Purpose: The purpose of this study was to investigate the transmittance differences of zirconium core due to thickness within the visible light spectrum.
Methods: 36 specimens were divided into 3 groups (0.6 , 0.8 , 1.0 ) which have each 12 specimens. The size of specimens was 10 high and 10 wide. The transmittance of specimens are measured by spectrophotometer Model Cary 500 that can measure infrared-ray, visible wave and ultraviolet-ray.
Results: The results shows that there was no significant difference between specimen’ thickness and transmittance.
Conclusion: The individual's color perception is personal and there are numerous factors that influence on it. In general, human eye can perceive the color of thing only within visible light spectrum but in this experiment through spectrophotometer there was no big difference between specimen’ thickness and transmittance.
To sum up, The most important factors were a layed porcelain structure and its thickness rather than core thickness in the porcelain crown.
