| Abstract | ||
| Objective: This study was performed to assess and compare water sorption of three different bioactive restorative materials; Resin Modified Glass Ionomer (RMGI), giomer, and Activa bioactive composite at different time intervals in vitro. Materials and methods: 45-disc shaped specimens were prepared and divided into three equal main groups (n=15) according to the type of restorative material; RMGI (Fuji II LC), giomer (Beautifil II), and Enhanced RMGI (Activa bioactive composite), then immersed in deionized water. Each main group was divided into three equal subgroups (n=5) according to the storage period (1 day, 3 months and 6 months), specimens were subjected to drying cycles and weighed for water sorption measurement. Data analysis was performed using Two-way ANOVA test, post-hoc test, Kruskal-Wallis test and Dunn’s test. Results: After 24 hours; none of the three groups showed water sorption. After three and six months; there was a statistically significant difference between water sorption values in the three groups. Water sorption was statistically higher in Fuji II followed by Activa while Beautifil II showed the least one. Conclusions: RMGI, giomer, and Activa revealed water sorption values of accepted range in accordance with the ISO specification after 1 day, 3 months and 6 months storage periods. | ||
