The importance of microsonics concept for optimization of endodontic retreatment outcome: a case report

Resumo

During the past few decades, the endodontic treatment
has benefited from the development of new techniques and devices,
which have improved the outcome and predictability. Important
attributes such as the operating microscope and ultrasonics have
found indispensable applications in a number of dental procedures
in endodontics. Objective and case report: This study describes a
case of endodontic retreatment of a maxillary first molar in which
the second mesiobuccal canal could be located by extending the
access to the mesial direction further than usual and by a closer
inspection of the pulp chamber floor. Conclusion: The “microsonics
concept” has enhanced the quality of endodontic treatment and
retreatment, becoming increasingly more useful in applications such
as localization of root canal orifices.
