Answer 9

measure from CEJ

what does staging measure?

Answer 10

severity

Question 11

Answer 11

susceptibility/progression

Question 12

perio grade A

Answer 12

slow progression

<0.5 % bone loss/age (less than half px age)

perio grade B

Answer 13

moderate progression

0.5-1.0 bone loss/age

type (eg generalised)
stage, grade, status (eg stable)
risk factors

Question 17

what is the BPE

Answer 17

a screening tool to guide clinicians to arrive at a provisional diagnosis of periodontal health. no indication of attachment/bone loss

Question 18

what are the options on recording when a BPE sextant scores 3?

Answer 18

sextant reviewed after tx and 6 point chart for that sextant only
6 point for sextant before and after tx

how do you arrive at a diagnosis?

Answer 19

medical and dental hx

further investigations
