Controle de qualidade para análise do desempenho de um equipamento de raios X odontológico intraoral

Abstract

Quality control in X-rays is of fundamental importance to ensure the proper functioning of the equipment. Properly functioning equipment guarantees the quality of the images produced and the safety of patients, professionals, students, and teachers. Although not mandatory for educational equipment, it is ideal that quality control is performed, ensuring safety for those handling the device and providing better quality of education. The objective of this study is to verify whether the operation of a professional intraoral dental X-ray device used for teaching purposes at a university complies with ANVISA’s normative instruction No. 95, of May 27, 2021. Of the fifteen tests described in Normative Instruction No. 95, eight were performed, namely: half-value layer, tube voltage accuracy, exposure time accuracy, representative dose value, linearity and reproducibility of air kerma, field size, and focus-to-skin distance. Most tests yielded adequate results, while some were above the tolerance level, not exceeding the restriction level. It was concluded that the device remains in conditions to be used for academic purposes, not requiring immediate maintenance, as current legislation does not apply to equipment intended for this purpose.
