Air abrasion yields which sensory effect during preparation?

• A. It provides enhanced tactile feedback
• B. It is painless
• C. It lacks tactile sensation
• D. It restores sensation to normal quickly

Answer: (C)

During air abrasion, material is removed with a jet of air and abrasive particles rather than with a rotating cutting drill that directly contacts the tooth. Because there isn’t the same direct mechanical engagement and vibration you get with conventional drilling, the patient’s sensory input from the cutting process is greatly reduced. The procedure may feel like a spray or breeze of air and powder, but the typical tactile sensation of drilling is minimized. That’s why this method is described as lacking tactile sensation during preparation.

Notes on the other ideas: claiming it’s universally painless isn’t always accurate—some patients may feel cold spray or mild discomfort—and restoring normal sensation isn’t the aim or outcome of air abrasion.
