적색 LED에 관한 치과적 응용연구

Abstract

Phototherapy, the use of light for healing, has in recent years been a field of advanced multidisciplinary research. This modality has been shown to be beneficial in a wide and diverse range of maladies, including the healing of chronic and acute wounds as demonstrated by the use of laser light and LED (Light Emitting Diodes) technology. Red and near-infrared have beneficial effects on cells to creating more ATP (cellular energy) and increasing DNA and RNA activity. The aim of the present in vitro study was to evaluation the biological effects of Red light emitted by Red LED array on Normal Human Oral Keratinocyte (NHOK). Light intensities were measured with a radiometer. Cellular response to Red 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 cell viability.
