The dentine is known as ivory and its cross-section consists of crisscrossing line patterns, known as "engine turning", which create diamond-shaped areas.
For example, it takes an average of four to eight years for decay to progress from the tooth's outer layer (enamel) to the inner layer (dentine)," Evans noted.
This causes dentine to start showing – dentine has a dark yellow to brown color.
It consists mainly of dentine (inorganic formula Ca 10 (PO 4 ) 6 (CO 3 )·H 2 O)), one of the physical structures of teeth and tusks.
The base and crown of these are composed of dentine separated by an uncalcified layer and they are replaced at intervals.
