Abstract
Granules of a bioactive glass were implanted in a surgically created hole in a sheep's mandibular bone. After one year the bone with the glass was explanted, processed and examined under optical and scanning electron microscope. All particle were surrounded by a layer of minerilized tissue with histological features very similar to root cement; serial sections revealed that a small cementum bridge connected this mineralized tissue directly to root cementum. Under polarized light it was possible to observe oriented collagen fibers similar to the periodontal ligament inserting on the mineralized tissue.
