pros

Question 1

lab prescription for primary imps stage

Answer 1

please pour casts in 100% dental stone and construct special trays
please include 3mm spacer and extra oral handle

Question 2

lab prescription for acrylic master imps

Answer 2

please pour casts in 100% dental stone and construct record blocks with shellac base upper and wire strengthener lower

Question 3

lab prescription for CoCr master imps

Answer 3

please pour casts in improved dental stone and construct framework trial per design

Question 4

reasons for temporary reline of denture

Answer 4

grossly ill fitting denture causing frictional growth e.g leaf fibroma
coe-comfort tissue conditioner

Question 5

reason for soft reline of denture

Answer 5

painful areas
- soft lining deteriorate quickly

Question 6

reasons for hard/ permanent relines

Answer 6

poor master imps, poor peripheral seal

Question 7

impression technique for reline/ rebase

Answer 7

• remove all undercuts from fitting surface
• imp taken of fitting surface using light body silicone
• ask pt to bite until set

Question 8

what is recorded on 6PPC

Answer 8

missing teeth
gingival margins
pocket depth
bleeding
furcations
mobility

Question 9

what things can we look at to help assess outcomes of perio treatment

Answer 9

• are they engaged , from MPBS
• Probing depths , ideally pockets less than/ equal to 4mm with no BOP at 4mm sites
• reduction in symptoms - bleeding when brushing, redness, swelling

Question 10

average amount of pocket closure seen after course of perio treatment

Answer 10

74%
(pocket that is 4mm or less with no BOP, was previously more than 4 or 4 with BOP)

Question 11

average amount of pocket depth reduction after a course of perio treatment

Answer 11

1.4mm

Question 12

what may impact periodontal treatment success

Answer 12

OHI - patient engagement and clinician coaching
systemic disease e.g diabetes control - can impair healing
smoker - can impair healing
effectiveness of instrumentation - technique, experience, root grooves, defects
- initial pocket depths

Question 13

what happens in periodontal healing

Answer 13

increase in collagen fibres in connective tissue below pocket
formation of long junctional epithelium attachments

should wait 6-12 weeks to evaluate step 2/3 to allow connective tissue time to heal

Question 14

what contributes to reduction in pockets

Answer 14

increased clinical attachment and recession

Question 15

how does diabetes contribute to perio

Answer 15

diabetes increases inflammation in periodontal tissues and sees increased deposition of AGEs
Results in activation of immune and inflammatory response and upregulation of cytokines that favour bone resorption

Question 16

how does perio contribute to diabetes

Answer 16

bacteria and inflammatory products from perio enter systemic circulation and contribute to upregulated systemic inflammatory response
