Laser operculectomy is a minimally invasive periodontal surgical procedure in which a dental laser is used to remove the operculum (a flap of gingival tissue covering a partially erupted tooth), most commonly associated with partially erupted mandibular third molars. Indications • Recurrent pericoronitis • Pain and inflammation around partially erupted teeth • Difficulty in maintaining oral hygiene under the operculum • Prior to orthodontic or prosthodontic treatment Advantages of Laser Operculectomy • Bloodless surgical field • Minimal post-operative pain and edema • No sutures required • Reduced bacterial contamination • Faster healing • High patient comfort and acceptance Healing • Initial healing: 5–7 days • Complete healing: 2–3 weeks

Apicoectomy is a surgical endodontic procedure in which the apical portion of a tooth root is resected, followed by removal of periapical pathology and retrograde sealing of the root canal, when conventional root canal treatment has failed or is not feasible. Indications • Persistent periapical infection after root canal therapy • Obstructed canals (calcification, broken instrument, post) • Apical cyst or granuloma not resolving with RCT • Overfilled root canal with persistent symptoms • Root perforation near apex Advantages • Eliminates persistent apical infection • Preserves natural tooth • High success when properly indicated • Immediate removal of periapical pathology Success Rate • Approximately 80–90% with modern microsurgical techniques

Laser gingival depigmentation is a minimally invasive periodontal esthetic procedure used to remove melanin pigmentation from the gingival epithelium using dental lasers, resulting in a lighter, more uniform gingival appearance. Indications • Physiologic (racial) gingival pigmentation • High esthetic demand (gummy smile, anterior region) • Patient dissatisfaction with dark gums Advantages • Bloodless field (excellent hemostasis) • Minimal postoperative pain and swelling • No sutures or periodontal dressing required • Faster healing • High patient comfort • Reduced risk of infection Healing • Initial healing: 7–10 days • Complete epithelialization: 2–4 weeks
