Efficacy of Curodont in Managing Incipient Caries in Primary Teeth
… environment. Specimens were then sectioned, and Knoop microhardness values were measured and calculated (25gf; 10 sec) beginning 25 µm below the outer enamel surface and extending in 25 µm intervals to a depth of 225 µm. Using R software, a linear mixed-effects model was used to evaluate the …

Mechanical properties of a new zinc-reinforced glass ionomer restorative material
… molds followed by flattening and polishing. Knoop microhardness (KHN) was performed (25 g, 30 s),on pre-determined areas of the polished surfaces. For toothbrushing wear resistance and roughness, specimens were brushed in an automated brushing machine (200 g) with a suspension of dentifrice …

The effect of two bleaching products on microhardness and surface texture of different dental aesthetic restorative materials
… effect of two different bleaching agents on the microhardness and the surface texture of six different aesthetic restorative materials were evaluated. <br>Four different composite resins (a hybrid, a flow, a micro-hybrid and a nano-hybrid), an ormocer, and a ceramic, were used and two bleaching …

Evaluation of multiple and single emission peak light emitting diode light curing units effect on the degree of conversion and microhardness of resin-based pit and fissure sealant
… through the degree of conversion (DC) and Knoop microhardness (KHN) of a resin-based pit and fissure sealant at various light curing times and two distances compared to a single emission peak LED LCU. Method: Sixty disks of resin-based pit and fissure sealant (Delton, DENTSPLY, York, PA) …

Comparative Enamel Remineralization Using SDF, Fluoride Varnish, and Curodont™
… and evaluation included cross-sectional Knoop microhardness (CSMH) testing at depths of 25–225 µm to assess mechanical properties. Additionally, micro-computed tomography (micro-CT) was performed to assess lesion depth and evaluate the mineral density of each treatment group. CSMH data …

Dentin Remineralization Around Ceramir Restoration
… obtain highly polished dentin surface. Baseline Knoop micro hardness values were recorded. All specimens were then etched using 37% phosphoric acid for 5 seconds to demineralize dentin and to expose dentin collagen. The Knoop indenter micro hardness measurements were again performed for each …
