Blue light is used in dental practise to cure resin-based materials, but the path of the light often includes oral tissues. A few studies have investigated the impact of blue light exposure on oral cells. The aim of the present in vitro study was to evaluation the biological effects of blue light emitted by blue LED array on Normal Human Oral Keratinocyte (NHOK). Light intensities were measured with a radiometer. Cellular response to blue light exposure was assessed by the observation of cell morphology and the cell mitochondrial activity (MTT assay). Results showed no differences between exposed- and non-exposed cells in regards to cell morphology and MTT assay.
