In the dental community, the main concern concerns the effects of dental radiation on children. Panoramic dental x-rays can cause DNA damage and cell death in the oral mucosa cells of these children. The cone beam scanner, which was considered the safest, is harmful to children because they are more sensitive to the effects of radiation. Children are far more sensitive to changes in their cells from a given dose of radiation than adults because they continue to grow, develop and change. Radiation protection is necessary to protect all children and adults from exposure, the lower the exposure, the fewer problems there will be later in life. Children are more sensitive to changes in their cells if they receive adult doses of radiation. The main risks of these tests for children are an increased risk of developing cancer and changes to their genes later in life. A study was carried out in Brazil at the Metodista University of Sao Paulo, with 17 healthy children. 8 of the children were boys and 9 of them were girls, aged approximately 7 years, who had undergone outpatient panoramic dental radiographs at the pediatric department. All panoramic dental radiographs were ordered and performed by the dentist. This study was approved by the UMESP Human Ethics Committee. Before X-ray exposure, oral mucosa was collected, and then 10 days after X-ray exposure, it was collected again. Once oral mucosa was collected after X-ray exposure, radiation levels were tested, showing very little change in effect. The statistics from this study are that before exposure, 17 children had micronucleated cells of 0.04 to 0.06 and after exposure to x-rays, there were 0.05 to 0.06 micronucleated cells. Very little change was seen... middle of paper ...... when the parameters were set to the pediatric level, as they should be. Shielding is one of the most important things you can do to protect any patient from radiation exposure. The lead vest, the lead collars, the radiation settings tailored to each patient rather than a random setting, and the abilities as a dental assistant to be competent enough to take all the x-rays the first time without need to expose your patient. on several occasions.Bibliography (nd).Aker, M.
