M3-002 Microstructure and Microhardness of AISI 316L after Surface Mechanical Attrition Treatment

, 2009
Surface treatment is crucial for improving mechanical and physical properties of metals. This paper discusses the effect of surface mechanical attrition treatment (SMAT) on microhardness and microstructure of A ISI 316L. The polished samples were treated

Effects of organic solvents on the depth‐of‐cure determination of conventional and bulk‐fill resin composites

European Journal of Oral Sciences, EarlyView.
Abstract This study investigated the influence of organic solvents on the depth of cure (DOC) of resin composites. Two conventional (Filtek Universal [FU] and Beautifil II [BE]) and two bulk‐fill (Filtek One Bulk Fill [FO] and Beautifil‐Bulk [BB]) composites were evaluated.

Effect of chitosan‐containing desensitizers applied prior to bleaching on the physical properties of enamel

European Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the effects of adding chitosan (Chi) to desensitizing agents applied before dental bleaching on enamel properties. Bovine enamel specimens were allocated to seven groups (n = 12): no treatment (negative control), 2% NaF (positive control), 2% NaF + 2% Chi, 2% NaF + 5% Chi, 2% NaF + 5% KNO3, 2% NaF + 5% KNO3 + 2 ...

Phosphomimetic statherin‐derived peptide protects against intrinsic enamel erosion independently of sodium trimetaphosphate

European Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the effect of a phosphomimetic statherin‐derived peptide (DDSt15), alone or combined with sodium trimetaphosphate (TMP), on the protection against initial enamel erosion. A total of 102 bovine enamel samples (4 × 4 mm2) were prepared and randomly allocated into six groups (n = 17): deionized water (negative ...

Depth Of Cure And Microhardness Of Bulk-Fill Composites

International Dental Journal
Aim or purpose: This study aimed to compare a self-cured composite with three light-cure bulk-fill composites by assessing top and bottom surface microhardness values, and the depth of cure calculated through the bottom/top microhardness ratio (B/T ratio)
