Air abrasion typically operates at what pressure?

Explanation:
Air abrasion works by propelling abrasive particles through a jet of compressed air, so the pressure governs how fast and forcefully those particles strike the tooth surface. About 160 psi provides enough velocity for effective material removal while keeping the spray controllable and safer for the patient; pressures much lower can reduce cutting efficiency, while higher pressures increase aerosol production and the risk of damage or discomfort. In practice, regulators are set near 160 psi to maintain a consistent, effective stream.
