مقایسه‌ی تأثیر نوشیدنی‌های مصرفی رایج، بر تغییر رنگ رزین‌های آکریلی گرماپخت

نوع مقاله : مقاله‌های پژوهشی

چکیده

مقدمه: هدف این مطالعه، بررسی و مقایسه‌ی تغییرات رنگ در 2 نوع رزین آکریلیک گرماپخت (ایوکلار و آکروسان) هنگام غوطه‌ور شدن در نوشیدنی‌های قهوه، چای و نوشابه بود.
مواد و روش‌ها: این مطالعه‌ی تجربی- آزمایشگاهی، شامل تهیه‌ی 60 نمونه رزین آکریلیک گرماپخت (ایوکلار و آکروسان، هر کدام 30 نمونه) بود و در بخش پروتزهای دندانی دانشگاه علوم پزشکی کردستان در سال 1402 انجام گرفت. نمونه‌ها به 3 زیرگروه تقسیم و به مدت 6 شبانه‌روز در محلول نوشیدنی‌های مورد آزمایش (چای 1 درصد، قهوه 1 درصد و نوشابه) غوطه‌ور شدند. نمونه‌ها توسط اسپکتروفتومتر بررسی و رنگ‌سنجی بر اساس سیستم CIE Lab انجام شد. داده‌ها توسط آزمون Kolmogorov-Smirnov و مدل Two-way ANOVA با آزمون Tukey's post-hoc تحلیل شدند. سطح معنی‌داری کمتر از 0/05 در نظر گرفته شد.
یافته‌ها: نتایج مطالعه نشان داد محلول‌های چای 1 درصد و قهوه 1 درصد باعث تغییرات رنگ قابل توجهی در نمونه‌های دو گروه شد. نمونه‌های گروه آکروسان تغییر رنگ کمتری را نسبت به گروه ایوکلار در مواجهه با هر سه نوشیدنی نشان دادند. میزان تغییر رنگ ناشی از نوشابه در هر دو گروه کمتر بود و گروه آکروسان عملکرد بهتری داشت.
نتیجه‌گیری: غوطه‌وری در نوشابه تغییر رنگ کمتری در هر دو گروه ایوکلار و آکروسان ایجاد کرد. نمونه‌های گروه آکروسان به طور معنی‌داری در مواجهه با هر سه نوشیدنی، دچار تغییر رنگ کمتری شدند. طبق شاخص NBS-units از لحاظ بالینی تفاوتی میان تغییر رنگ نمونه‌های دو گروه رزین آکریلی مشاهده نشد.

Comparing the Influence of Common Beverages on the Color Stability of Heat Cure Resin Acrylics

چکیده [English]

Introduction: The aim of this study is to investigate and compare the color changes in two types of heat-cure resin acrylics (Ivoclar and Acrosun) when immersed in common beverages such as coffee, tea, and soda for six days.
Materials and Methods: This experimental laboratory study involved the preparation of 60 heat-cure resin acrylic samples, with 30 from Ivoclar and 30 from Acrosun. The samples were divided into three subgroups and immersed in 200 ml of fresh solutions of one of the tested drinks (1% tea, 1% coffee, and soda) for six days and nights. The samples were then washed, dried, and examined using a solid reflective spectrophotometer. Colorimetry was performed based on the CIE Lab system.
Results: The study found that exposure to 1% tea and 1% coffee solutions caused significant color changes in both Ivoclar and Acrosun heat-cure acrylic samples. However, the Acrosun resin acrylic samples demonstrated less color change compared to the Ivoclar group when exposed to all three drinks. The amount of color change caused by exposure to soda for six days was less in both groups, with the Acrosun group performing better.
Conclusion: The study concludes that immersion in soda for six days caused less color change in both Ivoclar and Acrosun resin acrylic groups and had better performance. Acrosun resin acrylic samples experienced significantly less color change when exposed to all three drinks: 1%tea, 1% coffee, and soda. According to the NBS units index, no clinical difference was observed between the color change of the two groups of resin acrylic samples.
