What are the important outcomes in traumatic dental injuries? An international approach to the development of a core outcome set.

Abstract

Background/Aims: There are numerous treatment options following traumatic dental injury (TDI). Systematic reviews of different treatments are challenging owing to the diversity of outcomes reported between clinical studies. This issue could be addressed through the development and implementation of a agreed and standardized collection of outcomes known as a core outcome set (COS). The aim of this study was to develop a COS for TDI in children and adults. The secondary aim was to establish what, how, when and by whom these outcomes should be measured.

Materials and Method: The project was registered with Core Outcomes Measures in Effectiveness Trials (COMET). A web‐based survey was developed to capture the opinions of dentists globally as to which outcomes should be recorded. A list of outcomes was entered into a Delphi Survey and scored by an Expert Working Group (EWG). The scoring was repeated, followed by conference calls to discuss, refine and finalize the COS. The EWG split into small groups of subject‐specific experts to determine how, when and by whom each outcome would be measured.

Results: The questionnaire was completed by 1476 dentists. The EWG identified 13 core outcomes to be recorded for all TDI's. An additional 10 injury‐specific outcomes were identified. A table has been produced for each outcome detailing what, when, and how each outcome should be recorded.

Conclusions: A robust consensus process was used to develop an international COS for TDI in children and adults. This includes both generic and injury‐specific outcomes across all identified domains.
