Are mineralized bodies of cementum found either attached to the Cemental root surface or lying free in the periodontal ligament.

The human dentition, like those of most mammals, consists of two generations. The first generation is known as the deciduous (primary) dentition and the second as the permanent (secondary) dentition. The necessity for two dentitions exists because infant jaws are small and the size and number of teeth they can support is limited. . teeth..
