Content: The hardness between the 3 layers is quite consistent. At the base of the walrus tusks is the conical pulp cavity. The pulp cavity includes connective tissue and odontoblastic cells which are responsible for the formation of new walrus tusk material. The size and ultimate shape of the pulp cavity varies from animal to animal but is similar between the 2 walrus tusks of the same animal. Typically, the cavity is 2.5 - 4 cm (1 to 1.5") in depth, but can range from only 1 - 8 cm (0.5 to 3"). Fine longitudinal black cracks occur in the cementum of walrus tusks and on into the outermost portion of the primary dentine. These 'breathing cracks' are common on tusks, more on the outer rather than the inner side of the tusk and they occur only outside the gum line. The surfaces of the tusks aren't always absolutely flat. They can naturally grow in a convoluted shape with longitudinal dips and grooves which can enhance some applications. Tusks are formed on both the male and female walrus.
