The dentist uses the slow-speed handpiece and round bur to remove caries and to access the pulp chamber. The dental assistant may quickly rinse the area to improve the dentist's field of view.

The dentist may want to use the endodontic spoon excavator to remove caries and the endodontic explorer to locate the pulp chamber and canal openings.

The dental assistant passes a barbed broach for the dentist to remove pulpal tissues from within the root canal. The dentist may want several broaches, especially if the tooth has more than one root.

Step #7

Back 8

The dental assistant passes a #10 or #15 reamer with stoppers to measure the length of each canal. The dental assistant exposes a radiograph so the dentist can measure the length of each canal with the file or reamer in place. The radiograph and working length of each canal are recorded in the patient's chart.

The dental assistant passes additional files in pregression until the proper width and length of the canal are achieved. The size and length of the final file used are recorded in the patient's chart.

Step #9

Back 10

The dental assistant passes the irrigating syringe with irrigating solution to the dentist. The dentist irrigates the canal. The dental assistant must keep the tip of the HVE very close to the tooth so the irrigating solution is efficiently aspirated and not allowed to splash the patient or dental team.

Step #12

Back 13

A master gutta percha point is selected that matches the width size of the last file used in each canal. The dental assistant exposes a radiograph to verify the proper length and seal.

Front 14

Step #13

Back 14

The dental assistant mixes the endodontic sealer to a creamy consistency and passes it to the dentist so they can coat the tip of the master gutta percha point. The dentist places the gutta percha with cement into the canal.

Step #14

Back 15

The dental assistant passes the endodontic spreader and additional accessory gutta percha points and continues to pass the spreader and an additional point until each canal is full.

Step #15

Back 16

The dental assistant passes the endodontic condenser and prepares the torch. The dental assistant holds some 2x2 gauze squares and holds the HVE tip close to the tooth.

Front 17

Step #16

Back 17

The dentist heats the tip of the endodontic condenser and melts off the excess gutta percha material. It is important to adequately heat the instrument to avoid removal of the gutta percha filling from the canal. The dental assistant ensures that the HVE tip aspirates any smoke and recieves the melted gutta percha from the dentist with a 2x2 gauze.

The dental assistant dries the tooth and passes the articulating paper to the dentist who will ask the patient to lightly tap the teeth together. If necessary, the dentist will adjust the occlusion with the Woodson, cotton applicator or a round bur and slow-speed handpiece.
