title: Histological evaluation of surgically treated oral tissues after application of a photocuring periodontal dressing material. An animal study.
abstract: At present no information is available about biological effects on oral tissues of the photocuring periodontal dressing Barricaid. This animal study examines histologically the tissue responses of surgical areas covered during 7 days with either Barricaid, the eugenol-containing dressing Ward's Wondrpak or the bionert control gel Carboxyl Methyl Cellulose. One group was studied immediately after the removal of the dressings; in the other group, further healing was permitted for another week. Results after 7 days indicate acute inflammatory reactions in the test areas without significant differences between the 2 periodontal dressing materials. The control areas showed to a lesser degree basically the same tissue response. In the 2nd week, generally all areas healed. After 14 days, no differences between test- and control sites could be detected. From a biological point of view, these findings suggest no contra-indication for application of this photocuring dressing material after periodontal surgery.
