The cpcf file

Basics and header

Now that we went over tooth surface charting, lets go over periodontal charting.

Just like the cdcf file, we start with the line: “SpecVersion=1”. And also like the cdcf file, we denote each tooth by the American system followed by the “|” symbol and then will have periodontal attributes associated with each tooth.

Periodontal probing

After the keyword “probing”, six numbers are expected which are associated with the probing depths. Where the probing depths are located depends on the quadrant we are working in. The best way to remember the order is to look at the tooth from the occlusal position and “up” being towards the facial or bucal, then then work clockwise starting with the buccal side “left” and then all the way around.

Maxillary right quadrant: [buccal/facial distal] [buccal/facial center] [buccal/facial mesial] [lingual mesial] [lingual center] [lingual distal]
Maxillary left quadrant: [buccal/facial mesial] [buccal/facial center] [buccal/facial distal] [lingual distal] [lingual center] [lingual mesial]
Mandibular left quadrant: [buccal/facial distal] [buccal/facial center] [buccal/facial mesial] [lingual mesial] [lingual center] [lingual distal]
Mandibular right quadrant: [buccal/facial distal] [buccal/facial center] [buccal/facial mesial] [lingual mesial] [lingual center] [lingual distal]

For example, lets say we have the following line:

...
3| probing 2 2 3 3 3 4
...

This would mean for tooth #3, the distal buccal probing depth is 2mm, the center buccal probing depth is 2mm, the mesial buccal probing depth is 3mm, the mesial lingual probing depth is 3mm, the center lingual probing depth is 3mm, and the distal lingual probing depth is 4mm.

Periodontal recession

Recession works the same way as probing but with the keyword “recession”.  So, looking at the following example:

...
4| probing 3 3 3 2 2 2; recession 0 0 1 2 0 0
...

Tooth #4 has 1mm recession in the mesial buccal aspect and 2mm recession in the mesial lingual aspect and no recession anywhere else.

Bleeding

Bleeding starts off with they attribute keyword “bleeding” but then expects either a “b” or “-“. The “b” meaning bleeding was present and “-” meaning there was no bleeding present. In the following example:

...
5| probing 3 3 3 2 2 2; recession 0 0 1 2 0 0; bleeding b b b - - b
...

In this case, tooth #5 had bleeding all along the buccal aspect and the distal lingual aspect.

Mobility

Mobility applies for the whole tooth, so there is only one number expected (which is the grade) after the mobility keyword. For example:

...
12| probing 6 6 7 8 4 7; recession 2 2 1 2 3 2; mobility 2
...

Which means tooth #12 has a mobility of grade II.

Furcation

Just like mobility, furcation applies for the whole tooth. For example:

...
30| probing 6 6 7 8 4 7; recession 5 5 5 2 3 2; furcation 2
...

Which means that tooth #30 has furcation grade II.

Other keyword attributes

The following are just keyword attributes that do not expect any additional information

  • Keyword dehiscence for Dehiscence
  • Keyword fenestration for Fenestration

 

And that’s it!
