Karies merupakan masalah kesehatan gigi yang umum dan sering ditangani dengan perawatan tumpatan. Resin komposit banyak digunakan karena sifat estetiknya yang memiliki berbagai pilihan warna, namun perbedaan tingkat warna tersebut dapat memengaruhi sifat mekanis bahan salah satunya kekerasan. Penelitian ini bertujuan mengetahui apakah terdapat pengaruh tingkat warna resin komposit packable nanohybrid produk Indonesia terhadap kekerasan permukaan.

Penelitian menggunakan resin komposit packable nanohybrid produk Indonesia (Replix Universal) tingkat warna A1, A2, dan A3 dengan sampel berbentuk silinder berdiameter 5 mm dan tinggi 2 mm, masing-masing terdiri atas enam sampel. Seluruh sampel disinari selama 20 detik menggunakan light curing unit, kemudian diuji menggunakan Vickers hardness tester dengan beban 100 gf selama 15 detik. Data dianalisis menggunakan uji One-Way ANOVA dan dilanjutkan uji Post-Hoc LSD.

Hasil penelitian menunjukkan bahwa terdapat perbedaan nilai kekerasan permukaan antara tiap tingkat warna. Nilai kekerasan tertinggi terdapat pada tingkat warna A1, A2, dan terendah pada A3. Hasil uji statistik menunjukkan bahwa tingkat warna berpengaruh signifikan terhadap kekerasan permukaan resin komposit (p < 0 name="_Hlk215342364">Universal warna A1, A2, dan A3 berpengaruh terhadap kekerasan permukaan, dengan warna A3 menunjukkan nilai kekerasan terendah.
