Determining endo working length is one of the most complex and important steps in any root canal treatment. Successful treatment depends on being able to find the true working length. For every millimetre short the estimation, the chances of a successful outcome lessen. Electronic apex locators are far more accurate than radiographs and are now an essential piece of endodontic equipment.

The Game Changer - Inbuilt Apex Locators

Up until now, electronic apex locators have mostly only been available as compact standalone units. While accurate and easy to use, these systems are limited in that they require the dentist to switch between devices during treatment. To eliminate the need for switching and reduce operation time for dentists, the new Optima E+ Endodontic motor from B.A. International comes with an integrated apex locator.

How Does it Work?

The Optima E+ uses an innovative inbuilt apex locator to get a highly accurate reading of the working length of a canal space. It does this using the same science as all other electronic apex locators, relying on the body to complete an electrical circuit. The tool has real-time display of file location in the canal and automatic or auto-stop functions for when the file reaches the apical stop to prevent perforation. As with other apex locators, working length is indicated with a reading of 0 on the display. The unit also works as a standalone apex locator using its EAL setting (in which the motor does not run). This can be selected via the motor’s control system.

What are the Other Benefits of the Optima E+?

Along with its built-in apex locator, the Optima E+ comes with several other advantages that make it capable of enhancing endodontic work. One other big advantage is its advanced reciprocation feature (Safety Glide Path mode), whereby the forward angle must be equal to the reverse angle. The adjustment range is from 20° – 340° at 10° intervals. Because the Optima E+ is brushless motor it provides low noise levels (starting at maximum 38.5db, averaging 37.2db for 300RPM), making it one of the quietest motors currently on the market. The brushless motor also improves cutting efficiency and reduces risk of instrument separation.
