  Background Educating dentists in treatment methods for dental anxiety would increase the patients’ access to treatments that are important to their oral health. However, to avoid adverse effects on comorbid symptoms, involvement by a psychologist has been considered necessary. The objective of the present paper was to evaluate whether a dentist could implement systematized treatments for dental anxiety without an increase in comorbid symptoms of anxiety, depression or PTSD. Methods A two-arm parallel randomised controlled trial was set in a general dental practice. Eighty-two patients with self-reported dental anxiety either completed treatment with dentist-administered cognitive behavioural therapy (D-CBT, n = 36), or received dental treatment while sedated with midazolam combined with the systemized communication technique “The Four Habits Model” (Four Habits/midazolam, n = 41). Dental anxiety and comorbid symptoms were measured pre-treatment (n = 96), post-treatment (n = 77) and one-year after treatment (n = 52). Results An Intention-To-Treat analysis indicated reduced dental anxiety scores by the Modified Dental Anxiety Scale (median MDAS: 5.0 (-1,16)). The median scores on the Hospital Index of Anxiety and Depression (HADS-A/D) and the PTSD checklist for DSM-IV (PCL) were reduced as follows: HADS-A: 1 (-11, 11)/HADS-D: 0 (-7, 10)/PCL: 1 (-17,37). No between-group differences were found. Conclusions The study findings support that a general dental practitioner may treat dental anxiety with Four Habits/Midazolam or D-CBT without causing adverse effects on symptoms of anxiety, depression or PTSD. Establishing a best practice for treatment of patients with dental anxiety in general dental practice should be a shared ambition for clinicians, researchers, and educators. Trial registration The trial was approved by REC (Norwegian regional committee for medical and health research ethics) with ID number 2017/97 in March 2017, and it is registered in clinicaltrials.gov 26/09/2017 with identifier: NCT03293342.

  In an earlier randomized controlled trial of dental anxiety treatments (n = 96) we compared the effects of dentist-administered cognitive behavioural therapy (D-CBT) and dental treatment supplemented with the Four Habits communication model plus midazolam sedation. Both treatments, applied in a general dental practice, were associated with a clinically relevant decrease in dental anxiety. In this follow-up study, 52 of the 82 treatment completers responded to an online questionnaire 1 year post-treatment. Reduction in dental anxiety persisted for both treatment groups. From baseline to 1 year post-treatment the Modified Dental Anxiety Scale was reduced by 7.8 [SD: 4.4; Cohen's d effect size: 1.2 (CI: 0.8–1.7)] and 7.8 [SD: 4.2; Cohen's d: 1.4 (0.9–1.8)] in the D-CBT and Four Habits/midazolam groups, respectively. Most patients (74% for D-CBT, 80% for Four Habits/midazolam) continued with dental treatment. Nine patients in the D-CBT and seven in the Four Habits/midazolam groups received additional CBT treatment from a psychologist/dentist team. Both methods tested should be accessible to interested dentists who receive adequate training. Effective first-line treatments for dental anxiety in general dental practice can generate more accessible care pathways for patients with dental anxiety. Evidence-based dental anxiety treatment programmes should be included in the dental curriculum and established as best practice for dentists.

  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.
