Handbook Flashcards
What is the stage of periodontitis a measure of?
Disease severity- and is assessed by the amount of bone loss (as a percentage of root length) at the worst affected site
What is the grade of periodontitis a measure of?
Measure of susceptibility and speed of progression
Calculated using the patients age and amount of bone loss
What is the name of the toothbrushing technique that is recommended?
Modified bass technique
Describe the modified bass technique.
Methodical approach
The toothbrush should be used at approximately a 45 degree angle to the tooth surface pointing towards the gum, half of the brush on the tooth and half on the gum.
Then use small back and forth strokes on no more than 2 teeth at a time
What is the fixed reference point for 6PPC?
Amelo-Cemental Junction (ACJ)
How do you calculate loss of attachment?
Adding probing depth and the gingival margin together
What is grade 1 tooth mobility?
<1mm of movement
What is grade 2 tooth mobility?
1-2mm of movement
What is grade 3 mobility?
> 2mm movement and/or rotation or depression
What is grade 1 furcation involvement?
1/3 horizontal attachment loss in furcation
What is grade 2 furcation involvement?
2/3 horizontal attachment loss in furcation
What is grade 3 furcation involvement?
A through and through furcation involvement
What does a BPE score of 0 indicate?
No calculus/overhangs, no bleeding on probing
Pocket depth <3.5mm
What does a BPE score of 1 indicate?
No calculus/overhangs
Bleeding on probing
Pocket depth <3.5mm
What does a BPE score of 2 indicate?
Supra or subgingival calculus/overhangs
Pockets <3.5mm
What does a BPE score of 3 indicate?
Probing depth 3.5-5.5mm
What does a BPE score of 4 indicate?
Probing depth >5.5mm
What does currently stable mean in periodontal health?
BoP<10%
Pocket probing depth less than or equal to 4mm
No BoP at 4mm sites
What does currently in remission mean in periodontal health?
BoP >10%
Pocket probing depth less than or equal to 4mm
No BoP at 4mm sites
What does currently unstable mean in periodontal health?
Pocket probing depth more than or equal to 5mm
Or pocket probing depth more than or equal to 4mm but with BoP
What are 6 Ramfjord’s teeth?
16, 21, 24, 36, 41, 44
What type of bleeding does modified bleeding score measure?
MARGINAL BLEEDING rather than bleeding on probing from the base of the pocket
What does marginal bleeding reflect on?
How well the patient is able to carry out effective plaque control daily
What does bleeding from the base of the pocket indicate?
Disease activity and periodontal breakdown
