What is the typical range of kVp used for dental x-rays?

The correct range of kilovoltage peak (kVp) for dental x-rays typically falls between 50 to 70 kVp. This range is often selected to ensure adequate penetration of x-rays through the dental structures while maintaining image quality. The chosen kVp affects the contrast and exposure of the dental radiographs, with lower kVp settings resulting in higher contrast images which can be particularly useful for detecting caries and other dental pathologies.

While 40 to 60 kVp may not provide sufficient penetration for certain diagnostic needs, and higher ranges, such as 65 to 100 kVp and 80 to 110 kVp, can lead to unnecessary exposure and lower contrast in dental images, the 50 to 70 kVp range strikes a balance between image quality and patient safety, making it the standard for routine dental radiography.
