PERUBAHAN WARNA BAHAN MAHKOTA SEMENTARA RESIN AKRILIK SWAPOLIMERISASI SETELAH KONTAMINASI LARUTAN KOPI DAN PENYIKATAN DENGAN PASTA GIGI PEMUTIH
Abstract
cara yang efisien untuk mengatasi masalah ini. Namun, kandungan bahan abrasif pasta gigi pemutih juga dapat mempercepat degradasi bahan mahkota sementara sehingga memengaruhi stabilitas warna bahan mahkota sementara. Tujuan dari penelitian ini adalah untuk mengetahui perubahan warna bahan mahkota sementara resin akrilik swapolimerisasi seteleh kontaminasi larutan kopi dan penyikatan dengan pasta gigi pemutih. Rancangan penelitian ini merupakan eksperimental laboratoris dengan sampel penelitian berupa bahan mahkota sementara resin akrilik swapolimerisasi, berbentuk silindris (diameter 15±1 mm, ketebalan 2,5 mm) yang diuji dengan colorimeter. Data dianalisis menggunakan wilcoxon range test. Hasil menunjukkan nilai yang signifikan antara perubahan warna setelah kontaminasi kopi dan penyikatan dengan pasta gigi pemutih pada bahan mahkota sementara resin akrilik swapolimerisasi dengan nilai signifikansi p=0,005 (p<0,05). Kesimpulan penelitian ini terdapat perubahan warna bahan mahkota sementara resin akrilik swapolimerisasi setelah kontaminasi larutan kopi dan penyikatan dengan pasta gigi pemutih.
