Abstract: Background/Aim: Recording of traumatic dental injuries in the emergency situation with a simple and easily recordable index that will also enable computer registration is advantageous. The aim of this paper is to present a new index to facilitate recording traumatic dental injuries and assess its face and content validity. Materials and methods: The index included information on the type of injury related to the affected structures (enamel, dentin, cement, pulp, periodontal ligament, and alveolar bone) in accordance with Andreasen's classification. In addition, injuries to the alveolar bone and the maturity of the root were included. Fifteen dental trauma experts from 11 different countries rated the codes and content of the "Eden Baysal Dental Trauma Index" using the RAND modified e‐Delphi consensus method. A statement was considered valid after reaching 75% consensus among panel members. Two rounds were necessary for reaching consensus on seven statements and the definition. The last version of the index was then presented online to a feedback group that included 10 experts from five countries to determine the external validity by representative cases. Results: The wording of the definition showed 92.8% agreement in the first round. Statements 1 and 2 gave information about the structure of the index and both reached 90% agreement in the first round. Definition and statements from 1 to 7 reached agreement as 93.3%, 93.3%, 100%, 93.3%, 80%, 93.3%, 80%, and 93.3%, respectively, in the second round. Most of the experts in the feedback group reported that the index was useful and user‐friendly. Conclusion: After a total of two rounds with the panel members and one round with the feedback group, the "Eden Baysal Dental Trauma Index" was approved for face and content validity and external validity was obtained.
