• Do not use an ultrasonic scaler with the contrary electrode attached to the patient. Electrical noise from the
scaler could interfere with canal measurements.
• Make sure that the contrary electrode, file holder etc. do not come into contact with an electric power
source such as an electrical socket. This could result in a severe electrical shock.
• The contrary electrode could cause an adverse reaction if the patient has an allergy to metals. Ask the
patient about this before using the contrary electrode.
• Take care that medicinal solutions such as formalin cresol (FC) or sodium hypochlorite do not get on the
contrary electrode or the file holder. These could cause an adverse reaction such as inflammation.
• Always clip the file holder to the upper part of file shaft, near the handle. The metal and plastic part of the
file holder can be damaged if they are attached to the file’s cutting part or the transition to the cutting part.
