Abstract

Purpose: The aim of this study was to evaluate the influence of polishing methods on the color stability of composite resins. Materials and Methods: Two bulk-fill and four conventional resin composites were filled in cylindrical molds (6 mm diameter, 4 mm height) and light-cured. The specimens were stored in $34^{\circ}C$ distilled water for 24 h. Spectrophotometer was used to determine the color value according to the CIE $L^*a^*b^*$ color space. Each group was divided into three groups according to polishing methods (n = 5). Group 1 was control group (Mylar strip group), group 2 was polished with PoGo, and group 3 was polished with Sof-Lex Spiral wheels. Color evaluation was performed weekly for 4 weeks after immersion in $34^{\circ}C$ distilled water. The results were analyzed by generalized least squares method (P < 0.05). Results: Generalized least squares analysis revealed that Sof-Lex Spiral wheels group showed the significantly lower ${\Delta}E$ values compared to PoGo and control group (P < 0.05). The ${\Delta}E$ values of polished group showed the significantly lower than the ${\Delta}E$ values of unpolished group (P < 0.05). Regarding color changes of composite resins, there was no significant difference between the ${\Delta}E$ values of Filtek Z250 and Filtek Z350 XT Universal restorative in all time intervals (P < 0.05). Tetric N-Ceram Bulk Fill showed the significantly lower ${\Delta}E$ values compared to other composite resins in 1, 2, 3 weeks (P < 0.05). Conclusion: Within the limitations of this study, polishing methods influence the color stabilities of composite resins. The group polished with Sof-Lex Spiral Wheels showed more resistance to discoloration than group polished with PoGo.

목적: 복합레진의 색조안정성에 있어서 연마가 영향을 주는지 알아보았다. 연구 재료 및 방법: 2 개의 벌크필 레진과 4개의 복합레진을 6 mm 너비, 4 mm 높이로 제작하여 광중합한 후 $34^{\circ}C$ 멸균 증류수에 24 시간 보관하고 분광광도계를 이용하여 CIE $L^*a^*b^*$ 값을 측정하였다. 시편을 연마 방법에 따라 대조군(Mylar strip 그룹), PoGo로 연마한 그룹, Sof-Lex Spiral wheels로 연마한 그룹으로 나누었다(n = 5). 색측정은 4 주 동안 매주 시행하였고 실험 기간 동안 시편은 $34^{\circ}C$ 멸균증류수에 보관하였다. 실험결과는 일반최소자승법으로 통계분석하였다(P < 0.05). 결과: 일반최소자승법 분석에 따르면 Sof-Lex Spiral wheels로 연마한 그룹의 ${\Delta}E$ 값이 PoGo로 연마한 그룹과 대조군의 ${\Delta}E$ 값보다 낮게 나타났다(P < 0.05). 복합레진을 연마한 그룹의 ${\Delta}E$ 값은 연마하지 않은 대조군의 ${\Delta}E$ 값보다 낮게 나타났다(P < 0.05). 복합레진 비교시 Filtek Z250과 Filtek Z350 XT Universal restorative는 모든 기간에서 통계적 차이가 나타나지 않았으며 Tetric N-Ceram Bulk Fill은 1, 2, 3주에서 통계적으로 낮은 ${\Delta}E$ 값을 나타냈다(P < 0.05). 결론: 이번 연구의 한계점을 감안하면 연마 방법은 복합레진의 색조안정성에 영향을 미친다. Sof-Lex Spiral wheels로 연마한 그룹이 PoGo로 연마한 그룹보다 변색에 더 큰 저항을 보여주었다.
