Q

+ value on 6PPC

A

Recession

17
Q

Work out LOA

A

Pocket depth + gingival margin

18
Q

What are the furcation grades

A

1 - up to 3mm horizontal attachment loss
2 - 3-6mm horizontal attachment loss
3 - through and through

19
Q

What are the mobility grades

A

1 - <1mm
2 - 1-2mm
3 - >2mm and/or rotations

20
Q

Explain to a patient what gingivitis is

A
  • Gingivitis is the term used to describe red, swollen and inflamed gums
  • They may bleed on brushing
  • Gingivitis is caused by plaque (white sticky material that is made up of leftover food + saliva mix)
  • If plaque is not removed effectively it leads to gum disease
  • With good OH and help from dentist gingivitis is reversible
  • If not controlled, it can lead to a more severe form of irreversible gum disease called Periodontitis
  • This causes irreversible destruction to the bone supporting teeth into place leading to bone loss
  • A gum pocket is created, which is an ideal environment for bacteria to continue growing down the tooth
  • We want to work to stabilise this condition preventing it getting any worse and limiting the amount of bone loss
21
Q

List signs of periodontitis

A

Bleeding gums
Swollen/tender gums
Bad breath
Unexplained tooth loss
Tooth sensitivity
Recession
Mobility
Gum abscesses

22
Q

List some risk factors to gum disease

A

Diabetes
Smoking
Stress
Diet
Obesity
Certain meds
CVD

23
Q

What are the tx options for gum disease

A
  1. Do nothing
    - Don’t recommend
    - Gum disease leading cause of tooth loss
    - W/O tx will just get worse, will worsen existing symptoms
  2. Periodontal tx
    - OHI - help to clean your teeth
    - PMPR - targeted cleaning where you will not be able to reach
    - Baseline charts/ can monitor your progress to look for signs of improvement and stabilisation
24
Q

What are the benefits of perio tx

A
  • Decreased risk of diabetes
  • Fresher mouth, pinker tighter gums
  • Teeth less wobbly
  • Bleeding should stop
  • Less discomfort
  • Keep teeth longer
  • Bad
25
Q

What are the side effects of tx

A

Short term discomfort after LA wears off
Gum recession
Sensitivity to hot/cold
Temp increase in mobility
Root caries
Gaps between teeth

26
Q

List the BSP guidelines

A

STEP 1
- Explain disease, RF’s, risks+benefits inc no tx
-OHI, removal of plaque retentive factors
- Smoking cessation
- PMPR

STEP 2
- Subgingival PMPR
- Reinforce OH
- Re-evaluate after 3mths

STEP 3
- Managing unstable sites
- Reinforce OHI
- Repeat sub for 4-5mm pockets
- Consider referral for unresponsive

STEP 4
- Stable
- Supportive perio care
- Reinforce OH + behavioural change
- Regular PMPR
- Recall within 3-12mths
