| Summary: | The present pilot study aimed to determine the bond strength between dentin and two types of ceramics cemented using three types of luting agents.
The purpose of this pilot study was to determine the bond strength between dentin and two types of ceramics cemented using three types of luting agents.
Materials and Methods: Seventy-two dentin discs were prepared from extracted teeth with intact dental crowns. Ceramic cylinders of two types, lithium disilicate (IPS emax CAD) and hybrid Ceramic (Vita Enamic), were cut and sintered to dimensions of 6/6 mm. Test specimens (dentin – cement – ceramic) were distributed into six groups (n = 12), depending on the ceramic material used and the cement used for adhesive fixation (eCEMENT, Variolink Esthetic DC, Panavia V5). They were subjected to shear bond strength testing. The results were statistically analyzed using IBM SPSS Statistics 26 with a significance level of 0.05.
Results: In Vita Enamic, the highest shear bond strength was observed with Panavia V5 cement (18.87±0.89 MPa), followed by Variolink Esthetic DC (14.03±4.45 MPa) and e-CEMENT (11.40±5.19 MPa) (p < 0.05). In IPS emax CAD, the best bond was again with Panavia V5 cement (17.53±3.39 MPa), followed by Variolink Esthetic DC (17.30±4.49 MPa) and eCEMENT (14.33±5.27 MPa), however without statistical significance (p > 0.05).
Conclusions: Within the limitation of the presented study, the composite cement Panavia V5 demonstrates better adhesive properties than the other two types of cement. |
