Introduction:
We evaluated the water absorption, solubility, and compressive strength of different cements and resin-modified glass ionomer cements (RMGICs), namely Adhesor®, Ketac(™) Cem, Ortho Band Paste LC(™), Glass Ionomer Band Cement, and Transbond(™) Plus. Our aims were to compare the mechanical and physical properties of the cements widely used in orthodontics and to define the most suitable cements in an oral environment in terms of those characteristics.
Materials And Methods:
To assess compressive strength, the cements were subjected to compression tests done on a universal testing machine. To test water absorption and solubility, the weight changes in cement specimens were determined after immersion in distilled water for 1, 7, and 30 days.
Results:
Adhesor® and Ketac(™) Cem presented significantly higher solubility values than other cements after water immersion for 1, 7, and 30 days (p < 0.001).
Conclusion:
Our results revealed that the traditional orthodontic cements have higher water solubility and water absorption values as well as lower compressive strength values than the RMGICs used in this study. Furthermore, Transbond(™) Plus revealed the highest compressive strength, whereas Adhesor® showed the lowest.

Strength of Cement
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...
Types of Cement I
Type I (Ordinary Portland Cement) is widely used for general construction where special properties are not required. It has moderate sulfate resistance and heat of hydration.
Type II (Modified Cement) offers moderate resistance to sulfate attack and a lower rate of heat development compared to Type I. It is suitable for structures in...
