Comparative Study of Three Different Techniques for Removal of Broken Instrument
Mennattullah Mohsen Hafez;
Abstract
The future of endodontics is bright and the demand for
initial treatment and retreatment will grow significantly in the
years immediately ahead. As we have seen a variety of techniques
exist to address endodontically failing teeth with foreign body
fragments. However, not all failures are amenable to successful
non surgical retreatment. Clinicians need to weigh risk versus
benefit and recognize that, at times, a referral, surgery or
extraction might be in the patient's best interest. Interdisciplinary
excellence is the foundation for professional fulfillment, patient
satisfaction and long-term success. As the health of the
attachment apparatus around endodontically treated teeth
becomes fully appreciated, the naturally retained root will be
recognized as the ultimate dental implant. Properly performed
endodontic treatment is the cornerstone of restorative and
reconstructive dentistry.
Many techniques, methods and instruments have been
proposed for the removal of root canal obstructions like foreign
bodies, broken instruments, silver cones and cemented posts in
root canals. Many studies have been carried out on all these
techniques and devices and mainly the Ultrasonics proved
efficient.
As seen in this study, Ultrasonics carries all the future for
endodontic treatment. They proved 100% effective in removal of
any canal obstruction. While, others are regressing and proved in

efficient as iRS. Others are still under laboratory study as the use
of chloroform dipped gutta percha cone for removal of broken
fragments.
Removal of broken fragment from curved canals is way
more difficult than their retrieval from straight and wide canals.
Enhanced vision using dental operating microscope is of
major importance for successful retrieval especially with short
fragments separated at the apical one third as seeing them with
direct vision without magnification seems impossible.
Dentin thickness and the conservation of tooth structure
and its restorability are of prime importance when taking a
decision in choosing the system for retrieval of canal obstruction.
CBCT proved more efficient and accurate than normal and
digital radiography, being reproducible and consistent in
recording changes in root canals
