What is the purpose of sulcular incisions?

• A. Release gums to allow more space
• B. Expose bone for faster healing
• C. Remove calculus
• D. Control bleeding

Answer: (A)

Sulcular incisions are placed along the gingival sulcus so the soft tissue can be released from around the tooth and reflected as a flap without tearing. This creates the necessary space and allows the flap to be elevated with less tension, giving clear access to root surfaces and subgingival areas for debridement or other procedures. They preserve the surrounding tissues and blood supply, which helps healing and aesthetics.

These incisions aren’t primarily for exposing bone, removing calculus, or stopping bleeding. Exposure of bone comes from how the flap is raised and managed, calculus removal is done with instrumentation, and bleeding control is achieved with the overall flap design and hemostatic measures.
