Q

what is BOP?

A

risk marker- best form of indicator of disease- however only 30% of sites go on to develop LOA- so essentially we are overtreating patients as we cannot determine which sites will progress and which sites wont.

Q

how do you carry out a bpe?

A
  • let the pt know the process and gain consent
  • walk the probe round the tooth and mark down the worst site within each sextant- must have at least 2 teeth in each sextant- if only 1 move to adjacent sextant

Q

what is code 4?

A
  • blank band no longer visible
  • ppd >5.5mm
20
Q

treatment for code 4

A

OHI
plaque and bleeding charts
6 point pocket charts
radiographs
RSD of sites greater than or equal to 4mm with bop or sites greater than 5mm
- review in 3 months with post op 6ppcs

21
Q

what does * mean

A

furcation involvement

22
Q

what is treatment for *

A

as for code 4

23
Q

what are the purpose of plaque and bleeding charts?

A
  • helps clinician and patient see where they are not cleaning well
  • can be used as a motivational tool
  • at review appointment new b and p charts can be used as comparison to assess if improvement or deterioration in OH.
24
Q

what do 6ppc tell us?

A
  • bop
  • ppds
  • FI
  • mobility
25
Q

what are the purpose of 6ppc ?

A
  • more detailed periodontal charts
  • indicate treatment required
  • motivational tool for patients
  • can be used to assess improvement or deterioration after treatment
26
Q

explain code 0,1,2 on british society of periodontology flow chat

A
  • <10% bop - CGH
  • 10-30% bop - localised ging
  • > 30% generalised gingivits
27
Q

what does code 3 pathway indicate?

A

no evidence of ID recession

  • may require radiographic assessment
  • initial therapy (PMPR and OHI) if pockets less than 4mm and no radiographic bone loss- follow 0,1,2
  • if pockets greater than or equal to 4mm and/or radiographic ev of bone loss- code 4 pathway
28
Q

code 4 pathway- pattern of disease

always 4 if radiographs and or ID recession

A

molar incisior pattern

affects <30% teeth- localised

affects >30% teeth- generalised

29
Q

staging of code 4

A

severity of disease- worst site of bone loss
stage 1- mild- less than 15% bone loss
stage 2- moderate- bone in the coronal 3rd of root
stage 3- severe- bone loss in the mid 3rd of root
stage 4- very severe- bones loss in the apical third of root

30
Q

grading code 4?

A

progression of disease
A- slowly progressing- <0.5
B- moderate progression- 0.5-1
C- rapid- >1

% bone loss/age

31
Q

assessment of periodontal status code 4-

A

stable- <10% bop, ppd < or equal to 4, no bleeding at sites of 4

in remission (partially responsive)- >10% BOP “”

unstable- bop at sites equal or greater than 4mm, sites >5mm

32
Q

what else is included in a periodontal diagnosis?

A

risk factors

33
Q

what is the gold standard RG for perio?

A

PA

34
Q

what other radiographs can be used?

A

vertical bws and DPT

35
Q

why are radiographs useful for periodontal diagnosis?

A
  • can assess extent of bone loss- pattern and amount
  • determine if theres interproximal calculus deposits
  • determine if there are overhangs or restoration deficiencies. -
  • determine if there is suggestion of furcations
36
Q

how do you assess mobility and what is its relevance?

A

using your finger and end of mirror or using 2 ends of mirrors
- can affect the prognosis of the tooth and affect function of the dentition.

37
Q

how do we measure mobility?

A

millers mobility index

38
Q

what does grade 0 mean for mobility?

A

movement of up to 0.2mm which is normal physiological movement

39
Q

what does grade 1 mean for mobility?

A

horizontal movement of more than 0.2mm but less than 1mm

40
Q

what does grade 2 mean for mobility?

A

horizontal movement of more than 1mm

41
Q

what does grade 3 mean for mobility ?

A

more than 1mm of horizontal movement or any vertical movement

42
Q

how do we measure furcation?

A

using hamps furcation classification and a periodontal or explorer probe

43
Q

explain hamps grading system?

A

grade 1- probe goes less than 1/3rd of the way through the furcation
grade 2- probe goes more than 1/3rd of the way through the furcation
grade 3- through-through- probe goes all the way through the furcation

44
Q

why is furcation involvement of relevance?

A

FI can affect the prognosis of the tooth:

furcation areas can have accessory canals meaning bacteria can enter the pulp via these canals- may lead to loss of vitality of the tooth

furcations are stagnation areas and are hard to maintain with at home oral hygiene practices and for the clinician to gain access and clean- controlling disease is made more difficult

45
Q

how can we treat furcations?

A

OHI- single tufted toothbrushes can be used for easier cleaning of these areas
furcationplasty
tunnel prep

both are used to widen the furcations in order for the patient to clean the area more effectively.

46
Q

what must you do for furcation involvment?

A

regrade- every 6 months
vitality test- every 1 year
