The light transmissive dental matrix band is a dental matrix band for use in combination with a photoreactive dental filling material. The light transmissive dental matrix band includes a plate having opposed upper and lower ends, with a vertical slot formed through the plate and extending from the upper end towards the lower end, with at least one horizontal slot formed through a central portion of the plate and in open communication with the vertical slot. A layer of optically transmissive material coats the upper end of the plate, and a volume of the optically transmissive material fills the vertical slot and the at least one horizontal slot. The volume of the optically transmissive material is in optical communication with the layer of optically transmissive material coated on the plate's upper end. A tab, for grasping by the dentist, may be secured to the upper end of the plate.
