Shear bond strength evaluation of new computer-aided design – computer-aided manufacturing chromium-cobalt alloy (Sintron) with two different types of cement: An in vitro study
Background: Any deficiency or problem in the shear bond strength between restoration and tooth surface can lead to recurrent decay, gingival issues, and associated esthetic concerns. Cement acts as a material to bond restorations to the tooth surface, filling the void space between the tooth and the...

| description | Background:
Any deficiency or problem in the shear bond strength between restoration and tooth surface can lead to recurrent decay, gingival issues, and associated esthetic concerns. Cement acts as a material to bond restorations to the tooth surface, filling the void space between the tooth and the restoration to establish this bond. This study aims to investigate the bonding strength of two common types of cement – polycarboxylate and zinc phosphate – with Sintron alloy (chromium–cobalt) in dental restorations.
Materials and Methods:
This research is conducted in vitro on 24 Sintron alloy discs cemented with two types of polycarboxylate (Poly-F, Dentsply, US) and zinc phosphate cement (Harvard Cement, Germany) on 24 extracted maxillary central incisors. Teeth were sandblasted with 50-micrometer aluminum oxide (Al2O3) particles. Disc-shaped alloy specimens with specific dimensions were prepared. The specimens were then bonded to the teeth surface using each cement and were subjected to shear bond strength testing using a Universal Testing Machine (Instron, 3367, Canton, MA, USA). An independent sample t-test was performed with P value significance of lower than 0.05.
Results:
The t-test with P = 0.150 showed no significant difference between the zinc phosphate and polycarboxylate cement groups.
Conclusion:
The study found no statistically significant difference in the bond strength of Sintron alloy when using zinc phosphate and polycarboxylate cement. Therefore, it can be concluded that the bond strength is similar for both cements. |
