[Periodontal function after replantation]

The components of periodontal connective tissue were studied on days 28-30 after replantation of the teeth with the extra-alveolar time 5, 15, and 30 min. The levels of collagen, glucosaminoglycanes, sialic acids, and activity of sialidase increased at extra-alveolar time 30 min by 44, 33, and 20, and 85%, respectively. Introduction of potassium hyaluronate in dental wells reduced the sail collagen growth in the periodontal tissue.
