In September 2001, dentistry's most respected independent research institute completed a comprehensive study of the cut speed, longevity, clogging, concentricity, retention in handpieces, effect the coolant water and problems of reuse with single-use vs. multi-use diamonds.

The study concludes:

• All diamonds degraded during use & reuse accentuated degradation.

• Combined lab & clinical data showed highest rated & best performing single-use diamond was NeoDiamond.

• Due to damage during use, difficulty cleaning & increasingly slower cut, patients receive optimal service when a new diamond is used for each prep.

• Clinicians will save money and provide better care if they use single-use diamonds to cut a single prep.
