There is an additional advantage to the ultrasonic over sonic. However, it is not terribly effective on heavy calculus, and it is useless on flinty old accretions that can be easily removed with an ultrasonic scaler. The sonic scaler is a low-power device that removes plaque and fresh calculus. The primary difference between sonic and ultrasonic scalers is power. The pattern of vibration is much more linear than the sonic scaler, tracing the letter "I" or a very narrow ellipse as it vibrates. Ultrasonics vibrate at much higher frequencies than sonic scalers (25,000 cycles per second or higher). They must be connected to a water source and they plug into an electrical wall outlet. Ultrasonic scalers involve a power-unit box that sits on the counter. Research has shown that the tip of a sonic scaler moves in an orbital pattern, tracing the letter "O" as it vibrates at approximately 3,000-9,000 cycles per second. They sit conveniently in the delivery unit and hook up to a conventional air/water handpiece connector. Sonic scalers, like the Titan®, are small handpiece-size devices. Decision #1: Do you want a sonic or ultrasonic scaler? We've tried like the devil to make it as accurate and unbiased as possible, but the prudent shopper will check our facts by calling the manufacturers at the numbers listed below. This short article contains information gleaned from manufacturers' publications and research literature. However, we believe that anything we can do to encourage dentists, hygienists, and assistants to shop around before they purchase (to carefully compare features, after-sale service, and independent clinical evaluations) will be to their advantage.
