Abstract: A portable dental system comprises a drill system for drilling, a fluid delivery system irrigating the drill system and the patient's mouth, a battery for powering the drill system and the fluid delivery system, control circuitry for controlling the drill system and the fluid delivery system, and a housing. The housing protects the drill system, the fluid delivery system, the battery and the control circuitry, and defines a cavity sized to retain them. With the battery internal to the portable dental system, the system can be used in any environment that does not include an external power source. The control circuitry includes a power circuit for powering the drill system and the fluid delivery system from power provided by an external source, such as a 24-volt DC vehicle battery, a 12-volt DC vehicle battery, or a generator that can generate 110 volts AC or 220 volts AC. The portable dental system weighs less than 35 lbs and may be easily carried.

Abstract: An endodontic obturator includes a body and a disposable cartridge containing gutta percha that is couplable with the body. By containing the gutta percha in a disposable cartridge, a dentist or other medical technician does not have to clean the body or other components of the obturator, thus reducing the amount of time required to clean the obturator after use. The obturator also includes a heater operable to heat the gutta percha in the disposable cartridge and a thermal barrier operable to resist the flow of heat from the heater to the rest of the body. In addition, the obturator includes a mechanism operable to generate pressure in the disposable cartridge to dispense the gutta percha. With the thermal barrier, a portion of the obturator's body that a dentist or other medical technician might hold while injecting gutta percha into a patient's tooth may be kept relatively cool.
