4. Insertion is the action of moving the working-end of an instrument beneath the gingival
margin and into the sulcus or pocket. For insertion, the instrument face should be positioned as
far away from the tooth surface as possible.
A. Both statements are true.
B. Both statements are false.
C. The first statement is true; the second statement is false.
D. The first statement is false; the second statement is true.
Answer: C

5. For successful instrumentation, correct angulation of the working-end must be maintained
throughout the instrumentation stroke. Incorrect angulation can result in a burnished calculus
deposit.
