Pratiwi, RizkiWidya (2012) Pengaruh Lama Perendaman Terhadap Perubahan Warna Resin Komposit Nanohibrida Akibat Konsumsi Minuman Soda Aneka Warna dan Rasa. Sarjana thesis, Universitas Brawijaya.
Abstract
Resin komposit adalah material sewarna gigi yang saat ini diminati masyarakat sebagai bahan restorasi karena memiliki nilai estetik yang baik. Perubahan warna menjadi kendala yang membuat bahan tambal harus diganti sehingga tidak efisien. Minuman soda dikabarkan dapat menyebabkan perubahan warna pada resin komposit, namun belum ada penelitian secara jelas yang meneliti mengenai pengaruh lama waktu perendaman dalam soda aneka warna dan rasa terhadap perubahan warna resin komposit nanohibrida. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan antara perubahan warna resin komposit nanohibrida akibat perendaman dalam air mineral, soda lemon, soda strawberi, soda fruitpunch , dan soda jeruk dengan lamanya waktu perendaman. Metode yang digunakan pada penelitian ini adalah eksperimental laboratorik dengan menggunakan 100 spesimen resin komposit nanohibrida shade A3 berdiameter 5 mm dan tebal 2 mm yang direndam dalam air, soda lemon, soda strawberi, soda fruitpunch , dan soda jeruk selama 3, 7, 14, dan 21 hari dalam suhu 37 o C. Pengukuran perubahan warna menggunakan Spectrophotometer, Vita Easy Shade (Ultradents USA) dengan metode CIEL*a*b*. Hasil penelitian diuji secara statistik dengan uji repeated measures Anova untuk mengetahui pengaruh lama waktu perendaman terhadap perubahan warna resin komposit nanohibrida dan one way Anova untuk mengetahui perbedaan perubahan warna pada minuman soda aneka warna dan rasa. Hasil penelitian menunjukkan terjadi perbedaan perubahan warna secara signifikan terhadap lamanya waktu perendaman dan soda yang paling berpengaruh terhadap perubahan warna adalah soda strawberi dan soda fruitpunch . Kesimpulan dari penelitian ini adalah lamanya waktu perendaman mempengaruhi besarnya perubahan warna pada resin komposit nanohibrida, namun perubahan warna yang terjadi secara umum masih dapat diterima secara klinis ( Δ E≤3,3).
English Abstract
Resin Composite is a kind of tooth-colored material that is currently being the attention on the society to be used as a restorative material due to its high aesthetic value. The dicoloration becomes the constraint of its efficiency because the patchwork material needs to be replaced over times. Previous studies reported that soda can cause discoloration of the resin composite, but no studies have explicitly examined the effect of the length of the immersion time on the soda that has assorted colors and flavors that can cause the discoloration of nanohybrid resin composite. The objective from this study aims to determine the differences between the level of discoloration of nanohybrid resin composite due to its immersion in different kinds of drinks, such as: mineral water, lemon soda, strawberry soda, fruitpunch soda and orange soda, along with the length of the immersion time. The method used in this study is the experimental laboratory using 100 specimens of nanohybrid resin composite shade A3 with the diameter of 5 mm and a thickness of 2 mm which were immersed in water, lemon soda, strawberry soda, fruitpunch soda and orange soda for 3, 7, 14, and 21 days at 37°C. The color changes are measured using a Spectrophotometer, Vita Easy Shade (Ultradents USA) with CIEL*a*b* method. The results were statistically tested by ANOVA repeated measures test to determine the effect of the length of the immersion time on the discoloration of nanohybrid resin composite and one way ANOVA to know the different level on the discoloration of nanohybrid resin composite due to immersion on the soda that has assorted colors and flavors. The results showed that there were significance different level of discoloration of nanohybrid resin composite against time of immersion and the most affected soda due to the color change were strawberry soda and fruitpunch soda. The conclusion is resulted that the length of time of immersion affects the amount of discoloration of nanohybrid resin composite, but the color changes generally remain acceptable clinically (ΔE ≤3.3).
