Visual inspection, tactile test, auditory

What three practices are used for tests instrument sharpness?

Fulcrum, lateral pressure, reinforcement scaling, joint hypermobility

What are the four main components involved in Hand-Activated Instrumentation?

Angulation, adaptation, activation

What are the three main stroke principles?

Exploratory, scaling, root planing

What are the three types of strokes?

Vertical, oblique, horizontal

What are the three stroke movements?

Blade size

In curet selection what is the more important factor?

Site

In instrument blade selection the hygienist determines the correct instrument working end to use for tooth surface to be scaled and majority of treatment instruments are ____ specific.

Fulcrum

A finger used to stabilize the hand during instrumentation; improves precision of instrumentation strokes and prevents sudden movements that could injure the patients. Purpose is to serve as a “support beam” for the hand.

Wrist aligned with long axis of forearm, avoid blinding

What are the key guidelines for neutral hand and wrist position?

One to four teeth away

How far away should you fulcrum be from the tooth being worked on so that is it out of the line of fire?

Down; Up

Handle positions for mandibular surfaces have the palm ____, while maxillary surfaces have the palm _____.

Longer; Shorter

Impact of Finger Length: Clinicians with _______ fingers may establish a grasp higher on the instrument handle; Clinicians with ________ fingers may establish a grasp lower on the tapered portion of the instrument handle.
