Endodontics – Conventional Treatment
 Cleaning and Shaping the Canal System
After administration of a local anesthetic, a protective sheet called a rubber dam is placed on the tooth to isolate it and keep it free of mouth contaminants.
An opening is made in the crown of the tooth and the canal openings are explored for number and size. Small specialized instruments (called files) are inserted into the canals and an electronic device (apex locator) is used to measure the exact length. This is then confirmed with an X ray image. This Working Length, is critical to the success of treatment.
The canal system is cleaned and shaped by sequential application of larger instruments until desired shape is achieved. With the use of special irrigating solutions, the shaping of the canal system also allows for easier cleaning. The cleaned canal system is now ready for filling.
