Influence of Surface Treatment on the Physical Properties and Biofilm Formation of Zirconia-Reinforced Lithium Silicate Ceramics: In Vitro Trial

POL promoted lower roughness and minor morphologic surface alterations, but biofilm formation and flexural strength were similar to the GL group. In general, ZLS-CD and ZLS-VS showed more similar behavior than LD, which makes ZLS glass-ceramic a good option for indirect restorations.
