"A Comparison Shopper`s Guide to Ultrasonic Scalers," available from Parkell, Inc., is written for dentists and hygienists considering the purchase of a new power-scaling device. It provides brief descriptions of virtually every scaler available in the U.S., along with telephone numbers for contacting 14 different suppliers.
The nonpromotional publication discusses various options available and often-overlooked questions to ask when talking to suppliers. It explains the difference between sonic and untrasonic scalers; between magnetostrictive and piezo designs; and between auto-tune and manual-tune scalers.
