Aim:
Anxiety is a relevant problem in dental practice. The Modified Dental Anxiety Scale (MDAS) is a brief, simple questionnaire consisting of five questions with a total score ranging from 5 to 25, the Italian version of which is not available yet. The aim of the study was to provide an Italian version of the MDAS and check its reliability in oral surgery, which is a major cause of dental anxiety due to the expected perception of pain and suffering.
Methods:
The Italian version of the test was administered to 230 patients (98 male and 132 female patients, ages 14-88 years) undergoing oral surgery. Further recorded data were: American Society of Anaesthesiologists physical status classification (ASA-PS), frequency of visiting the dentist and any previous distressing experiences in dental or medical setting.
Results:
The internal consistency of the test was high, with a Cronbach's alpha=0.92. The MDAS score was significantly higher in females (p<0.0001) and in patients with previous distressing experiences in medical and/or dental settings (p<0.0001); the correlation with age (p=0.01) and frequency on visiting the dentist (p=0.02) were also significant.
Conclusions:
The patients' selection (oral surgery only) may be a limit of the study, which might not provide an estimation of anxiety prevalence in the general dental population; however our result agree with those of studies performed in other Countries in the generic population, suggesting the absence of major differences with respect to the surgical setting and show the reliability and manageability of the Italian version of MDAS.
