Electrosurgery (Coltène Whaledent, U.S.A)

Electrosurgery unit

Three methods of cutting oral soft tissue are used commonlyin dentistry: scalpel, electrosurgery and laser. Each of thesemethods works. However, they are different from the standpointsof hemostasis (arrest of bleeding), healing time and cost of instruments.

Cutting soft tissue with a scalpel is a technique used by everydentist. Disadvantages of cutting soft tissue with a scalpel, includingexcessive blood flow.

Electrosurgery is a controlled, precise application of heatto the soft-tissue site to be cut, achieved by means of carefullydesigned electrodes. The result is a controlled, irreversiblethermal alteration of the soft tissue.

Electrosurgery are used for:

  • exposing impacted tooth
  • operculectomy (removal of soft tissue covering impacted tooth)
  • gingivectomy (removal of gingival tissue)
  • gingivoplasty (recontouring gingival tissue)
  • tissuemanagement for fixed prosthodontics
  • increasing accessfor restorations and crown build-up
  • crown lengthening
  • periodontal pocket reduction
  • frenectomy


These are the advantages of electrosurgery:

  • cuts are made with ease when the device is set correctly
  • hemostasis is immediate (minimal bleeding)
  • cutting is consistent
  • the wound is nearly painless after the procedure
  • the soft tissue has minimal trauma;
