Working length estimation made more convenient

Working length estimation made more convenient

The determination of working length in endodontics is one of the most complex and important steps in root canal treatment. Even the most experienced dentists can find it challenging.

Chances of successful endo treatment decrease with every mm a dentist or endodontist comes up short of the true working length.

The introduction several years ago of impedance-based electronic apex locators has helped make life easier for dental practitioners. Modern apex locators are relied on to deliver up to 97% accuracy.

An electronic apex locator is a more accurate way of identifying the apical foramen over traditional x-rays or hand files. It is an essential part of most dentist’s endo kit.

New innovation

Up until now, electronic apex locators have mostly only been available as compact standalone units.

While these systems are easy to use and can provide exceptional accuracy, one limitation is that they require the dentist to switch between devices.

The new Optima E+ endodontic motor from B.A. International comes with an integrated apex locator that removes this weakness and reduces operation time for the dentist.

This can add some much-needed convivence to complex root canal treatment and negate the need for separate apex locator and rotary handpiece purchases.

What’s special about the Optima E+?

The Optima E+ uses an innovative built-in apex locator to get a highly accurate reading of the working length of a canal space.

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.

The unit also works as a standalone apex locator using its EAL setting (in which the motor does not run). This is selected via the motor’s control system.

How do apex locators work?

The apex locator built into the BA Optima E+ relies on the same science as all other electronic apex locators.

It works by using the body to complete an electrical circuit. There is a lip click connection to the oral mucosa and a connection to the endodontic file.

The electrical circuit is completed when the instrument is inserted into the root canal in the apical direction and touches the periodontal tissues.

Electronic apex locators indicate this point has been reached by displaying a reading of 0. This point is considered the true working length.

Other advantages of electronic apex locators

  • Deliver up to 97% accuracy
  • More accurate than radiographs
  • Less likely to damage apical constriction compared to manual methods
  • Speed up treatment time
  • Less patient exposure to radiation
  • Can detect perforation.

What are the other benefits of the Optima E+?

Along with its built-in apex locator, the Optima E+ comes with several other plus points capable of enhancing endodontic work.
One other big advantage is its advanced reciprocation feature, whereby the forward angle must be equal to the reverse angle. The adjustment range is from 20° – 340° at 10° intervals.

This feature is available using the Safety Glide Path. It allows dentists even greater flexibility.

Other notable benefits include:

  • One of the quietest motors on the market (average 37.2db for 300RPM)
  • Brushless motor improves cutting efficiency and reduces risk of fracture
  • 32 inbuilt endo system pre-sets, including for Edgeendo
  • 10 customisable memory programs
  • 360° rotatable 6:1 contract-angle head
  • Auto start and stop functions
  • Adaptive Torque Reverse mode
  • Dominant hand use option
  • Easy to read OLED display
  • Long-life 2000mAh lithium battery
  • Wireless charging.
