Solubility of Four Dental Luting Cements

Solubility is an important feature in assessing the clinical durability of luting cements.Solubility may cause degradation of the cement, leading to debonding of the restoration andrecurrent decay. The aim of this study was to evaluate and compare water solubility values of lutingresin cement with other three conventional luting cementsFour commercial dental luting cement materials were selected: GIC cement (SPOFADENTAL a.s ,Markova 238), Zinc polycarboxylate cement (SS White Group.P.C.I,Unit 9 MadleazeEstate, Bristol Road, England), Zinc Phosphate cement (SPOFA DENTAL a.s Praha, Cernok.) andResin cement (Densply Caulk 38 West Clarke Ave,U.S.A). Ten disc specimens were prepared foreach cement material using a stainless steel mold with 10 mm in inner diameter and 2 mm inthickness. Water solubility of different cement materials were calculated by weighting the samplesbefore and after water immersion (15 days) and desiccation. Data were analyzed by one-wayANOVA and Student t-test at 5% level of significance.Statistical analysis of data by using one-way analysis of variance (ANOVA) revealed that,there was statistically significant difference (P<0.05) in solubility values between the four lutingcements being tested.Resin cement has the highest resistance to solubility in comparison with other conventionalluting cements.
