What type of bur is typically used for rapid removal of enamel and dentine?

The diamond bur is specifically designed for rapid removal of enamel and dentine due to its unique structure, which consists of a steel bur coated with diamond particles. This design allows for quick cutting and efficient reduction of hard dental tissues. The sharpness and hardness of the diamond particles enable the bur to cut through enamel and dentine more rapidly than other types of burs.

In contrast, carbide burs, while effective for cutting, are generally preferred for softer tissue or finer finishing work rather than for quick removal. Stainless steel burs are often used for specific applications, such as preparing tooth surfaces, but do not provide the same efficiency in removing hard tissue. Plastic burs are designed primarily for polishing or abrading softer materials rather than cutting hard dental tissues like enamel and dentine. Therefore, the diamond bur is the optimal choice for rapid removal in dental procedures.
