Effect of semiconductor laser combined with Dyract composite material in the restoration of sensitive wedge-shaped defects
Objective To explore the effect of semiconductor laser combined with Dyract composite material in the restoration of sensitive wedge-shaped tooth defects.Methods A total of 90 patients with sensitive wedging tooth defects who were treated in the Department of Stomatology,Wujin Hospital of Traditional Chinese Medicine of Jiangsu Province from June 2019 to June 2019 were selected and they were divided into the ex-perimental group and the control group according to the random number table method,with 45 cases in each group.The control group was treated with erbium-dopedyttrium aluminum garnet laser combined with Dyract composite material.The experimental group was treated with semiconduc-tor laser combined with Dyract composite material.The repair retention satisfaction after treatment were compared and periodontal tissue stress be-fore and after treatment were compared between the two groups.Cold air stimulation(visual analogue scale[VAS])was compared before treatment,immediately after treatment,4 weeks and 12 weeks after treatment.The total incidence of adverse reactions and the edge adhesion of the prosthesis were compared between the two groups.Results The proportion of satisfaction of restoration retention in experimental group was higher than that in control group(P＜0.05),and there was no statistical significance in color coordination and surface shape satisfaction between the two groups(P＞0.05).After treatment,the periodontal tissue stress at 30°,60°,and 90° in both groups were lower than those before treatment(P＜0.05).There was no significant difference in periodontal tissue stress at 30°,60°,and 90° between the two groups after treatment(P＞0.05).VAS scores of the two groups immediately after treatment,at 4 weeks and 12 weeks were lower than those before treatment(P＜0.05);VAS scores of experimental group were lower than control group immediately after treatment,at 4 weeks and 12 weeks(P＜0.05).There was no significant difference in the total inci-dence ofadverse reactions between the two groups(P＞0.05).The edge adhesion of the experimental group was better than that of the control group(P＜0.05).Conclusion Semiconductor laser combined with Dyract composites material in sensitive teeth wedge-shaped defect restoration can be improved edge or sex,restoration retention rate,improve air conditioning stimulus situation.
