A metallic obstruction in the canal orifice of a maxillary right canine could not
be bypassed during endodontic treatment. Aids such as ultrasonics and retrieval
kits were not available for the removal of the obstruction. Therefore, a novel
approach using a disposable syringe needle was employed. A 22-gauge needle was
inserted into the orifice and turned in an arc with a gentle apical pressure and
alternate rocking motion around the obstruction. This procedure was repeated few
times to cut dentin and successfully dislodge and remove the obstruction using
the sharp beveled tip of the needle. This case report demonstrates that, in the
absence of other aids, the use of a disposable syringe needle is a simple,
economical, and yet an effective technique for conservative removal of dentin and
to dislodge and remove an obstruction from the root canal. However, its
effectiveness depends on case selection and straight-line accessibility to the
obstruction.
