Tutorial One

Question 1

In a 6PPC what type of bleeding is recorded

Answer 1

bleeding from base of pocket

Question 2

modified bleeding score measures bleeding from where

Answer 2

marginal bleeding

Question 3

bleeding from pocket vs marginal bleeding

Answer 3

marginal - gives indication of patients OH
pocket - inflammation at base of perio pocket

Question 4

UNC15 probe

Answer 4

no ball
marking at each mm
black band at 4-5, 9-10 and 14-15mm

Question 5

PCP probe

Answer 5

(pocket charting probe)
no ball
black bands every 3mm

Question 6

BPE probe

Answer 6

0.5mm ball at end
black band 3.5-5.5

Question 7

probing force for BPE and pocket charts

Answer 7

20-25g

Question 8

most accurate probes for measuring furcation

Answer 8

Nabers furcation probe
(not used at GDH, instead UNC15 used)

Question 9

ideal and minimum length of time for re-evaluation after step 2

Answer 9

ideal is 3 months
minimum is 6 weeks
(gums will continue to heal for up to 12 months)

Question 10

what is meant by grade 1, 2 and 3 mobility

Answer 10

1 - 0.2-1mm horizontal
2 - 1-2mm horizontal
3 - >2mm horizontal and vertical (impinging on function)

Question 11

what is meant by grade 1,2 and 3 furcation involvement

Answer 11

1 - less than 1/3 involvement
2 - more than 1/3 but not through
3 - through and through involvement

Question 12

what does the HbA1c test tell us

Answer 12

measures glycated haemoglobin
gives indication of average blood glucose level in previous 8-12 week period

Question 13

what levels of HbA1c indicate
- good control
- increased risk of diabetes related complications

Answer 13

• good: between 48 and 58 mmol/mol (6.5-7.5%)
• risk: >58mmol/mol or >7.5%

Question 14

criteria for engaged periodontitis patient

Answer 14

improvement of >=50% in plaque and bleeding scores
plaque scores <=20% and bleeding scores <=30%
personal targets met

Question 15

what angle should probe be at when assessing marginal bleeding

Answer 15

45 degrees

Question 16

average pocket depth improvement after NSPD in 4-6mm pockets

Answer 16

1.5mm

Question 17

average pocket depth improvement in pockets >=7mm after NSPD

Answer 17

2.6mm

Question 18

if a resisdual pocket is not improving despite good operator technique, good OH and controlled risk factors, what could be the reasoning

Answer 18

anatomical features of tooth - enamel pearls, root grooves, vertical defects

Question 19

treatment option for ‘black triangles’

Answer 19

gingival veneer

Question 20

if treating an endo-perio lesion should endo or perio be treated first

Answer 20

endo

Question 21

how long after quitting smoking is it still a risk factor for periodontitis

Answer 21

7 years after quitting before risk factor lost

Question 22

discuss disclosing tablets

Answer 22

ideally used after brushing to identify areas of remaining plaque (contains vegetable dye)
chew or suck then swirl around mouth
pink colour shows new plaque
darker purple colour shows old plaque

Question 23

what line are the blue cavitrons from

Answer 23

power line
(good for heavier levels of calculus)
(3 different tips - one curve, 2 bends, 3 bends)

Question 24

what line are the green cavitron inserts from

Answer 24

thin line

Question 25

when would a straight ultrasonic tip be used

Answer 25

flat tooth anatomy

Question 26

when would a curved ultrasonic tip be used

Answer 26

furcations and concavities
