O estudo da distribuição dos aparelhos de raios x odontológicos no estado do Piauí

With the discovery of type X ionizing radiation, it became possible to improve studies in both medicine and dentistry. The first dental radiograph was performed 14 days after the discovery, which influenced Edmund Kells in his studies of positioning and techniques, making him the martyr of Dental Radiology. Since then, panoramic and tomographic equipment have evolved, reducing radiation dose, time and improving image quality. The present work aimed to study and analyze the distribution of dental radiology equipment by mesoregions in the State of Piauí, verifying if the distribution complies with Ordinance GM/MS 1.101. Through a descriptive, exploratory and bibliographic study, data were obtained from the CNES website, referring to the distribution of equipment, its use and the history of dental radiology and devices. Based on this, we observed the difference in distribution in Brazilian states, such as in Piauí, the amount of equipment registered by the SUS and private clinics and the arithmetic mean of the use of these devices. It is concluded that, even with the low number of dental X-ray equipment in use when compared to the distribution of other states, some cities in Piauí do not obey the GM/MS Ordinance No. lack of equipment in cities with large population.
