Abstract Guided Tissue Regeneration using collagen membrane was investigated by tetracycline fluorchrome labelling,which showed the dynamics of new alevolar bone and cementum formation.
Methods X-ray and CT findings of one patient with surgically and pathologically proved benign cementoblastoma(BCB)in left mandibular region were analyzed together with review of the literature.
If the gingiva recedes or plaque forms between the gingiva and the root, bacteria and acids have direct access to the cementum, which is much softer than enamel and dissolves more quickly.
Dental caries lesions typically form in an environment where there are lots of sugars in the mouth and a pH below 5.5 for enamel and below 6.2 to 6.8 for cementum and dentin.
