组织工程修复及不同加力时间点对正畸移动牙牙周BMP 表达的影响
Effect of tissue engineering and different orthodontic force loading time on expression of periodontal BMP of orthodontic moved teeth
摘要
Abstract
Objective: To analyze the effect of tissue engineering and different orthodontic force loading time on expression of periodontai BMP of orthodontic moved teeth. Method: 20 New Zealand rabbits with chronic periodontitis were di-vided into two groups randomly. After tissue engineering and GTR therapy on the chronic periodontitis, the rabbits of one group (20-day group) were loaded orthodontic force on affected teeth 20 days later while the rabbits of another group were the control group. 30 days later all the animals were sacrificed and expression of BMP were analyzed. Result: Average expression of BMP of 20-day group was 4.522?.057, average expression of BMP of 40-day group was 4.321?.071, and average expression of BMP of the control group was 3.372?.051. Significant differences were found at each groups. Conclusion: The expressions of periodontai BMP were higher in groups with tissue engineering therapy than that of control group. The expression of periodontai BMP was higher in the 20-day group than that of the 40-day group.关键词
