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

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.

Questionnaires consisting of 31 questions were distributed during the 2019 International Dentist Congress in Lithuania.

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.

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.
