What is a characteristic of air-powder polishing systems?

Air-powder polishing systems are known for their unique method of cleaning teeth by utilizing a mixture of water and fine particles, often sodium bicarbonate or other abrasive agents. This mixture is delivered through a pressurized airflow, facilitating a more efficient and effective cleaning process compared to traditional polishing methods.

The ability to adjust the pressure and the type of abrasive used allows dental professionals to target specific areas while minimizing discomfort for patients. This method is particularly effective in removing extrinsic stains, biofilm, and plaque from both natural teeth and dental restorations, making it a versatile tool in various dental procedures.

In contrast, the other options present limitations that do not align with the capabilities of air-powder polishing systems. For instance, the notion that they can only be used on natural teeth is inaccurate, as they are suitable for a range of dental surfaces, including those with restorations. Additionally, restricting air-powder polishing systems to orthodontic use undermines their broader application in general dentistry. Lastly, claiming that they are ineffective for stain removal contradicts their primary use and functionality, which is to enhance the aesthetic appearance of teeth by effectively removing stains.
