Explanation:
Detailed explanation-1: -The hardest tissue in the entire human body is the enamel of our teeth. Dental enamel is greatly mineralized in its composition with approximately 92%–96% of inorganic matter, 1%–2% organic matter, and 3%–4% of water, weight/weight (w/w).
Detailed explanation-2: -However, unlike bone, cementum does not con-tain blood vessels, nerves, or haversian or Volkmann canals, which are the nutrient canals containing blood vessels and nerves in bone (see Fig. 10-3). Cementum is limited to the roots of teeth.
