Objective: Surface properties of dental casts have critical importance in dental laboratory procedures. However, surface properties of the dental cast are affected by a lot of applications in dental laboratory. One of these applications is the slurry water immersion of the dental casts in some techniques such as preparing casts for duplication. Thus, the aim of the present study was to compare the effects of slurry water immersion and tap water immersion on the surface roughness of type III and type IV dental stones.
Method: 60 master stone blocks were prepared with type III and type IV dental stone. Half of the each specimen group was immersed in slurry water and the other half in tap water for 30 minutes. Each of four groups was then allowed to dry for 24 hours without any contamination to surface of stone blocks . The surface roughnesses of the specimens were determined using by a profilometer. The data were statistically analyzed using one-way analysis of variance (ANOVA).
Results: Specimens immersed in tap water showed statistically significant surface roughness (p<0.05) than those immersed in slurry water. The difference was more prominent between ADA type III dental stone groups.
Discussion: Slurry water dissolves the surface of gypsum cast less than tap water. Thus, within the limitations of the present study, to maintain the surface accuracy of the dental casts' slurry water immersion should be preferred instead of tap water.

Amaç: Alçı ile hazırlanan dental modellerin yüzey özellikleri, dental laboratuarda gerçekleştilen işlemler üzerinde önemli etkiye sahiptir. Bunun yanında dental modellerin yüzey özellikleri farklı uygulamalar sonucunda değişebilmektedir. Bu uygulamalardan birisi, dental modellerin çoğaltılması işleminde olduğu gibi, modellerin suda bekletilmesidir. Bu çalışmanın amacı, alçılı suda ve musluk suyunda bekletilen ADA tip III ve tip IV dental alçı ile hazırlanmış dental modellerin yüzey pürüzlülüğünün karşılaştırılmasıdır.
Yöntem: ADA tip III ve tip IV dental alçı kullanılarak 60 adet örnek hazırlandı. Her bir örnek grubunun yarısı alçı ile doygunluğa ulaşmış suda ve diğer yarısı musluk suyunda 30 dakika bekletildi. Sonrasında, örnekler yüzey kontaminasyonu olmayacak şekilde 24 saat kurumaya bırakıldı. Örneklerin yüzey pürüzlülükleri profilometre cihazı kullanılarak değerlendirildi. Verilerin analizi tek yönlü varyans analizi (ANOVA) kullanılarak değerlendirildi.
Bulgular: ADA tip III ve tip IV dental alçı ile hazırlanarak musluk suyunda ve alçılı suda bekletilen örneklerin yüzey pürüzlülüğü değerlerinin karşılaştırılması istatistiksel olarak anlamlı bulundu (p<0.05). Bu farklılık ADA tip III dental alçı ile hazırlanan örneklerde daha fazla olarak bulgulandı.
Sonuç: ADA tip III ve tip IV dental alçı ile hazırlanmış modellerin alçılı suda bekletilmesi, yüzey pürüzlülüğünü daha az etkilemektedir. Bu çalışmanın sınırları dahilinde, alçı modellerin yüzey özelliklerinin korunması için, modellerin musluk suyu yerine alçılı suda bekletilmesi önerilebilir.
