27
Q

Why is bone loss in maxillary and mandibular anteriors more of a concern?

A

this is because they have the shortest roots and therefore are at an increased risk of mobility

28
Q

What clinical measurement is used to determine the stage of periodontal disease ?

A

Interproximal bone loss

29
Q

Staging is indicative of the _______ of the disease

A

severity

30
Q

Grading is indicative of the _________ of the disease

A

rate of progression of the disease

31
Q

What is stage I periodontitis ?

A

early/mild
15% bone loss
or <2mm attachment loss from CEJ

32
Q

What is stage II periodontitis?

A

bone loss ending at the coronal third of the root
moderate

33
Q

What is stage III periodontitis?

A

bone loss ending at the mid third of the root
severe

34
Q

What is stage IV periodontitis?

A

bone loss ending at the apical third of the root
very severe

35
Q

How is the grade of periodontal disease arrived at?

A

%bone loss / age
(%bone loss determined from the PA radiograph)

36
Q

What is grade A periodontal disease?

A

slowly progressing
<0.5

37
Q

What is grade B periodontal disease?

A

moderately progressing disease
0.5-1.0

38
Q

What is grade C periodontal disease?

A

rapidly progressing disease
>1.0

39
Q

Staging and grading of periodontal disease both require…

A

radiographs
using the worst site of bone loss to determine the periodontitis

40
Q

What does a baseline periodontal chart include?

A
  • 6PPC
  • recession
  • attachment loss
  • mobility scoring
  • furcation scoring
  • plaque scores
  • bleeding scores
  • suppuration
41
Q

What probes can be used to undertake a pocket chart?

A

UNC 15 (5, 10, 15)
Williams probe (1,2,3,5,7,8,9,10)- 4 and 6 missing

42
Q

Describe how a pocket chart should be undertaken

A

Walk the probe
record deepest pocket
record bleeding/suppuration if present

43
Q

6PPC are required to …

A

monitor the disease

44
Q

Describe the correct probing technique that should be used for the 6PPC

A
  • 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
Q

What area is especially important for probing?

A

the interproximal area; below the contact point - most difficult areas to clean

46
Q

How many instruments are used to assess mobility?

A

2 - usually the handle end

47
Q

What are the grades of mobility and what they indicate?

A
  • grade 0- normal movement 0.2mm
  • grade 1- <1mm movement horizontally
  • grade 2- >1mm movement horizontally
  • grade 3- horizontal and vertical movement
48
Q

How are furcations measured?

A

using a nabers probe

49
Q

What is a grade I furcation?

A
  • probe can enter <1/3 of the furcation width
50
Q

What is a grade II furcation?

A

nabers probe can enter >1/3 of the furcation width but not through and through

51
Q

What is a grade III furcation?

A

nabers probe can enter through and through

52
Q

Plaque scores are often taken following …

A

plaque disclosure

53
Q

What plaque scoring system is used on SOEL?

A

O’Leary

54
Q

In a plaque and bleeding score, what kind of bleeding is recorded?

A

marginal bleeding- moving probe swiftyly along the gingival margin

55
Q

What is the difference between bleeding on marginal probing and bleeding on probing?

A

marginal bleeding- moving probe swiftly along the margin

BoP- probe is put into the sulcus depth and bleeding recorded

56
Q

Give examples of risk factors that can be included in risk factor assessments

A

Suboptimally controlled diabetes
suboptimal oral hygiene
smoking
(other systemic health disease?)

57
Q

What is the most effective tooth brushing technique?

A

Modified bass technique

58
Q

What is the correct technique for interdental cleaning?

A
  • select correct size (snug)
  • insert under contact point
  • move back and forth
  • should be brushing gums and teeth
59
Q

What may happen to sizing of TePes with reduced inflammation?

A

TePe sizing may increase

60
Q

When should you advise patients to ID clean? What is the rational behind this?

A

Before they brush

After they brush, motivation to use TePes diminishes

61
Q

What additional cleaning aid is beneficial for patients with bridge work or patients with retainers and tight gaps?

A

Superfloss

62
Q

What is the aim of PMPR?

A
  • reduction in bacterial load
  • removal of plaque retentive factors
63
Q

Why must sub gingival instrumentation be under LA?

A
  • ensure effective clean- operator is able to go to a deeper depth to clear calculus whilst maintaining patient comfort
64
Q

How many visits should PMPR take?

A

As many as required to get a good clean

65
Q

What way can you split up appointments for PMPR?

A

2 visits- half mouth, half mouth
4 visits- quadrant by quadrant
