Which option listed for correcting loss of attachment involves surgically opening a space to access the root?

• A. Opening root planing
• B. Grafts
• C. Surgical flap
• D. Perioceutics

Answer: (C)

Creating access to the root by surgically reflecting the gingival tissue is the essence here. A surgical flap involves lifting a mucoperiosteal flap to expose the root surfaces and adjacent bone, giving the clinician a direct view and room to thoroughly debride, scale, and plan the root, and to address bony defects if present. This deliberate opening of space around the root is what enables effective correction of attachment loss, since you can mechanically remove calculus and diseased tissue that have contributed to the attachment decline and, if needed, plan regenerative steps.

The other options don’t provide that direct access to the root. Grafts aim to add tissue or bone rather than create root access for debridement. Perioceutics refers to drug delivery rather than a surgical exposure. Opening root planing isn’t a standard mechanism for gaining surgical access; root planing itself is a debridement step that typically follows or accompanies flap access, not the act of surgically opening a space.
