Periapical Lesion
Effect of Piezoelectric Device on Intraoperative Hemorrhage Control and Quality of Life
Most osteotomies and apicoectomies in periapical surgeries are performed by surgical carbide or diamond burs. But greater pressure is applied during cutting which causes more thermal and mechanical damage to the bone.
