Objective: To evaluate the effect of LED blue light on the viability, proliferation and morphology of periodontal ligament fibroblasts (PDLF). Materials and methods: Human PDLF cells were cultured and irradiated with LED blue light at different intensity and duration. MTT assay was used to determine the cytotoxicity and proliferation activity. Cell morphology was observed under light microscope. Statistical analysis was performed using ANOVA at a significant level of p
