Knowledge, Practice and Attitude of Dentists towards Cone Beam Computed Tomography

Abstract

BACKGROUND Cone beam computed tomography (CBCT) was first introduced in 2008 and has since seen a tremendous growth in both private dental clinics and dental institutions. This has led to the normalization of CBCT use by general dentists. Therefore, it is essential to assess how and why general and specialist dentists use CBCT. The purpose of this study was to assess the knowledge, practice and attitude towards CBCT among general and specialist dentists working in the kingdom of Saudi Arabia. METHODS In this cross-sectional study, a questionnaire was electronically distributed via email and social media from October 2018 to September 2020. The self-administered questionnaire was divided into five segments: demographics, knowledge, current practice, training and attitude. RESULTS A total of 221 dentists filled the questionnaire including 85 general dentists and 135 post graduate students or specialists. The majority of dentists (81.9 %) demonstrated poor knowledge. Orthodontists and endodontists were most aware of CBCT terms. Most dentists (71.5 %) have a CBCT unit in their practice. Only 34.8 % received CBCT training, the majority of which was theoretical. A positive attitude was noted in 83.2 % of dentists by agreeing to a statement regarding CBCT justification. CONCLUSIONS Poor CBCT knowledge was evident in majority of dentists despite having CBCT in their practice. Dentists are highly aware of the importance of CBCT justification and professional interpretation; however, they lack basic knowledge and training related to this imaging modality. This highlights an institutional gap that policy makers should address in order to ensure the highest quality of patient care. KEY WORDS Cone Beam Computed Tomography; CBCT; Survey
