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.

Active Studies

  • A dental implant registry of treatment outcomes of implant therapy by practitioners in the National Dental Practice Based Research Network (UG3 DE030090)
  • A multicenter, phase III, prospective, randomized, active comparator study with a parallel group, paired patient study design comparing standard root planing versus a Periodontal Structure Repair device (PSR) to assist with the treatment of pockets caused by periodontal disease
  • 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
  • Association Between Buccal Wall Thickness of Maxillary Sinus and Schneiderian Membrane Perforation During Lateral Window Sinus Augmentation: A retrospective study
  • Ideal Gingival Display Upon Full Smile: A comparative evaluation in American dental professionals and laypeople.
  • A prospective, randomized clinical trial to compare vestibular incision supraperiosteal tunnel access (VISTA) and sulcular tunnel access root coverage procedures with coronally advanced flap and acellular dermal matrix (ADM) to treat teeth with gingival recession and lack of adequate keratinized tissue
  • Comparing inflammatory markers in patients with and without depression with chronic periodontitis
  • Identification and application of gingival mesenchymal stem cells for dental tissue regeneration
