Professional Interest/Expertise/Specializations:
Dr. Khajotia's research focuses on interactions between oral biofilms and dental biomaterials with an emphasis on developing novel strategies to reduce the initiation and progression of dental caries adjacent to existing restorations (recurrent caries). His work involves studies of the nanoscale topography and surface properties of biomaterials and antibacterial agents on the growth of oral biofilms, particularly Streptococcus mutans. A second area of his research focuses on the mechanical and physical properties of biomaterials in general, and restorative and orthodontic biomaterials in particular. Dental and graduate students are actively involved in his projects, and he is an advocate for the integration of research within the dental and graduate programs' curricula. Research techniques used in his laboratory include atomic force microscopy, confocal laser scanning microscopy, continuous culture bioreactors, 3-dimensional structural analyses of biofilms, development of and testing of biomaterials. His research has been supported by grants from the NCRR and NIDCR (NIH) and several dental manufacturers.
