Which technique is most commonly used for stain removal in dentistry?

Rubber cup polishing is the most commonly used technique for stain removal in dentistry because it effectively incorporates a polishing paste, which typically contains abrasives and fluoride, into the procedure. The rubber cup, when attached to a dental handpiece, allows for controlled application on tooth surfaces, making it particularly efficient for removing stains, plaque, and other debris without damaging the enamel.

This method is often favored in clinical practice for its ease of use and ability to reach various surfaces in the mouth, including interproximal areas. By using a rubber cup with appropriate polishing paste, dental professionals can achieve a smooth and shiny surface, which not only enhances aesthetics but also contributes to patient comfort.

While other techniques, such as hand scaling and ultrasonic scaling, target calculus and plaque removal, they are not specifically designed for stain removal. Air polishing can also be effective but is typically used in more specialized circumstances and may not be as widely used in routine cleanings compared to rubber cup polishing. Therefore, rubber cup polishing stands out as the primary method for stain removal due to its effectiveness and practicality in everyday dental hygiene practices.
