[Use of the TRI AUTO ZX instrument in clinical endodontics]

The aim of this study was to test the clinical reliability and applicability of TRI AUTO ZX (TAZX) instrument for working length determination and shaping as well as widening of root canals. Thirty teeth were treated by the means of TAZX instruments. A close correlation was found between working length data obtained by TAZX instrument and by conventional radiography. Using TAZX no failure (file separation, apical foramen transposition, etc.) was observed. According to our experiences TRAZX instrument seems to be a valuable tool for endodontic procedures.
