CD-1 Fallacy or Fact - the Necessity of Patency
CE Hours: 1.5
Description: The idea of moving a small instrument through the apical constriction with the intention of preventing debris accumulation and canal blockage during root canal instrumentation, as well as disrupting bacterial biofilms in the foraminal area, has gained increasing popularity among clinicians. Within this presentation the varying histologic and microbiologic conditions of the apical pulp tissue present at the initiation of root canal treatment are illustrated. On the basis of histologic and histobacteriologic observation of a large number of human biopsies, the advantages and disadvantages of this procedure will be critically analysed.
- Explain the different histologic conditions present in the various clinical scenarios.
- List the limitations of current instrumentation techniques in removing vital or necrotic tissue from the apical ramifications and other anatomical irregularities.
- Discuss the impact of apical patency on the wound healing process.

Dr. Domenico Ricucci received his Degree in Medicine in 1982 and his Degree in Dentistry in 1985 from “La Sapienza” University of Rome, Italy. Since then, he has maintained a private practice limited to endodontics, while also directing a personal histopathology research laboratory focused on pulpal and periapical tissue responses to disease and treatment.
His main research interests include tissue reactions to caries, vital pulp therapy, biofilms in endodontic infections, causes of root canal treatment failure, pulp regeneration, and dental trauma.
Dr. Ricucci has authored 122 scientific papers and 24 book chapters, and is the author of the following textbooks/atlases: Patologia e Clinica Endodontica (2009); Endodontology: An Integrated Biological and Clinical View (2013), translated into Russian (2015), Japanese (2017), and Chinese (2019); and the recent Vital Pulp Therapy & Clinical Endodontics: A Biological Approach (2026).
His contributions to endodontic science have been recognized with the Grossman International Award from the French Society of Endodontics (2017) and the Louis I. Grossman Award from the American Association of Endodontists (2023).
