Grand challenges in dental informatics.

When truly significant scientific challenges are overcome, it profoundly changes the daily activities, as well as the future research activities, of everyone involved in the related field. By identifying and describing the grand challenges facing a scientific field, we can help funding agencies identify and prioritize projects for support, stimulate and encourage new investigators to work on these intellectual and technological challenges, and help define the field itself. In this article, we present an informatics-oriented, future-patient-care scenario, then describe a series of applications and the related informatics grand challenges facing the dental field today. New techniques and technologies to help us overcome these challenges would facilitate the development of truly monumental applications, such as a comprehensive electronic oral health record, an automated dental treatment planning system for all diagnoses, or a system to profile patient risk for chronic oral diseases.
