Correct answer: E — Full-thickness envelope flap incision

The No. 15 scalpel blade is the most commonly used blade in oral surgery and periodontal surgery. Its small, curved cutting edge is ideal for intraoral incisions including mucoperiosteal flap design (sulcular, releasing), excisional/incisional biopsies, frenectomies, and gingivoplasty. The No. 12 blade (curved, pointed) is used for incision and drainage in palatal and interproximal areas. The No. 15C is a narrower version of the No. 15 for precision work.
