How do you select the correct end of a double ended explorer?

Place terminal shank parallel to the tooth, if the handle is going outside of the mouth it is correct.

1

How do you adapt an explorer to a tooth surface?

1. Tip to Tooth
2. Pivoting on the Fulcrum
3. Rotating (fingers)

2

What is the assessment stroke used with in an explorer?

1. Wrist Motions (pecking or side to side)
2. Overlapping strokes (vertical or oblique)
3. Lead w/tip
4. Smooth/Continuous Strokes remaining in the sulcus
5. Explore the entire depth of the pocket

3

What is the adaption pattern for exploring teeth on both arches?

Posterior to Anterior

4

What is the adaptation pattern per maxillary tooth?

Midline to distal

5

What is he adaptation pattern per mandibular tooth?

Toward surfaces to Away surfaces

6

What is the adaptation pattern for posterior lingual and facial surfaces?

Distal line angle to distal
Distal line angle to mesial

7

How do you detect supracalculus?

Direct observation and AIRMIR

8

How much pressure do you use with an explorer?

Light and Firm

9

What part of the explorer is adapted to the tooth surface?

The working end; about 1-2mm of the tip of the instrument

10

How many strokes are needed to explore a root surface?

Depends on the pocket depth and area of tooth surface.

11

What is the purpose of exploring tooth surfaces?

To find calculus, caries, and in general irregularities.

12

What are the different CEJ relationships?
(HINT: OMG)

Overlap (60%)
Meet (30%)
Gap (10%)

13

What irregularities can we find with an explorer that is considered an elevation?

Deposits = (calculus and stain)

Enamel pearls = round excess enamel usually seen in furcation of maxillary molars.

Unusual CEJ = overhanging restorations

14

What irregularities can we find with an explorer that are considered to be depressions?

Decalcifications
Caries
Abrasion erosion pits
Root anomalies
Defective Margins of Restoration

15

True or False; it is ok to poke decalcifications (white spots)

False, you should never poke decalcification spots

16

What typically causes abrasion erosion pits?

Tooth Brush

17

What common types of calculus formations exist?

Spicules-class 1
Ledge-class 2
Ring-class 3
Veneer - smooth

18

Why do we not want to insert an explorer into a suspicious carious lesion?

May result in the rupture of the surface layer covering early lesions causing more damage.

19

What does tactile sensitivity mean?

Sense of Touch

20

What is tactile sensitivity?

The ability to distinguish types of degrees of roughness and smoothness on the tooth surface.

21

On what finger should you feel vibrations?

Middle finger

22

Where is most calculus left behind?

The CEJ

23

What are explorers used for?

Detection or assessment to find calculus, furcations and decay on tooth and root surfaces. Confirm direct observations.

24

What is the extreme end of an explorer called?

Sharp point

25

What is the working end of an explorer called?

The tip

26

Which explorer do you use to detect calculus?

Shepard's Hook

27

Calculus has to have a high content of what to show up on an x-ray?

Calcium

28

What is the col?

The depression above the contact area.

29

What is iatrogenic dentistry?

Dentists sometimes create an overhang purposely when doing restorations.
