16
Q

Requirements of successful periodontal therapy (2)

A

Supragingival plaque control

Subgingival plaque control

17
Q

Effect of supragingival plaque control alone (4)

A

Decreased gingival inflammation
Limited effect on probing depth
No change in attachment levels
No alteration in subgingival microflora in deep pockets (>6mm)

18
Q

Effects of RSD without supragingival plaque control (3)

A

Initial reduction in inflammation and pocket depth
Pockets are re-colonised by bacteria from supragingival plaque
Disease recurs

19
Q

Effects of supragingival plaque control and RSD (4)

A

Decreased gingival inflammation
Reduction in probing depth
Gain in probing attachment
Marked changes in the subgingival microbial flora

20
Q

Decreased probing depth calculation

A

Gingival recession + gain in attachment level

21
Q

Gain in attachment is due to (2)

A

Long junctional epithelium formation

Improved tissue tone (inflammatory infiltrate is replaced by collagen)

22
Q

Effects of debridement (2)

A

Reduces microbial challenge (decreased inflammation)

Inoculation with plaque organisms (boosts immune response)

23
Q

Re-evaluation looks at the response to initial therapy (4)

A

Patient plaque control
BoP
Residual probing depths and attachment levels
Tooth mobility

24
Q

Measurements of periodontal treatment success (6)

A 
Good OH with no BoP
No pockets >4mm
Reduced probing depth
Gain in attachment
No change in furcation or tooth mobility
A functional and comfortable dentition
25
Q

Re-evaluation decision making (3)

A

Poor OH, persistent inflammation (supportive care or repeat CRT)
Good OH, inflammation resolved (supportive care and proceed with treatment plan)
Good OH, persistent deep pockets with BoP (surgical access or repeat RSD then re-evaluate)

26
Q

Reasons for treatment failure (3)

A

Poor compliance
Inadequate debridement
Host factors (smoking)

27
Q

Limitations of non-surgical therapy (5)

A 
Root morphology
Furcation involvement
Deep pockets
Skill level
Time
28
Q

Supportive periodontal care - management (4)

A

Maintain periodontal health
Detect and treat recurrence
Maintain an acceptable level of disease
Manage tooth loss
