Abstract
This invitro study evaluated three dentine replacement materials: Biodentine, Ketac Molar and TheraBaseCa. Specimens of each material (n = 19) were prepared for investigations of hardness, calcium release, pH and water sorption-solubility. SEM and EDX analysis were also used for these investigations. One-way ANOVA and robust ANOVA tests were used for normally and non-normally distributed data for statistical analysis, respectively. TheraBaseCa showed the lowest hardness (p < 0.001), while Biodentine had the highest pH and calcium release (p < 0.001). Significant differences in water sorption-solubility were observed as Biodentine>Ketac Molar>TheraBaseCa (p < 0.001). SEM and EDX revealed that Biodentine had a crystalline structure with O, Ca, C, Si and Bi; Ketac Molar had a particulate matrix with O, C, F, Ca, Si and Al; and TheraBaseCa had a matrix with C, O, Si, Yb, Al and Ca. In conclusion, Biodentine was more alkaline and released more calcium, while TheraBaseCa had the lowest water sorption-solubility over 28 days.
