what is an explorer?

An assessment instrument with

a flexible wire-like working-end

-Used to detect subgingival

calculus deposits and anatomic

features

what is explorers made out of?

-Made of flexible metal that

conducts vibrations from the

working-end to the clinician’s

fingers

What part of the explorer is adapted 1 to 2 mm to the tooth surface for detecting calculus deposits?

explorer tip

Which explorer has a tip bent at a 90-degree angle to the lower shank, is ideal for subgingival use, and has a point that is not used for detection?

11/12 explorer

Which part of an explorer is the section of the shank that is nearest to the explorer tip?

lower shank

Which explorer has a tip bent at a 90-degree angle to the lower shank and a straight lower shank?

orban type (17/18 explorer)

What are the advantages of the Orban explorer?

• Tip allows the back (not the point) to be directed against the soft tissue base of the sulcus/pocket

• Excellent for use on anterior teeth

• Ideal for detecting calculus in narrow or deep pockets

what are the disadvantages of the orban explorer?

the straight shank makes it difficult to use on line angles, mesial, and distal surfaces of posterior teeth.

Question:
Which explorer has a tip bent at a 90-degree angle to the lower shank and a long, complex shank design?

11/12 explorer 

what are the advantages of the 11/12 explorer? 

• Smooth back of the tip can be directed against the soft tissue base of the sulcus or pocket

• Complex shank design allows excellent use on both anterior and posterior teeth

what are the disadvantages of the 11/12 explorer?

none

What is an assessment stroke, and what is it also called?

• A stroke used to detect calculus deposits or other tooth surface irregularities

• Also called an “exploratory stroke”

What are fungiform papillae?

Mushroom-shaped, scattered on tip and sides; have some taste buds.

What are circumvallate papillae?
