Which instrument is typically used to cut and prepare the tooth?

The straight fissure bur is specifically designed to cut and prepare tooth structure. This instrument has a straight, cylindrical shape with sharp edges that are ideal for creating smooth, precise cavities or shaping tooth enamel. It allows dental professionals to efficiently remove decay and prepare the tooth for restoration procedures, such as fillings or crowns. The design of the straight fissure bur enables the operator to have better visibility and control, which is essential for achieving the desired tooth preparation.

Other instruments, while important in dental procedures, serve different functions. For example, a cavit is used in temporary tooth restoration but does not cut; the Glick is primarily utilized for condensing material and carrying it to the tooth but does not prepare or cut the tooth itself; and the endo explorer is used to navigate and explore the root canal system but is not intended for cutting or shaping tooth enamel or dentin. This specialized function of the straight fissure bur makes it the appropriate choice for cutting and preparing teeth during dental procedures.
