Abstract:
Objective: the objective of this study was intended for evaluation of water sorption, solubility and pH of fluoride and strontium fluoride modified calcium silicate based cement.
Materials and Methods: A total of 40 samples were prepared and equally divided into three main groups (n=20 samples) according to materials used Group I: Calcium silicate based material (biodentine) is a control group, Group II: Strontium fluoride modified calcium silicate based material and Group III: Fluoride modified calcium silicate based material. Each main group was subdivided into two subgroups according to test type (n=20 sample) pH and water sorption and solubility test. Water sorption and solubility test is considered as one test and used the same samples
Results: According to water sorption and solubility test, biodentine recorded lowest water sorption and solubility followed by strontium fluoride modified biodentine followed by fluoride modified biodentine. According to pH, biodentine have high pH followed by fluoride modified biodentine then by strontium fluoride modified biodentine. Also pH value declined by time where (24 hrs > one week > four weeks)
Conclusion: There was no single modification that achieved all levels of improvement on tested properties so, from our result we can concluded that:
Modification of biodentine with strontium fluoride and fluoride have not considerable effect on the tested properties of biodentine.
Key Words: biodentine, physical properties, strontium fluoride, water sorption.
