Turesky and Glickman125 made a histochemical evaluation of gingival healing in experimental animals on adequate and vitamin C-deficient diets. In this study, 44 guinea pigs weighing 224 to 362 g were assigned to three protocols: Group I, complete diet and gingivectomy; Group II, vitamin C-deficient diet; Group III, vitamin C-deficient diet and gingivectomy. Animals in Groups II and III showed clinical evidence of scurvy by day 14. Gingival biopsies were obtained from Group II after 18 and 24 days on the scorbutogenic diet. Gingivectomies were performed on the Group III animals after 14 study days. Specimens of healing gingiva were removed between 4 and 21 days after gingivectomy. The same procedure and schedule were followed for the Group I control animals. The diet of Group III was supplemented with 10 mg ascorbic acid per day for 10 days following the postoperative experimental period. Gingival tissues were either fixed in chilled absolute alcohol for 48 hr at 5°C or in alcoholic formalin for 24 hr. Serial sections were stained for ground substance, basement membrane, and glycogen.
Radiosurgical Techniques
Published in Jeffrey A Sherman, Oral Radiosurgery, 2020
A gingivectomy is a surgical procedure performed to eliminate gingival pockets and unsupported gingival tissue in inflammatory periodontal disease. The gingivectomy is only performed in areas of supra-bony pocketing with adequate areas of attached gingiva remaining after tissue removal.

Figure 3 (see color insert)* shows an uncomplicated crown fracture after an accident. The fracture edges were bevelled and smoothed off to create a stepless transition from the composite resin to the enamel. If only the enamel is bevelled, there will be a visible border between enamel and resin because of the difference in refraction coefficient. A local gingivectomy was performed before the treatment.

Although clinically MH is not a medical problem or a disease, the demand for cosmetic corrections is on the increase, mainly by fair-skinned people and when MH is located on the anterior labial gingiva (2–5).This problem is aggravated in patients with a “gummy smile” or excessive gingival display while smiling (2–7). Gingival depigmentation is a periodontal surgical procedure, whereby the gingival hyperpigmentation is removed or reduced with different treatment methods, such as bur abrasion, scraping with scalpel, partial thickness flap, gingivectomy, cryotherapy, electrosurgery, free gingival autografting, chemical methods, subepithelial connective tissue graft, lasers and combination techniques (1–4). Even though selection of a technique is mainly based on clinical experience and individual preferences, most authors recognize laser ablation as the most effective, pleasant and reliable technique for depigmentation of gingiva (1–4).

The age of patients ranged from 17 to 30 years, they all needed a soft tissue gingivectomy procedure in two quadrants of the maxillary anterior teeth. Patients received scalpel gingivectomies in the right quadrant of the arch needing treatment followed by Coepack application (group A), while on the left quadrant they received the same procedure but the wound was covered by the selected ketorolac/lidocaine wafer (group B).

The gingivectomy and gingivoplasty were performed following the same protocol and technique described previously. Thus, the cuts were precise, there was no bleeding and the patience experienced good transoperatory visualization during the procedure. Furthermore, the patient did not report any local discomfort, and no analgesic medication was required postoperatively. The gingival tissue was sent for histopathological analysis.
