What should a dental assistant do to minimize the risk of injury during coronal polishing?

Directing the polishing cup away from the gingival third is crucial for minimizing the risk of injury during coronal polishing. This technique helps to avoid trauma to the gums and soft tissues of the mouth, which can occur if the polishing cup is used too aggressively or improperly positioned. By angling the cup correctly, you can ensure that the polishing action focuses on the enamel surfaces of the teeth rather than coming into contact with sensitive gingival tissues, thus preventing irritation, abrasions, or even lacerations.

Maintaining this technique is not only essential for patient comfort but also promotes a safer and more effective polishing outcome. Adopting safe practices during coronal polishing aligns with standard protocols aimed at protecting both the patient and the dental assistant, fostering a safe clinical environment.
