Gingivectomy is a surgical procedure that removes gingival pockets by eliminating excess gingiva. It has limited indications for conditions like gingival enlargement or shallow pockets. The procedure involves making continuous incisions at the base of pockets and removing tissue. Disadvantages include pain, healing by secondary intention, and risk of exposing bone. Instruments used include specialized knives and marking forceps. The area is dressed post-operatively to aid healing. Drug-induced gingival overgrowth can also be treated with gingivectomy.
