Apex Locator - Booster to Dentist : Literature Review

Abstract

<jats:p>Successful root canal treatment depends on thorough cleaning &amp; shaping and 3- dimensional fluid impervious obturation of tooth within the confines of canals. To achieve this objective the apical constriction must be detected accurately during canal preparation and precise control over working length during the procedure must be maintained. There are many methods of working length determination including radigraphs and electronic method(apex locator). Introduction of apex locators have definitely served as an effective adjuvant to radiographs. </jats:p>

Accuracy of Three Types of Apex Locators versus Digital Periapical Radiography for Working Length Determination in Maxillary Premolars: An In Vitro Study

“…The apex locator is another commonly used instrument for WL determination. The recent advances in apex locators have enabled more accurate and predictable estimation of WL [ 7 ]. Apex locators can find the location of apical constriction, which is the most suitable location for termination of root canal instrumentation [ 7 ].…”

“…The recent advances in apex locators have enabled more accurate and predictable estimation of WL [ 7 ]. Apex locators can find the location of apical constriction, which is the most suitable location for termination of root canal instrumentation [ 7 ]. A meta-analysis evaluated four generations of apex locators and reported that all generations were accurate enough for measurement of WL, and generation of apex locators had no significant effect on their accuracy [ 8 ].…”
