Locating Isthmus Areas

Ultrasonics makes locating and cleaning Isthmus precise.

Failing to locate and treat canal anatomy can contribute to persistent infection and postoperative sequelae. Isthmuses are narrow anatomic areas that connect two root canals. Vital or necrotic pulp can remain in an isthmus if left untreated. However, instrumentation of an isthmus with burs can result in excessive removal of tooth structure and iatrogenic ramifications. The concomitant use of ultrasonics and magnification facilitates precise and selective cleaning of isthmus areas.


E2D – Conical Diamond

The E2D – Conical Diamond is indicated for both side and end cutting, enlarging the ishtmus and troughing.

  Ideal 20% Max 30%


E6D – Pear Diamond

The E6D – Pear Diamond has excellent durability. It is used to locate canals, remove coronal obstructions, calcifications, restorative materials, cements (permanent and temporary), etc. The tip creates a smooth, flat, clean troughing groove that eases canal location. It can also be used to refine prep margins and box preps, and to remove caries.
