Effect of barium silicate on mechanical properties, transmittance, and protein adsorption of resin for additive manufacturing containing zwitterionic polymer. The Journal of Prosthetic Dentistry, 132(2), 465-e1.00223913http://dx.doi.org/10.1016/j.prosdent.2024.05.012https://hdl.handle.net/20.500.12713/6815Statement of problem: Studies on the effect of barium silicate on the material properties of additively manufactured (AM) resins containing 2-methacryloyloxyethyl phosphorylcholine (MPC) for dental applications are lacking. Purpose: The purpose of this in vitro study was to evaluate the mechanical properties, transmittance, and protein adsorption of MPC-containing AM resin incorporated with different barium silicate contents and to compare these findings with those of a commercially available unfilled AM resin marketed for definitive restorations. Material and methods: Resins incorporating 6 wt% MPC and 4 different concentrations of barium silicate (10 wt%, MB10; 20 wt%, MB20; 30 wt%, MB30; and 40 wt%, MB40) were prepared. An MPC-containing resin with no filler was also prepared (0 wt%, MBN). Surface roughness (n=15), Vickers hardness (n=15), flexural strength and modulus (n=15), fracture toughness (n=15), transmittance (n=15), and protein adsorption (n=3) of the filled resin specimens were measured and compared with those of commercially available unfilled resin specimens. All data were analyzed using the Kruskal–Wallis and Dunn tests (α=.05). Results: All experimental resins had higher surface roughness than the unfilled resin (P≤.048). MB40 had higher hardness, flexural strength, flexural modulus, and fracture toughness than most other groups (P≤.047). MB10 had higher transmittance than most other groups (P≤.012). All experimental resins had lower protein adsorption than the unfilled resin, regardless of the barium silicate content (P≤.023). Conclusions: The experimental resin containing 6 wt% MPC and 40 wt% barium silicate showed better mechanical properties and lower protein adsorption than the resin with no MPC or ceramic fillers. Transmittance decreased with the increase of barium silicate in the resins. © 2024 Editorial Council for The Journal of Prosthetic Dentistryeninfo:eu-repo/semantics/closedAccessAdsorptionBarium CompoundsDental MaterialsFlexural StrengthHardnessIn Vitro TechniquesMaterials TestingMethacrylatesPhosphorylcholinePolymersProteinsSilicatesSurface PropertiesArticle1322465.e1465.e8388900602-s2.0-8519636715910.1016/j.prosdent.2024.05.012Q1
