Abstract
The study aimed to test the effectiveness of cognitive behavioural therapy (CBT) administered by a general dental practitioner (GDP) in a general dental practice. In a two-arm parallel randomised controlled trial, the experimental group received a short dentist-administered CBT-intervention (D-CBT). A best-practice control group (FHM) received dental treatment during sedation with midazolam combined with an evidence-based communication model (The Four Habits Model). Ninety-six patients with self-reported dental anxiety were allocated to the treatment arms at a 1:1 ratio. Modified Dental Anxiety Scale (MDAS) scores spanned from 12 to 25, and 82 patients (85%) had a score of 19 or more, indicating severe dental anxiety. In both treatment arms, scores on MDAS and Index of Dental Anxiety and Fear (IDAF-4C) decreased significantly, but no differences were found between treatment arms. Mean reductions were: MDAS scores: -6.6 (SD=0.5); IDAF-4C scores: -1.0 (SD=1.1). In conclusion, local GDPs in general dental practices with proper competence have the ability for early detection of dental anxiety and, with the use of a manual-based D-CBT or FHM treatment, GDPs could offer efficient first-line treatment suitable for dental anxiety of varying severities.
