چکیده
Successful root canal treatment depends upon the accurate determination of canal length to achieve adequate biomechanical preparation of canal .The generally accepted method for working length determination, is radiographicmethod .Use of electronic divices for working length determination has recently gained considerable popularity among both general dentists and endodontists. The aim of this study was to compare the accuracy of two apex locators (made in Iran) which were from first generation. A set of 28 single root teeth with one canal was gathered for study. At first, the actual root canal length was determined with placing a file into the canal so that the file tip was seen at the apical foramen. Then, the teeth were placed in the experimental model containing buffered phosphate saline with 1% agar to the cervical area and fixed in that position. The root canal length of these teeth were determined using the DMG and Foramatron V Apex locators in dry and wet conditions and the data were registered. The results of this study showed that Foramatron V accuracy in length determination in dry condition was 75% (21samples) and 71.4% (20 samples) in wet condition. DMG accuracy in dry condition was 64.2% (18samples) and 53.6% (15 samples) in wet condition. There were no significant statistical differences between actual length mean and length mean evaluated by DMG and Foramatron V apex locators in dry and wet conditions. we concludedthat electronic apex locators could be a useful adjacent for determining the working length of root canal.Keywords: Apex locator, Working length, Apical foramen
