Abstract: Implementations of a tooth brush are provided. In some implementations, the tooth brush comprises a handle and a head attached to the handle where the head comprises three gears and three brushes attached to the three gears respectively. In some implementations, the tooth brush is configured such that one brush makes contact with the occlusal surfaces of a plurality of teeth and the remaining brushes make contact with the buccal side and lingual side of the plurality of teeth. In some implementations, the tooth brush further comprises a splash guard. In some implementations, the tooth brush further includes a suction tube to remove debris from the mouth. Methods of using the tooth brush also are provided.

Abstract: A dental mixer apparatus including an upright mixing chamber having an upper open end for receiving dental impression materials and a plunger member suspended coaxially upon an elongated rotary driven mixer shaft for vertical reciprocable movement between a lower operative position in which the plunger is received within the mixing chamber and an upper inoperative position above the mixing chamber. A rotary mixer head is driven by the mixer shaft below the mixing chamber for mixing the materials within the mixing chamber. A suction conduit is provided to suck air from the mixing chamber in order to minimize voids and bubbles within the mixed ingredients. The mixer shaft is supported by a support bracket which is pivotally mounted to permit the mixer shaft and plunger to swing away from their normal vertical position above the mixing chamber to provide more working space above the mixing chamber.
