Which device is used to carry and place composite resin into the cavity?

• A. Composite compule
• B. Shade guide
• C. Light cure
• D. Fissure burs

Answer: (A)

Delivering composite resin into a prepared cavity requires a tool that holds a small, pre-measured amount of material and guides it precisely to the target area. The composite compule is designed for this purpose: a pre-measured capsule of resin that fits into a dispensing syringe, allowing the clinician to extrude small increments exactly where needed. This setup enables careful, incremental layering, improving adaptation to cavity walls and reducing waste and potential air entrapment. The other items serve different functions—shade guides match tooth color, a light-curing device polymerizes the resin but doesn’t deliver it, and fissure burs are used to prepare the cavity rather than place the resin.
