Research & Interests

Dr. Kim's research interests lies in; 1) the role of osteomucosal healing in ONJ development by bisphosphonate and denosumab, 2) the role of epigenetics in aging and HPV-associated oral carcinogenesis, and 3) mechanisms of pulp regeneration in the context of reparative dentin formation. Based on clinical experiences and observations, our laboratory developed animal models that recapitulate multiple disease entities, including ONJ lesions, oral cancer development, and direct pulp capping, to examine the underlying pathophysiology at the preclinical level. Our lab also utilizes in vitro cell culture system and various biochemical techniques to elucidate the fundamental mechanisms at the molecular level.
