Q

What is the appropriate management of a code III PSR

A
  • Comprehensive charting and exam of the affected sextant inbluding probing depths, mobility, gingival recession, mucogingival problems, furcation invasions, radiographs.
  • If 2+ sextants have a 3, full periodontal charting.

Q

When should you add an asterix to a PSR score

A

When findings of clinical abnormalities such as:

  • Furcation invasion
  • Mobility
  • Mucocgingival problems
  • Recession extending to the coloured area of probe 3.5mm or greater

Q

Are implants included in BPE?

A

No. The tissue connection and anatomical position often leads to deeper probing depths in healthy sites. Do 6 point probing and observe for bleeding or suppurtaion around each implant.

16
Q

How is adult BPE different to children/adolescents?

A

Child/Adolescent BPE involves assessing six index teeth: UR6, UR1, UL6, LL6, LL1, LR6

17
Q

What BPE scores should radiographs be obtained for?

A

Anything over a 3.

18
Q

Why are radiographs useful for perio assessment?

A
  1. Aid diagnosis and prognosis
  2. Permit assessment of morphology
  3. Assess petern of alveolar bone loss and monitor stability
  4. Provide info on other pathologies to guide overall prognosis
19
Q

Why is it important to use a beam aiming device for PAs to assess perio?

A

To avoid distortion of bone levels in relation to CEJ and the root length.

PAs are the gold standard for perio assessment.

20
Q

List 5 periodontal features which should be assessed and reported on a radiograph

A
  1. Degree of bone loss
  2. Pattern or type of bone loss
  3. Presenve of furcation defects
  4. Presence of subgingival calculus
  5. Other features eg perio-endo lesions, widered PDL spaces, abnormal root length or root morphology, overhanging restorations
21
Q

What might you see on a radiograph that would suggest a complex tx need and consideration for referral

A
  • Multiple angular defects
  • Furcation involvement
22
Q
A
23
Q

What is clinical attachment loss?

A

CAL is recession + probing depth

24
Q

When would a diagnosis of aggressive periodontitis be considered/

A

Where the plaque is inconsistent with the amount of attachment loss

25
Q

Does mobility increase or decrease after cleaning?

A

Should increase with CT reconnection unles there is some sort of issue with occlusion etc

26
Q

What is supportive periodontal therapy

A

Surveillance and monitoring of stable periodontitis patients

27
Q
A
28
Q

What is observed clinically to diagnose gingivitis?

A

BoP in more than 10% of sites

29
Q

What usually takes a diagnosis from gingivitis to periodontitis?

A

PD (CAL) over 4mm (in at least two non-adjacent teeth)

30
Q

What is the difference betwen the clinical crown and anatomic crown?

A

Clincail = what you see

Anatomic = incisal to CEJ

31
Q
A
32
Q

Which classifies the severity and extent of an individual based on currently measurable extent of destroyed and damaged tissue?

a) Staging
b) Grading

A

a) staging

33
Q

Which estimates future risk of periodontitis progresion and responsiveness to standard therapeutic principles

a) staging
b) grading

A

b) grading

34
Q

What is the ideal endpoint of non-surgical perio therapy

A

No pockeds with BOP greater than 4mm
