“…The results obtained in the present study as zero score for marginal adaptation were attributed to the butt-joint incisal configuration and preservation of a peripheral enamel layer around all margins, also, this design established an easy path of insertion of the laminate during bonding [30]. Najim et al [31] found that the CAD/CAM veneers with butt joint incisal reduction produced the most accurate margins while the least favorable combination was the pressable ceramic veneers with overlapped incisal reduction.…”

Objective: To evaluate fracture resistance and survival rate of IPS Empress CAD versus Polished Celtra Duo ceramic laminate veneers. Material and Methods: Thirty-six ceramic laminate veneers were fabricated for maxillary anterior teeth. The patients were divided into two groups according to the material Group 1(control group) fabricated from IPS Empress CAD laminate veneers and group 2(intervention group) fabricated from Polished Celtra Duo laminate veneers. Standardized the same preparation with butt joint design and chamfer finish line located supra gingival were performed for all the teeth. The fabrication of the veneers was performed using Cad\Cam (Ceramill motion) machine, with software (Exocad). The veneers surfaces were treated and silanated according to the manufacture instruction of each ceramic and enamel surfaces were etched where total etch adhesive protocol was obeyed using BISCO. Follow up sessions were done every two months up to one year for each patient using dental probe and operator vision to evaluate the fracture, survival rate, marginal adaptation, sensitivity and caries. according to USPHS criteria (United States Public Health Service). This was performed by an experienced, blinded investigator. Results: Fracture resistance, marginal adaptation, retention, caries and sensitivity were evaluated according to the criteria of USPHS and we found there is no significant difference as both groups scaled zero score. Conclusion: Both IPS Empress Cad and Polished Celtra Duo laminate veneers revealed successful clinical performance in terms of fracture resistance, marginal adaptation, retention, and sensitivity after one year follow up period.

Background: Coronal leakage is a significant cause of failure in endodontically treated teeth, and studies have reported the different effects of aqueous environments and occlusal forces on fiber-reinforced composite (FRC) materials. This study aimed to evaluate the effect of fiber post exposure on coronal microleakage in endodontically treated teeth restored with fiber post and composite core. Methods: Forty-five extracted maxillary incisors were sectioned at the CEJ, endodontically treated, and randomly divided into five groups. The specimens in the first group were restored with fiber post and core, but the post was not exposed and was covered with composite. The fiber posts were exposed in the second and fourth groups, while the fiber posts and luting cement were exposed in the third and fifth groups. The first, second, and third groups were varnished up to one millimeter below the CEJ, and the fourth and fifth groups up to the highest level of the composite core. The specimens were cut into two halves longitudinally with a diamond disc, and the depth of dye penetration was measured using a stereo microscope at the incisal and cervical interfaces. The Mann-Whitney U-test and Kruskal-Wallis test were performed to determine the significance of differences between the microleakage of different groups, with a significance level of 0.05. Results: The microleakage values of the groups with exposed fiber posts (fiber post-cement composite) did not differ. Due to the varnish coverage, the microleakage values in the cervical interface showed no significant difference in groups 1, 2, and 3, unaffected by post exposure at the incisal region. Conclusion: Fiber post exposure did not influence the microleakage values of endodontically treated teeth restored with fiber post-composite core buildup.
