护牙素对正畸牙面脱矿修复的临床效果观察OACSTPCD

Objective To evaluate the efficacy of Tooth Mousse on reducing enamel demineralization after orthodontic treatment of fixed appliance. Methods A self-controlled trial was carried out in the 30 patients who suffered from enamel demineralization after orthodontic treatment of fixed appliance. All tho patients( including 382 teeth ) were randomly divided into control group and experimental group,each group including 191 teeth. Experimental group was treated with Tooth Mousse for 3 minutes once a week. One treatment course was 4 weeks, and a patient should be treated for 12 weeks. No drug was used in the control group. The enamel demineralization was observed before treatment,in the first,second and third treatment course,respectively. Results The enamel demineralization index ( EDI) declined in the two groups after the first 4-week treatment,and the decrease was more significant in the experimental group than that in the control group(P =0. 000 );In the experimental group,EDI showed no signiftcant difference between the second treatment course and the first one( P = 0. 063 ), as well as between the second treatment course and the third one( P = 0. 171 ). Conclusion TooLh Mousse can reduce enamel demineralization after orthodontic treatment of fixed appliance,which is worthy of clinical application.
