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).
  • Association between maxillary sinus characteristics and graft volumetric stability 12 months after lateral window sinus augmentation: A retrospective study.
  • A prospective, randomized clinical trial to compare side incision access mucosal incision (SAMRI) and sulcular tunnel access (STA) root coverage procedures with coronally advanced flap and acellular dermal matrix (ADM) to treat teeth with gingival recession and lack of adequate keratinized tissue.
  • Growth factor availability and release kinetics in Platelet Rich Fibrin versus rh-PDGF with and without bone substitutes: An in vitro analysis.
  • The effect of maxillary sinus anatomical variations, surgical considerations, and patient factors on volumetric changes following lateral wall sinus floor elevation technique for up to 8 years.
  • Gain of Keratinized Mucosa Around Teeth and Dental Implants Using a combination of Strip Gingival Graft and Acellular Dermal Matrix. 
  • Lateral Ridge Augmentation Using allograft bone particles hydrated with or without Recombinant Human Platelet-Derived Growth factor: A clinical and Histological Randomized Controlled Trial.
  • A Randomized, Double-Blind, Active-Control, Single-Center Safety and Efficacy Study of a Novel Dental Gel (LDG) as an Adjunct to Scaling and Root Planing (SRP) in Subjects with Stage II and III Periodontitis.
