Where is the rheostat (foot control) typically placed in the dental office?

The rheostat, commonly referred to as the foot control, is typically placed on the floor, usually behind the dental chair. This placement allows the dental professional to operate equipment hands-free while maintaining proper posture and movement during procedures.

Having the rheostat on the floor lets the dentist or dental hygienist control the speed and operation of the handpieces and other equipment simply by using their foot. This is especially beneficial during procedures that require both hands for precision, as it enables seamless workflow and reduces the need for the practitioner to divert their attention away from the patient.

Placing the rheostat on the dental chair or the dental tray would limit accessibility and could lead to accidental activation or operational difficulties during treatment. Similarly, positioning it on the treatment cabinet would not provide the same ease of control and accessibility that the foot-operated placement offers during procedures.
