classification of disease extent of inflammation shape and dimensions of sulcus or pocket probing depths attachment level root surface irregularities location of calculus width of attached gingiva recession evaluate treatment |
|
|
what are the general design characteristics of the probe?
|
calibrated blunt/rounded working end may be circular or flat |
|
|
What is needed with proper use of the probe? |
grasp fulcrum mirror |
|
|
how many measurements per tooth? |
6 |
|
|
what measurement is recorded for each surface? |
deepest number |
|
|
what position should the probe be in in regards to the long axis and tooth? |
parallel and adapted |
|
|
what kind of stroke is used in probing?
|
walking |
|
|
how do you keep the probe adapted? |
roll it |
|
|
where do you enter with the probe? |
at the distal line angle |
|
|
what is the first measurement you should take? |
the COL measurement |
|
|
what is important to do when taking the COL measurement? |
walk probe to contact area and slightly angle it to the COL space |
|
|
What is the second measurement you should take? |
the deepest along the lingual or facial surface |
|
|
what is the 3rd measurement you should take? |
the mesial COL area |
|
|
how do you do the walking stroke?
|
bobbing up and down as it advances 1mm around the tooth |
|
|
what will happen if probing in an unhealthy area? |
it will bleed |
|
|
where does the probe touch in a diseased sulcus? |
the epithelium on the root below the CEJ |
|
|
what measurement is a healthy sulcus? |
1-3mm |
|
|
what measurement is an unhealthy sulcus? |
greater than 3mm |
|
|
what may occur in an unhealthy sulcus in regards to the bone? |
bone loss |
|
|
what is the sequence for the anterior teeth? |
left to right |
|
|
how is gingival recession measured? |
in mm from gingival margin to CEJ |
|
|
what happens if there is no attached gingiva? |
the probe will slide all the way down |
|
|
how do you calculate the width of the attached gingiva? |
subtract the probing depth from the width of the gingiva |
|
|
What does CAL stand for? |
calculated attachment level/loss |
|
|
what is CAL? |
measurements made from a fixed point (CEJ) that doesn't change so it provides a reliable indication of the extent of bone loss |
|
|
How many classes of furcations are there? |
4 |
|
|
what is class 1 furcation? |
can feel the furcation area with the probe but can not enter |
|
|
what is class II furcation? |
probe can partially enter furcation but can not pass completely through |
|
|
what is class III furcation? |
passes through furcation |
|
|
What is class IV furcation? |
same as 3 but you can visibly see it |
|
|
What are 2 techniques for measuring mobility? |
putting the end of 2 instruments on either side of the tooth pressing down on the tooth with the end of an instrument |
|
|
how many classes of mobility are there? |
3 |
|
|
what is class I mobility? |
slight mobility with up to 1 mm of horizontal displacement |
|
|
what is class II mobility? |
moderate mobility with 1-2mm of horizontal displacement |
|
|
what is class III mobility? |
severe mobility with 2mm of horizontal or vertical displacement |
|
|
how do you mark on the chart which points bled with probing? |
circle the number INSIDE the box |
|
|
what do you need to mark on the charting paper? |
furcations recession mobility NAG irregular tissue margins CAL |

|
what is PSR used for? |
community
humanitarian military triage |

what can affect the accuracy in probing? |
not holding the probe parallel to tooth |
|
|
how do you chart mobility? |
write the class number in the notations box in red |
