Objective: We aimed to investigate the bioactivity and antibacterial effect of nitrogen plasma immersion ion implantation (PIII) on polyetheretherketone (PEEK).
Methods: According to the different modified parameters, the PEEK specimens were randomly divided into four main groups (n=49/group): PEEK-C, PEEK-I, PEEK-L, and PEEK-H. Then, N-PIII surface modification was conducted using the corresponding parameters.
Effects of light curing modes and ethanol-wet bonding on dentin bonding properties.

Objective: This study explored the effects of different light curing modes and ethanol-wet bonding on dentin bonding strength and durability.
Methods: A total of 54 molars were randomly divided into three groups: Single Bond 2, Gluma Comfort Bond, and N-Bond. Based on the three light-curing modes and presence or absence of ethanol pretreatment, the samples were assigned to six subgroups: high-light mode, ethanol pretreatment+high-light mode, soft-start mode, ethanol pretreatment+soft-start mode, standard mode, and ethanol pretreatment+standard mode.
