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

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

Answer: (A)

Sulcular incisions in dogs require a precise, controlled cut that follows the gingival sulcus without tearing delicate tissue. A small, finely tapered blade gives you the control to stay within the sulcus and produce a clean incision along the tooth. The blade chosen for this job is the fifteen blade, valued for its compact tip and balance of stiffness and finesse—enabling a smooth incision in the tight confines of the canine dentition while minimizing trauma and bleeding. Other blades have larger cutting edges or different tip geometries that are harder to maneuver in the sulcus and can cause more tissue disruption, which is why the fifteen blade is preferred for sulcular incisions.
