31. Dentin and cementum are more susceptible to caries than enamel because they have lower mineral content. 32. Fibroblasts are involved developing the periodontal ligament which connect teeth to the alveolar bone through cementum . 33. They are involved in adult regeneration of the periodontal ligament, alveolar bone, and cementum . 34. The tooth is held in location by a periodontal ligament, with the assistance of cementum . 35. Thus again, cementum is more similar to alveolar bone, with its osteoblasts becoming entrapped osteocytes. 36. Cementum is capable of repairing itself to a limited degree and is not resorbed under normal conditions.37. The origin of the formative cementoblasts is believed to be different for cellular cementum and acellular cementum. 38. The origin of the formative cementoblasts is believed to be different for cellular cementum and acellular cementum . 39. Nonetheless, it is known that cellular cementum is usually not found in teeth with one root. 40. It is this part which is attached to the cementum of the roots by the periodontal ligament.
