If you are right handed will you use a hatchet with a different angle cutting edge than someone who is left handed?

Here's are the choices from a practice exam:

13-87-9-15 or 13-83-9-15

Here is my input/guess

I don't think R versus L has anything to do with it. That number is more focused on whether or not its mesial (80) or distal (95) for a trimmer. Plus R and L handed people would sit on opposite sides of the patient so that should negate any differences in cutting edge angles --- it would just be like a mirror image I'm thinking.

I agree. Thank you.

Just remember that left-handed dentists have to buy burs with the cutting angles in the opposite direction, since they sit on the other side...

The assistants never remember to bring me the handpieces that spin the opposite direction. I think they're secretly conspiring to keep me from graduating.

Never knew that, that may explain a lot. Do the manufacturers label that informaiton on the packaging? We buy SS White Burs, and I have never seen that info.

I think a lot has changed since you started your residency. We now use AmbidexBurs that automatically adjust to operator handedness. You just have to make sure your handpiece is calibrated properly. Pretty cool stuff.

Wow! The guy that came up with that is driving a nice ride these days!

For a hatchet, it doesnt matter for righty or lefty. For a chisel, on the other hand, it makes a difference.

Brasseler does make lab burs that cut in the opposite direction for left-handers with the slow speed handpiece set for reverse.
