The aqueous yellow ceramic ink was formulated by mixing distilled water and 15 vol% of the yellow ceramic pigment. The dispersion stability of the aqueous ceramic ink was characterized upon the addition of sodium dodecyl sulfate (SDS, Sigma Aldrich), polyacrylic acid (PAA, Mw 1800, Sigma Aldrich), poly(ethylene glycol) methyl ether methacrylate (PMEM, Mw 950, Sigma Aldrich), or PAA-g-PMEM, in which PAA was grafted with PMEM. The surfactants were added to the ceramic ink within the ranges of 0–1.0 mg m−2. To adjust the rheological properties of the aqueous ceramic ink, 0–15 wt% polyethylene glycol (PEG, Mw 8100, Sigma Aldrich) was added as a thickener and 0–0.1 wt% polysiloxane (BYK-028, BYK) was added as a surface tension modifier. A rotational rheometer (HAAKE MARS III, Thermo Fisher Scientific, USA) and surface tension analyzer (DST-60, Surface Electro Optics, Korea) were used to measure the viscosity and surface tension of the aqueous ceramic ink, respectively. The sedimentation behavior and dispersion stability of the pigment particles in the ceramic ink were analyzed quantitatively using Turbiscan (Turbiscan LAB, Formulaction, France). The hydrodynamic radius and surface charge of the pigment particles were analyzed using a particle size analyzer (VASCO, Cordouan, France) and a zeta potential analyzer (ELS-Z, Otsuka Electronics, Japan), respectively.

A remineralizing solution simulated body fluid (SBF) is composed of 136.8 mM NaCl, 4.2 mM NaHCO 3, 3.0 mM KCl, 1.0 mM K2HPO4•3H2O, 1.5 mM MgCl2•6H2O, 2.5 mM CaCl2, 0.5 mM Na2SO4. Composite discs were made by set white Portland cement powder and B A silanized silica 31) . This light-polymerizable hydrophilic resin blend can release calcium hydroxide (pH>9.25) to facilitate transformation of amorphous calcium phosphate (ACP) to carbonated apatite. Polyacrylic Acid (Mw 1800, Sigma-Aldrich; 1,000 ug/mL) and G4 PAMAM-COOH (Shangdong, China; 1,000 ug/mL) were respectively added to SBF to stabilize ACP as nanoprecursors 32, 33) . The dentin discs were divided into three groups (as shown in Fig. 1). The remineralizing solution was changed every day. After remineralization, the dentin discs were washed three times with deionized water and ultrasonicated for 10 min. To characterize the remineralization effects, these dentin discs were firstly checked by XRD and were then characterized by FE-SEM, EDS (INCA350, Oxford company, Oxford, UK) and TEM.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
