Dr. Arnaldo Castellucci

Dr. Arnaldo Castellucci is an internationally recognized endodontist and educator based in Florence, Italy. He trained in endodontics at Boston University under Prof. Herbert Schilder and maintains a practice limited to endodontics. Dr. Castellucci is a Past President of both the Italian Endodontic Society and the International Federation of Endodontic Associations, a Visiting Professor at the University of Florence, and an active member of major international endodontic organizations. He is the author of the textbook Endodontics and a global lecturer known for his precision-driven and biologically sound approach to endodontic treatment.

Dr. Paula Villa

Dr. Paula Villa is an endodontist based in Medellín, Colombia, with a clinical practice limited to endodontics and endodontic microsurgery. She graduated from Universidad CES and is the co-founder of the graduate endodontic program at Universidad de Antioquia, where she serves as a Titular Professor and is actively involved in advanced clinical and academic training.

Dr. Villa is a former President of the Colombian Association of Endodontists and a recognized contributor to the scientific literature, with publications in peer-reviewed journals. An international lecturer, she is known for her biologically driven, evidence-based approach to endodontic microsurgery, with a particular focus on regeneration, apical repair, and precision decision-making.
