Comparative evaluation of accuracy of two electronic apex.
Comparing the accuracy of four electronic apex locators for determining the minor diameter:. Measurements with electronic apex locators may be inaccurate in the presence of a wide apical foramen and a small size file.24, 28 Herrera et al found that the Root ZX measurements were more accurate when the foramen was 0.25 mm than when the foramen was between 0.45 and 0.70 mm. 24 For this reason.
These apex locators use two frequencies instead of a single one to measure the impedance in order to determine the WL. With this scientific rationale these should be called “comparative impedance” type apex locators. However, the impedance of any given circuit is influenced by the frequency of the current flow, hence the name frequency based apex locators. The credit of being the first.
Many electronic apex locators can give accurate measurements despite fluid conductive like saliva, blood or irrigant. Accuracy can vary between 80% and 96%, which is better than a radiograph. When the maximum length of the root canal is reached, the endodontic apex locator will signal via beep, buzz, flashing light or all of the above. Some show an image of the tooth with the root canal.
In vitro comparison of two electronic apex locators Brochado, V. H. D.; Ramos, C.A. S.; Prescinotti, R.; March 2010 - 2 - indicated reliable and precise measurements of the position of apical foramen. The presented positive results were shown superiors to the of the INGLE radiographic technique. The present study intends to identify if the new Romiapex A-15 and Root ZX II presents necessary.
Aim: Comparison of the effect of QMix, 7% maleic acid and 2.5% sodium hypochlorite on the accuracy of Root ZX II and Root ZX Mini apex locator. Methodology: 45 single rooted teeth were decoronated. Patency was checked and coronal flaring was done. They were then divided into 3 groups: i) QMix, ii) 7% Maleic acid and iii) 2.5% Sodium hypochlorite.
This is commonly achieved using an apex locator which is influenced by the presence or absence of the apical constriction. Hence, this study was done to compare the accuracy of two generations of apex locators in teeth with simulated apical root resorption. Materials and Methods: Forty maxillary central incisors were selected and after access preparation, were embedded in an alginate mold. On.
Recently, electronic apex locators are being used to determine working length and decrease the number of radiographs. The purpose of this study was to compare the sensitivity of Root ZX and Novapex electronic apex locators with radiography in a clinical study. Materials and Methods: In this study, 73 single-canalled teeth of the patients referred to the endodontic department of the Yazd Dental.
