26
Bone loss/CAL in >30% of teeth is indicative of …
generalised periodontitis
27
Why is bone loss in maxillary and mandibular anteriors more of a concern?
this is because they have the shortest roots and therefore are at an increased risk of mobility
28
What clinical measurement is used to determine the stage of periodontal disease ?
Interproximal bone loss
29
Staging is indicative of the _______ of the disease
severity
30
Grading is indicative of the _________ of the disease
rate of progression of the disease
31
What is stage I periodontitis ?
early/mild 15% bone loss or <2mm attachment loss from CEJ
32
What is stage II periodontitis?
bone loss ending at the coronal third of the root moderate
33
What is stage III periodontitis?
bone loss ending at the mid third of the root severe
34
What is stage IV periodontitis?
bone loss ending at the apical third of the root very severe
35
How is the grade of periodontal disease arrived at?
%bone loss / age (%bone loss determined from the PA radiograph)
36
What is grade A periodontal disease?
slowly progressing <0.5
37
What is grade B periodontal disease?
moderately progressing disease 0.5-1.0
38
What is grade C periodontal disease?
rapidly progressing disease >1.0
39
Staging and grading of periodontal disease both require…
radiographs using the worst site of bone loss to determine the periodontitis
40
What does a baseline periodontal chart include?
* 6PPC * recession * attachment loss * mobility scoring * furcation scoring * plaque scores * bleeding scores * suppuration
41
What probes can be used to undertake a pocket chart?
UNC 15 (5, 10, 15) Williams probe (1,2,3,5,7,8,9,10)- 4 and 6 missing
42
Describe how a pocket chart should be undertaken
Walk the probe record deepest pocket record bleeding/suppuration if present
43
6PPC are required to ...
monitor the disease
44
Describe the correct probing technique that should be used for the 6PPC
* probing should done parallel to the long axis of the tooth * must be in the correct adaptation- the probe tip should always be in contact with the tooth surface
45
What area is especially important for probing?
the interproximal area; below the contact point - most difficult areas to clean
46
How many instruments are used to assess mobility?
2 - usually the handle end
47
What are the grades of mobility and what they indicate?
* grade 0- normal movement 0.2mm * grade 1- <1mm movement horizontally * grade 2- >1mm movement horizontally * grade 3- horizontal and vertical movement
48
How are furcations measured?
using a nabers probe
49
What is a grade I furcation?
* probe can enter <1/3 of the furcation width
50
What is a grade II furcation?
nabers probe can enter >1/3 of the furcation width but not through and through
51
What is a grade III furcation?
nabers probe can enter through and through
52
Plaque scores are often taken following …
plaque disclosure
53
What plaque scoring system is used on SOEL?
O'Leary
54
In a plaque and bleeding score, what kind of bleeding is recorded?
marginal bleeding- moving probe swiftyly along the gingival margin
55
What is the difference between bleeding on marginal probing and bleeding on probing?
marginal bleeding- moving probe swiftly along the margin BoP- probe is put into the sulcus depth and bleeding recorded
56
Give examples of risk factors that can be included in risk factor assessments
Suboptimally controlled diabetes suboptimal oral hygiene smoking (other systemic health disease?)
57
What is the most effective tooth brushing technique?
Modified bass technique
58
What is the correct technique for interdental cleaning?
* select correct size (snug) * insert under contact point * move back and forth * should be brushing gums and teeth
59
What may happen to sizing of TePes with reduced inflammation?
TePe sizing may increase
60
When should you advise patients to ID clean? What is the rational behind this?
Before they brush After they brush, motivation to use TePes diminishes
61
What additional cleaning aid is beneficial for patients with bridge work or patients with retainers and tight gaps?
Superfloss
62
What is the aim of PMPR?
* reduction in bacterial load * removal of plaque retentive factors
63
Why must sub gingival instrumentation be under LA?
* ensure effective clean- operator is able to go to a deeper depth to clear calculus whilst maintaining patient comfort
64
How many visits should PMPR take?
As many as required to get a good clean
65
What way can you split up appointments for PMPR?
2 visits- half mouth, half mouth 4 visits- quadrant by quadrant
