What is the primary use of a celluloid strip in dentistry?

1. To pack gutta percha in canals

2. To form temporary wall for composite filling

3. To smooth and shape canals

4. To remove pulp tissue

The correct answer is: To form temporary wall for composite filling

The primary use of a celluloid strip in dentistry is to form a temporary wall for composite fillings. Celluloid strips are thin, flexible materials that can be used to create a temporary barrier, allowing dentists to shape and contain the composite material within the cavity preparation. This is particularly important because it helps in maintaining the integrity of the filling while it sets, preventing any material from spilling over or becoming distorted by saliva or other oral fluids. The use of a celluloid strip provides a smooth surface that closely mimics the final restoration, which helps in achieving a proper contour and polishing of the filling material. Its adaptability and ease of use make it a preferred choice for many dental professionals when working with composite resins in creating esthetic restorations. In contrast, packing gutta percha, smoothing and shaping canals, or removing pulp tissue are processes that rely on other specific instruments or materials tailored for those particular tasks. Each of these other options corresponds to distinct procedures within endodontics and restorative dentistry that do not involve the use of a celluloid strip.
