Probing sequence per tooth:1= Distobuccal/ Distolingual:
Point of insertion is at the distobuccal line angle. Take one step distal and begin noting deepest reading. Probe into the col area.
2= Buccal/ Lingual:
Without removing probe, (from the distal col), begin walking towards the DB line angle. Begin noting deepest reading from the DB line angel to the ML line angle
3= Mesiobuccal/ Mesiolingual:
Continue walking mesially- noting deepest reading from first step after the ML line angle.

Walking Stroke of the Probe:

The walking stroke of the probe is different than other instruments in that the instrument ‘bobs’ or hops within the sulcus. Other instruments use more of a pull stroke with heavier lateral pressure against the tooth

Angulation of the probe into the col area:
Notice terminal shank is no longer parallel to the long axis of the tooth

Pivoting on Fulcrum will allow for movement of the Probe Handle

How to Read the Probe:
Once you reach the base of the sulcus:
Observe where the Gingival Margin is on the probe
![Page 25: Periodontal Probing](https://reader036.fdocuments.net/reader036/viewer/2022070404/56813c33550346895da5b1fb/html5/thumbnails/25.jpg)
Reading the Probe (Cont’d):
Now- count down from the
top marking on the probe (10 mm reading)
to thelast marking that you actually see
So, in this case:
10, 9, 8, 7, 6, 5, 4, 3, 2
Not actually marked on the probe

Reading the Probe (Cont’d):
So, in this case:
2 mm.

Reading the Probe (Cont’d):
Here we count

Reading the Probe (Cont’d):Here we count down10,9,8,7,5 but the gingival margin is still lower~
Only a small space is visible. Since the gingival margin is between the 5 and the 4~
we use the last reading we could see~
So, 5 mm is the probe reading.
