Device Description
The Digitest II™ Pulp Vitality Tester is a hand-held,
battery-powered dental diagnostic device that
identifies a living tooth nerve by stimulating it with a
weak electric current. When the operator depresses
the button, the strength of the electrical stimulus
automatically increases at a rate preset by the
operator. The unique waveform is designed to trigger
a patient response in a vital nerve with a minimal
amount of discomfort.
Intended use/indications
The Digitest II Pulp Vitality Tester is intended to
be used as a diagnostic instrument to assist in the
determination of the vitality of the dental pulp.
Contraindications
This device is contraindicated for use on a patient
or by an operator wearing a cardiac pacemaker
or any other intra-corporeal electronic device
(internal defibrillator, insulin pump, etc.), or any
personal electronic monitoring device.
Warning

violate safety codes, endanger the patient
and the operator, and void the warranty.

dental professionals qualified in the use of
the unit.
