Prior to the synthesis of PtM/rG-O nanocomposites, the as-prepared GO was dispersed in deionized water by ultrasonication (KQ2200E system, Kunshan Ultrasonic Instruments Co., Ltd, 40 KHz, 80 W) for 3 h.
In a typical DNA electrophoresis experiment, the as-prepared GO was dispersed in deionized water by ultrasonication (KQ2200E system, Kunshan Ultrasonic Instruments Co., Ltd, 40 KHz, 80 W) for 3 h.
Bipolar and ultrasonic instruments were used for colpotomy.
High-power ultrasonic instruments have been used extensively for dispersing soil particles and aggregates.
They concluded that the thinning of the lateral wall of the sinus by using ultrasonic instruments or bone scrapers seemed to reduce the incidence of accidental sinus membrane perforations.
In another RCT, topical CHX gel application + full mouth disinfection + CHX mouthrinse (2×/day) and tonsil spraying (1×/day) for 14 days was compared with OHI + mechanical debridement (plastic scaler + polyetheretherketone-coated ultrasonic instruments) + full mouth scaling alone.
