Diskolorasi pada bahan restorasi giomer, seperti pada bahan restoratif berbasis resin lainnya disebabkan oleh faktor intrinsik dan ekstrinsik. Faktor ekstrinsik lebih dominan dibandingkan dengan faktor intrinsik. Tujuan penelitian ini adalah untuk mengetahui perbedaan kestabilan warna bahan restorasi giomer packable dan flowable terhadap larutan teh, kopi dan cola. Limapuluh enam sampel diskus giomer terdiri atas duapuluh delapan diskus giomer packable dan duapuluh delapan diskus giomer flowable berukuran diameter 20 mm dan ketebalan 2 mm masing-masing dibagi menjadi empat kelompok. Masing-masing kelompok terdiri dari tujuh diskus giomer. Diskus giomer tersebut diukur warnanya terlebih dahulu dengan chromameter sebelum dilakukan perendaman. Setiap kelompok tersebut direndam dengan larutan berwarna teh (kelompok II), kopi (kelompok III) dan cola (kelompok IV) serta aquades sebagai kelompok kontrol (kelompok I). Diskus giomer tersebut disimpan di dalam inkubator bersuhu 37oC selama tujuh hari dan larutan perendam diganti setiap hari dan kemudian dilakukan pengukuran warna akhir setelah perendaman. Perubahan warna diskus giomer diamati menggunakan chromameter kemudian dilakukan perhitungan perubahan warna (ΔE) yang didapatkan dari selisih warna awal dan warna akhir. Analisis data menggunakan uji anova dua jalur menunjukkan bahwa perbedaan jenis giomer (packable dan flowable) serta perbedaan jenis larutan perendam berpengaruh terhadap kestabilan warna setelah perendaman. Rerata perubahan warna (ΔE) giomer flowable menunjukkan hasil yang lebih rendah pada hampir semua jenis larutan perendam kecuali larutan kopi. Uji post hoc Tukey memberikan hasil diskolorasi oleh larutan teh berbeda secara signifikan dibandingkan dengan larutan kopi (α < 0,05), diskolorasi antara larutan teh dengan larutan cola berbeda secara signifikan (α < 0,05) dan diskolorasi antara larutan kopi dan cola juga berbeda secara signifikan (α < 0,05). Perbandingan diskolorasi antara kelompok larutan berwarna teh dan kopi dengan kelompok kontrol (aquades) memberikan hasil adanya perbedaan secara signifikan (α < 0,05) kecuali pada kelompok cola yang tidak berbeda secara signifikan (α > 0,05). Kesimpulan dari penelitian ini adalah giomer flowable yang digunakan pada penelitian ini lebih stabil terhadap perubahan warna ketika direndam dengan larutan berwarna kecuali larutan kopi.

Discoloration of giomer restorative material as in other resin based restorative material is caused by intrinsic and extrinsic factors. The extrinsic factor is more dominant compared to intrinsic one. The aim of this research is that to obtain color stability difference between packable and flowable giomer to the solutions of tea, coffee and cola Fifty six samples of giomer discs consist of twenty eight packable giomer discs and twenty eight flowable giomer discs with 20 mm of diameter and 2 mm of thickness. Each of it was divided into four groups and there were seven discs in every group. The color of samples was initially measured using chromameter before proceeds to immersion. Each of group was immersed in staining solutions which were tea (group II), coffee (group III) and cola (group III). Distilled water was used as a control group (group I). Giomer discs were kept on incubator which the temperature was previously set to 37o C for 7 days, staining solutions were replaced daily. In the end of the immersion, the samples were measured to obtain any change of color. The difference of the color was then used in determining color change (ΔE). The data was analyzed using two way anova. The result of the analysis indicated there was an influence in a matter of color stability related to different kind of giomer and staining solutions. Discoloration mean (ΔE) of flowable giomer after immersion showed a lower result compared to any other staining solution except coffee. Tukey test suggested there were significant differences between tea and coffee, tea and cola, coffee and cola (α < 0,05). Discoloration between staining solutions tea and coffee to distilled water appeared to be significant (α < 0,05), the only staining solution that was not significant compared to distilled water is cola (α > 0,05). The conclusion of this research is that, flowable giomer that is used in this research appeared to be more color stable to discoloration compared to packable giomer except in coffee solution.
