The present invention relates to a capsule for use in dispensing dental composite. The capsule includes a hollow body having a wall defining an interior space of the body. The body includes a proximal end and a distal end having a dispensing orifice. The wall comprises a polymeric material, and a time-temperature indicating material and/or a temperature indicating material. The capsule includes one or more composite resins positioned in the interior space of the body.

A self-heating electric plugger/syringe needle (10/70) with the conductive element (50) on the external surface of the needle (10/70) is described. The needle (10/70), which can be divided into shank (30) and tip (20) portions, is hollow and is made of an electrically resistive material. A conductive element (50) located on the external surface of the needle runs along the length of its shank (30) and the length of its tip (20). An insulating material (60) located between the conductive element (50) and the external surface of the needle runs along the length of the shank (30). The conductive element (50) contacts the tip (20) of the needle, causing the needle to self-heat when electric current is supplied. A method for filling a root canal using the self-heating electric plugger/syringe needle (10/70) is also described.

The present invention provides an improved root canal filling point/cone having a structure that can be manufactured precisely to result in better obturation with less micro-leakage. One aspect of the present invention is directed to a molded root canal filling point having progressively decreasing tapers from the smaller tip end to the larger end. Another aspect of the present invention is directed to a thermo-pressure molding process for manufacturing root canal filling appliances (e.g., Gutta Percha points). A further aspect of the present invention is directed to the structure of the mold for undertaking thermo-injection molding
