Final answer:
Cotton rolls or dry angles must be moistened before removal to prevent damage and pain to the oral mucosa. Neglecting this can result in discomfort and mucosal tears which may require further treatment.
Step-by-step explanation:
When cotton rolls or dry angles are used in dental procedures, they should be moistened with water before removal. If they are not moistened, the dry cotton can adhere to the mucosa, causing discomfort and potentially damaging the delicate tissues upon removal. This can result in pain for the patient and may lead to minor injuries, such as mucosal tears, which could subsequently require additional treatment to heal. It is crucial that dental professionals take care to moisten cotton products to ensure patient safety and comfort. Similar to how a liquid fabric softener can be added to the final rinse cycle of laundry such as cotton items to prevent a harsh feel, moistening the cotton rolls in dentistry plays a preventive role in maintaining softness and preventing damage to the oral tissues.
