Abstract
A self-contained root canal dental instrument that combines the operations of a root canal spreader, a root canal condenser, and a root canal filling material heater in a less expensive and easier to replace plugger unit. A different heating circuit using balanced resistor elements in both the hand piece and the tip makes use of the instrument more cost effective for the dentist. The instrument combines a sterilizable condenser tip with the capability of achieving the correct heating temperature via standard AA alkaline batteries.
