    Teaching Areas

    Course Director for Periodontics 610-1 the first course on periodontics. Topics include anatomy, pathophysiology, disease classification, and epidemiology. The 610-1 course emphasizes use of evidence based approaches to understanding how clinicians can evaluate new therapeutics. Students work in small teams presenting one hour lectures on current periodontal disease clinical reasearch topics. Lecturer in Periodontics 610-2 on topic of ultrasonic instrumentation. Clinical instruction in Periodontics specialty clinic and in preclinical laboratories.

    Research Areas

    Principal Investigator, Obstetrics Periodontal Therapy Study for UMC study site for this NIDCR funded multicenter clinical trial. Objective of the study is to test whether initial periodontal therapy reduces preterm birth. OPT study is being conducted in clinics at the Jackson Medical Mall, the School of Dentistry and Weizer Hospital Obstetrics Diagnostic Unit. The OPT Study concluded in 2006. Findings from the OPT Study were that nonsurgical periodontal care did not influence incidence of preterm birth. A second finding was the safety of dental care provided during the second trimester of pregnancy. Funding has been granted for a study of the effects of OPT Study treatments on neurodevelopment of infants born to OPT Study mothers. The OPT Neurodevelopment Study will conclude in early 2009.

    Clinical Interests

    Conduct of clinical trials in periodontal disease treatment. Use of new technologies to improve outcomes of long term periodontal care. Current interests include use of disinfection during periodontal maintenance therapy and prevention of intergeneration oral disease transmission in at risk populations.

The OPT Study completed 2006. Published OPT Study findings include lack of effect on nonsurgical periodontal therapy on preterm birth. A second finding is that dental care during the second trimester of pregnancy is safe. Funding has been granted for a study of the effects of OPT Study therapy on neurodevelopment of infants born to mothers in the OPT Study. This study will be conducted working with the Child Development Clinic in Batson Children's Hospital. The OPT Neurodevelopment Study will conclude in early 2009.
