Flashcards in Quiz 5 exploring Deck (46):
1

What is the explorer tip?

Working end which is 1-2 mm long

2

What is the explorer tip made of?

Flexible metal to detect tactile senation

3

What part is used to detect calculus

The side of the tip, not the actual tip

4

How do you find the working end?

Lower/terminal shank should be parallel to tooth surface
Place on distal of premolar

5

What is the shepard hook/straight explorer used for?

Supragingival exam of margins and restoration or to assess sealant restoration(definite hard tissues)

6

What is the curved explorer used for?

Calculus detection in normal sulci or shallow pockets

7

What is a pigtail and cowhorn explorer used for?

Calculus in normal sulci or shallow pockets no deeper than cervical third of root

8

What is orban explorer used for?

Insertion into narrow pockets.
Assessment of anterior root surfaces and F and L surfaces of posterior teeth
Difficult to adapt to proximal surfaces of posterior

9

What is 11/12 explorer used for?

Assessment of root surfaces on anterior and posterior, equally useful

10

What is the composition of subgingival calculus

Often flattened due to pressure of pocket wall against tooth
Deposit built up layer by layer, near CEJ rather than JE

11

Spicule

Usually under contact area at line angle or midline of tooth

12

Nodule

Larger spicule type w/ a crusty or spiny surface

13

Ledge

long ridge running parallel to gingival margin, common on all tooth surfaces

14

Ring

Ridge running parallel to gingival margin

15

Veneer

thin, smooth coating w/ shield like shape on potion of root surface

16

Finger-like formation

Long, narrow deposit running parallel or oblique to long axis of root

17

What is the mm of stroke for explorer?

2-3mm

18

What are the errors associated with explorers?

Not adapted
Too much pressure
Not deep enough in the pocket (need to be at base)

19

What are we looking for with the 11/12 explorer

Tooth anomlaies
Calculus
Overhangs
Wrong restorations

20

What happens if too much pressure is applied?

You feel tooth topography and will continue to take off cementum

21

Why is the explorer thin?

To disseminate between tooth and calculus

22

Basic instrumentation of explorer

Insertion, angulation, and adaptation is one fluid motion

23

What's the movement under the gum?

Always done w/ motion, follow terminal shank so always adapted

24

What happens if your instruments aren't sharp?

With dull blades comes increased pressure, Not able to remove calculus even though everything else is sound

25

Where does the hypersensitivity come from?

Removing the cementum

26

How do you adapt to the tooth w/ the explorer?

Roll the back of the instrument away from the tooth to maintain adaptation

27

Motion Activation, helps prevent RSD

Handle roll, Wrist knock, Pivot knock

28

Subgingival Assessment w/ 11/12 explorer
Beginning

Adapt 1-2mm of working end at tooth surface and slide under gingival margin, down to JE or base keeping 1-2mm in constant contact w/ root surface

29

Subgingival Assessment w/ 11/12
Activation

Active stroke w/ wrist activation to move tip forward, apical and oblique w/ overlapping strokes
Control stoke w/ 2-3mm to remain in sulcus and maintain 1-2 mm working end in contact

30

Subgingival Assessment w/ 11/12
End

1-2mm tip will always lead stroke while in contact driven by wrist activation
Exploring proximal will require strokes to cover more than 1/2 the interproximal

31

Vertical assessment stroke
Anterior

used on F, L and proximal surface

32

Vertical assessment stoke
Posterior

Used primarily on mesial and distal surfaces

33

Oblique assessment stroke

Strokes across F or B surface
Down, up and over stroke produced at a slight angle

34

Horizontal Stroke

Strokes made in a perpendicular direction to long axis of tooth

35

11/12 Exploring anterior teeth

Need to flip handle to do either surfaces towards or away for each aspect,
Sequence follows 1/2 of surfaces towards then surfaces away
Overlap at midline each time you enter

36

What does the explorer do to the anterior teeth?

Wrap around each of the surface

37

Sequence of exploring
Posterior

Adapt explorer to mesial to find correct working end
Start at distal
Enter at DLA and continue w/ vertical and oblique strokes into col area
Reenter at DLA and move forward w/ vertical and oblique stokes to mesial col

38

Type 0 Health

No clinical changes from health in gingival color, form, position and surface appearance. No bleeding upon probing. No connective tissue loss. No bone loss, 0-3mm present

39

Type 1 Gingivitis

Gingival inflammation characterized clinically by changes in color, gingival form position and surface appearance. Bleeding upon gentle probing. No connective tissue attachement loss. No bone loss. 0-3 mm sulci present

40

Type 2 Early Periodontitis

Progression of gingival inflammation into deeper perio structures and bone crest. Bleeding upon gentle probing. Slight connective tissue lost. Slight bone loss. 3-4 mm sulci present. (CSN will use this type to classify cases w/ >3mm resulting from inflammation)

41

Type 3 Moderate Periodontitis

More advanced stage of type 2 w/ increased destruction of perio structures. Bleeding upon gentle proving. Moderate connective tissue attachment loss. Moderate bone loss. Possible mobility. Possible furcation involvement. 4-6mm pocket present. Refer to specialist

42

Type 4 Advanced Periodontitis

More advances of type 3 w/ advanced destruction of perio structures.Bleeding upon gentle probing. Advanced connective tissue attachment loss. Advanced bone loss. Mobility. Furcation involvement 7+ pockets. Refer

43
