a critical review of non carious cervical wear lesions and the role of abfraction erosion and Abrasion
Journal of Dental Research, 2006Co-Authors: David Bartlett, Punit ShahAbstract:The terms ‘abfraction’ and ‘Abrasion’ describe the cause of lesions found along the cervical margins of teeth. Erosion, Abrasion, and attrition have all been associated with their formation. Early research suggested that the cause of the V-shaped lesion was excessive horizontal toothbrushing. Abfraction is another possible etiology and involves occlusal stress, producing cervical cracks that predispose the surface to erosion and Abrasion. This article critically reviews the literature on Abrasion, erosion, and Abrasion, and abfraction. The references were obtained by a MEDLINE search in March, 2005, and from this, hand searches were undertaken. From the literature, there is little evidence, apart from laboratory studies, to indicate that abfraction exists other than as a hypothetical component of cervical wear.

surface conditioning influences zirconia ceramic bonding
Journal of Dental Research, 2009Co-Authors: Matthias Kern, A Barloi, Bin YangAbstract:Air-Abrasion seems to be mandatory for durable resin bonding to zirconia ceramic. Air-Abrasion might compromise the ceramic strength by creating surface defects. Therefore, omitting air-Abrasion or using reduced air-pressure seems desirable. We tested the null hypotheses that omitting air-Abrasion or using reduced air-pressure does not affect zirconia ceramic bonding independent of using primers. Three mechanical surface conditions (polished, air-abraded at 0.05 or at 0.25 MPa) and 4 priming conditions were tested. After different surface conditioning, zirconia ceramic specimens were bonded, and tensile bond strengths were evaluated after water storage for 3 days or for 150 days with additional 37,500 thermal cyclings for artificial aging. Omitting air-Abrasion resulted in debonding during artificial aging independent of using primers. The combination of air-Abrasion and priming improved long-term resin bonding to zirconia ceramic significantly. With low-pressure air-Abrasion, surface roughness was reduce...

effect of the single yarn twist and ply to single yarn twist ratio on the hairiness and Abrasion resistance of cotton two ply yarn
Autex Research Journal, 2006Co-Authors: Kolandaisamy Palaniswamy, Peer MohamedAbstract:The effect of single-yarn twist and ply to single-yarn twist ratio on the evenness, hairiness and Abrasion resistance of two-ply cotton yarn has been studied. The hairiness of two-ply yarn decreases as either the single-yarn or ply twist increases. The rate of reduction in hairiness with respect to twist is more for the single-yarn twist than for the ply twist, particularly for the finer two-ply yarn. Variation in hairiness decreases as the ply twist increases. Yarn-to-yarn Abrasion shows a different trend as compared to yarn-to-emery Abrasion at a low ply twist level. Two-ply yarn with 3/4 of the single-yarn twist shows the highest Abrasion resistance in both yarn-to-yarn Abrasion and yarn-to-emery Abrasion. The Abrasion resistance of the two-ply yarn depends on both single-yarn twist and ply twist. Single-yarn twist and ply twist have a more influential effect on the yarn-to-yarn and yarn-to-emery Abrasion resistances respectively of cotton two-ply yarns.
