In 1998, Brazilian Dentistry lost one of its most eminent professionals, Professor Dr. Hildeberto Francisco Pesce. He was a full professor of Endodontics at the Faculty of Dentistry of the University of São Paulo and the University of São Francisco and a member of the Editorial Board of this Journal. Professor Pesce published numerous scientific articles both nationally and internationally. Besides teaching many specialists of Endodontics, he was very active in post graduate courses, orienting many Master's and Doctorate students who are now professors at other Brazilian Universities. Dr. Pesce dedicated his talents not only to Endodontics but also to Pharmacology and Diagnostics. It will be difficult to fill the void in the national scientific community left by Dr. Pesce.
