Abstract: A dose-reducing x-ray aiming device includes an aiming ring having shield with an aperture, at least one arm, and at least one sensor holder. The dose-reducing x-ray aiming ring is generally used to aim a dental x-ray machine and at least partially shield some of the x-rays emitted from the x-ray machine while capturing radiographs. X-rays generally pass through the aperture and then interact with a sensor for capturing the radiographs after passing through the tissue of a patient. In one embodiment, the x-ray aiming device provides an all-in-one aiming ring, which allows a user to capture both periapical and bitewing radiographs with a single device. The aiming device also includes an annular ridge or lip which helps align the x-ray machine with the aiming device.
