What is the function of a chisel in dentistry?

To remove decay from teeth
To smooth the enamel margin of cavity preparations on anterior teeth
To pack amalgam into cavity preparations
To carve tooth anatomy on amalgam restorations

The correct answer is: To smooth the enamel margin of cavity preparations on anterior teeth

A chisel in dentistry is specifically designed for shaping and smoothing tooth structures. Its primary function is to smooth the enamel margin of cavity preparations, particularly on anterior teeth. This is essential for achieving a proper fit and finish on dental restorations, as smooth enamel margins help in the adhesion of restorative materials and reduce the likelihood of future decay at the edges of the restoration. While chisels may assist in the broader cavity preparation process, their role in smoothing and refining the margins is crucial for both aesthetic and functional outcomes in dental work. This capability distinguishes chisels from other instruments that are designed for different tasks, such as dentists' hand instruments that remove decay or amalgam carriers that are used to pack materials into cavity preparations.
