Question 12

Answer 12

impants

Question 13

what 4 stages does hygiene phase therapy involve

Answer 13

dental health education
OHI
scaling and RSD.
removal of plaque retention factors

Question 14

what does dental health education involve in HPT

Answer 14

educating ptx on behavioural changes needed to achieve plaque control
assess medical / social / dental history to identify any risk factors
modified plaque and bleeding scores can be used to assess ptx engagement

Question 15

ramfjords teeth

Answer 15

6 teeth used to give an accurate representation of the mouth rather than assessing full mouth
teeth = 16, 21, 24, 36, 41, 44

Question 16

modified plaque score

Answer 16

RJs teeth divided into 3 surfaces - interproximal, buccal , palatal/lingual
scores added and divided by 36* to give percentage
code 0 = no plaque visible even with probe
code 1 = plaque seen only with probe
code 2 = plaque visible without probe

Question 17

modified bleeding score

Answer 17

probe run gently around gingival sulcus - no probing
RJs teeth divided into 4 - mesial, distal, buccal, palatal/lingual
code 0 = no bleeding
code 1 = bleeding present
scores added and divided by 24* to give percentage
