Abstract

The color stability of CAD-CAM ceramic veneer restoration is a crucial factor for the long-term success of the restoration. However, the effect of food spices on CAD-CAM ceramic has not been evaluated.  The purpose of this study was to evaluate the color stability of CAD-CAM laminate veneer materials after artificial aging and exposure to turmeric and paprika staining solutions. CAD-CAM ceramic slices (N=72; shade; A2; diameter 9 mm × 7 mm) were prepared using feldspathic ceramic (n=36) and zirconia-reinforced lithium disilicate (n=36). Each type of ceramic material is divided into two thicknesses, 0.5 mm (n=18) and 0.7 mm (n=18). The ceramic slices were cemented onto central incisors. The samples were subjected to accelerated aging for 1000 cycles. Samples were further divided into 3 subgroups (n=6): distilled water (control), turmeric, and paprika staining solutions, and soaked for 24 h. Spectrophotometric color measurement was recorded, and color difference (∆E) was calculated after aging (∆E1), and after 24 h of immersion in spices solutions (∆E2). Two-way analysis of variance and Bonferroni’s test were used for the statistical analysis (α=.05). ∆E1 means were not significantly influenced by ceramic materials (P=0.770) and thicknesses (P= 0.162). ∆E2 means were significantly affected by the interaction between thickness and staining solutions in both materials (P <0.05). Both ceramic veneers presented the highest color change after immersion in turmeric solution. Ceramic veneers show color changes after artificial aging. Turmeric shows a significant effect on the color of ceramic veneer after staining. Ceramic thickness influences the amount of color change after aging and staining.

Abstrak

Kestabilan warna pemulihan venir seramik CAD-CAM merupakan faktor penting untuk kejayaan jangka panjang pemulihan. Walau bagaimanapun, kesan rempah makanan pada seramik CAD-CAM belum dinilai. Tujuan kajian ini adalah untuk menilai kestabilan warna bahan venir lamina CAD-CAM selepas penuaan buatan dan pendedahan kepada larutan pewarna kunyit dan paprika. Kepingan seramik CAD-CAM (N=72; lorek; A2; diameter 9 mm × 7 mm) disediakan menggunakan seramik feldspathic (n=36) dan litium disilikat bertetulang zirkonia (n=36). Setiap jenis bahan seramik dibahagikan kepada dua ketebalan, 0.5 mm (n=18) dan 0.7 mm (n=18). Potongan seramik disimen pada gigi kacip tengah. Sampel telah tertakluk kepada penuaan dipercepatkan untuk 1000 kitaran. Sampel dibahagikan lagi kepada 3 subkumpulan (n=6): air suling (kawalan), larutan pewarna kunyit dan paprika dan direndam selama 24 jam. Pengukuran warna spektrofotometri telah direkodkan dan perbezaan warna (∆E) dikira selepas penuaan (∆E1) dan selepas 24 jam rendaman dalam larutan rempah (∆E2). Analisis dua hala bagi varians dan ujian Bonferroni digunakan untuk analisis statistik (α=.05). ∆E1 bermakna tidak banyak dipengaruhi oleh bahan seramik (P=0.770) dan ketebalan (P= 0.162). Purata ∆E2 telah terjejas dengan ketara oleh interaksi antara ketebalan dan larutan pewarnaan dalam kedua-dua bahan (P <0.05). Kedua-dua venir seramik memberikan perubahan warna yang paling tinggi selepas rendaman dalam larutan kunyit. Venir seramik menunjukkan perubahan warna selepas penuaan buatan. Kunyit menunjukkan kesan ketara pada warna venir seramik selepas pewarnaan. Ketebalan seramik mempengaruhi jumlah perubahan warna selepas penuaan dan pewarnaan.

Kata kunci: Kestabilan warna; rempah-rempah makanan; venir seramik CAD/CAM
