Abstract：Objective: To explore the effects of glass-based all-ceramic crown,zirconia all-ceramic crown and fiber post core zirconia crown restoration on masticatory ability and gingival crevicular fluid inflammatory injury indicators in patients with posterior dental defects. Methods: A total of 151 patients (151 teeth) with posterior dental defects who underwent selective post-core restoration after root canal therapy were included in this study.They were divided into three groups based on the material used for crown restoration:Group A received glass-based all-ceramic onlay restoration,Group B received zirconia all-ceramic crown restoration,and Group C received fiber post core zirconia crown restoration.Baseline data were analyzed using propensity score matching to obtain balanced and comparable baseline data in each group.The restoration outcomes were evaluated one year after the procedure,and masticatory function (occlusal force,masticatory efficiency),periodontal status (gingival bleeding index,periodontal pocket depth,attachment loss),and gingival crevicular fluid inflammatory markers (interleukin-1β,alkaline phosphatase,prostaglandin E2) were compared before and after restoration.Complications were also assessed. Results: Group A had significantly higher rates of restoration integrity,color matching,edge suitability,edge coloring,and gingival condition compared to Groups B and C (P<0.05).One year after restoration,all three groups showed significant improvements in occlusal force and masticatory efficiency compared to before restoration (P<0.05).Group A exhibited significantly greater improvements in occlusal force and masticatory efficiency compared to Groups B and C (P<0.05),and Group B had significantly greater improvements than Group C (P<0.05).Gingival crevicular fluid inflammatory markers (BI,PD,AL) increased significantly in all three groups after one year of restoration (P<0.05).Group A showed significantly smaller changes in BI,PD,and AL compared to Groups B and C (P<0.05),and Group B had significantly smaller changes than Group C (P<0.05).Similarly,inflammatory markers (IL-1β,ALP,PGE2) in gingival crevicular fluid increased significantly in all three groups after one year of restoration (P<0.05).Group A exhibited significantly greater changes in these markers compared to Groups B and C (P<0.05),and Group B had significantly greater changes than Group C (P<0.05).The total complication rate in Group A within one year after restoration was 1.96%,significantly lower than the 12.00% in Group B and 18.00% in Group C (P<0.05). Conclusion: Glass-based all-ceramic onlay restoration,when used for posterior dental defects after root canal therapy,leads to improved restoration outcomes,enhanced masticatory function,reduced inflammatory injury indicators in periodontal tissue and gingival crevicular fluid,and a lower incidence of complications compared to zirconia all-ceramic crown and fiber post core zirconia crown restoration.
