Do You Want to Re-use Diamond Rotary Instruments?

- All surgical instruments that are disposable are single use only!

- Cross contamination risk

- Liability

- Decreased cutting efficiency

- Increased operator fatigue

- Increased heat build-up

- Increased risk of pulp damage

- Increased chair time

- Increased staff injury risk

- Increased staff time for cleaning/sterilize
