Abstract
Purpose: To clinically evaluate the performance of lithium disilicate endocrowns and overlays, restoring root canal treated molars for one year. Methods: A total of 50 restorations, 25 overlays (group O) and 25 endocrowns (group E), were fabricated to restore root canal treated molars. All restorations were fabricated from lithium disilicate (IPS e. max CAD). After tooth preparation, digital impression was done followed by designing, milling and cementation of the restorations. Evaluation was done every 3 month for 12 months by three independent assessors using Modified USPHS criteria. Statistical analysis of collected data was performed with SPSS 20®️, Graph Pad Prism®️ and Microsoft Excel 2016. Results: Regarding fracture and marginal adaptation, all restorations in both groups had Alpha score (100%); at base line and during the follow-ups. While for retention, all restorations in both groups had Alpha score (100%); at base line, after 3, 6, and 9 months. However, after 12 months, there was insignificant difference between both groups (P=0.08) as Alpha was (87, 100%) while Charlie was (13, 0%) regarding Group O & E respectively. Conclusion: Within the limitations of this study, e.max overlays showed good performance compared to e.max endocrowns for the restoration of endodontically treated teeth, after one year of clinical evaluation. E.max overlays represent a dependable restorative modality for endodontically treated molars.
