  • Associate Director, Endodontics Residency Training Programme, Faculty of Dentistry, National University of Singapore

In her role as Head, Endodontic Unit at NDCS, Dr Lui Jeen Nee is actively engaged in endodontic research and publishes actively as a principal investigator, co-investigator and collaborator. She has supervised over 10 endodontic residents for their Masters of Dental Surgery thesis. Her research focuses on endodontic microbiology, endodontic regeneration, vital pulp therapy, cracked teeth, endodontic microsurgery and treatment outcomes. As a practicing endodontist and researcher, her goal is for her research to translate to better clinical outcomes for patients.

Research Focus Areas

Endodontic microbiology, endodontic regeneration, vital pulp therapy, cracked teeth, endodontic microsurgery, treatment outcomes

Current Projects

  • A biomaterials approach for endodontic (dental pulp) regeneration
  • Role of connexin 43 in caries induced pulpitis
  • An analysis of persistent disease following modern endodontic microsurgery
  • Correlation between pulpal inflammatory markers and clinical outcomes of partial pulpotomy
  • Assessment of quality of life of non-surgically retreated and surgically treated endodontic patients: A mixed-method approach
