The Congress venue will be the beautiful Bologna (Palazzo della Cultura e dei Congressi, Piazza della Costituzione 4/A - 40128 Bologna), which will be the scenery of two absolutely captivating days that boast the remarkable scientific contribution of valued Italian Speakers. Two days of deepening and updating of the most important topics of contemporary Endodontics with the most distinguished Italian Endodontists: SIE’s Active members.
