Knoop hardness test - Diamond of rhombic shape (The long axis of indentotion is measured) The Knoop hardness test is used to obtain the values for both exceedingly hard and soft materials. The
Vickers (Diamond pyramid test) - Diamond of square base shape (The diagonal length of the indentation is measured)
Rockwell - Diamond of conical shape (The penetration depth is measured)
Brinells - Steel ball (The diameter of indentation is measured)
hardness value is independent of the ductility of the material.

RadiologyScreen films are specifically designed to be more sensitive to light than to X-rays. They work in conjunction with intensifying screens that convert X-ray energy to light photons. The film responds primarily to the light emitted by the phosphors in the intensifying screens, not directly to X-rays.

PhysiologyGastric acid secretion is inhibited by acidification of the stomach and duodenum. Low pH (acidity) in the stomach inhibits gastrin release from G cells, while high pH in the duodenum also contributes to the negative feedback mechanism that reduces acid secretion.

PeriodonticsThe circular fibers are part of the gingivodental group and are located in the marginal gingiva, encircling the teeth. In contrast, the alveolar crest, transseptal, and horizontal fibers are part of the periodontal ligament.

Giant cell tumors (GCTs) and giant cell granulomas (GCG) differ in the nuclear count of their giant cells. In GCTs, the giant cells have numerous nuclei (50-80), whereas in GCGs, the giant cells have fewer nuclei (3-20). Other features listed, such as uniform distribution, presence of inflammatory cells and IL, and small foci of spindle-shaped cells, can be similar in both conditions.
