Abstract

Objective: To compare the effects of zirconia high inlays and glass ceramic high inlays in the restoration of posterior teeth after root canal treatment. Methods: From April 2023 to August 2024, 90 patients who received posterior tooth root canal treatment were selected as research subjects. According to different treatment plans, patients were divided into two groups: one group used zirconia high inlays for restoration (zirconia group, 45 cases), and the other group used glass ceramic high inlays for restoration (glass ceramic group, 45 cases). The oral health status and restoration outcomes of the two groups were compared. Results: After 3 months of treatment in both groups, the GI and PLI scores of the zirconia group were lower than those of the glass ceramic group (P < 0.05). There was no signifi-cant difference in the integrity of the restorations between the two groups (P > 0.05). The pass rate of color matching in the glass ceramic group was higher than that in the zirconia group (P < 0.05), while the pass rates of marginal adaptation and gingival health in the glass ceramic group were lower than those in the zirco-nia group (P < 0.05). Conclusion: In the restoration of posterior teeth after root canal treatment, when comparing the repair effects of zirconia onlays and glass ceramic onlays, zirconia onlays are more conducive to maintaining oral health, with higher pass rates in marginal adaptation and gingival health. However, the glass ceramic group has a higher pass rate in color matching. Meanwhile, both types of restorations have good integrity.
