Past research as a NIH study principal investigator includes developing and publishing validated Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for the most common TMD - for use in both the clinical and research settings. Past research in TMD management includes assessing the long-term effectiveness, in patients with symptomatic TMJ closed lock with limited mouth opening, of medical management compared to comprehensive rehabilitation with and without TMJ surgery. He has also researched the longitudinal impact of TMJ intra-articular disorders on jaw pain, function and disability. In addition, in the NIH-funded National Dental Practice-Based Research Network, he assessed the management of TMD patients by dentists in their practices. In his last completed project, funded with NIH/NIDCR’s Small Business Technology Transfer (STTR) and Small Business Innovation Research (SBIR) grants, he developed and clinically tested a new version of the Restful Jaw device – a device attached to the dental chair that is designed to support the jaw during dental procedures including the surgical removal of third molars.
