Abstract
Introduction: CBCT imaging systems are widely used in different dental treatment fields in recent years due to their advantages, such as obtaining 3D images, ease of image acquisition, and reconstruction of data. This study assessed the knowledge and attitudes of dentists in Tehran about the use and indications of the CBCT technique in 2017-2018.
Materials and Methods: In a descriptive cross-sectional study, 199 dentists in Tehran were selected. A questionnaire was designed using standard methods with 24 items. The knowledge scores of the dentists were calculated by assigning 1 score to each correct answer and 0 for each incorrect answer. A linear regression test determined the effects of different parameters on the knowledge scores. SPSS was used for statistical analyses. Spearman’s correlation coefficient was used to analyze the relationship between the knowledge scores and the answers provided for some questions.
Results: The mean knowledge score of the dentists about CBCT prescription indications was 7.77, with a standard deviation of 2.02. The knowledge score range was 3-15. The mean scores of knowledge were similar regarding different parameters. The years in the dental occupation among dentists, age, prescription of CBCT for the patients, or intention to receive education on CBCT software did not affect the prediction of knowledge scores of the dentists (p value < 0.19).
Conclusion: Since dentists in Tehran exhibited moderate knowledge regarding the indications of CBCT, efforts should be made to improve their knowledge level due to their responsibility in oral health and the benefits of CBCT images to increase the quality of dental treatments.
