Tutorial One Flashcards
In a 6PPC what type of bleeding is recorded
bleeding from base of pocket
modified bleeding score measures bleeding from where
marginal bleeding
bleeding from pocket vs marginal bleeding
marginal - gives indication of patients OH
pocket - inflammation at base of perio pocket
UNC15 probe
no ball
marking at each mm
black band at 4-5, 9-10 and 14-15mm
PCP probe
(pocket charting probe)
no ball
black bands every 3mm
BPE probe
0.5mm ball at end
black band 3.5-5.5
probing force for BPE and pocket charts
20-25g
most accurate probes for measuring furcation
Nabers furcation probe
(not used at GDH, instead UNC15 used)
ideal and minimum length of time for re-evaluation after step 2
ideal is 3 months
minimum is 6 weeks
(gums will continue to heal for up to 12 months)
what is meant by grade 1, 2 and 3 mobility
1 - 0.2-1mm horizontal
2 - 1-2mm horizontal
3 - >2mm horizontal and vertical (impinging on function)
what is meant by grade 1,2 and 3 furcation involvement
1 - less than 1/3 involvement
2 - more than 1/3 but not through
3 - through and through involvement
what does the HbA1c test tell us
measures glycated haemoglobin
gives indication of average blood glucose level in previous 8-12 week period
what levels of HbA1c indicate
- good control
- increased risk of diabetes related complications
- good: between 48 and 58 mmol/mol (6.5-7.5%)
- risk: >58mmol/mol or >7.5%
criteria for engaged periodontitis patient
improvement of >=50% in plaque and bleeding scores
plaque scores <=20% and bleeding scores <=30%
personal targets met
what angle should probe be at when assessing marginal bleeding
45 degrees
average pocket depth improvement after NSPD in 4-6mm pockets
1.5mm
average pocket depth improvement in pockets >=7mm after NSPD
2.6mm
if a resisdual pocket is not improving despite good operator technique, good OH and controlled risk factors, what could be the reasoning
anatomical features of tooth - enamel pearls, root grooves, vertical defects
treatment option for ‘black triangles’
gingival veneer
if treating an endo-perio lesion should endo or perio be treated first
endo
how long after quitting smoking is it still a risk factor for periodontitis
7 years after quitting before risk factor lost
discuss disclosing tablets
ideally used after brushing to identify areas of remaining plaque (contains vegetable dye)
chew or suck then swirl around mouth
pink colour shows new plaque
darker purple colour shows old plaque
what line are the blue cavitrons from
power line
(good for heavier levels of calculus)
(3 different tips - one curve, 2 bends, 3 bends)
what line are the green cavitron inserts from
thin line
when would a straight ultrasonic tip be used
flat tooth anatomy
when would a curved ultrasonic tip be used
furcations and concavities
