A Right-Handed Clinician Is Working on the Buccal Aspect of Tooth

A right-handed clinician is working on the buccal aspect of tooth #2. (For a left-handed clinician, this area would be equivalent to the buccal aspect of tooth #15.) The clinician is using a Gracey 13/14 curet and retracting the client's cheek with a mouth mirror. The clinician's neck is bent excessively as she works. What correction should the clinician make for more ergonomic positioning?

A) Ask the client to turn her head slightly away from the clinician
B) Turn the mirror head so that the reflecting surface can be used to view the distal surface
C) Ask the client to turn toward the clinician and lower her chin down toward her chest (chin-down position)
D) Raise the client's chair up to bring the working area level with the clinician's eye level
