Are mineralized bodies of cementum found either attached to the Cemental root surface or lying free in the periodontal ligament. They form from the apposition of cementum around cellular debris in the periodontal ligament. Tooth development or . odontogenesis. is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth.
