Abstract: An instrument, especially useful in the field of dentistry by virtue of its shape, size, and construction, adapted for example for severing ends from threaded retention pins which have been inserted intra-coronally in natural teeth to aid in retentively adhering tooth restoration material to a tooth being repaired, and operable subsequent to such severance to positively contain a severed end for facile removal thereof from a patient's mouth. The instrument has additional uses in, as one example, the field of intra-oral surgery of a type that includes utilization of wire arch bars in a procedure to immobilize a patient's jaws, where jaw fracture exists, and after placement and affixation, wire ends can be severed and retained by the instrument for removal from the mouth of the patient. The instrument can also be used in the field of orthodontics to, for example, trim or cut wire ends and remove the so-severed wire ends.
