Histological evaluation of surgically treated oral tissues after application of a photocuring periodontal dressing material. An animal study.
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.
