A device for manufacturing a brachytherapy array having a planar base which includes a working area comprising at least one planar major surface defining a first array of apertures, and a holding mechanism for holding a planar surgical mesh over the working area of said planar base. The method comprises delivering to a pocket of a tooth with periodontal disease, a viscous, reddish-brown solution comprising sulfuric acid and sulphonated phenolic compounds. At least one second beam is guided onto selected surface regions of the melt. The switching matrix spatially rotates the analog-to-digital converter outputs for storing such outputs in the memory element.
