Abstract

Background: The bonding of cement materials to enamel and dentin may be affected by dimensional
changes which may be happened after water absorption of the cement when it is in water when the filling
used by the person. The aim of our research was to see how much water may be noticed inside prepared
cements compared with those with other traditional cements.
Method and materials: tow light-cured (1 and 2) and another two chemically-cured (4 and 5) were
prepared. Two types of cements used by the Iraqi dentists also used, first one light-cured (No.3) and the other
was chemically-cured (No.6) . Thirty samples were produced having 4mm height and 9mm diameter. Five
samples from each type of cement were prepared. Then we record the weight of each sample was recorded
after setting of the material before putting them in water using very. To remove water from the specimen
material a desiccator was used for one day. Samples were kept in water. After different immersing times of
5,10,15,30, and 60 minutes, one, three, seven, ten day, and fourteen the weight of each sample was recorded.
The value recorded for water absorbed was rounded to the nearest 0.1mg/cm2. Results: light-cured cements
absorb more water than chemical-cured cements. The highest value was noticed for cement (5) then for
cement number (2). The least value was noticed for cement number (3).Conclusion: cements cured by light
absorbed more water than chemically-cured cements. Modifying cement´s powder components showed no
effect on water sorption, while liquid chemical composition showed noticable effect on water absorbed
bythe tested cements
