Which statement describes an Inlay?

Which statement describes an Inlay?

• A. It replaces one or more cusps
• B. It does not involve the cusps
• C. It is a fixed bridge
• D. It is used to seal grooves

Answer: (B)

Inlays are indirect restorations placed entirely within the prepared inner walls of a tooth and do not extend over the cusps. Because it stays inside the tooth’s boundaries without covering cusps, the description that it does not involve the cusps is the best fit. If cusps need to be covered, the restoration would be an onlay or crown, not an inlay. A fixed bridge is a different prosthesis spanning gaps between teeth, and sealing grooves refers to sealants, not inlays.
