Clinical session 3

Question 1

What is the goal of non-surgical periodontal treatment

Answer 1

• to achieve signs of periodontal stability which are easy to sustain
• plaque scores of below 15%
• bleeding scores of below 10%
• probing depths of less than 4 mm

Question 2

what can give rise to false pocketing

Answer 2

Oedema or hyperplasia of the gingival tissues

Question 3

When recording a six point pocket chart which probe are you most likely to use?

a. Nabers Probe
b. PCP 12 Probe
c. CPITN Probe
d. BPE Probe

Answer 3

b. PCP12 probe

Question 4

You have recorded a six point pocket chart for a patient and you are planning to carry out root surface instrumentation. At which sites would you carry out subgingival instrumentation?

a. At sites ≥4 mm probing depth where there are no sub-gingival deposits are present with no bleeding on probing
b. At sites ≥5 mm probing depth where there are no sub-gingival deposits are present with no bleeding on probing
c. At sites ≥3 mm probing depth where sub-gingival deposits are present or which bleed on probing
d. At sites ≥4 mm probing depth where sub-gingival deposits are present or which bleed on probing
e. At sites ≥3 mm probing depth where there are no sub-gingival deposits are present with no bleeding on probing
f. At sites ≥5 mm probing depth where sub-gingival deposits are present or which bleed on probing

Answer 4

d.At sites ≥4 mm probing depth where sub-gingival deposits are present or which bleed on probing

Question 5

High risk of periodontitis?

Answer 5

Smoking - not much bleeding even though tissue is inflammed

Question 6

What is the goal for treatment

Answer 6

Goal of treatment to not see pockets more than 4mm

• Any deeper is anaerobic environment that patietns can’t control with just brushing as can’t clean with bristles
• 4mm or less is managable, switching patient into supporting phase

Question 7

why do we want to calculate loss of attachment

Answer 7

• Indicates periodontitis as gives measurement of true pocket (gingivitis can have false pocket because of the inflammation)
• Tells us about severity of disease

Question 8

why do we calculate mobility

Answer 8

• How functional are the teeth
• Prognosis of tooth isn’t good with grade 2 or 3
• If you want to regain attachment there can’t be any movement (splinting of teeth). Splints are additional plaque retentive factor, making things better and worse. They need to have very good OH.
