Análise de precisão do localizador apical eletrônico joypex 5: estudo in vitro.

Abstract

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 according to the apex marking on the Joypex 5® device. In continuity, the preparation of the cervical third of the teeth with the Gates Glidden drills, repeating the entire procedure. electronic foraminal measurement process. The data showed no differences

significant statistics between measurements obtained by Joypex 5® and direct observation. He can- concluded that Joypex 5® proved to be accurate for determining the actual length of the

tooth during endodontic treatment.
