ABSTRACT:
A self contained heated root canal dental instrument which combines the operations of a root canal spreader, a root canal condenser and a root canal filling material heater is provided. The instrument has batteries in its handle for use as a power source for heating root canal filling material and employs a non-corrosive dental tool that has a resistive element in its tip to provide the heating when electricity from the batteries is conducted through the tip. A method for making the dental tool is provided which comprises threading a resistive element through a cannula which is used as a dental tool.
