Which of the following descriptions provides a visual cue to the clinician to correct the tuning of a standard ultrasonic insert?

Generally, the standard working ends should be adjusted to a resonance frequency for maximum energy output. This level of tuning puts the insert at peak efficiency suitable for light to heavy deposit (dental calculus) removal. The covering of a large area by very fine droplets is a way to describe the widest spray of mist that the operator is striving to achieve when the frequency is adjusted "in phase" for a standard insert. If a narrow steady stream of water is present, it is not adjusted "in phase" for the maximum energy output necessary to remove dental calculus efficiently. This description, large droplets of water, might occur in the tuning process and describes water when it is neither "in phase" nor "out of phase." Status of the insert or tip should be reassessed for cracks, O-ring maintenance on the insert, or other problems. This description describes tuning for the instrument toward the "out of phase" status, which is indicated for thin working ends. If a steady stream of water accompanies the water spray, the working end is not adjusted for maximum energy output needed for the standard designs.
