Let’s Find Out How Much You Know About Instrumentation

Understanding how to implement different body positions and alternative fulcrums will allow clinicians to maximize the use of sickle instruments in calculus removal. How does your understanding stack up on alternative fulcrums with sickle scalers?


The U15 Towner, SHG 6/7, and SH 6/7 sickle designs are commonly used in the anterior areas of the mouth; however, they can be used on posterior teeth with correct fulcrum placement.

Correct! Wrong!

The shank of the 204SD contra-angle sickle is longer and more open than the 204S, improving access to which aspects of the teeth?

Correct! Wrong!

A secure fulcrum and proper modified pen grasp are needed before a clinician begins instrumentation. What are the undesirable outcomes a clinician can cause if proper sickle instrumentation technique is not implemented?

Correct! Wrong!

When using a sickle scaler for maximum access on mandibular posterior teeth, the patient should be in a semisupine position with the chin tucked down toward the chest and the clinician sitting.

Correct! Wrong!

To treat teeth surfaces positioned away from the clinician, an intraoral opposite arch fulcrum should be used on the maxillary incisors, standing at the 1:00 body position with the arm at what position?

Correct! Wrong!

When instrumenting maxillary anterior teeth toward the clinician, the operator sits at the 9:00 position; however, the clinician can chose to stand at the 1:00 position when accessing surfaces away from him/her.
