“…Increased activity of masticatory muscles has been described in cases of bruxism (Eschler, 1961;Ramfjord & Ash, 1971). The increased muscle activity around the oral cavity could be the possible cause of erosion-like striations in dentures and restorative materials, according to Brodie & Sognnaes (1974). Such forces could also be related to erosion of natural teeth and other hard tissues as well as a thinning effect on the gingiva and bone, leaving the root surface of the tooth exposed^-mechanisms recently referred to as 'frictional ablation' (Sognnaes, 1974(Sognnaes, , 1975.…”

This study presents the progress of tooth wear and the change in structural morphology on individual teeth of bruxist subjects, compared with non-bruxers. From the results of this investigation it can be concluded that the tooth wear progressed faster in bruxers than in non-bruxers. Scanning electron microscope investigations revealed in 10 teeth the same pattern of deep grooves and striations on the wear-facets of active bruxers.
