Gingivectomy is the surgical excision of gingiva to remove diseased pocket walls and expose tooth surfaces. It is indicated for conditions like suprabonny pockets, fibrous enlargement, and crown lengthening. There are several types of gingivectomy including surgical, chemosurgery, electrosurgery, cryosurgery, and laser gingivectomy. The surgical procedure involves marking pockets, making internal beveled incisions, removing diseased tissue and calculus, and placing a periodontal pack. Post-operative healing occurs through clot formation, granulation tissue growth, and epithelialization over 2-3 weeks.
