Monitoring and periodontal indices Flashcards
1
Q
Whats the definition of screening
A
To find cases with disease within a population
2
Q
Whats the definition of monitoring
A
To follow up a patients disease progression after treatment
3
Q
What is periodontal indices
A
- A form of periodontal monitoring
- Screens for disease & helps grade the level to reach a diagnosis
- Used to monitor response to treatment
- Research tool in clinical trials, public health and epidemiology
4
Q
When do we assess the extent of the disease
A
- Before treatment baseline
- After completion of treatment
- At review visits
5
Q
What is plaque the key factor in
A
- The aetiology of gingivitis
- The aetiology of periodontitis
- The success or failure of periodontal treatment
6
Q
What does a plaque index do
A
- Gives overall % of plaque in the mouth
- Allows you to show the patient where the plaque is
- Allows tailored oral health information
7
Q
Describe the 6 point pocket chart
A
- Apply jelly on a cotton wool roll to patient’s lips
- Ask patient to chew on disclosing tablet
- Swish tablet around for 30 seconds
- Spit out and rinse gently once
- Record presence of plaque on plaque chart
8
Q
What does a plaque score give
A
- A low mark for clean teeth
- A high mark for plaque covered teeth
9
Q
What does a plaque free score give
A
- A high mark for clean teeth
- A low mark for plaque covered teeth
10
Q
How do you do a marginal bleeding index
A
- Insert PCP 10 probe into gingival sulcus mid-buccally
- Run the probe towards the mesial papilla
- Insert the probe mid-buccally again
- Run the probe towards the distal papilla
- Run the probe similarly on the palatal/lingual surface
11
Q
What does periodontal indices include
A
- Bleeding on probing + probing pocket depths
- Attachment levels
- Mobility index
- Furcation indices
- Supprication
12
Q
When is a site positive for BOP
A
If bleeding occurs with or shortly after probing
13
Q
Describe the probing pocket depth chart
A
- Insert PCP 10 probe to full pocket depth
- Read off pocket depths in mms
- Record on pocket depth chart
- 6 sites per tooth
14
Q
Describe the attachment levels
A
- Measure from CEJ to the base of the pocket
- Detection of subgingival reference point
15
Q
Where is recession measured from and to
A
- Measurement from gingival margin to CEJ, where gingival margin is apical to the CEJ
16
Q
Describe the different grades of the furcation involvement
A
- Grade 1 - horizontal bone loss of less 1/3rd width of tooth
- Grade 2 - horizontal bone loss of greater than 1/3rd width of tooth
- Grade 3 - horizontal through and through involvement
17
Q
How is mobility graded
A
- Grade 1 - 1mm horizontal movement
- Grade 2 - Over 1mm horizontal movement
- Grade 3 - Vertical movement
