Italian version of Corah's Dental Anxiety Scale: normative data in patients undergoing oral surgery and relationship with the ASA physical status classification.

To test the Italian translation of Corah's Dental Anxiety Scale (DAS) and to check the relationship between dental anxiety and the American Society of Anesthesiologists (ASA) physical status classification (ASA-PS), the DAS was translated into Italian and administered to 1072 Italian patients (620 male and 452 female patients, ages 14-85 years) undergoing oral surgery. Patients' conditions were checked and rated according to the ASA-PS. The DAS ranged from 4 to 20 (modus=8, median=10); 59.5% of patients had a DAS of 7-12, 26.1% had a DAS>2, and 10.3% had a DAS>15. The mean DAS was 10.29 (95% confidence limit=0.19); female patients were more anxious than male patients (P< .001), while patients older than 60 years showed a significant decrease in the level of anxiety. Five hundred two patients were rated as ASA-PS class P1, 502 as ASA-PS class P2, and 68 as ASA-PS class P3, with a mean DAS score of 9.69, 10.78, and 11.09, respectively: the DAS difference between groups was significant (P< .001).
