Abstract (2. Language): 
The microhardness of two different types of fissure sealant materials was investigated in this study. The sealants studied consists of resin based material and glass ionomer cement. The two classes of materials, namely resin and cement, differed markedly in their behaviour. The micro-hardness of the resin based material appeared to increase with time but this effect was offset by the plasticizing action of absorbed water during storage. The microhardness of the glass ionomerfissure sealant was found to decrease over the time. There was statistically high significant values between the microhardness of different type of fissure sealants. The different microhardness values are thought to be due to the differences in the chemical structure of the two materials.

Abstract (Original Language): 
Bu çalışmada farklı yapıda iki fissür örtücü materyalinin mikrosertlikleri incelenmiştir. Çalışma kapsamına alınan örtücüler reçine esaslı ve cam İyonomer esaslı materyallerdir. Reçine ve siman olarak isimlendirilen bu iki farklı materyalin yapısı gibi polimerizasyonu da farklılık göstermektedir. Reçine esaslı materyalin mik-rosertliği zaman içerisinde artmaktadır ancak, bu etki saklama sırasında emilen olan suyun plastisize hareketi ile dengelenmektedir. Cam iyonomer esaslı fissür örtücünün mikrosertliği zaman içinde azalmaktadır. İki farklı yapıdaki fissür örtücünün mikrosertlik değerleri arasında istatistiksel olarak ileri derecede anlamlı farklılık saptanmıştır. Mikrosertlîk değerlerindeki bu fark¬lılığın iki materyalin kimyasal yapısındaki farklılıklardan kaynaklandığı düşünülmektedir.
