This course discusses the clinical and histological significance of frequency and waveform and how to control lateral heat to reduce tissue alteration. It also discusses in detail the advantages, disadvantages, techniques, precautions, and marketing for electrosurgery in practice.

Learning Objectives:

Upon completion of this course, participants should be able to do the following:

  1. Understand the electronics, theory and principles of electrosurgery.
  2. Understand the electrosurgical instrument and its component parts.
  3. List the indications and contraindications for the clinical uses of oral electrosurgery.
  4. List the criteria for selecting an electrosurgery instrument.
  5. Reach a confident performance level.
  6. Understand how to get started using electrosurgery in practice.


Electrosurgery instruments use high frequency radio waves to cut, coagulate, or remove tissue with little or no bleeding. This course will teach the clinical and histological significance of frequency and waveform and how to control lateral heat to reduce tissue alteration. The shave technique, unique to electrosurgery/radiosurgery, is also discussed. This allows the practitioner to contour or remove tissue without using sutures and with minimal discomfort to the patient. The advantages, disadvantages, precautions, and indications for the use of electrosurgery are discussed. Clinicians will see how electrosurgery can become a routine, safe, and predictable procedure in their practices.
