Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dental and health anxiety are common and potentially distressing problems, for both patients and health care providers. Anxiety has been identified as a barrier to regular dental visits and as an important target for enhancement of oral health-related quality of life. possible groups, (1) high dental anxiety and (2) low dental anxiety. The study aimed to develop and evaluate a computerized cognitive-behavioral therapy dental anxiety intervention (C-CBT) that could be easily implemented in dental healthcare settings.

A cognitive-behavioral protocol based on psychoeducation, exposure to feared dental procedures, and cognitive restructuring was developed. A randomized controlled trial was conducted (N=151) to test its efficacy. Consenting adult dental patients who met inclusion (e.g., high dental anxiety) and exclusion criteria were randomized to one of two groups, (1) immediate treatment (IT) (n=74) or (2) a waitlist control (WL) (n=77).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Analyses of covariance (ANCOVAs) based on intention to treat analyses were used to compare the two groups on dental anxiety, fear, avoidance, and overall severity of dental phobia. Baseline scores on these outcomes were entered into the analyses as covariates.
