The multi frequency apex locator eliminating necessity of drying the canal and improve precision and accuracy in reading the working length.It provides with a digital read out, graphic illustration and an audible signal.Modern technology, professional service, and an eye on developments in endodontic advancements: we do everything to ensure your teeth get expert treatment. The picture shows an Electronic Apex Locator with Multi frequency. From resistance type in 1st generation, impedance type in 2nd generation the frequency type in 3rd generation, nowadays the latest generation of electronic apex locators are using multi frequency to be more precise and accurate. The development of apex locator has evolved since its first generation to now the 6th generation of apex locator. As the file touches the soft tissues of the periodontal membrane, the electrical resistance gauges for both oral mucosa and periodontal membrane would have similar readings and the length of the canal can be determined here. The attached file is slowly inserted into the root canal up to the estimated working length. Other end is termed as 'file holder' which is a probe attached to the endodontic instrument in use. One end is called 'lip hook' which is placed in contact with the oral mucosa of the patient. An electronic apex locator cord has two ends. The work of an Apex Locator is determined by comparing the electrical impedence of periodontal membrane with that of the oral mucosa. An electronic apex locator has been shown in Fig.6. Precise name of electronic apex locator (EAL) is Electronic Root Canal Length Measurement Device (ERCLMD) or Electronic Canal Length Measuring Devices. The development of the electronic apex locator has helped make the assessment of working length more accurate and predictable.Īpex locator is an electronic device used to determine the position of the apical foramen and its location and thus determine the length of the root canal space. Nowadays, the use of an electronic method to determine working length using an apex locator have proven to be powerful and useful adjunct. And this level of CDJ is the same with the level of apical constriction. Therefore, we should stop our root canal preparation at the point of CDJ. ![]() The cementodentinal junction (CDJ) is the anatomical and histological landmark where the periodontal ligament begins and the pulp ends. Grove (1930) stated that the proper point to which root canals should end is the junction of the dentin and the cementum and that the pulp should be severed at the point of its union with the periodontal membrane. The position of radiographic apex may/may not be the same with apical foramen, but the position of apical foramen will not be the same with apical constriction. Apical Constriction: The narrowest point of the canal.Apical Foramen: The point where the neurovascular bundle enters the root apex.Radiographic apex: The highest point or tip of the root as seen on the x-ray.There are three area that can be considered as the proper point of the terminus of root canal system. Before we proceed with how to determine this length, we need to understand where is the proper point that the root canal systems end. This can only be achieved if the length of the tooth and the root canal is determined with accuracy. And we need to make sure that these procedures should be confined within the root canal systems. The outcome of endodontic treatment is influenced significantly by removal of all pulp tissue, necrotic material and microorganisms from the root canal systems. ![]() ![]() But nowadays an electronic method using an apex locators have definitely served as an effective adjuvant to radiographs. The radiographs are one of the traditional methods for determination of root canal length. There are many methods of working length determination. 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. Successful endodontic treatment depends on the triad of shaping, thorough cleaning and 3- dimensional obturation of tooth within the confines of canals.
