In vitro assessment of human dentin wear resulting from toothbrushing

It is well-recognized that toothbrushing is the most widely used method for daily oral hygiene maintenance. This in vitro study examines dentin surface wear resulting from the use of an oral hygiene device in a controlled oral condition. Powered toothbrushes produce less wear than manual brushes. However, depending on their design and applied forces, they can also produce varying levels of dentin wear.
