The aim of this study was to evaluate the ability of dental clinicians to rate dental anxiety. A total of 104 clinicians from 24 public dental clinics in the Region of ostergotland, Sweden, examined 1,128 adult patients undergoing their regular dental examination. The patients rated their dental anxiety using the Modified Dental Anxiety Scale and a Visual Analogue Scale. After the examination, the clinicians rated the patients levels of dental anxiety on a Visual Analogue Scale. The correlation (r(s)) between the clinicians and patients ratings of dental anxiety was 0.45. Among highly dentally anxious patients, there was no correlation between clinicians and patients ratings. Dental clinicians rated dental anxiety lower than their patients did, especially if the patients were highly anxious. The ability of clinicians to rate dental anxiety was better when the clinician was older and the patient was older. There was an inverse association between clinicians confidence and their ability to rate a patients dental anxiety. In conclusion, clinicians are unsuccessful in identifying a dentally anxious patient without the concurrent use of patient self-assessment tools. A Visual Analogue Scale is a suitable screening tool in general practice for detection of dental anxiety.
