CASTRO, Maurício Augusto Aquino de et al. Evaluation of the use of x-ray equipment in dental offices in Belo Horizonte, Brazil. Arq. Odontol. [online]. 2013, vol.49, n.4, pp. 191-197. ISSN 1516-0939.

Aim: To evaluate the theoretical and practical radiological knowledge of dentists in the city of Belo Horizonte, Brazil. Materials and methods: A questionnaire was applied to 256 randomly selected, registered dentists in Belo Horizonte, focusing on aspects related to theoretical knowledge and radiologic practice. Data were analyzed using frequency and bivariate analyses. Results: Of the respondents, 53.9% had x-ray equipment. Of these, 19.6% did not know what type of device they used. Professionals who had graduated up to 20 years prior showed a greater knowledge about radiographic techniques, the procedures of radioprotection, and biosafety, but showed less knowledge about the characteristics of the instruments they used. On other hand, trained professionals who had graduated more than 21 years prior, demonstrated greater knowledge about the equipment and less knowledge in relation to radiographic techniques, radioprotection, and biosafety. The portable developing chamber proved to be the most widely used processing environment. Conclusion: It could be observed that radiological practice presents specific problems, suggesting the need for improvements in both professional training and post-graduate studies.
