In sulcular incisions for cats, which blade size is used?

• A. 11 blade
• B. 15 blade
• C. 10 blade
• D. 12 blade

Answer: (A)

Sulcular incisions in cats require a blade that can fit neatly into the narrow gingival sulcus and make a precise, shallow cut along the sulcular epithelium. A small, slender blade with a sharp, pointed tip is ideal because it allows controlled, stab‑like entry right along the tooth–gum junction without tearing surrounding tissue. This precision minimizes trauma and helps preserve the gingiva while providing a clean path for reflecting the mucoperiosteal flap. Larger blades are harder to maneuver in the tiny feline sulcus and increase the risk of an overly wide incision, more bleeding, or inadvertent tissue damage. So the best choice is the small, narrow blade designed for precise crevicular incisions.
