|
Can you have plaque present and have healthy gums?
|
YES
|
|
|
Where is junctional epithelium attached?
|
at the CEJ
|
|
|
can you get variations of cementum?
|
Yes, loss of cementum developmentally or brushed away
|
|
|
What are the tissues like in healthy gingiva?
|
Plaque- none or limited G+ve aerobic
JE- normal attachment level Blood vessels/inflammatory cells- normal few neutrophil defence cells fibroblasts/collagen- normal Bone- normal Sulcus depth- normal Timeframe- Day 1+ |
|
|
in healthy bone where is crest of bone from CEJ?
|
1-2mm
|
|
|
What is normal sulcus depth?
|
0-3mm more than that indicates disease
|
|
|
What are tissues like in early gingivitis?
|
Plaque- G+ve aerobic
JE- lateral proliferation (sideways not downwards- growth) BV's/inflamm cells- increased permeability, neutrophils + few plasma cells Fibroblasts/collagen- some damage adjacent to JE Bone- normal Sulcus depth- normal Timeframe- 2-4 days |
|
|
Can children get perio?
|
Yes
|
|
|
What are the tissues like in established gingivitis?
|
Plaque- G+ve and G-ve
JE- lateral proliferation BV's/inflamm cells- increased permeability fluid accumulation in tissue, increased neutrophils, plasma cells, Ab's increased crevicular fluid Fibroblasts- increased damage adjacent to JE Bone- normal Sulcus- deepens Timeframe- 1week+ |
|
|
What are worse between G+ve and G-ve?
|
G-ve are more nasty in terms of peril as are anaerobic
|
|
|
Why may you see an increase in probing in established gingivitis?
|
due to inflammation as tissue balloon around it, reversible as no loss of attachment
|
|
|
What are the tissue changes in chronic periodontitis?
|
Plaque- G+ve and G-ve anaerobic, non adherent, motile
JE- apical proliferation BV's- increased permeability, increased neutrophils, plasma cells and macrophages, increased crevicular fluid suppuration Fibroblasts- increased damage apically Bone- loss Sulcus- deepens, true pockets recession Timeframe- months |
|
|
What is non-adherent plaque?
|
plaque on top of plaque in gingival crevice
|
|
|
What is apical proliferation?
|
no longer at CEJ somewhere down root of tooth, still attached but further down tooth
|
|
|
What is under JE?
|
periodontal ligament so destroys ligament
|
|
|
Can you tell loss of bone by looking?
|
NO, you have to probe
