A celluloid strip is utilized to create a temporary wall for composite filling in dental procedures. This thin, flexible strip provides a moldable barrier that helps shape the composite material during the restoration process, ensuring that the filling conforms to the desired anatomy of the tooth and maintains proper contour while setting. The transparency of the celluloid strip also allows the dentist to accurately position the material and layer it as necessary, ensuring optimal aesthetics and functionality of the completed restoration.

The other options serve different purposes in dentistry. A pulp tester is used to assess the vitality of the dental pulp, an endo plugger is designed for condensing filling material in root canals during endodontic treatment, and a bone file is employed to smooth and shape bone during surgical procedures. These tools do not have the capability to create a temporary wall for composite fillings.
