Effect of Zirconia All-ceramic Crown in Restoration of Anterior Teeth and Influence on Local Inflammatory State
Objective:To investigate and observe the effect of Zirconia all-ceramic crown in restoration of anterior teeth and influence on local inflammatory state.Method:A total of 100 patients needed crown restoration of anterior teeth in Department of Stomatology,Shenzhen Longgang District Maternal and Child Health Care Hospital from January 2019 to January 2021 were selected as the study objects,and they were divided into control group(Ni-Cr alloy-ceramic crown group)and observation group(Zirconia all-ceramic crown group)by the random number table method,with 50 cases in each group.Then the restoration effect(color matching,integrity and edge tightness),incidence of adverse events,local inflammatory state indexes[gingival crevicular fluid inflammatory factors interleukin-1β(IL-1β)and interleukin-6(IL-6)and inflammatory mediators prostaglandin E2(PGE2)],inflammatory chemokines[regulated upon activation normal T cell expressed and secreted factor(RANTES)],satisfaction of patients between the two groups were compared.Result:The color matching,integrity and edge tightness of observation group were significantly better than those of control group,the incidence of adverse events was significantly lower than that of control group,there were statistically significant differences(P<0.05).Before treatment,the local inflammatory state indexes of two groups were compared,there were no statistically significant differences(P>0.05);after 3 and 6 months of treatment,the local inflammatory state indexes of observation group were significantly better than those of control group,the satisfaction of patient was significantly higher than that of control group,there were statistically significant differences(P<0.05).Conclusion:The effect of Zirconia all-ceramic crown in restoration of anterior teeth is better,and it can effectively control the local inflammatory state of patients,so it is more recognized by the patients.
