DemPex™ Apex Locator is a convenient hand-held, precise, portable and user-friendly electronic device for use in root canal treatments.

Fitting snugly in the hand, this instrument helps the dental practitioner to perform the endodontic procedure with greater confidence, speed and safety.

It enables highly accurate determination of the position of the apical foramen in wet and dry canals.

It determines the precise working length of the root canal.

DemPex™ is powered by a single AAA 1.5V alkaline battery. It uses the frequency-impedance method, and proprietary algorithms to locate the apical foramen.
