What is an advantage of restoring brown cavitations?

• A. They require high-speed drilling and local anesthesia
• B. They are small enough to allow simplified restorations without high-speed drilling or anesthesia
• C. They require complete crown coverage
• D. They heal on their own without restoration

Answer: (B)

The key idea is that brown cavitations are small, shallow lesions that can be treated with minimally invasive restorations. Because the decay is limited in size and depth, you can clean and seal the area with simplified techniques—often using hand instruments and bonding materials—without the need for high-speed drilling or local anesthesia. This preserves more tooth structure, reduces patient discomfort, and fits with atraumatic, conservative approaches to caries management. The other options aren’t correct because such lesions do not require crown coverage, they don’t heal on their own without restoration, and they aren’t best treated by extensive drilling or anesthesia.
