What is Electrosurgery?

Electrosurgery is the application of a high-frequency electric current to biological tissue as a means to cut, coagulate, desiccate, or fulgurate tissue. (These terms are used in specific ways for this methodology—see below). Its benefits include the ability to make precise cuts with limited blood loss. Electrosurgical devices are frequently used during surgical operations helping to prevent blood loss in hospital operating rooms or in outpatient procedures.

In electrosurgical procedures, the tissue is heated by an electric current. Although electrical devices may be used for the cauterization of tissue in some applications, electrosurgery is usually used to refer to a quite different method than electrocautery. The latter uses heat conduction from a probe heated to a glowing temperature by a direct current (much in the manner of a soldering iron). This may be accomplished by direct current from dry-cells in a penlight-type device. Electrosurgery, by contrast, uses alternating current to directly heat the tissue itself. When this results in destruction of small blood vessels and halting of bleeding, it is technically a process of electrocoagulation, although “electrocautery” is sometimes loosely and nontechnically used to describe it.

Using electrosurgery in oral surgery procedures

Electrocautery is a very useful tool to make a cut or excise soft tissue just like a scaple blade does. While a cut is made; at the same time, electrosurgery coagulate the surrounding blood vessels make surgery bloodless. This will improve visibility during surgery and less blood loss. More over, healing of a wound with electrosurgery is proven to be faster that wound made by scaple blade.

Electrosurgery: Coagulating the gum area before impression taking during tooth preparation for crown fabrication

Dental procedure which can be done with

  • Excision of  lesions (eg. cysts, tumors)
  • Gum surgery
  • Implant placement
  • Crown lengthening
  • Coagulating the gum area before impression taking during tooth preparation for crowns/bridges

Advantages of using electrocautery

  • Less bleeding
  • Can be use to control bleeding
  • Wound heal faster with electrosurgery than using scaple blade
