Sixth Generation Adaptive Apex Locator
نویسنده
چکیده
A comparative analysis is made which is grounded on literary data concerning the advantages and disadvantages of apex locators of various generations that have been created following two different principles /19, 28/. The PURPOSE of this study is to create a method and a device that combine the established advantages of fourth and fifth generation instruments. While measuring the working length of the root canals of 30 extracted human teeth /dry and filled with animal blood and sodium hypochlorite/, experimental research work was carried out which has served as a basis for creating both a method and an adaptive apex locator that combine the advantages of the two previous generations of appliances. The prolonged direct and juxtaposing studies have made it possible to create a steady algorithm for adapting the method for measuring the working length of the root canal depending on the canal’s moisture characteristics. The method has been implemented in the apex locator of the so called sixth generation – the adaptive type. Measurement with the adaptive apex locator has made it possible to eliminate the necessity of drying or moistening of the canal, as well as to achieve high degree of measurement precision in the presence of blood, of additionally imported liquid /sodium hypochlorite/, or while manipulating dry canals. Clinical observations are yet to come that will help assess the device’s ability to determine the working length of root canals under various clinical conditions and situations.

Evaluation of the Use of Sixth Generation Apex Locators as a Diagnostic Tool to Detect Root Perforations
Aim: The sixth generation apex locators served as an efficient diagnostic tool for detecting root perforations as these are based on the principle of impedance rather than the conventional gradient method. However, their diagnostic accuracy not evaluated well. In the existing study, we assessed and compared the efficacy of two apex locators for diagnostic perspective. Materials and Methods: A t...

Comparison of Working Length Determination Using Apex Locator and Conventional Radiography in Curved Canals-an In Vitro Study
Introduction: The exact measurement of the root canal length is of great importance in root canal therapy. Although, determination of the root canal length through radiography is the most common method, 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 accuracy of an electronic apex l...
