TI  - Dual cure luting composites--Part II: Clinically related properties.
PG  - 57-66
AB  - Thirteen dual cure luting composites were compared in function of film thickness, 
      consistency, and working time by using the American National Standard/American 
      Dental Association (ANS/ADA) specifications for zinc phosphate cement and direct 
      filling resins. The effect of temperature and setting reaction on the film 
      thickness was also evaluated for some representative products. All three 
      clinically related properties varied widely among the products investigated. A 
      strong linear correlation was found between film thickness and consistency. This 
      relation is supported by the temperature dependence of film thickness of dual 
      cure luting composites. Cooling of the material increased the consistency, 
      resulting in a larger film thickness, while heating reduced the film thickness 
      because of the lower consistency. However, one product with a rather short 
      working time at room temperature occasionally exhibited a dramatically enlarged 
      film thickness after heating, probably caused by accelerated chemical 
      polymerization. No correlation emerged between film thickness and maximum filler 
      size or between consistency and filler weight content. Maximum filler size and 
      filler weight content had been measured previously in Part I of this study. 
      Scanning electron microscope (SEM) analysis of the cured film thickness samples 
      revealed that the largest filler particles had been crushed under the heavy load 
      pressure during film thickness measurement. The lack of correlation between 
      consistency and filler weight content can be explained by the multifactorial 
      determination of the consistency. It is concluded that the great diversity in the 
      currently available luting composites makes clear specifications with regard to 
      the optimum composition of luting composites urgently needed. Furthermore, more 
      adequate methods for testing the film thickness of luting composites are also 
      required.
