Abstract: A dental scaler system consisting of an ergonomically designed body and interchangeable tip assemblies designed to minimize fatigue due to prolonged strain from instrument grip and use. The device has a centrally located opening shaped to receive the index finger for a comfortable reduced strain grip. The opening is shaped such that it is possible to maneuver and rotate the device around the index finger allowing the user to change from one working end to the other in a single handed manner while continuing to hold the device. The device is designed to utilize detachable and interchangeable tips including spacers to adjust the overall length of the device or as a one piece unit with fixed instrument tips.
