title: [Electronic apex localizers: useful instruments or inconvenient gadgets?].
abstract: Apex locators offer definite advantages for certain patients over conventional radiographic methods of root canal length measurement. Current instruments do not appear to differ significantly in accuracy. The choice of locator has to be made therefore on cost and convenience in use. The current best buys seem to be the Evident RCM and NeoSono MC. Both offer good value for money, the Evident is the less expensive but lacks some of the additional features of the NeoSono. The decision to buy an apex locator should only be made after a period of testing in clinical practice.
