Professor Ji Woon Park's research lab focuses on the intersection of orofacial pain, temporomandibular disorders (TMD), and systemic health factors, particularly sleep disorders and psychological comorbidities. The lab investigates the long-term structural changes in the TMJ using advanced imaging techniques like CT, explores the impact of oral appliance therapy on headache in OSA patients, and examines the role of somatization and psychological distress in TMD. Additionally, the lab contributes to environmental health by modeling particulate control in electrostatic precipitators, reflecting a multidisciplinary approach to health and environmental science.

This study aimed to understand long-term changes of the osteoarthritic temporomandibular joint (TMJ) condyle using computed tomography (CT) and to verify its correlation with clinical characteristics of temporomandibular disorders. Eighty-nine patients (152 joints; 76 female, 13 male) who had taken follow-up CTs (mean follow-up period: 644.58 ± 325.71 days) at least once in addition to their initial evaluation were selected. Cross-sectional demographic and clinical data and longitudinal CT image
Functional jaw limitations were associated with painful TMDs but appear to be unrelated to somatization and psychological distress. Somatization and depression/anxiety were moderately correlated, underscoring the importance of somatic symptom screening when managing TMD patients.
Changes in headache characteristics in obstructive sleep apnea (OSA) patients following oral appliance treatment was investigated for the first time. Thirteen OSA patients with headaches treated with a mandibular advancement device were investigated. Level I polysomnography and Migraine Disability Assessment Questionnaire were completed before and after treatment. Various headache characteristics and concomitant conditions were analyzed. The patient was considered a headache responder when ≥ 30%
Electrostatic precipitators (ESPs) have been widely used to control particulate pollutants, which adversely affect human health. In this study, a computational fluid-dynamic model for turbulent flow, particle trajectory, and particle charging in ESPs is presented using a pre-developed corona discharge model (Kim et al., 2010), wherein electric field and space charge distributions in the plasma region are numerically calculated. The ESP under consideration is a wire-to-plate single-stage ESP, whi
YouTube videos related to TMD contained low quality and scientifically inaccurate information that could negatively influence patients with TMD.
Primary sleep disorders could be an important independent risk factor for the initiation and maintenance of TMD. Patients with sleep disorders should be monitored for possible co-occurrence of TMD-related symptoms that could aggravate sleep disorders in turn.
Short sleep is associated with more comorbidities and unfavourable long-term treatment response in TMD which may be mediated by systemic inflammation. Effective management of sleep is necessary for successful TMD management.
