She specializes in pediatric and adolescent dentistry and works in a family dental practice near Leipzig.

Sitting behind a bench was one of the most important and relevant aspects of my professional life. After 21 years at the uni I decided to make a PhD. It was the right step. It gave me critical sense in order to develop a line of research. My interest is in digital dentistry.

Dr Debora R. Vilaboa graduated from the Complutense University Faculty of Medicine and Surgery in Madrid. The same year, she was accepted at the Seville School of Dentistry, where she obtained her dental degree. Later on she chose to attend the Advanced Pediactric Dentistry Program at the University of Southern California in Los Angeles.

She lectured on tooth wear as early as 1992, both in Spain and the United States. Understanding how to approach the treatment of young children helped Dr Deborah Vilaboa in her work with tooth wear patients, many of whom had a fear of dentistry. As a pioneer in the field of porcelain laminate veneers, she treated such cases with a novel adhesive concept. Dr Debora Vilaboa soon became a member of the Spanish Society of Stomatological Prosthetics (SEPES) and the Spanish Society of Periodontology (SEPA). Her passion for treating patients and continuing education was rewarded in becoming an active member of the European Academy of Esthetic Dentistry (EAED). She was then able to pursue her restorative and prosthodontic interests, thanks to a truly collaborative and generous exchange of knowledge among the active members that is still a driving force for the team at Vilaboa Clinic. She is also an active member of the Italian Academy of Esthetic Dentistry (IAED). Dr Debora Vilaboa was invited by the San Pablo CEU University to create an undergraduate Esthetic Dentistry Department that she co-directs with her sister, Dr Beatriz Vilaboa. She lectures worldwide in esthetic dentistry, with a focus on tooth wear. She was a contributor to Esthetics in Dentistry (Quintessence, 2016).
