ABSTRACT
Objective; To investigate the expression and distribution of IL-6 in periodontal tissues and the change of the alveolar bone of rats during orthodontic tooth movement, and to study the effects of orthodontic force on the periodontal tissue remodeling. Methods:
SO gram orthodontic force was loaded on the left first maxillary molars of 25 rats in experimental group. Immunohistochem-istry and histomorphometric analysis were performed to measure the expression of IL-6 and the loss of alveolar bone at 0, 1, 3, 5, 7 " and 10 days after the application of orthodontic force. Results; The expression of IL-6 was observed to reach maximum level on day 3 and to decline thereafter in experimental group. No obvious alveolar bone loss was detected in the mesial side of the first molars. Conclusion; Although orthodontic force can evoke the local inflammatory response of periodontal tissue and the expression of pro-inflammation cytokines such as IL-6, it can not cause severe periodontal destruction and alveolar bone loss.
