A Questionnaire of Digital Radiography and CBCT Use and Knowledge among Lithuanian Dentists

OBJECTIVES: Digital radiography is an increasingly used technology in Lithuania. However, there is no published information about using cone-beam computed tomography. The aims of this cross-sectional study performed in Lithuania were (1) to obtain information about the prevalence and accessibility of digital radiography and cone-beam computed tomography usage, and (2) to estimate dental practitioners’ knowledge about this diagnostic method and their need for education. MATERIAL AND METHODS: Questionnaires consisting of 31 questions were distributed during the 2019 International Dentist Congress in Lithuania. RESULTS: This study analyses the data obtained from 248 respondents. Most of the clinicians use digital radiographic methods in their practice. The institutions usually have a digital dental X-ray machine, less often a digital panoramic X-ray machine, and least often a cone-beam computed tomography (CBCT) unit. Most dental practitioners performed 1 to 10 CBCT scans per month for adult patients and the most frequent reason for its use was implantation planning. Of the practitioners, 81.7% would like to improve their CBCT knowledge and skills. CONCLUSIONS: The number of digital X-ray machines has increased throughout the last decade. Lithuanian dental practitioners do not excessively use cone-beam computed tomography. Some concerns were raised regarding respondents’ knowledge about exposure factors and this diagnostic method’s performance for paediatric patients. Additional training should be provided to Lithuanian dental specialists.
