Teledentistry, also known as virtual dental examinations, is a potentially innovative approach to increasing access to care. Although research has shown the general benefits of telemedicine/teledentistry in terms of increasing access and improving oral health, there is no research evaluating the use of teledentistry for virtual emergency examinations in a military environment. The objective of this study was to evaluate the diagnostic interrater reliability between virtual and in-person examinations for patients seeking emergency dental care (sick call) at a military dental treatment facility. One hundred subjects received both virtual and in-person examinations on the same day, in a random order. The virtual examiner and subject were stationed in separate rooms and used only a laptop equipped with a camera, microphone, and speaker to complete the virtual exam. In contrast, the in-person examiner had access to all standard care modalities in a dental treatment room. After the first encounter, the subject proceeded to the corresponding virtual or in-person exam, and both examiners determined a diagnosis. Interrater agreement was determined between the two encounters for both diagnosis specialty category and diagnostic code using the Kappa coefficient. The results of the interrater analyses showed a Kappa of 0.644 for diagnosis specialty category (p<0.001) and a Kappa of 0.714 for diagnostic codes (p<0.001). Both analyses indicated substantial agreement. We conclude that teledentistry can be an effective tool for determining a diagnosis and improving access to care for dental emergencies at military dental treatment facilities.
