Abrasion is the type of wear produced on the tooth by the friction of exogenous material forced over the surface by incisive, masticatory and grasping functions. It is one of the four common processes that have affected the morphology of newly erupted teeth from the time they first evolved millions of years ago. While some observers have regarded tooth reduction as pathological, there is evidence from comparative and palaeontological studies which demonstrates that these processes are an essential part of the normal, continually changing relationship between the form and function of the dentition. To understand these precise mechanisms is important if one is to replicate nature's 'intentions' in clinical dental procedures.
