The Effect of Baking Soda and Vinegar on Tooth Wear

Current Research in Dental Sciences
Alternative products used for tooth whitening teeth cause serious wear on tooth surfaces. Knowing the factors that cause tooth wear and their localizations plays an important role in reducing risk factors and treatment.

Lifecycle wear prediction of spur gears with time-dependent Archard model and surface topography evolution

Results in Engineering
Gear wear degrades transmission accuracy by altering tooth geometry, contact pressure, and dynamic response. Many prediction approaches under dry/solid-lubricated conditions still under-represent the tribo-dynamic coupling among a time-dependent wear ...

Association of dietary habits and parental-reported sleep tooth grinding with tooth wear in children with mixed dentition

BMC Oral Health, 2017
Background Tooth wear has a multifactorial etiology, thus it should be assessed within a multiple-variable framework. The objective of this investigation was to assess the association of dietary habits and parental-reported sleep tooth grinding (STG ...

Trophic evolution in ornithopod dinosaurs revealed by dental wear

Nature Communications
Ornithopod dinosaurs evolved numerous craniodental innovations related to herbivory. Nonetheless, the relationship between occlusion, tooth wear rate, and tooth replacement rate has been neglected. Here, we reconstruct tooth wear rates by measuring tooth

Study on Tooth Wear of Spur Gears Under the Mixed Elastohydrodynamic Lubrication

Jixie chuandong, 2022
To study the wear evolution process and wear law of involute spur gears under the mixed elastohydrodynamic lubrication (EHL) and consider the lubrication conditions, thermal effects and load changes in the wear process of gear pairs, a wear model of gear

An effective prediction model for dynamic wear evolution of unmodified and modified helical gear pairs [PDF]

Mechanical Sciences
An effective dynamic wear prediction model for helical gear pairs considering tooth surface modification is established by deeply integrating the Archard wear model, the loaded tooth contact analysis (LTCA) model, and the lumped-parameter dynamic model ...

Study on the Time-varying Mesh Stiffness of Speed-increasing Gear Pair with Non-uniform Wear

Jixie chuandong, 2019
Taking an involute cylindrical speed-increasing gear pair as the research object, the tooth surface contact pressure and the relative sliding velocity are deduced to establish the non-uniform wear model of the spur gear pair based on the Hertz contact ...
