Abstract
본 연구의 목적은 불소바니쉬 적용 후 심미수복재료의 색안정성을 평가해보는 것이다. 연구에 사용된 심미수복재료는 치과용 복합레진인 Filtek Z350 XT (3M ESPE, MN, USA), 자이오머인 Beautifil Flow Plus F00 (Shofu Inc., Kyoto, Japan), 레진강화형 글라스아이오노머 시멘트(RMGI)인 Fuji II LC (GC Co., Tokyo, Japan)이다. 각 심미수복 재료 당 30개의 시편을 제작하여 10개씩 3개의 군으로 나뉘었다. 대조군과 두 종의 불소바니쉬인 Cavity shield (3M ESPE, MN, USA)와 V-varnish premium (Vericom, Seoul, Korea)를 각각 적용한 군으로 설정하였으며, 가속시험을 위해 60 ℃의 증류수에서 30일간 보관하였다. 분광색채계측기를 이용하여 바니쉬 적용 전, 후 및 가속시험 15일, 30일 후 CIE L , a , b 값을 측정하여 색변화량(Δ E )을 산출하였다. 결과 값은 One-way anova로 비교 분석한 뒤 95% 유의수준에서 Tukey test로 사후 검증을 실시하였다. 실험 결과 모든 실험군에서 바니쉬 적용 후 색 변화가 관찰되었으며 그 중 RMGI의 ΔE 값이 다른 재료들에 비해 유의하게 크게 나타났다(p<0.05). 이후 가속시험에 따른 변화량은 바니쉬 적용군과 대조군에서 유의한 차이를 나타내지 않았다. 또한 Cavity shield를 적용한 giomer와 RMGI는 V-varnish를 적용한 군에 비해 더 많은 색 변화를 보였으나 통계적으로 유의하지는 않았다. 결론적으로 심미수복재료에 대한 불소 바니쉬의 적용은 색안정성에 영향을 미치며, 특히 RMGI 복합레진과 giomer에 비해 큰 색변화를 보여 임상 적용 시 주의가 필요하리라 사료된다.
The objective of present study was to compare the color stability of esthetic materials after application of fluoride varnishes. Esthetic restorative materials including composite resin (Filtek Z350 XT, 3M ESPE, MN, USA), resin modified glass-ionomer (RMGI, Fuji II LC, GC Co., Tokyo, Japan), and giomer (Beautifil Flow Plus F00, Shofu Inc., Kyoto, Japan) were used in this study. Cavity shield (3M ESPE, MN, USA) and V-varnish premium (Vericom, Seoul, Korea) were used as the fluoride varnishes. 30 samples of each restorative materials were prepared, which were divided into 10 each, among three groups. Group I were stored in distilled water, which were used as the control, Group II were applied with Cavity shield and Group III were applied with V-varnish premium. All specimens were stored in the distilled water at 60 ℃ for 30 days for the accelerated test. Samples were then subjected to colorimetric analysis. Data collected was statistically analyzed using one way ANOVA and Tukey's post-hoc test (p=0.05). The color change before and after application of varnish was observed in all experimental groups. Especially RMGI showed highest Δ * value (p<0.05). The color change according to the accelerated test showed no significant difference in the varnish application group and the control group. Giomer and RMGI applied with Cavity shield showed more color change than V-varnish applied group, despite no significant differences. Present study concludes that color stability of esthetic restoration materials can be affected by application of fluoride varnish. Especially, RMGI showed a large color change compared to the composite resin and giomer, which suggested that careful attention should be paid to clinical application.
