LIVINGSTON, N.J., March 14 , 2011 /PRNewswire/ -- Milestone Scientific Inc. (Pink Sheets: MLSS) which develops, manufactures, and markets computer-controlled injection systems for medical and dental markets, today announced that its common stock has commenced trading on the OTCQB(TM) electronic quotation and trading system under the ticker symbol MLSS.PK.  Stockholders are not required to take any action as a result of the addition of the Company's securities to the OTCQB(TM).

The OTCQB(TM) marketplace was created in 2010 by Pink OTC Markets Inc. as a special tier of the OTC market to better distinguish companies that are registered and reporting with U.S. regulators from non-reporting companies.  Pink OTC Markets makes Real-Time Level 2 market maker quotations for all OTCQB securities available to investors on www.otcmarkets.com.  Pink OTC Markets Inc. now operates the leading electronic interdealer quotation and trading system and facilitates trading in over 9,000 securities not listed on a U.S. stock exchange.

The Company's securities are no longer being quoted by any market maker on the OTC Bulletin Board operated by Financial Regulatory Authority, Inc. (FINRA). The OTCBB(TM) is a quotation service for FINRA market makers and not an issuer listing service or securities market.

The OTCQB(TM) and the OTCBB(TM) are competing inter-dealer quotation systems. Although the securities of some companies are still quoted on both systems, there has recently been a substantial migration of trading volume from the OTCBB(TM) to the OTCQB(TM) for technology, cost, and service reasons. The OTCQB(TM) is widely viewed as superior to the OTCBB(TM) by market makers and issuers because the OTCBB(TM) does not support electronic trading and does not offer issuer services to its quoted companies.
