Abstract:
ObjectiveTo investigate the influence of root resorption caused by orthodontic tooth movement,on gingival crevicular fluid (GCF) dentin sialophosphoprotein,DSPP,dentin sialoprotein,DSP expression.Methods67 patients admitted to hospital orthodontic patients as the clinical study,and according to different power values were divided into experimental group and control group,which had great value for the experimental group(300g) group and control group value for the normal force(30g) group,the two groups one week 12 weeks of its GCF DSPP,DSP expression were detected.ResultsIn the observation group DSPP,DSP expression was significantly higher than that in the control group,two groups of patients were in 7～9 weeks demonstrated increased,the observation group were(232 315 ±5437) gray,(487 876 ± 4374),(287 673 ± 5642),(212 147±2346) control group of gray scale,( 176 565 ±5327),(134 323 ± 2315 );and in 10 weeks after the reduction,the observation group 10 weeks and 11 weeks,(394 532 ± 4326),(287 674 ± 3235 ) ;the control group were( 87 876 ± 4323 ),(76 534 ± 3564),10 week 11 weeks were significantly reduced.ConclusionIn the process of root resorption in GCF DSPP,DSP changes in expression levels may be earlier than the X-ray results and the clinical manifestations,as it may cause root resorption of orthodontic tooth movement in the early detection of a target.
