is?
Dysbiosis
Two main types of Cementum
Cellular-forms after, Cementocytes, 1/3 apical, deposition cementum
Acellular- forms before, covers 2/3 cervical, tooth support
What is the basal lamina function?
thin mat of extracellular fluid secreted by epithelial cells for support
3 Types of Cementum
Intermediate- in CEJ
Acellular(primary)- No living cells (mostly sharpy)
Cellular (cementum)-living cells present(less sharpy)
Horizonal crest contour vs. Vertical crest contour
H: CEJ of adjacent teeth same level
V: Adjacent teeth is tilted/erupt at different height
How do you control dsybiosis?
Interdental care, brushing, then mechanical removal by DH
Four anatomical areas of gingiva
Free gingiva, sulcus, interdental, attached
3 Different types of cells present in the gingival connective tissue?
Fibroblast, Mast cells,& Immune cells such as (machrophage, neutrophils, & lymphocytes)
2 Types of periodontal assessment
Periodontal screening exam (1st) "Baseline data"
Comprehensive (2nd)
If the probe depth measures 6 mm and the gingivial margin measures 2 mm apically from recession, clinical attachment loss is...
8
TRUE
PDL is anchored to both the _&_
Cementum and alveolar bone
What "rope like" protein fibers make up 55%-65% of gingival connective tissue?
Collagen fibers
List the Furcation Classifications
Class I- Detection of curve, no entry
Class II- Greater than 1mm, does not pass through
Class III- Pass through, no clinical visibility
Class IV- Pass through & Visible
What is the formula calculating plaque percentages?
# of the tooth surfaces with plaque divided by number of teeth present, multiplied by 100
Color, texture, consistency, contour, margin, bleeding
In health, the alveolar crest is loctated how many mm to the CEJ?
1- 2 mm
The principle fibers of the PDL are classified as...
Alveolar crest, horizontal, interradicular, oblique, & apical
PSR & CPI Sextant scores
CODE 0-1 Black band visible, Biofilm controlled
CODE 2-Black band but calculus present;remove calculus, correct restorations
CODE 3- 4/5mm Pockets band is partial, CPA & TX
CODE 4- 6mm Pockets band hidden CPA & TXTooth mobility scale rating is..
Class 1- slight mobile
Class 2- moderate, 1-2 mm horizontal displaced
Class 3- Severe; more than 2mm vertical displaced
Functions of PGE, MMP enzymes & RANK Mediators
PGE- MMP secretion
MMP- Breakdown collagen & periodontum
RANK- Recteptor of osteoclasts
