Desenvolvimento de objeto simulador para medir campo de radiação em raios x odontológico convencional

Abstract

In dentistry radiography is of fundamental importance so that we can make an accurate diagnosis. For this it is necessary to give due attention to radiological protection of both the professional and the patient and both the quality of image and quality control control of X-ray machines, all in order to do a proper examination without expose the patient to higher doses than required for diagnosis. It is very important to do the quality control of dental X-ray equipment, because in recent years this type of service has been increasing in Brazil and people are being increasingly exposed to this type of radiation. In this paper quality control tests were performed in dental intraoral X-ray machines in 11 private offices in the city of Marabá, where were the diameters of the radiation field measured to assess whether they are within the Order 453/98 of the Ministry of Health standards and thereby avoiding that the patient is exposed to the radiation field higher than necessary for diagnosis. The results of X-ray equipment will be studied and evaluated, and so we created a phantom to measure the size of the intraoral dental X rivers radiation field, where it is analyzed the diameter of each device radiation field and assess whether they are of as recommended. Before this study it was observed that the city of Marabá need a Quality Control Assurance Program of dental x-ray equipment to perform quality control equipment, ensure the radiological protection of patients and professionals and still hold control quality images, and for that the city requires specialized professionals in this type of control and also help them dentists and their assistants to perform the dental radiology services in accordance with the recommendations of ANVISA.
