handpiece safety

Question 1

what is the safety protocol before use?

Answer 1

check the device’s integrity & performance

Question 2

what is the safety protocol during use?

Answer 2

recognise changes in device behaviour
-noise changes, vibrations, heating, intermittent performance
take appropriate remedial action if required
-report faults, change device

Question 3

what is included in a visual inspection?

Answer 3

expiry date on sterilisation pouch
obvious faults
-dents in device head
-damaged surface of optical rod

Question 4

what are the 6 safety checks?

Answer 4

1. check backcap secure
2. check bur secure
3. check device fits securely to coupling
4. check bur spins freely
5. check bur’s lateral movement
6. check sound produced in consistent

Question 5

how is the backcap checked? (1)

Answer 5

ensure the backcap cannot rotate
pinch outer rim of device head and apply rotational force
if can be rotated send for repair

Question 6

how is the bur checked? (2)

Answer 6

pull to ensure fully engaged

apply significant tension

Question 7

how to check coupling? (3)

Answer 7

fit handpiece to coupling

apply tension to ensure device secured

Question 8

why do you need to check bur spins freely? (4)

Answer 8

frictional resistance between components may cause overheating during use

Question 9

why do you need to check lateral movement? (5)

Answer 9

too much deflection will cause bur to wobble when activated, compromising control and cutting performance

Question 10

how do you check handpiece performance? (6)

Answer 10

run device for 5 sec

ensure it sounds right and bur doesn’t wobble

Question 11

when should handpiece safety protocol be done?

Answer 11

for each device used

in instinctive, seamless, repeatable way

Question 12

what should you do if you suspect a fault?

Answer 12

inform a dental nurse who will complete a dental handpiece fault report
