What is required before performing mechanical polishing on clinical crowns?

Mechanical polishing on clinical crowns is a procedure intended to enhance the surface smoothness and overall appearance of the teeth. Before this process occurs, it is crucial to remove any calculus deposits through proper instrumentation. Calculus is hardened plaque that can lead to periodontal issues and can interfere with the polishing process by trapping polishing pastes and preventing an effective finish.

By ensuring that the crown is free from calculus, the polishing procedure can effectively enhance the surface without risking damage or creating uneven surfaces. This step not only improves aesthetics but also contributes to the overall health of the surrounding gum tissue by minimizing the risk of plaque accumulation.

Other options, such as fluoride application, taking radiographs, or referring to a dentist, are not prerequisites for mechanical polishing. While they may be important aspects of dental treatment or care, they do not directly relate to or prepare the clinical crown for the polishing procedure itself. This focus on removing calculus before polishing aligns with best practices in dental hygiene, ensuring optimal outcomes for the patient's oral health.
