Development and Validation of Chinese Version of Dental Pain Screening Questionnaire.

Introduction: Dental pain is one of the most prevalent oral complaints. This study aimed to establish a Chinese version of Dental Pain Screening Questionnaire (DePaQ) to help classify patients into three groups of dental pain diseases (group 1, reversible pulpitis and dentine hypersensitivity; group 2, acute periapical periodontitis and irreversible pulpitis; and group 3, pericoronitis).

Methods: The DePaQ was translated from English to Chinese. The clinical subjects (CS, n = 290) and nonclinical subjects (NS, n = 100) with dental pain were collected. The CS were randomly divided into two subsamples: CS1 (n = 203) and CS2 (n = 87). The Fisher discriminant functions of the final 13-item Chinese version of the DePaQ were obtained from the CS1 group, and discriminant validity was further verified in the CS2 and NS groups.

Results: The discriminant functions of the final 13-item DePaQ obtained from the CS1 group were capable of correctly distinguishing 93.1% and 89.0% cases of the CS2 and NS groups, respectively. In the CS2 group, the sensitivity for groups 1, 2, and 3 was 88.0%, 80.0%, and 83.0%, respectively, and the specificity was 95.0%, 95.0%, and 86.0%, respectively. In the NS group, the sensitivity for groups 1, 2, and 3 was 82.0%, 80.0%, and 86.0%, respectively, and the specificity was 91.0%, 97.0%, and 90.0%, respectively.

Conclusions: The Chinese version of DePaQ could help classify the three groups of dental pain diseases and guide medical treatment.
