The Jacox Lab aims to improve patient care and outcomes in oral health. This goal takes shape via several tracks of interdisciplinary human studies:
-A primary focus of the lab has been on outcomes of jaw surgery patients, who suffer from Dentofacial Disharmonies (DFD). Patients with DFD have severe skeletal disproportions with underbites or open bites, necessitating orthodontics and jaw surgery for full correction. Roughly 80% of our patients with DFD exhibit speech distortions, compared to 5% of the general population, which negatively impact their self-confidence and quality of life. Despite patients pursuing invasive surgery, it is unknown whether jaw surgery is palliative for articulation errors. We are using ultrasound, audio and video imaging to explore the mechanism of articulation errors among patients with DFD. Furthermore, our lab is conducting a longitudinal study of DFD patients to determine if jaw surgery improves speech distortions, in collaboration with oral surgeons, linguistics and speech pathology.
-An additional focus of our lab has been studying use of Animal Assisted Therapy for management of anxiety and pain in dentistry. Dental anxiety effects 21-50% of patients and is associated with poor long-term oral health outcomes and need for urgent care due to dental avoidance. Non-pharmacological behavior interventions like dog therapy holds promise for reducing pain and anxiety perception for patients, and therefore improving dental experiences and promoting improved health outcomes. The lab is conducting a randomized controlled trial to evaluate best practices for canine therapy in pediatric dentistry, in collaboration with pediatric dentists, a psychology professor whose expertise is anxiety, and the UNC Biobehavioral Lab.
-As part of the COVID-19 research response, we are studying FDA-approved antiseptic mouth rinses for their ability to limit salivary viral infectivity to reduce risk of SARS-CoV-2 transmission. If an oral rinse is found to be efficacious at inactivating the SARS-CoV-2 virus, it could be a valuable preventative measure in settings where masks are removed, such as dental care, social settings, eating out, or work presentations. This study is conducted in collaboration with leading virologists and infectious disease experts at UNC.
