Micro-CT was employed to analyze the differences in bone quantities of the mandibles between the two groups. Real-time fluorescence quantitative PCR (RT-qPCR) was used to examine the expression levels of osteogenic differentiation and metabolism-related genes in the cortical bone and condylar ossification center of the mandibles. Enzyme-linked immunosorbent assay was utilized to assess the diurnal variation of serum melatonin concentrations between the two groups. The artificial light at night experimental group received daily timed injections of a defined dose of melatonin to restore the diurnal variation of serum melatonin concentration in the mice, while the normal light group and the artificial light at night control group received the same volume of saline. Bone quantities, mandibular tissue morphologies, ossification differentiation in the condylar region and cortical bone, as well as glucose metabolism expression differences were assessed across the three groups. <b>Results:</b> The cortical bone thickness of the mandibles in the artificial light at night group [(0.196±0.017) mm] was significantly less than that in the control group [ (0.228±0.007) mm] (<i>P</i>=0.029). The bone volume fraction of the condylar ossification center in the artificial light at night group [(36.90±1.09) %] was significantly lower than that in the normal light group [(54.24±1.49) %] (<i>P</i><0.001). The length of the mandible in the artificial light at night group [(10.86±0.17) mm] was significantly shorter than that in the normal light group [(11.41±0.32) mm] (<i>P</i>=0.032).
