Dental Materials Journal, 2013 We previously discovered that when a cone-shaped indenter coated with paint was pressed into an object, the paint disappeared in accordance with the depth of the indentation. Based on this fact, we developed the Cariotester, a portable system for measuring the Knoop hardness (KHN) of carious dentin.

Knoop Hardness of Self-Etch Adhesives Applied on Superficial and Deep Dentin
Journal of Dentistry, 2020 Statement of the Problem: Low pH of self-etch adhesives might cause suboptimal polymerization. Purpose: This study aimed to evaluate the effect of dentin depth (deep and superficial) on polymerization efficacy of two self-etch adhesives, with different

Effect of exposure time vs. irradiance on knoop hardness of dental composites
Materials Research, 2006 A comparison was made of the hardness of Z250 and Esthet-X composites light cured with different light sources. Cavities (3 mm diameter x 6 mm deep) were prepared in 240 bovine incisors. The composite was bulk inserted and light-cured using halogen light,
