Historically, periodontal scaling and root planing were accomplished using hand instruments because ultrasonic
scalers were originally designed for gross scaling and removal of supragingival calculus.
As we know, the ultrasonic
wave is a kind of elastic waves propagating in the medium with higher frequency.
Raw materials were sawed into 21 by 21 by 5-mm samples, put into distilled water, and treated with ultrasonic
parameters, as shown in Table 1.
The overall ultrasonic
pulse velocity tester market worldwide is set to grow with a CAGR of 5.9% during the forecast period.

According to Aurand, ultrasonic
food cutting systems are often used in the following applications:
EJ Electronics are one of the biggest service centres for ultrasonic
cleaning systems and tanks.
In this work, we fabricated the miscible PC/PMMA blends by using the ultrasonic-assisted transesterification process and systematically investigated the effects of sonication time and ultrasonic
power on the transesterification process.
It emits ultrasonic
and electromagnetic waves at 20-55kHZ that protects up to 200 m2 radius.
The company built its first ultrasonic
slitter for the hook and loop industry in the late 1970s.
The ultrasound-assisted extraction was performed on an ultrasonic
homogenizer (JY92-II, Ningbo Scientz Biotechnology Co., Ltd., China).
