ANATOMY

Detailed explanation-1: -A thick dentin layer forms the bulk of dental mineralized dental tissues. Dentin is capped by a crown made of highly mineralized and protective enamel, and in the root, it is covered by cementum, a structure implicated in the attachment of the teeth to the bony socket.

Detailed explanation-2: -Beneath the enamel, making up the bulk of the tooth is dentine and within the centre is the pulp cavity.

Detailed explanation-3: -Dentin is approximately 55 vol% mineral, 30 vol% organic material (primarily type I collagen), and 15 vol% fluid [46], but dentin composition varies with the age and tooth type.

Detailed explanation-4: -Bulk of teeth in mammals is made up of dentine. Dentine is the part of tooth between enamel and pulp. It surrounds the pulp cavity. Dentine is the main supporting structure of the tooth and is the second hardest tissue in the body after enamel.
