Abstract: A method that includes the step of using a person's fingers to push a dental composition into engagement with a damaged tooth surface of a damaged tooth thereby adhering the dental composition to the damaged tooth surface and covering at least a portion of the damaged tooth surface. The dental composition includes a base material comprising at least one of the following compounds chosen from the group consisting of: a product consisting of one or more hydrocarbon-based waxes that may also include inorganic fillers and/or organic fillers; an uncured, uncrosslinked silicone high consistency rubber base; and a hydrophobic water insoluble solid material. The base material has a coating composition on one or more surface of the base material wherein the coating composition comprises: one or more desensitization ingredient and at least one dry, powdered hydrophilic polymeric substance.

Abstract: There is provided a method and apparatus for simultaneously extruding two triple-wall pipes. A first extruder is connected to a first die in order to form the inner and outer wall of a first pipe and a second extruder is connected to a second die in order to form the inner and outer walls of a second pipe. A third extruder is connected to a Y-block which splits the output from a third extruder into two channels, one leading to the first die in order to form the foam core middle wall of the first pipe and the second leading to the second die in order to form the foam core middle wall of the second pipe.
