double ended scaler, blade at 100 degrees to shank, buccal and lingual surfaces for stubborn calculus deposits

Question 9

Answer 11

9 o’clock

Question 12

Answer 13

25,000

Question 14

Question 15

why is an FMPC better than a BPE

Answer 15

BPE only gives score for deepest pocket in sextant, so you dont know if a patient has generalised periodontal disease or local

Answer 16

periodontal pocket charting probe 12mm. 2 black bands that denote 3mm increments for precise measurements

Question 17

Answer 17

score out all missing teeth, measure gingival margin level, mobility, furcation, bleeding on probing

Question 18

what does the FMPC allow you to do?

Answer 18

aids definitive diagnosis, assess scale of periodontal disease and plan treatment. gives baseline for assessing treatment outcome
