Q

T/F: You can only give a GI score of 2 if it is bleeding.

A

FALSE

Bleeding always will give a score of 2.

But if inflammation is bad enough without bleeding can still give score of 2

Q

T/F: If one sextant is recorded as a three in PSR, the patient needs full mouth perio evaluation.

A

FALSE

3 on one sextant = perio eval that sextant

4 on one sextant or 3 on two sextants = full mouth perio eval
