Q

L77: What are the series of events in a tx plan?

A
  • Emergency care;
  • Disease control;
  • Re-evaluation;
  • (Surgery);
  • Re-construction;
  • Supportive care.
19
Q

L77: What defines periodontal disease?

A
  • Loss of attachment;
  • True pocket formation;
  • Colonisation on the root surface.
20
Q

L77: What treatments are involved in ‘disease control’?

A
  • Extraction of hopeless teeth;
  • HPT;
  • Caries management;
  • Endodontic therapy;
  • Provisional prostheses.
21
Q

L77: What treatments are involved in ‘HPT’?

A
  • Dental health education;
  • OHI;
  • Scaling and RSD;
  • Removal of other plaque retention factors, e.g. defective restoration margins;
  • Re-evaluation.
22
Q

L77: What is involved in dental health education?

A
  • Evaluate patients reasons for attendance, attitudes to health care, motivation etc.;
  • Explain the nature of disease using diagrams, photographs, models etc.;
  • Discuss findings of examination.
23
Q

L77: What is involved in oral hygiene instruction?

A
  • Toothbrushing: modified bass technique;
  • Interdental cleaning (floss and tape, interdental sticks, interdental brushes);
  • Disclosing tablets.
24
Q

L77: How should an interdental brush fit a patient?

A

Snuggly - should displace bristles but not snap the wire

[give patients 2 or 3 sizes to start]

25
L77: What is 'scaling'?
The removal of plaque and calculus from tooth surfaces
26
L77: What is RSD?
Debridement: The act of removing dead, contaminated or adherent tissue, or foreign material RSD: scaling
27
L77: Why do we stay away from the term 'root planing'?
Planing: the removal or contaminated cementum, leaving the root surface smooth and hard Suggests removing cementum (patients would experience sensitivity) and is not done
28
L77: What type of scaling instruments are there?
- Hand instruments; | - Powered instruments (ultrasonic and sonic, rotating and reciprocating)
29
L77: What is the main advantage of hand instruments over powered?
More tactile feedback on the root and when you reach the base of the pocket
30
L77: What are the advantages of powered scalers over hand scalers?
- Less likely to scratch/ damage the root surface; - Water coolant: cavitation and flushing effect; - Ultrasonic/ sonic tips may allow for easier access to furcations; - Faster and less demanding on operator.
31
L77: What are the disadvantages of powered scalers?
- Can cause damage in the wrong hands; - Produce aerosols; - Can leave rougher surfaces.
32
L77: What problems with restorations (caused by dentist) can result in plaque retentive factors on a tooth?
- Poor margins; - Poor contour; - Partial dentures: gingival coverage, direct trauma, uncontrolled loads.
33
L77: How is the success of periodontal therapy measured?
- Inflammation (BOP); - Reduction in probing depth; - Gain in probing attachment level.
34
L77: On measurement, what is a false pocket?
When pocket is coronal to ACJ, i.e. inflamed gingivae [see L77]
35
L77: What can manual probing measurements be influenced by?
- Resistance of the tissues; - Size, shape and tip diameter of the probe; - Site and angle of the probe insertion; - Pressure applied; - Presence of obstruction such as calculus; - Patient discomfort.
36
L77: Successful periodontal therapy requires both supra and sub gingival plaque control, why?
Sub: - Reduction in probing depth; - Gain in probing attachment level; - Marked changes in the sub gingival microbial flora. Supra: - Removal alongside sub gingival plaque reduces inflammation; - Prevents re-colonisation of subgingival pocket; - Prevents reoccurrence of disease process.
37
L77: What happens to the gingiva as they heal and probing depths decrease?
Gingival recession (alongside gain in attachment level) = decreased probing depth
38
L77: What are the benefits of a full mouth disinfection? (i.e. full mouth debridement, over same day, and use of chlorohexidine)
- Prevents treated pockets being re-colonised by intra oral translocation of bacteria; - Use of chlorohexidine for sub gingival irrigation, tongue brushing and mouth rinsing.
39
L77: What is involved in re-evaluation?
Initial response to therapy: - Patient plaque control; - BOP; - Residual probing depths (+ attachment levels); - Tooth mobility.
40
L77: What is considered successful HPT, when re-evaluating?
- Good OH; - No BOP; - No pockets >4mm; - No increasing tooth mobility; - A functional and comfortable dentition.
41
L77: If HPT is not considered successful at re-evaluation, what must be done next?
Source the cause (is it poor OH and why etc.) so you can figure out how to proceed
42
L77: Why can HPT tx fail?
- Poor compliance; - Inadequate debridement; - Host factors (often smoking).
43
L77: What are the limitations of NST?
- Root morphology; - Furcation involvement; - Deep pockets; - Skill level; - Time.
