Periodontal Assessment: Periodontal Probing Technique and CAL Flashcards
Identify the millimeter markings on the williams probe
millimeter grooves at 1-10 mm (4 & 6 are missing to avoid confusion)
Identify the millimeter markings on the UNC-12 and UNC-15 probes
UNC-12: markings at each millimeter, color-coated at 4 and 9 mm
UNC-15: markings at each millimeter, color-coated at 4, 9, and 14 mm
Identify the millimeter markings on the World Health Organization Probe
Has ball on end, markings at 3.5, 5.5, 8.5, and 11.5 mm (goes to 16mm)
Identify the millimeter markings on the Goldman Fox probe
Flat, grooves at 1-10 mm (4 and 6 are missing)
Identify the millimeter markings on the Novatech probe
Markings at 3, 6, 9, 12
Identify the millimeter markings on a plastic probe
3, 5, 7, 10
What is the gingival sulcus?
A shallow, v-shaped space between the free gingiva and the tooth surface
What is the gingival margin?
Where the free gingiva meets the tooth in a thin rounded edge
What is the junctional epithelium?
The tissue that forms the base of the sulcus by attaching to the enamel of the crown near the CEJ
What is the depth of a clinically normal gingival sulcus?
1-3 mm
What surfaces has the least amount of depth?
The facial surfaces
What surface is the deepest?
The mesial and distal surfaces
What is peridontitis and how is it identified clinically?
- Bacterial infection of all parts of the peridontium.
- The presence of a periodontal pocket (sulcus that is greater than 3mm)
What is a gingival pocket?
Deepening of the gingival sulcus.
What causes a gingival pocket?
- Detachment of the coronal portion of the JE from the tooth
- Increased tissue size due to swelling
What is a pseudo-pocket?
The gingival tissue swelling resulting in an increased probing depth (from gingivitis)
What is the deeper probing depth of a periodontal pocket caused from?
Apical migration of the JE
How many zones per tooth is there? What are they?
- Distofacial
- Facial
- Mesiofacial
- Distolingual
- Lingual
- Mesiolingual
How many readings per zone?
Only one and always the deepest reading
What is the probing depth?
Distance in millimeters from the gingival margin to the base of the sulcus or periodontal pocket
Explain insert and adaption of the periodontal probe
Once the probe is inserted, the working-end is kept PARALLEL and FLAT to the root surface
What is the walking stroke?
The movement of a probe around the perimeter of the base of a sulcus or pocket
It is essential to evaluate the entire ____________ of the pocket base
Circumference
Explain what you’re doing in the walking stroke
Move the probe up and down in short bobbing stroke while moving in 1 mm increments
The probe is removed from the sulcus with each upward stroke. True or false?
False: the probe is NOT removed
