title: The Effect of Dental Adhesive on Final Color Match of Direct Laminate Veneer (DLV): In Vitro Study.
abstract: OBJECTIVE
  To evaluate the influence of dental adhesive on the color match of direct laminate veneer.
  
  
  METHODS
  Specimens were prepared in the form of discs. B1 nano-filled composite Filtek Z-350 XT (3M-ESPE) and single-bond universal adhesive were used. Twenty discs of each test group with a diameter of 10 ± 0.1 mm and thickness of 0.7 ± 0.1 mm were prepared. The specimens were divided into three groups: control group that has composite material only (C), a group that has adhesive with composite material (AC), and a group that has adhesive with composite and re-bonding technique (ACR). The samples were placed in viewing port for color measurement. Spectrophotometer was used in this study. Descriptive statistical analysis was performed for the CIE L*, a*, and b* values. Statistical software IBM SPSS 16.0 was used for analyzing the data, with a significance level of 0.05 (p < 0.05).
  
  
  RESULTS
  In this study, both groups where bonding agent was applied had significant change in color of the samples (p < 0.05). AC and ACR showed a change along the "a" coordinate and the "b" coordinate with using adhesive and re-bonding technique. There were significant differences when comparing the values of a* and b* of the control group C with AC group and ACR on using adhesive and re-bonding technique. ACR specimens presented the lowest "L" value.
  
  
  CONCLUSIONS
  Within the limitations of this study, despite the fact that the change of color is not extensive, the dental adhesive changes the color of direct composite restoration in a way that may warrant caution. Additional studies are essential to substantiate the findings of this study.
  
  
  CONCLUSIONS
  Dental adhesive play an important role in changing the color of direct composite restoration.
