What is a common use for cotton rolls in dentistry?

Cotton rolls are primarily utilized in dentistry to absorb moisture and isolate specific areas of the oral cavity during various procedures. This function is critical because maintaining a dry working area is essential for the effectiveness of dental materials, such as adhesives and sealants, that require a moisture-free environment to bond properly. Additionally, cotton rolls help manage saliva and blood, which can interfere with the visibility and accessibility of the treatment area.

Using cotton rolls improves the comfort of both the patient and the practitioner by providing an effective means to control moisture without needing more complex isolation techniques, like rubber dams. They are versatile and easy to place, making them a staple in a dental practice for procedures such as fillings, crown placements, and other restorative treatments.
