Abstract:
Objective To compare the repair effects of resin super-porcelain inlays and cast porcelain onlays on posterior tooth defects after root canal treatment.Methods A total of 198 patients with posterior tooth defects(235 teeth)who were admitted to Zhenjiang Stomatological Hospital from February 2019 to March 2022 were selected and divided into study group(99 cases,116 teeth)and control group(99 cases,119 teeth)according to random number table method.After root canal therapy,the control group was repaired with resin super-porcelain inlays,and the study group was repaired with cast porcelain onlays.The repair result,periodontal index,complications and satisfaction were compared between the two groups.Results The success rate of repair in the study group was higher than that in the control group(93.10%vs.84.87%,P<0.05).The failure rate of repair in the study group was lower than that in the control group(5.17%vs.12.61%,P<0.05).There was no significant difference in the repair time or defect rate between the two groups(P>0.05).Twelve months after repair,sulcus bleeding index(SBI),gingival papilla index(PIS)and plaque index(PLI)were decreased in both groups(P<0.05),and these indexes in the study group were lower than those in the control group(P<0.05).There was no significant difference in the total incidence of complications between the two groups(P>0.05).The satisfaction rate of repair in the study group was higher than that in the control group(94.83%vs.81.51%,P<0.05).Conclusion Compared with the resin super-porcelain inlays after root canal treatment,the cast porcelain onlays has better repair effect.It can improve the satisfaction of patients and promote periodontal health with high safety and reliability.
