New electronic metal locator.

An in vivo evaluation of Root ZX electronic apex locator.

The Root ZX has been introduced recently as a device capable of performing accurately in the presence of sodium hypochlorite, blood, water, local anesthetic, and pulpal tissues. The Root ZX was used to locate the apical foramen in 26 root canals of vital teeth. After extraction of the teeth, a stereomicroscope was used to confirm visually the relationship of the tip of the endodontic file to th...

Tooth embedding medium influences the accuracy of electronic apex locator.

This study evaluated the influence of tooth embedding media on the accuracy ofan electronic apex locator. The root canal length of 20 human mandibular canines was measured by inserting a 15 K-file into the root canal up to the apical foramen. The distance was measured with a digital caliper. The embedding media evaluated were alginate, saline, floral foam or gauze soaked in saline. Electronic r...

ارزیابی دقت Electronic apex locator (EAL) در تعیین طول کانال دندانهای شیری تحلیل رفته در آزمایشگاه

ارزیابی دقت یک نوع Electronic Apex Locator  در تعیین طول دندانهای شیری (In-vitro)

Statement of Problem: Radiography is the most common technique in working length determination, however, because of its limitations is not considered as an ideal technique. Its application, particularly for children due to radiation hazards, technical problems in young and unco-operative children and the superimposition of permanent teeth bud on primary teeth root, lead to numerous problems.Pur...

Evaluation of Two New Electronic Apex-Locator-Controlled Handpieces Using a NiTi Rotary File: An In Vitro Study

OBJECTIVES The aim of this in-vitro study was to compare the accuracy of two new electronic apex-locator controlled handpieces (EALHs) using the first rotary Mtwo file while rotating in the canal. MATERIALS AND METHODS A total of 36 extracted mandibular molar teeth were selected. The lengths of the mesio-buccal canals to the major foramina were measured directly using a size 10 K-file introdu...
