It has been suggested that patients should accept the use of the air abrasion technique over the conventional handpiece due to the reduced need for anesthesia. Technologies for both air abrasion and the conventional rotary handpiece have, in recent decades, seen major improvements, but there are no recent scientific publications that evaluate the patient's preference for these two technologies ...

The results are described of ongoing field and laboratory experiments to estimate losses from shingle beaches due to abrasion. Field abrasion experiments of two exotic lithologies (quartzite and limestone) used as tracers on two flint shingle beaches at Telscombe and Saltdean in East Sussex, UK, have been carried out over 23 months, resulting in 985 weight loss measurements. Relationships betwe...

OBJECTIVES To attain alliance between the oral hygiene practices with prevalence of tooth abrasion among urban and rural adult population of Central India. To plan dental care services in inaccessible areas and to suggest appropriate remedial measures to prevent this avertable and self-inflicted injury of teeth in this cross-sectional study. MATERIALS AND METHODS A sum of 1045 adult residents...

A study was conducted to determine whether the mandibles of the detrito-/bryophagous groundhopper Tetrix tenuicornis are subject to mechanical wear as a result of feeding, as is the case for grasshoppers that feed on silica-rich grasses. Abrasion was evaluated by measuring the length and width of the 3rd incisor and length of the 4th incisor in adults of different ages collected under natural c...

This study evaluated the effect of air-particle abrasion protocols on the biaxial flexural strength, surface characteristics and phase transformation of zirconia after cyclic loading. Disc-shaped zirconia specimens (Ø: 15mm, thickness: 1.2mm) (N=32) were submitted to one of the air-particle abrasion protocols (n=8 per group): (a) 50μm Al2O3 particles, (b) 110μm Al2O3 particles coated with silic...

Soil preparation tools are subject to severe abrasion. The wear resistance of various industrial components can be improved using the hardfacing technique. improvement in depends on microstructure, i.e., chemical composition alloys, method overlay, and parameters selected process. Plasma Transferred Arc with Powder (PTA-P) welding process is interesting as a technique since it promotes very low...

A chamberless, remote plasma deposition process has been used to coat silicon and plastic substrates with glass at ambient conditions. The films were deposited by introducing an organosilane precursor into the afterglow of an atmospheric plasma fed with helium and 2 vol% oxygen. The precursors examined were hexamethyldisilazane, hexamethyldisiloxane, tetramethyldisiloxane, tetramethylcyclotetra...
