Abrasion by a blade scraper compared with abrasion by a rough surface

A SANDBLAST ABRASION TEST FOR SYNTHETIC AGGREGATE EVALUATION by James

The need tor an aggregate abrasion test which effectively differentiates between the quality of aggregates of various unit weights prompted the development of a new test apparatus. The method selected uses air-driven sand as the abrading mechanism. Research findings based on tests of five natural and forty-seven synthetic aggregates tentatively indicate that the sandblast test is statistically ...

Whistle Abrasion: A Case Report

Abrasion is the physical wearing of a tooth surface which can involve the presence of a foreign object repeatedly being in contact with the tooth. A 40-year-old male patient reported to our dental clinic with a 2-3 mm uneven gap between his upper and lower front teeth on occlusion. A detailed history revealed that he was a physical education teacher, and the habitual placement of the whistle fo...

Dental abrasion as a cutting process.

A mammalian tooth is abraded when a sliding contact between a particle and the tooth surface leads to an immediate loss of tooth tissue. Over time, these contacts can lead to wear serious enough to impair the oral processing of food. Both anatomical and physiological mechanisms have evolved in mammals to try to prevent wear, indicating its evolutionary importance, but it is still an established...
