[Evaluation of the efficacy of Ceramage polymeric porcelain inlay and bulk block resin in the restoration of pulpless molars].

PURPOSE: To evaluate the efficacy of Ceramage polymeric porcelain inlay and bulk block resin in the restoration of pulpless molars.

METHODS

Sixty-eight patients with pulpeless molars admitted to the First Hospital of Yulin from March 2022 to December 2023 were selected, with 68 affected teeth. The patients were divided into the experimental group and the control group by the odd-even number method, with 34 cases in each group. The control group was repaired with bulk block resin, while the experimental group was repaired with Ceramage polymeric porcelain inlay. After 12 months of follow-up, the restoration effect and periodontal health indexes of the two groups were compared.

RESULTS

Six months after restoration, there was no significant difference between the two groups in terms of the color of restorations, marginal adaptation, marginal staining, restoration wear, restoration retention, secondary caries degree, proximal contact, gingival index(GI), plaque index(PI), tooth mobility and alveolar bone resorption(P＞0.05). At 12 months after restoration, there were no significant differences in the color, edge fit, edge coloration, restoration retention and proximity relationship between the two groups (P＞0.05). The wear of the prosthesis, the degree of secondary caries, PI and the degree of alveolar bone resorption in the experimental group were significantly lower than those in the control group (P＜0.05), and the load of tooth fracture resistance was significantly higher than that in the control group (P＜0.05).

CONCLUSIONS

The dental restoration effect of Ceramage polymeric porcelain inlay for pulpless molars is good, long-lasting and stable.
