Clinical Attachment Loss (CAL) is calculated:
CAL = Pocket Depth (PD) + Free Gingival Margin (FGM)
The CAL can be indicated on the printed perio chart only when there is a PD and a FGM value recorded.
If only the PD is recorded yet the FGM is not recorded
- the FGM value will be blank
- the CAL value on the printed report will be 0 (zero)
If FGM is positive to indicate hyperplasia (indicated with a + sign):
- the FGM value is subtracted from the PD
Example #1 (tooth #4 in the screenshot):
PD = 2
FGM = 4
CAL = 6
Example #2 (tooth #6 in the screenshot):
PD = 3
FGM = +2
CAL = 1
Example #3 (all other teeth in the screenshot):
PD = 3
FGM = (blank value)
CAL = 0
