Knowledge, attitude, and behavior of Turkish dentists about radiation protection and radiation safety

Objectives: Dentists use dental imaging methods frequently in the diagnosis and treatment of dental diseases. This study aimed to determine dentists' knowledge, attitudes, and behaviors about radiation protection during dental imaging procedures. Methods: Dentists from two major dental health centres in Izmir province were asked to participate in this study. The participants replied to a questionnaire that consisted of questions on the use of radiographic devices, knowledge on the radiation protection of patients and staff, and attitudes and behaviors regarding radiation protection. The questionnaire also included questions about the socio- demographic characteristics of the participants. Descriptive statistics of data were performed using the SPSS software program. Results: Sixty- six dentists participated in the survey. The mean knowledge score of dentists on dental imaging, radiation, and radiation protection was 8.3 +/- 2.6 out of 17, while the mean attitude and behavior score was 8.3 +/- 2.1 out of 27.97% of the participants stated that medical imaging technicians should carry out imaging procedures. The use of rectangular collimators was 9.1%, and using E/F film was 56.3% among dentists. 23.3% of participants stated that they applied the bisecting angle technique during dental imaging, 23.8% stated that they wear a lead apron during imaging, and 37.8% stated that they always used thyroid shields on the patients. In addition, 37.2% of the dentists stated that the patient holds the film during preapical radiography, and 81.5% used the same imaging parameters for adult and pediatric patients. 62% of dentists stated that they question the pregnancy of female patients before imaging. Conclusion: Findings of the study suggest that the knowledge of dentists about dental imaging procedures and radiation protection needs to be improved. The implementation and the follow- up of quality training programs in accordance with the standards set by the national authority will be of great importance.
