Abstract：Objective:To observe investigate the sealing effect of Green QrTM combined with Colgate anti-sensitivity toothpastel on dentin tubule,in order to provide theoretical basis for clinical treatment dentin hypersensitivity.Methods:A total of 84 newly extracted molars were collected.The dentin hypersensitivity model was prepared and then randomly divided into control group (n=12),Green QrTM group (n=24),Colgate anti-sensitivity toothpaste group (n=24),Green QrTM combined with Colgate anti-sensitivity toothpastea group (n=24).Twelve teeth out of each desensitizer group were selected for tooth brushing test.Occluding effect on dentinal tubules was observed by SEM,then the plugging rate of dentin tubules was statistically analyzed with SPSS 17.0 software package.Results:Dentin tubules in control group were completely open,while the exposed tubule was almost occluded in the Green QrTM group,Colgate anti-sensitivity toothpaste group and Green QrTM combined with Colgate anti-sensitivity toothpastea group.Among them,Green QrTM combined with Colgate antisensitivity toothpastea group displayed the best occlusion effect and demonstrated better occluding ability after the tooth brushing test.Conclustion:Green QrTM combined with Colgate anti-sensitivity toothpastea group were better in occludingability and abrasion resistance.
