AIM: To investigate the role of LPS in the odontoclast differentiation of MDPC-23 cells. It was hypothesized that MDPC 23 odontoblast-like cells may function as odontoclasts under the influence of LPS. METHODOLOGY: MDPC-23 cells were cultured in the presence of 0.1 or 1 μg/mL LPS for 6 days. Cell viability was determined using the CCK8 assay. TRAP staining, dentine resorption assay and ROS detection by confocal laser scanning microscope were used to test the odontoclast-like function of the induced cells...
