After unsuccessful attempts to bypass the file, trephining was done by with using K-files ISO size 6, 8, 10, 15 and Anatomic variations can significantly contribute to the incidence of endodontic mishaps.

Endodontic mishaps: etiology, prevention, and management.

They should be cautiously used in approximation to the obstruction and care should be ensured to use them away from the furcation. Different materials have been used for the nonsurgical repair of perforations with varying degrees of success. An analysis based on clinical, roentgenographic and histological findings.


Maintaining the integrity of natural dentition is essential for fully functional and esthetic conditions. Diagnosis and treatment of accidental root perforations.

Middle and apical thirds were prepared, and this was followed by apical gauging using hand instruments — nickel-titanium NiTiFlex files[ 22 ] — during which the separation of size 30 file occurred in the extra root RE.

A crown-down pressureless preparation root canal endodontlc technique. Master cone selection radiograph evidencing successful removal of separated instrument.

Perforations and separated instruments form the bulk of such mishaps. The sealing ability of mineral trioxide aggregate as a retrograde root end filling material. Ideally, radicular access should be performed in a way that the canal is pre-enlarged and shaped to the same diameter as that if there was no broken instrument obstructing the canal. However, the best antidote for a broken file is prevention. The canals were debrided and disinfected using copious amounts of 2.

Endodontic mishaps: etiology, prevention, and management.

Refinements in endodontic cavity preparation and radicular inclinations should be given due considerations in teeth presenting anatomical variations such as radix entomolaris so as to prevent procedural accidents during various endodontic and restorative procedures.

Evaluation of an ultrasonic technique to remove fractured rotary nickel titanium endodontic instruments from root canals: An additional third root, first mentioned in the literature by Carabelli is called radix entomolaris RE. Retreatment of nonhealing endodontic therapy and management of mishaps.

Nil Endodontci of Interest: On a follow up examination after 15 days, 1 month and 2 months, satisfactory healing was evident both clinically and radiographically. The presence of RE was evident on the working length radiograph [ Figure 4 ]. The canals were negotiated and hemostasis was achieved using calcium hydroxide.

Special attention should be directed towards flaring the axial wall that approximates the canal holding the broken instrument in efforts to subsequently improve the micro-sonic techniques below the orifice.
