Department of Periodontology

About Our Department

Welcome to the UAB Department of Periodontology. We are committed to optimizing the overall health of our patients and the community through superior periodontal care, education, and outreach. We work to do so through innovative programs in teaching, patient care and research. Well-qualified and passionate faculty direct these efforts supported by dedicated staff.

Research and Scholarly Activity

Periodontology

The Department of Periodontology is actively engaged in clinical and translational research that truly focuses upon the UAB School of Dentistry’s core values: excellence, patient-centered, innovation, and unity of purpose. We aim to conduct research that meets the highest standards in a state-of-the-art facility to provide benefits to our patients and to expand the knowledge base in periodontology. Our research interests include periodontal-systemic connection, innovative regenerative technologies, dental implant innovations, epigenetics, and the periodontal microbiome.

Facilities

Our Graduate Periodontal Clinic is a state-of-the-art facility with five surgical suites and five treatment rooms. We also have a dedicated front desk staff, three skilled dental assistants, and two experienced dental hygienists in a dedicated wellness facility. Digital radiography facilities are in each operatory along with a NOMAD portable radiograph machine for use in nonsurgical and wellness rooms. Both panoramic and CBCT machines are located within the clinical enterprise.

Our Periodontal Research Clinic, located adjacent to the Graduate Periodontal Clinic, has two treatment rooms and one surgical suite as well as a full complement of clinical research materials and storage facilities.

UAB Dentistry is physically connected to both the University Hospital and the Veteran’s Administration Hospital. This allows easy passage to these two facilities where important clinical activities of the advanced education program in Periodontology may be undertaken. Other education, recreational, and research facilities at UAB, a major urban university and medical center, are conveniently located and may be utilized by students in the advanced education programs. The more pertinent of these include the Lister Hill Health Science Library, the Animal Service Facilities, the Bevill Biomedical Sciences, and the Shelby Biomedical Research Buildings.
