How does using cotton wool in sulci benefit dental treatment?

Using cotton wool in sulci is beneficial because it effectively retracts soft tissue away from the teeth. This retraction is crucial during various dental procedures as it provides the dentist with improved visibility and access to the treatment area, allowing for more precise and effective work. By keeping the soft tissues like gums away from the teeth, the risk of injuries or complications during treatment is also minimized.

This technique is particularly important in procedures such as fillings or crowns, where maintaining a dry and clear working field is essential. Other options, while relevant to dental practice, do not directly describe the role of cotton wool in sulci. Filling cavities is not the function of cotton wool; it serves more as a protective and retraction tool. Enhancing aesthetic quality does not apply in this context either since cotton wool is not used for aesthetic purposes. Additionally, while preventing pain during procedures is a vital part of dental treatment, cotton wool does not inherently provide pain relief; this function is typically achieved through analgesics or topical anesthetics.
