4: Double Periodontal Pocket Charts Flashcards
2 types of periodontal probes?
- WHO/CPITN probe
- CP12 probe
CP12 probe: how many bands? how long is each band?
- 4: 2 silver, 2 black bands
- each band is 3mm long
CP12 probe:
used for measuring? used to carry out which periodontal examinations?
- pocket depths
gingival margin levels
loss of attachment - 5 point exam, double periodontal charts
WHO/CPITN probes: used for which periodontal examination?
only for the basic periodontal examination (BPE)
name 2 other pressure sensitive periodontal probes
- TPS probe
- florida probe
name and describe the basic periodontal pocket types
- false pockets: base of pocket at/coronal to ACJ (no LOA)
- true pockets: base of pocket is apical/below ACJ (LOA present)
when are plaque & bleeding + double periodontal charts recorded?
after an initial BPE or 5 point exam that indicates significant active periodontal disease is present, which requires more complex management
at which points of treatment are double periodontal pocket charts recorded? what does each recording determine?
pre-treatment: initial charts recorded to determine periodontal diagnosis and treatment plan
post-treatment: reassessment charts to determine treatment outcome. comparison with pre-treatment chart shows show perio measurements have changed during treatment
double periodontal pocket charts: what are the 4 periodontal landmarks?
- ACJ
- gingival margin
- base of pocket
- LOA
what are the 2 measurements in double periodontal pocket charts? how is each one measured?
- gingival margin levels: gingival margin to ACJ
- pocket depths: gingival margin to base of pocket
if gingival margin is apical to ACJ, how is the measurement recorded?
recorded as just a number, e.g. 6mm
if gingival margin is covering/coronal to ACJ, how is the measurement recorded?
recorded as +6mm
angulation of probing: how should probe be positioned for accurate pocket measurements?
probe should be parallel with root surface
- consider 3D anatomy of root
gingival margin and pocket depths are recorded at which six points per tooth?
buccally:
mesial buccal
mid buccal
distal buccal
lingually:
mesial lingual
mid lingual
distal lingual
double periodontal pocket charts: upper half of chart represents?
upper and lower buccal surfaces
double periodontal pocket charts: lower half of the chart represents?
upper and lower palatal/lingual surfaces
double periodontal pocket charts: thick black line represents? thin black line represents?
- ACJ
- 2mm increments apical from the ACJ
double periodontal pocket chart recording: gingival margin levels - recorded in what colour ink?
- red
double periodontal pocket chart recording: periodontal pocket depths - recorded in what colour ink?
blue
what are the 5 clinical indicators of periodontal disease?
- pocket depths
- BOP
- mobility
- furcation involvement
- LOA
famous 5: pocket depths
pockets =/>4mm, what to record?
- which teeth
- how deep
- which surfaces
famous 5: BOP
how is BOP recorded?
record:
which teeth
which sites (surfaces)
famous 5: mobility
recorded with which index? recorded as?
- miller’s index
- recorded as:
which teeth, how mobile (miller’s degree)
famous 5: furcation
how is furcation recorded?
which teeth
which site
which grade
famous 5: LOA
how is LOA recorded?
which teeth
which surface
severity (mm)
what leads to overestimation in periodontal pocket depth?
- excessive probing force
- periodontal probe too sharp
- incorrect angulation
- pocket inflammation (collagen loss, reduced resistance to probing)
what leads to underestimation of periodontal pocket depth?
- insufficient probing force
- obstructions: calculus, overhangs
- root morphology
- periodontal probe too thick
- patient tolerance
- incorrect angulation (extreme)
