What is the typical mA range for dental machines?

Dental machines typically operate in the range of 7 to 15 mA. This range is optimal for the imaging requirements of dental radiography, allowing for sufficient exposure to produce clear, diagnostic images while minimizing radiation dose to patients.

Lower mA settings, such as those below 7, may not provide enough image quality for detailed examination of dental structures. Conversely, higher mA settings, particularly those approaching 20 mA or more, could lead to unnecessary radiation exposure without a corresponding benefit to image quality. Thus, 7 to 15 mA strikes a balance between achieving adequate image clarity and ensuring patient safety in dental practices.
