Behavioural science in dentistry. The role of the dental hygienist in prevention and treatment of the fearful dental patient

摘要

The prevalence of dental anxiety in the general population seems to be fairly stable, and the incidence is not reduced in spite of more modern treatment methods. Intensive fear often leads to avoidance of care and consequences like poor oral health, psychosocial problems and reduced quality of life. The aetiology of dental anxiety is complex, but is often associated with direct traumatic dental experiences during childhood, These negative experiences are reported as painful/unpleasant and are influenced by the patient's perception of lack of coping and control. The theory of latent inhibition indicates that several positive dental appointments before any invasive or painful treatment sessions may act as a barrier to these perceptions of lack of coping This paper is presenting a short overview of behavioural science in dentistry and discussing the role of the dental hygienists as potential key personnel in prevention and treatment of dental anxiety.
