Effect of different manipulations on the physical, chemical and microstructural characteristics of Biodentine

The water to powder ratio and method of mixing is important for the properties hydraulic cements. For this purpose a number clinicians prefer premixed materials. Dental manufacturing companies provide predosed materials, however manufacturer instructions are not always adhered to. aim research investigate physical chemical alterations tricalcium silicate?based cement Biodentine when manipulated according manufacturer’s (control) or changing doses material components. 6 groups were constituted different dosing liquid. hydrated cements characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) Fourier transform infrared spectroscopy (FT-IR). Calcium ion concentration leachate was also investigated. Assessment characteristics included setting time microhardness. Microstructural differences visible only in mixed manually with water, which early hydration rate affected, lower calcium release. Increase liquid increased release, but time. Manual manipulation required more (both liquid) added mixture guarantee similar consistency control. A decrease noted. All showed higher values microhardness at 24 h compared freshly set In there an overall all group control, particularly significant increasing dosage When Biodentine, altering procedure terms type amount device chosen has effect on physical, mechanical surface topography material, recommendations. Hence, should be strictly followed.
