Concentration Risk Disclosure [Text Block]	NOTE N-- CONCENTRATIONS Milestone Scientific has informal arrangements with third-party US manufacturers of the STA, CompuDent and CompuMed devices, pursuant to which they manufacture these products under specific purchase orders but without any long-term contract or minimum purchase commitment. Consequently, advances on contracts have been classified as current at December 31, 2021 and 2020. The termination of the manufacturing relationship with any of these manufacturers could have a material adverse effect on Milestone Scientific’s ability to produce and sell its products. Although alternate sources of supply exist, and new manufacturing relationships could be established, Milestone Scientific would need to recover its existing tools or have new tools produced. Establishment of new manufacturing relationships could involve significant expense and delay. Any curtailment or interruption of the supply, because of termination of such a relationship, would have a material adverse effect on Milestone Scientific’s financial condition, business, and results of operations. We had two customers that accounted for 20%, and 35% amount of revenue respectively for the year ended December 31, 2021. We had one customers that accounted for 39% amount of revenue respectively for the year ended December 31, 2020.
