Abstract

Objective Glass ionomers are preferred in many different treatment procedures in dentistry due to their positive features. The aim of this study is to evaluate the color difference and microhardness values of various glass ionomer cement after storing them in different solutions. Material and Method A total of 120 samples were prepared, including 40 of each of the Equia Forte, AHfil Silver, and Ionofil glass ionomers. Each glass ionomer sample was stored in distilled water, cola, tea, and coffee solutions. Color and microhardness measurements of the specimens were performed before and after a week before it was immersed in solutions. The color measurements of the samples were evaluated with a spectrophotometer and microhardness values were evaluated with Vickers microhardness device. For color analysis, color changes (ΔE) were calculated by obtaining the values of L*, a*, and b* of the samples before and after a week after being immersed in solutions. The data obtained were evaluated by variance analysis (ANOVA) and Tukey’s test. Results Except for specimens stored in cola for AHfil Silver, microhardness values were increased for all materials immersed in test solutions. The highest color change was obtained in coffee for Equia Forte, in the samples immersed in cola for AHfil Silver and Ionophil (p<0.05). The lowest color change was detected in samples stored in distilled water, and for Equia Forte and Ionofil, the color change was below the acceptable threshold value. Conclusion All the materials tested differ in microhardness and color change values after being immersed in the test environment. The increase in microhardness value can be attributed to the increasing maturation of glass ionomer cement over time, and color change can be attributed to the amount of yellow dyestuff contained in the solutions.

Özet

Amaç Cam iyonomer simanlar sahip oldukları olumlu özelliklerden dolayı diş hekimliğinde birçok farklı tedavi prosedüründe tercih edilmektedir. Bu çalışmanın amacı, farklı cam iyonomerlerin, farklı solüsyonlarda bekletildikten sonraki renk farkı ve mikrosertlik sonuçlarını değerlendirmektir. Gereç ve Yöntem Equia Forte, AHfil Silver ve Ionofil cam iyonomerlerin her birinden 40 tane olmak üzere toplam 120 örnek hazırlandı. Her cam iyonomere ait örnekler distile su, kola, çay ve kahve solüsyonlarında bekletildi. Solüsyonlara daldırılmadan önce ve bir hafta sonra örneklerin renk ve mikrosertlik ölçümleri yapıldı. Örneklerin renk ölçümleri bir spektrofotometre ile, mikrosertlik değerleri ise Vickers mikrosertlik cihazı ile değerlendirildi. Renk analizi için, solüsyonlara daldırılmadan önce ve bir hafta sonra örneklerin L*, a* ve b* değerleri elde edilerek renk değişimleri (ΔE) hesaplandı. Elde edilen veriler varyans analizi (ANOVA) ve Tukey’s testi ile değerlendirildi. Bulgular AHfil Silver için kolada bekleyen örnekler dışında, tüm materyaller için tüm sıvılarda bekletilen örneklerde mikrosertlik değerlerinde bir artış gözlendi. En yüksek renk değişimi Equia Forte için kahvede, AHfil Silver ve Ionofil için kolada bekletilen örneklerde elde edildi (p<0.05). En düşük renk değişimi distile suda bekletilen örneklerde elde edildi ve bu değerler Equia forte ve Ionofil için, kabul edilebilir renk değişimi eşik değerinin altındaydı. Sonuç Test edilen tüm materyaller, test ortamına daldırıldıktan sonra mikrosertlik ve renk değişim değerlerinde bir farklılık göstermiştir. Mikrosertlik değerindeki artış cam iyonomer simanların zamanla artan maturasyonuna, renk değişimi ise solüsyonların içinde bulunan sarı boyar madde miktarına atfedilebilir.
