简要总结
After 15 years, 19 patients were available for clinical evaluation (recall rate: 56%). Kaplan-Meier analysis showed a cumulative survival of 78.1% for RXU+E and of 42.9% for RXU-E, indicating a significantly higher survival rate for RXU+E. Regarding clinical performance of PCC available for the 15-year evaluation, no statistically significant differences were observed between RXU+E and RXU-E using the modified USPHS and FDI criteria. Both groups showed significant deterioration in surface gloss, edge matching, and edge discoloration over time. RXU+E resulted in significantly worse anatomic shape over time and significant improvement in postoperative hypersensitivity compared with baseline.

入选标准
- •The patients were recruited from the patient pool of the Department of Operative Dentistry and Periodontology of the University of Regensburg. They were included in the study if
- •They were suffering from at least two large defects of the dental hard tissues suitable for the restoration with partial ceramic crowns. No initial carious lesions were treated. All defects were formerly insufficient amalgam or composite restorations.
- •The teeth to be restored did not reveal any symptoms of pain.
- •The application of rubber dam for the insertion of the restorations was possible.
- •Tooth mobility was lower than or equal to degree 1 (mobility of the tooth is discernible but not visible)
- •Additionally, all patients participating in the study exhibited a moderate level of oral hygiene represented by a papillary bleeding index (PBI) <35%
- •All patients were generally healthy and had no known allergies to the materials used.
排除标准
- •All issues contradicting the additional inclusion criteria.
