Abstract

Abstract A mechanical computerized three-dimensional scanner with a resolution of 1 μm was used to assess loss of enamel caused by orthodontic bonding and debonding. A total of 2646 measurements was performed on six human premolars. The results showed an average loss of enamel of 7.4 μm. The range was between 1 and 52 μm, which may account for discrepancies with earlier studies that measured only a few points per tooth surface. (Am J Orthod Dentofac Orthop 1997;112:666-9.)
