The Endo Safe End instruments are available in 2 sizes
(1.4mm and 1.8mm) and are designed for lateral endodontic access
enlargement without the risk of penetrating the pup chamber floor.
The safe end tip will prohibit the access from getting
deeper but will allow for lateral expansion.
Adequate access is essential for successful endodontic
treatment. A straight line to the canal system is optimal. Without
adequate access, instruments and materials become difficult to handle
properly in the complex root canal system. The end result of proper access
cavity preparation should consist of the following:
Achieve straight-line access to the apical
foramen or to the initial curvature of the canal
Locate all root canal openings
Conservation of healthy tooth structure
1. Initial Endodontic Access
Use appropriate sized round carbide operative burs (FG #4,
FG #6 etc.) or appropriate sized Great White® round burs (both
standard and surgical length shanks available) to access the metal coping
If endo access is through a PFM
crown, penetrate the porcelain with a round diamond and then switch to a
Great White® round bur to access the metal coping material.
2. Enlargement of Endo Access to Gain
Straight Line Access to All Canals
This must be accomplished without penetrating the
floor of the pulp chamber.
The Endo Safe End instrument will cut only laterally and
not apically to prevent perforation of the furcation area.
The ideal bur for this procedure would be side-cutting
only with a safe end (non-cutting) tip designed to prevent ledging the SS White® Endo Safe End burs.
