Another Effort Though I failed so utterly in my first effort to have anideal pulp tester made of a Faradic machine, the failurewas due entirel^^ to preventable mistakes and such anideal pulp tester, I am promised, is now being producedbv another manufacturer. 30 • ELECTRO-EADIOGRAPHIC DIAGNOSIS The Ionization Machine Equipped with the right kind of a dental electrode(Fig. 14) some ionization machines (Fig. 5) make ade-quate pulp testing machines. An ionization machineshould not be purchased if it is to be used only as apulp testing machine, for a good pulp testing machine ofa different style, say the Faradic type, can be purchased. Fig. 5.—An ionization machine (on dental bracket). at much less expense. If, however, one intends to use, oris using ionization, then the ionization machine may beused as a pulp tester if the current it generates is strongenough. The Dental Switchboard Some dental switchboards are, I understand, now madewith sockets (places for attachment) where a suitablecurrent for pulp testing may be obtained. If the switch- PULP TESTIXG IMACHIXES 31 board lias been built witli the idea of giving tlie operatora pulp testing current, doubtless such a current is avail-able, for dentistr^^ is fortunate in having such reliablemanufacturers of electric equipment. But certainly it isrisky business to tap somewhere into a switch-board, not built especially to deliver a pulp testing orionization current in
