Cone Beam Computed Tomography offers highly precise 3D images ideal for diagnosis and case planning, although this imaging method involves the use of high doses of radiation. When considering the optimization principle, radiation dose reduction methods aim to modify the technical parameters of the equipment to obtain an ideal combination between dose and image quality. This is important in the pediatric patient because the highest levels of risk are associated with X-ray exposure in this age group. We present the case of an 11-year-old female patient is presented, in which a low-resolution protocol is used to locate the maxillary retained canines. The advantages and practical application of this imaging study method are analyzed by performing variations in exposure parameters. Supported by tomographic images, the surgical procedure is carried out to subsequently a guided eruption, achiev...
