Characterization of the development of elasticity in dental luting cements Academic Article uri icon


  • The development of elasticity of dental luting cements was investigated as an indicator of working and setting time.A displacement rheometer was used to monitor the development of elasticity. Three luting cements were examined.The initial onset of elasticity in the glass-ionomer and polycarboxylate cements did approximate the manufacturer's quoted working times. The onset of elasticity did not appear to define a clinically useful working time for the zinc phosphate cement.The development of elasticity in luting cements as a measure of working time was not universally relevant. The demonstration of the presence of elasticity in some cements may have consequences for cementation and all ceramic crown systems.
