(PR26) A Survey of Cone Beam Computed Tomography Use for Endodontic Treatment Among General Dentists in the American Dental Association

Abstract: The use of cone beam computed tomography (CBCT) has gained popularity and become more accessible to general dentists in clinical practice. The purpose of this survey was to investigate the acceptance, availability, and usage of CBCT imaging among general dentists who are members of the American Dental Association (ADA). An invitation to participate in a web-based survey was sent to 80,000 members of the ADA. The survey consisted of fifteen questions on CBCT access, type and amount of CBCT training, fields of view (FOV), reasons for use, CBCT reports, and demographics. Of the total number of 1,435 survey responses received, only the 1,366 from general dentists were included in the results. The percentage of general dentists that complete endodontic procedures was 81% with 47% of those having access to an on-site CBCT unit. Oral surgery offices and endodontic specialty offices provide access to a CBCT machine for another 29%. General dentists that have no access to CBCT in their area totaled 33%. Types of CBCT training varied widely with 64% of dentists having 8 hours or less of training. CBCT was used most often for identification of resorption and missed or calcified canals. When a general dentist considers referral, 60% are more likely to refer to an endodontist who regularly uses CBCT imaging. In conclusion, the results of our study indicate the widespread use of CBCT by general dentists, especially for endodontic procedures.
