Dagleish2 used a curved indentor which creates a clearly seen indentation. Strampelli3 used a transilluminator with a diathermy wire beside its tip.

Instrument  In the instrument to be described,* the diathermy current is conducted along a wire electrode which runs through the center of a transilluminating glass applicator (Fig 1).The instrument (Fig 2) consists of a handle containing a small light, a conductor for diathermy current, and a control switch.
