G. Mod. 12 Perio and Basic Probe Techniques Flashcards
Periodontal Probe
Has a blunt, rod shaped working end that may be circular or rectangular in cross section and is calibrated with mm markings
What is the use of a probe?
Detect and measure perio pockets
Distance between gingival margin and base of periodontal pockets
Other uses of a probe (7)
-Clinical attachment loss (cal)
-Extent of recession of the gingival margin
-width of attached gingiva
-size of intraoral lesions
-assess bleeding on probing
-determine mucogingival relationships
-measure longitudinal response of periodontium to treatment
Healthy probing depth
1-3 mm
Periodontal pocket indicated at?
4mm+
Gingival sulcus
V shaped space between the free gingiva and the tooth surface
Probe inserted here to assess health
Touches near CEJ
GM to coronal most part of junctional epithelium
Free gingiva
Unattached portion of gingiva that surrounds tooth in region of the CEJ
Turtleneck, can be moved away
Attached gingiva
Tightly connected to cementum on cervical third of root and to the periosteum (connective tissue) of alveolar bone
Junctional epithelium
Health vs periodontitis
Tissue that forms base of sulcus by attaching to enamel of the crown near the CEJ
In health it attaches Apical (above) CEJ on enamel
In periodontitis it attaches to cementum of tooth root (below CEJ)
Periodontitis
Bacterial infection of all parts of the periodontium
Which includes Gingiva, perio ligament, alveolar bone and cementum
Defined by presence of perio pocket
Periodontal pocket
Destruction of
Results from destruction of alveolar bone and the periodontal ligament fibers that surround the tooth
Common to measure 5-6mm
Forms from apical migration of JE—Probe contacts root BELOW CEJ
Gingival pocket
Occurs because of detachment of
And
Increased size of
Deepening of gingival sulcus from
1-detachment of coronal portion of JE from tooth
2-increased tissue size due to swelling (inflammation)
Walking stroke
Movement of a calibrated probe around the perimeter of the base of the sulcus
Limitations of probing measurements
Position of gingival margin
-significantly coronal to the CEJ (swollen)
-Apical to CEJ (Below) —can underestimate true extent of perio destruction
-reading errors from naturally occurring states
Calculus, overhang, crowns contour
-reading errors due to probing technique and equipment
Incorrect angulation
Incorrect pressure
Misreading probe
Recording wrong measurements
UNC 12 Probe
Color coded at 4 and 9 mm
Periodontis
bacterial infection of all parts of the periodontium including the gingiva, periodontal ligament, alveolar bone, and cementum.
Probe depth >3mm
Perio pocket
Could be gingivitis but look at X-ray to confirm
Probe tip touches root below CEJ
Interdental gingiva (papilla)
Gingiva that fills area between adjacent teeth apical to contact area
Probing depth
Distance from — to —- in —-
Distance in mm from GM to base of sulcus or perio pocket
Probing
Walking/Bobbing tip of probe along base of sulcus or pocket to assess health status of perio tissue
Probe tip
1-2 mm of SIDE of probe, tip to tooth, kept in contact with tooth surfaces throughout walking stroke
Parallelism
Probe working end positioned parallel as possible to root surface
Must be parallel in mesiodistal and faciolingual dimension
Walking stroke
Bobbing made in sulcus or pocket while keeping probe tip against and in alignment with root surface
Junctional epithelium
Characteristics
Forms base of sulcus or pocket and feels SOFT and FLEXIBLE when touched with probe tip
