The glass ionomer cements developed by Wilson and Kent have several advantages such as fluoride release, adhesion to mineralized dental tissues and a coefficient of thermal expansion similar to that of tooth structure. In spite of so many favorable properties, its poor mechanical properties, limited indication range and low esthetic value led to the further development of resin-based composites. Cention N is an “alkasite” restorative material which like compomer or ormocer is essentially a subgroup of the composite material class. This new category utilizes an alkaline filler, capable of releasing acid-neutralizing ions. Aim: In order to select the best restorative material to restore carious tooth, this study compared the shear bond strengths of cention N and traditional glass ionomer cement. Material and Method: A total of 30 samples of GIC Type II and Centon N were examined to determine the shear bond strength. In a universal testing machine with a crosshead speed of 1 mm/min, sample cylinders with dimensions of 4 mm in diameter and 4 mm in height were bonded to the buccal surface of teeth to assess the shear bond strength. The data collected were tabulated accordingly and were subjected to statistical analysis using Statistical Package for the Social Sciences -version-22-(IBM SPSS Statistics.) Result: The values for shear bond strength of Cention N were statistically highly significant (P < 0.001) as compared to GIC Type II. Conclusion: Cention N presented with high shear bond strength and can be a good alternative to conventional glass ionomer cement.
