Abstract

Abstract:
Objective: The objective of this study was aimed to evaluate the effect of incorporation strontium fluoride and fluoride on compressive and diametral tensile strengths of biodentine.
Materials and Methods:
Materials used in this study was divided into three main groups according to materials used Group I: Calcium silicate based material (biodentine) as a control material, Group II: Strontium fluoride modified calcium silicate based material, Group III: Fluoride modified calcium silicate based material. Each main group was subdivided into two subgroups according to test type (compressive and diametral tensile strength). Each subgroups dividing into two categories according to storage time at one week and one month.
Results:
According to compressive and diametral tensile strength test, biodentine recorded highest compressive and diametral tensile strength followed by strontium fluoride modified biodentine followed by fluoride modified biodentine. For storage time the four weeks compressive and diametral tensile strength is higher than Seven days.
Conclusion:
Modification of biodentine with strontium fluoride and fluoride don’t have considerable effect on the tested properties of biodentine.
Key Words: Biodentine, compressive strength, strontium fluoride, fluoride.
