Copper deficit as a potential pathogenic factor of reduced bone mineral density and severe tooth wear [PDF]
, 2013 SUMMARY: The study evaluated if men and women with severe tooth wear were at increased risk of general bone loss. Enamel biopsies obtained from 50 subjects aged 47.5 ± 5 years showed decreased copper content, which was associated with reduced spine bone ...

Helical gear wear monitoring: Modelling and experimental validation [PDF]
, 2017 Gear tooth surface wear is a common failure mode. It occurs over relatively long periods of service nonetheless, it degrades operating efficiency and leads to other major failures such as excessive tooth removal and catastrophic breakage.

New Perspectives on Tooth Wear [PDF]
International Journal of Dentistry, 2012 Some of the efforts that have been made to document tooth wear are reviewed here with an emphasis on nonhuman mammals, literature with which dentists may not be very familiar. We project a change in research strategy from the description of wear at various scales of measurement towards investigation of the mechanical mechanisms that actually create the

Gear wear process monitoring using a sideband estimator based on modulation signal bispectrum [PDF]
, 2017 As one of the most common gear failure modes, tooth wear can produce nonlinear modulation sidebands in the vibration frequency spectrum. However, limited research has been reported in monitoring the gear wear based on vibration due to the lack of tools ...
