Wisdom tooth blind pocket resection, i.e., pericoronary gingivectomy, is performed as follows: anesthesia, disinfection, marking the position of the surgical incision, incision, debridement, gingival trimming, cleaning of the wound and hemostasis.
1. Anesthesia: block anesthesia or local infiltration anesthesia using adrenaline-containing Articaine.
2. Sterilization: preoperative gargling with 0.12% chlorhexidine solution to clean the mouth.
3. Marking the position of the surgical incision: use a periodontal probe to probe the gingival pocket, and then mark the position of the bottom of the pocket to determine the position of the incision.
4. Incision: Cut into the gingiva at the marked position.
5. Cleaning: use the supragingival scaler to scrape off the cut gingival tissue, granulation tissue, foreign matter, etc.
6. Gingival trimming: trimming the edges of the wound with a gingival knife to form a normal physiological shape.
7. Clean the wound and stop bleeding: rinse the wound with saline, and stop bleeding by gauze compression.
It is recommended to go to a specialized hospital for treatment.
