16
Q

what does necrotising gingivitis look like clinically

A

punched out interdental gingiva

17
Q

how do we classify periodontitis

A

extent stage grade stability and risk factors

18
Q

what are the stages

A

stage 1: initial
stage 2: moderate
stage 3:severe potential additional tooth loss
stage 4:potential loss of dentition

19
Q

HOW IS extent and distribution characterised

A

generalised
localised
molars/incisors

20
Q

what are the grades

A

grade A slow less than 0.5
grade B moderate 0.5-1.0
grade C rapid rate of progression greater than 1.0

21
Q

how do we write a diagnosis statement

A

extent- periodontitis-stage-grade-stability- risk factors

22
Q

what is the stage

A

extent of clinical attachment loss or bone loss

23
Q

what is the grade

A

to indicate the rate of progression,responsiveness to standard therapy and potential impact on systemic health

24
Q

what do we consider for the assessment of current perio status

A

currently stable
currently in remission
currently unstable

25
Q

what are the characteristics of current stable assessment of current perio status

A

BoP less than 10%
probing pocket depth- less than or equal to 4mm
No BoP at 4mm sites

26
Q

what are the characteristics of current in remission assessment of current perio status

A

BoP greater than or equal to 10%
PPD less than or equal to 4mm
no BoP at 4mm sites

27
Q

what are the characteristics of current unstable assessment of current perio status

A

PPD greater than or equal to 5mm or

greater than or equal to PPD and BoP

28
Q

how do we calculate grading

A

% bone loss divided by the age of the patient

29
Q

what will radiographs need to be reviewed to determine

A

distribution of extent
worst affected site for staging
percentage bone loss in relation to age for grading
