THE INFLUENCE OF AN ACIDIC SOFT DRINK ON THE MICROHARDNESS OF DIFFERENT RESTORATIVE MATERIALS

Background and Aim: The aim of the present study was to evaluate the effects of an acidic soft drink on the microhardness of different restorative materials. Materials and Methods: One hundred twelve restoration samples, twenty-eight in each material group (Ketac Molar, Ketac Nano, Filtek Silorane and Filtek Z250), were prepared. After the baseline microhardness measurement, four experimental procedures were applied daily as follows: Group I, samples were immersed in a cola drink (Coca-Cola) for five minutes over five cycles; Group II, a remineralization agent (Tooth Mousse-GC) was applied as an additional step to the procedure for Group I; Group III, a cola drink was applied once a day for twenty-five minutes; and Group IV, the samples were kept in artificial saliva as a control. Following the treatment procedure (1, 7 and 30 days), the microhardness was re-measured, and the data were statistically analysed (p

BİR ASİDİK İÇECEĞİN FARKLI RESTORATİF MATERYALLERİN MİKROSERTLİĞİ ÜZERİNE ETKİSİ

Amaç: Bu çalışmanın amacı bir asidik içeceğin farklı restoratif materyallerin mikrosertliği üzerine etkisini incelemekti. Gereç ve Yöntem: Her bir materyal grubunda (Ketac Molar, Ketac Nano, Filtek Silorane ve Filtek Z250) yirmi sekiz adet olmak üzere toplam yüz on iki adet örnek hazırlandı. Başlangıç mikrosertlik ölçümü sonrası aşağıda belirtilen prosedürler günlük olarak uygulandı. Grup I; örnekler beş kez beş dakika kola (Coca-Cola) içerisinde bekletildi. Grup II; Grup I’deki işleme ek olarak bir remineralizasyon ajanı (Tooth Mousse-GC) uygulandı. Grup III; günde yirmi beş dakika kola uygulandı. Grup IV; kontrol grubu örnekleri yapay tükürük içinde bekletildi. Uygulamalar sonrası (1, 7 ve 30 gün) tekrar mikrosertlik ölçümü yapıldı ve veriler istatistiksel olarak analiz edildi (p
