초록
본 연구의 목적은 silorane-based 복합레진의 색안정성을 기존의 methacrylate-based 복합레진과 비교하여 평가하는 것이다. Silorane-based 복합레진인 P90(3M ESPE, USA), methacrylate-based 복합레진인 Tetric Ceram(Ivoclar Vivadent, Liechtenstein), Z250, Z350(3M ESPE, USA)을 이용하여 시편을 제작하고, 증류수, 커피, 레드 와인, 카레용액에 담가 1일, 3일, 7일, 14일, 21일, 28일 후 색 변화를 분광광도계로 측정하고 실험 전후의 색상차이(ΔE*ab)값을 산출하여 다음과 같은 결과를 얻었다. 1. 카레 용액 > 레드 와인 > 커피 > 증류수의 순으로 레진 시편의 변색이 크게 나타났다. 2. 네 가지 종류의 레진을 비교하였을 때, Z350 > Z250 > Tetric Ceram > P90의 순으로 변색이 크게 나타났다. 3. 카레 용액의 경우 네 종류의 레진 모두에서 침지 1일 이후 수용도 역치 이상(ΔE*ab>3.3)의 변색이 나타났다. 4. 레드 와인의 경우 Z350, Z250, Tetric Ceram에서 침지 1일 이후, P90에서는 침지 28일 이후에 수용도 역치 이상의변색이 나타났다. 5. 커피의 경우 Z350에서 침지 1일 이후, Z250에서 침지 3일 이후, Tetric Ceram에서 침지 7일 이후에 수용도 역치 이상의 변색이 나타났으나 P90에서는 침지 28일 이후에도 수용도 역치 이상의 변색이 나타나지 않았다.
Abstract
The objective of this study was to evaluate the color stability of new silorane-based composite resin compared with methacrylate-based composite resins after immersion in 3 staining solutions. One silorane-based composite(Filtek P90) and 3 methacrylate -based composites(Filtek Z250, Filtek Z350,Tetric Ceram) were evaluated. Twenty disk-shaped specimens(10×2mm) of each of 4 composite resins were prepared. The specimens were then divided into 4 groups of 5 specimens each and immersed in 3 staining solutions(coffee, red wine, curry solution) or distilled water(control) for 28-day test period. Color of the specimens was measured with a spectrophotometer(Color Eye 7000A) using CIE L*a*b* color space relative to CIE standard illuminant D65 at baseline, 1day, 3days, 7days, 14days, 21days and 28days after staining. The color differences(ΔE*ab) were calculated. The results were obtained as follows ;1. The mean color changes(ΔE*ab) of the composites were greatest in curry solution, then red wine, coffee and distilled water, in decreasing order. 2. The mean color changes(ΔE*ab) of the composites were greatest in Z350, Z250, Tetric Ceram and P90, in decreasing order.
