Memory of Pain and Anxiety Associated with Tooth Extraction

Abstract

Concerns regarding pain constitute a large component of dental anxiety, and patients with high dental anxiety are likely to have exaggerated memory and prediction of dental pain. It remains to be investigated, however, if memory of anxiety is exaggerated in a manner similar to that of pain, and if anxiety and pain assimilate in memory over time. A sample of 79 patients presenting for emergency extraction rated their anxiety and pain before, during, and two weeks after the procedure. Measures of trait dental anxiety and fear of pain also were collected. All patients exaggerated their recall of procedure pain, but only those high in trait dental anxiety exaggerated their recall of anxiety. Highly anxious patients reported more pain prior to the procedure and expected more pain; ratings of anxiety and pain for all participants assimilated over time.
