A small, shallow, hand-held concave vessel made of glass or metal used to mix dental materials chairside prior to application to the patient during dental procedures. The user dispenses the required amount of component materials into the device and mixes them by hand (e.g., with a spatula) until the consistency of the mixture is appropriate. It is most often used for prophy and fluoride treatments, for mixing composite materials, acrylics, cements, and amalgams. This is a reusable device.
