John O. Burgess, DDS, MS - Professor
Dr. Burgess' research interests are applied clinical trials of dental restorative materials, mechanical and physical property testing of dental materials (glass ionomers, composite resins, and ceramics), developing in vitro test methodologies that more closely replicate the oral environment dental materials modification and development of esthetic restorative materials. |

James Broome, DDS, MS - Associate Professor Dr. Broome’s research interests are in the clinical and laboratory evaluation of polymeric restorative materials. His current interest is in stress development during composite resin polymerization, and methods of controlling the stress clinically. In addition, he is collaborating with the Department of Physics in developing a non-destructive method of investigating resin polymerization through the use of Raman spectroscopy. |

Jack E. Lemons, PhD - Professor
The research activities of J. Lemons have focused on the biocompatibility profiles of surgical implant devices with an emphasis on the role(s) of element and/or force transfers along biomaterial-to-tissue interfaces. Current research/student projects include: characterization of cell/fluid interactions with titanium (alpha, alpha-beta and beta) and zirconium alloy (Zirc II) surfaces (PhD study); in vivo and in vitro bone responses to surface modifications of titanium alloy (alpha-beta) implants (MS and PhD studies); biomechanical properties of implant stabilized removable dentures (MS study); in vivo explant and in vitro analyses of polyglass crown and bridge restorations (two MS and one undergraduate DMD study); in vivo and in vitro evaluation of metallic-metallic and metallic-polymeric wear of total joints (MS and PhD studies); and biocompatibility aspects of nanocrystalline carbon and hydroxyapatite modifications of alloys for temporomandibular joint replacement (MS study)

Firoz Rahemtulla, PhD - Professor
The long-term goal of the research of Dr. Firoz Rahemtulla is to elucidate the role of salivary peroxidase system in oral health. In the oral cavity, this system generates an antibacterial agent, the hypothiocyanite anion, and detoxifies hydrogen peroxide. In vivo the salivary peroxidase system may be in a state of dynamic equilibrium which maximizes the production of antibacterial agent and minimizes the accumulation of hydrogen peroxide. Any changes in the dynamic state would result in a loss of the protective function with possible detrimental effects for the oral cavity. In continued effort to contribute to the knowledge of salivary peroxidase system, current work is focused on the regulation of the salivary peorxidase system; basic knowledge of the biological significance of the thiocyanate ion; and the physiological role of hydrogen peroxide in salivary glands and saliva.
