摘要
Abstract
BACKGROUND: More and more patients with periodontal disease require orthodontic treatments. Thus, the remodeling process and its mechanism of inflammatory periodontal tissues become a hot point during orthodontic tooth movement.OBJECTIVE: To observe the remodeling of inflammatory periodontal tissues during orthodontic tooth movement.METHODS: A total of 50 Sprague Dawley rats were randomly divided into the control and periodontitis groups. In the periodontitis group, rats were established periodontitis models. After that, all rats were prepared for orthodontic tooth movement models. The remodeling of periodontal tissues was observed by hematoxylin-eosin staining at 1, 3, 5, 7 and 14 days after orthodontic tooth movement.RESULTS AND CONCLUSION: The movement distance of the periodontitis group was greater than that of the control group. At 0-7 days after orthodontic force application, there was obviously bone resorption at the pressure side and the bone formation was inhibited at the tension side; at 14 days after force application, the bone resorption was diminished, associated with large numbers of multinucleated osteoclasts at the pressure sides in both groups. The findings showed that rats with periodontitis suffered more periodontal traumatism during orthodontic tooth movement, thus, treatment should be delayed until the inflammatory signs were controlled and the local inflammatory was eliminated.关键词
