Q

Where should you calculate bone loss form (which site)

A

at the worst affected site (do not take an average, instead take stage from worst site)

Q

How do you give a patient a grade for periodontal disease

A
  • Fine the worst site of bone loss and assign it a percentage
  • Know patients age
  • Bone loss % / age

Q

What would a Grade A periodontal disease be

A
  • slow progression
  • <0.5 % bone loss/age
  • Bone loss is less than half the patients age

Q

What is the BSP guidelines of a patient who scores a BPE of 3

A
  • if a sextant scores 3, this sextant should be reviewed AFTER initial treatment and a 6 point pocket completed for that sextant only (and only after treatment)

Q

What is the SDCEP guidelines for a patient who scores a BPE of 3

A
  • if a sextant scores 3, a 6 point pocket chart should be completed for that sextant BEFORE and AFTER treatment. Full periodontal examination of all teeth and RSD where necessary.

Q

What is the definition of ‘Stage’

A

the stage of periodontitis is a measure of the disease severity and is assessed by the amount of bone loss (as a percentage of root length) at the worst affected site

17
Q

What is the definition of ‘grade’

A

Grade of periodontitis is a measure of susceptibility and speed of progression, and is calculated using the patients age and amount of bone loss

18
Q

How is disease stability assessed

A

By the presence of inflammation (bleeding on probing)
