Influence of Different Cleaning Methods of Invisible Appliance on Periodontal Health of Patients with Malocclusion
Objective To investigate the effect of cleaning methods of invisible appliance on periodontal health of patients with malocclusion deformity.Methods A total of 60 patients with malocclusion deformity who were treated in the author's hospital from January 2021 to October 2021 were selected.All patients were treated with invisible appliance,and they were grouped according to the random number table method,with 20 cases in each group.In the control group,the invisible appliance was mechanically cleaned with a soft bristle toothbrush,a single bundle brush and fluoride toothpaste.On the basis of the control group,the invisible appliance in trial group 1 were soaked with Polidentt cleaning tablets twice a week for 30 minutes each time.On the basis of the control group,the invisible appliance in trial group 2 were soaked with chlorhexidine acetate solution twice a week for 30 minutes each time.The plaque index(PLI),gingival index(GI),probe depth(PD),sulcus bleeding index(SBI)and invisible appliance plaque index were compared among the three groups before treatment,1 month,3 months and 6 months after treatment.Results After 1 month of treatment,the invisible appliance plaque index in trial group 1 was lower than that in control group(P＜0.05).After 3 months of treatment,the gingival index and invisible appliance plaque index of trial group 1 were lower than those of control group(P＜0.05),and the invisible appliance plaque index of trial group 2 was lower than that of control group(P＜0.05).After 6 months of treatment,the gingival index,sulcus bleeding index and invisible appliance plaque index of trial group 1 were lower than those of control group,the gingival index and invisible appliance plaque index of trial group 2 were lower than those of control group(P＜0.05),the invisible appliance plaque index of trial group 1 was lower than that of trial group 2(P＜0.05).There was no significant difference in plaque index and probing depth among the three groups at different time points(P＞0.05).Repeated measurement analysis of variance showed that there were significant differences in gingival sulcus bleeding index,probing depth,gingival index and appliance plaque index before treatment and 1,3 and 6 months after treatment in the control group(P＜0.05).There were significant differences in the gingival index before treatment and at 1,3 and 6 months after treatment in trial group 1(P＜0.05).There were significant differences in the gingival index before treatment and at 1,3 and 6 months after treatment in trial 2 groups(P＜0.05).Conclusion Both Polidentt cleaning tablets and Chlorhexidine acetate solution can effectively remove the plaque in the invisible appliance,Polidentt cleaning tablets have better effect in maintaining periodontal health and convenient to use,which is worth to be popularized and used in clinical practice.
