dc.description.abstract | The aim of this study was to evaluate in vivo the clinical applicability of two electronic apex locators (EALs) - Apex (Septodont) and iPex (NSK) - in different groups of human teeth by using radiography. The working lengths (WLs) of 100 root canals were determined electonically. The EAL to be used first was chosen randomly and a K-file was inserted into the root canal until the EAL display indicated the location of the apical constriction (0 mm). The K-file was fixed to the tooth and a periapical radiograph was taken using a radiographic film holder. The K-file was removed and the WL was measured. The same procedure was repeated using the other EAL. Radiographs were examined with the aid of a ligth-box with lens of x4 magnification by two blinded experienced endodontics. The distance between the file tip and the root apex was recorded as follows: (A) + 1 to 0 mm, (B) -0.1 to 0.5 mm, (C) -0.6 to 1 mm, (D)-1.1 to 1.5 mm, and (E) -1.6 mm or greater. For statistical purposes, these scores were divided into 2 subgroups according to the radiographic apex: acceptable (B, C and D) and non-acceptable (A and E). Statistically significant differences were not found between the results of Apex and iPex in terms of acceptable and non-acceptable measurements (P>0.05). Apex and iPex EALs provided reliable measurements for WL determination for endodontic therapy. | en_US |
