The present invention relates to devices for dispensing and mixing multi-component materials, in particular for viscous fluid materials. The device is adapted for dispensing multi-component compositions that are kept separate prior to use and that are also typically mixed prior to use to properly combine the constituents in order to form an active and/or working composition. In one embodiment, a device is adapted to contain at least one vessel containing a material prior to use. The device also includes a mechanism for evacuating the at least one vessel and a mechanism for mixing at least one material prior to use. The material may contain multiple constituents in one vessel or more than one vessel.

A toy musical playset having a teapot with xylophone keys which is filled with styrene plastic beads, a number of pots with xylophone keys and a pan with a xylophone key, tambourine symbols and musical ribs. The pots, pan and teapot may be stacked on top of each other. The toy pan may be used like a tambourine, or the musical ribs may be used with a toy spatula or spoon to make musical sounds. In addition, the toy teapot filled with beads may be shook to produce musical sounds. A child may strike the xylophone keys with a spoon producing musical sounds during play when the pots, pan and teapot are in a stacked configuration, or when they are spread out on top of a table. The pots or pan may also be hung on a child's belt.

A method for continuously evaluating the effectiveness of debridement of a root canal of a tooth, the tooth having an open access cavity and an apex end, includes delivering a fluid to the open access cavity of the tooth, evacuating the fluid near the apex end of the tooth such that the fluid flushes most of the root canal before being evacuated, and continuously evaluating the evacuated fluid for at least one of a presence of debris, a concentration level of the debris, or a type of the debris. An apparatus for use in debriding a root canal of a tooth includes a microcannula or a macrocannula configured to evacuate a fluid in the root canal, and a sensing mechanism fluidically coupled to the microcannula or the macrocannula, the sensing mechanism configured to continuously sense debris in the evacuated fluid in real time.
