Resumo:
Electronic foraminal locators are devices used to measure the length of
of the tooth for endodontic purposes. The present study aimed to analyze the
Joypex 5® electronic foraminal locator performance in human teeth in vitro for
obtaining the actual length of the tooth compared to direct observation. The Joypex
5
® was applied to thirty single-rooted human teeth, having been previously
coronary access of the teeth, followed by exploration with a K-file #10 file until its
extremity be observed at the foraminal outlet with the aid of a magnifying glass of 4
times. The rubber stop was positioned on the incisal edge or cusp tip, measuring
the actual length of the tooth with an endodontic ruler in millimeters. the teeth were
inserted in an experimental base composed of floral sponge soaked in a solution of
0.9% sodium chloride and the canals were irrigated with 5 mL of Milton's solution. At
Electronic measurements were performed having, as a criterion, the location of the apical foramen of

concluded that Joypex 5® proved to be accurate for determining the actual length of the
tooth during endodontic treatment.
