Through laboratory and clinical research our faculty and postdoctoral students are expanding knowledge and exploring new treatments. Current projects include:

  • The use of contemporary molecular microbiological approaches to characterize endodontic microflora and its association with outcomes of regenerative endodontic therapy.
  • Molecular and clinical characterization of symptomatic and asymptomatic irreversible pulpitis.
  • Identifying the association of chronic systemic diseases and the use of long-term systemic medications with the prevalence, pathogenesis and healing of apical periodontitis.
  • The effectiveness of antibiotics and the prevalence of antibiotic resistance genes in spreading endodontic infections.
  • The disruption of Endodontists’ practice by the COVID-19 pandemic.
  • Aerosol generation patterns and reduction during endodontic access preparations.
  • Evaluation of dynamic guidance in endodontic microsurgery.
  • The effectiveness of topical antimicrobial agents for endodontic infections.
  • The role of chewing forces in the dissemination of endodontic microflora.
