Summary
This study evaluated the shear bond strength of a new 4-META adhesive cement to dentin and a nickel-chromium-beryllium alloy. The cement demonstrated a mean bond strength of 20.1 MPa, indicating good adhesion potential.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Adhesive Dentistry
Background:
- Dental adhesives are crucial for restorations.
- Evaluating new adhesive systems is essential for improving clinical outcomes.
- 4-META based cements offer potential for enhanced bonding.
Purpose of the Study:
- To determine the shear bond strength of a novel 4-META adhesive cement (C & B-Metabond).
- To assess the bond strength to both dentin and a nickel-chromium-beryllium (Ni-Cr-Be) alloy (Rexillium III).
Main Methods:
- Human molar teeth and Ni-Cr-Be alloy specimens were prepared to a 600 grit finish.
- Metal specimens were air abraded with 50-micron alumina.
- The 4-META cement was applied, and specimens were stored in water at 37°C for 24 hours before testing.
Main Results:
- The mean shear bond strength to dentin was 20.1 megapascals (MPa).
- The mean shear bond strength to the Ni-Cr-Be alloy was 20.1 megapascals (MPa).
Conclusions:
- The new 4-META adhesive cement exhibits promising shear bond strength to both dentin and Ni-Cr-Be alloy.
- This adhesive shows potential for use in dental restorations requiring bonding to tooth structure and metal alloys.
