An improved method for cleaning and sterilizing medical and dental instruments () employs the use of a banding device () to segregate and hold together medical or dental instruments () after use in a particular procedure. The banded instruments () are then cleaned and sterilized. This method essentially eliminates the time and effort formerly required when unsegregated instruments were mixed with other instruments for cleaning and sterilization and then stored according to the particular procedure for which they are intended and/or according to the intended particular user thereof.

Method for cleaning and sterilizing dental and medical instruments

A dental apparatus includes a tray that is shaped and dimensioned to fit over at least some of the teeth of a patient. The tray defines a tunnel through which to evacuate saliva from the mouth of the patient. The tray includes a connector portion for coupling a suction source to the tunnel, and the tray defines at least a first opening in fluid communication with the tunnel through which saliva may be sucked from the mouth of the patient into the tunnel for communication to the suction source. The apparatus may take the form of a fluoride treatment tray or an impression tray, including a bite registration tray, it may include multiple trays, and it may define additional spaced-apart openings in fluid communication with the tunnel to facilitate evacuation of saliva from a larger region within the mouth of the patient. Preferably, the connector portion is configured to receive an end of a conventional saliva ejector in a close fitting relationship in order to couple a commonly used suction source to the tunnel. In one version, the tray is formed from two layers of transparent material to facilitate viewing of saliva being evacuated through the tunnel. A dental apparatus for isolating a field within the mouth of a patient is also disclosed that includes an integral saliva evacuation tunnel.
