This study investigated the use of cone-beam computed tomography (CBCT) by endodontists in Germany and Switzerland. Sixty-eight German endodontic specialists (G-ES), 22 Swiss endodontic specialists (CH-ES) and 95 dentists with a German Master of Science in endodontics (MSc) were invited to participate. Data on the timing of diagnostic assessments, endodontic case difficulty and indications for CBCT use were collected by questionnaire. The frequencies of pre-, intra- and postoperative use of periapical radiography and CBCT were analysed by case difficulty level. In high difficulty cases, access to a CBCT device was significantly associated with the frequency of both pre- and intraoperative CBCT use. The type of endodontic qualification had a significant impact on the rate of preoperative CBCT use in high difficulty cases. German endodontic specialists used preoperative CBCT more frequently than CH-ES and MSc. Our findings show that CBCT is a valuable imaging tool for endodontists, particularly in high difficulty cases.
