Comparison of tissue response to rotary and ultrasonic dental cutting procedures

摘要: This paper is the third in a series of re­ ports on construction and application to dental use vibration cutting in­ strument operating at ultrasonic frequen­ cies. The first report1 described development o f an experimental instrument. second paper2 reported results six exploratory studies physical characteristics vibra­ tion process. object this report observations limited study concerned with com ­ parative biologic response rotary vibrational cutting. experiment was conducted contribute data toward evaluation cut­ ting Such neces­ sary determine feasibility clinical
