With some types of the high-frequency X-ray coil (Fig. 360) theoperator has at his disposal the high-frequency current for electro-therapeutic work. The value of the high-frequency current as a therapeutic agent in thepractice of dentistry has not been satisfactorily established. I would.

Some coils are so constructed that the coil proper may be placed ona shelf on the wall, up out of the way, the controls of the coils or switch-board being mounted elsewhere and within easy reach. With an X-raymachine installed in this way overhead wiring is usually necessary. The principle of the overhead wiring system is illustrated in Fig. terminals of the coil are attached to the overhead wires. On the X-RAY MACHINES 3^3
