Researchers at the Center for Neurosensory Disorders, a part of the University of North Carolina at Chapel Hill School of Dentistry, served as the lead researchers in the first large-scale clinical jaw-pain study, called the Orofacial Pain: Prospective Evaluation and Risk Assessment (OPPERA). The study, led by Dr. William Maixner, Director of the CND at UNC, provides new insights into potential causes of tempromandibular joint disorders.
