One dentist treated all the patients
anxiety
Patients in both treatment conditions were treated by the same dentist, a 40-year-old Norwegian woman, who had completed her dental studies in Oslo 12 years prior to the study. Although she had no relevant specialisation, she had completed a theoretical exam on CBT treatment for dental anxiety (equivalent to a 40-h course) and participated in additional video-assisted training in the practical use of CBT, provided by the co-authors. The RCT study was conducted in a dental practice setting that included two other general dental practitioners, two specialists (surgery and endodontics), and one dental hygienist. The clinic had a shared waiting room.
