ROOT CANAL TREATMENT

The stigmata of fear and pain are fast disappearing root, a small device is inserted into the wound, and a cavity is cut into the exposed dentine in the root. As much dentine as
possible is removed, and the root canal is then plugged with a filling material, which fills
the canal and seals the end of the root. The operation is performed strictly under aseptic conditions.
At a time when successful outcome in endodontics has vastly improved, and the stigma of painful root canal therapy is disappearing,treatment time has also been shortened.
