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, endosseous dental implant innovations, epigenetics, and the periodontal microbiome.

Active studies include:

  • Prospective Study of Bone Augmentation Techniques in Extraction Sockets (NCT01836783)

  • Safety, Efficacy and Treatment Regimen Study of ST266 in Subjects with Chronic Periodontitis (NCT02761993)

  • Survey of Oral Hygiene and Health of Mother and Child at 1-4 Year Recall Period (NCT02922010)

  • A Randomized Trial to Evaluate the Effect of Allograft Bone Particle Size on Histomorphometric and Clinical Outcomes following Ridge Preservation/Augmentation
