⭐ GINGIVECTOMY
📌 POINTS TO PONDER
🔹Gingivectomy is defined as “an excision of the soft tissue wall of the periodontal pocket”.
🔹Failure to produce beveled incision leaves a broad plateau which takes more time than ordinarily required to develop the physiologic contour of gingiva, thus the incision should be beveled at approximately 45° to the tooth surface.
🔹The granulomatous tissue is removed first and then thorough scaling is attempted on the tooth, so that hemorrhage from the granulomatous tissue should not obscure the scaling during surgical procedure.
🔹Gingivectomy may be performed be means of scalpels, lasers,electrode or chemicals.
🔹In gingivectomy, external bevel incision is given at 45° to thetooth surface in apicocoronal direction.
🔹Gingivectomy wound heals by secondary intention.
📌 VIVA VOCE
Q1. How is gingivoplasty different from gingivectomy?
Ans. The purpose of gingivoplasty is different from gingivectomy, as gingivoplasty is just reshaping of gingiva to create physiologic gingival contours,with the sole purpose of recontouring the gingiva in the absence of pockets, while the objective of gingivectomy is to eliminate pocket.
Q2. What are the advantages of light amplification by stimulated emission of radiation (LASER) gingivectomy?
Ans. The advantages of LASER gingivectomy are as follows:
🔸LASER offers an almost completely dry, bloodless surgery.
🔸Because of dry field, surgery time may be reduced.
🔸There is an instant sterilization of the area, decreasing the chances of bacteremia.
🔸This is a noncontact surgery, thus no mechanical trauma to the surgical site.
🔸There is prompt healing with minimal post operative swelling and scarring.
🔸Post operative pain appears to be greatly reduced.
Q3. What is the angulation given for the incision in gingivectomy?
Ans. The incision should be beveled at approximately 45° to the tooth surface.
Q4. What is the major contraindication for gingivectomy procedure?
Ans. The need for bone surgery or examination of the bone shape and morphology.
Q5. What is the objective of gingivectomy procedure?
Ans. Pocket elimination by gingival resection and development of physiologic tissue form for disease prevention.
Q6. Who described gingivoplasty for the first time?
Ans. Goldman in 1950
Q7. Which instruments are used in gingivoplasty procedure?
Ans. Periodontal knife, scalpel, rotary coarse diamond stones or electrodes.
Q8. Which laser is used for gingivectomy procedure?
Ans. Carbon dioxide (CO2) laser having wavelength of 10,600 nm and neodymium-doped: yttrium- aluminium-garnet (Nd: YAG) having wavelength of 1,064 nm both in infrared range.
Q9. How much time it takes for the sulcular epithelium to heal after gingivectomy?
Ans. 3–5 weeks.
