Accounting Policies [Abstract]  
Consolidation, Policy [Policy Text Block]
Principles of Consolidation
The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and include the accounts of Milestone Scientific and its wholly owned and majority owned subsidiaries, including, Wand Dental (wholly owned), Milestone Advanced Cosmetic (majority owned) and Milestone Medical (majority owned). Milestone Education was a variable interest entity of which Milestone Scientific is the primary beneficiary and is consolidated into Milestone Scientific's financial statements. During
Milestone Scientific purchased the remaining
of Milestone Education in
September 2018,
increasing its ownership of Milestone Education to
 All significant, intra-entity transactions and balances have been eliminated in the consolidation.
Reclassification, Policy [Policy Text Block]
Certain reclassifications have been made to the
financial statements to conform to the consolidated
financial statement presentation. These reclassifications had
effect on net loss or cash flows as previously reported.
Use of Estimates, Policy [Policy Text Block]
  Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions in determining the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to the allowance for doubtful accounts, inventory valuation, and cash flow assumptions regarding evaluations for impairment of long-lived assets and going concern considerations, and valuation allowances on deferred tax assets. Actual results could differ from those estimates
Revenue Recognition, Policy [Policy Text Block]
   Revenue Recognition
Under ASC
the Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To perform revenue recognition for arrangements within the scope of ASC
the Company performs the following
identification of the promised goods or services in the contract;
determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract;
measurement of the transaction price, including the constraint on variable consideration;
allocation of the transaction price to the performance obligations based on estimated selling prices; and
recognition of revenue when (or as) the Company satisfies each performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC
The Company derives its revenues from the sale of its products, primarily dental instruments, handpieces, and other related products. The Company sells its products through a global distribution network and that includes both exclusive and non-exclusive distribution agreements with related and
Revenue from product sales is recognized upon transfer of control of a product to a customer, generally upon date of shipment. For certain arrangements where the shipping terms are FOB destination, revenue is recognized upon delivery. The Company has
obligation on product sales for any installation, set-up or maintenance, these being the responsibility of the buyer. Milestone Scientific's only obligation after sale is the normal commercial warranty against manufacturing defects if the alleged defective unit is returned within the warranty period. 
Sales Returns
We do
take returns from customer who do
have the right of return. Product returns under warranty are accepted, evaluated and repaired or replaced in accordance with the Company’s warranty policy. Returns
within the warranty policy are evaluated and the customer is charged for repair.
 Financing and Payment
Our payment terms differ by geography and customer, but payment is generally required within
days from the date of shipment or delivery.
Disaggregation of Rev
We operate in
operating segments: dental and medical. Therefore, results of our operations are reported on a consolidated basis for purposes of segment reporting, consistent with internal management reporting. See Note O for revenues by geographical market, based on the customer’s location, and product category for the years December
Consolidation, Variable Interest Entity, Policy [Policy Text Block]
Variable Interest Entities
A variable interest entity ("VIE") is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of a controlling financial interest. A VIE is consolidated by its primary beneficiary. The primary beneficiary has both the power to direct the activities that most significantly impact the entity's economic performance and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. 
If Milestone Scientific determines that it has operating power and the obligation to absorb losses or receive benefits, Milestone Scientific consolidates the VIE as the primary beneficiary. Milestone Scientific’s involvement constitutes power that is most significant to the entity when it has unconstrained decision-making ability over key operational functions within the entity.        
Because Milestone Scientific has a variable interest in Milestone China, it considered the guidance in ASC
“Consolidation” as it relates to determining whether Milestone China is a VIE and, if so, identifying the primary beneficiary. Milestone Scientific would be considered the primary beneficiary of the VIE if it has both of the following characteristics:
Power Criterion: The power to direct the activities that most significantly impact the entity’s economic performance; and
Losses/Benefits Criterion: The obligation to absorb losses that could potentially be significant or the right to receive benefits that could potentially be significant to the VIE
Milestone Scientific does
have the ability to control the activities that most significantly impact Milestone China's economics and, therefore, the power criterion has
been met. Management placed the most weight on the relationship and significance of activities of Milestone China to the CEO and a group of significant shareholders, including the Milestone China CEO, of Milestone China which have the power to direct the activities that most significantly impact the economic performance of Milestone China. Management has concluded that Milestone Scientific is
the primary beneficiary under ASC
Accordingly, Milestone China has
been consolidated into the financial statements of Milestone Scientific and continues to be accounted for under the equity method. See Note H.
Cash and Cash Equivalents, Policy [Policy Text Block]
Cash and Cash Equivalents
 Milestone Scientific considers all highly liquid investments purchased with an original maturity of
months or less to be cash equivalents.
Trade and Other Accounts Receivable, Policy [Policy Text Block]
Accounts Receivable
Milestone Scientific sells a significant amount of its product on credit terms to its major distributors. Milestone Scientific estimates losses from the inability of its customers to make payments on amounts billed. Most credit sales are due within
days from invoicing. There have
been any significant credit losses incurred to date. As of 
December 31, 2018
 accounts receivable was recorded, net of allowance for doubtful accounts of
Standard Product Warranty, Policy [Policy Text Block]
 Product Return and Warranty
Milestone Scientific generally does
accept non-defective returns from its customers, except for certain customers that can return factory sealed purchases (inventory) that still remain in their locations at the time of termination of their Distributor Agreement. Product returns under warranty are accepted, evaluated and repaired or replaced in accordance with the Warranty Policy. Returns
within the Warranty Policy are evaluated and the customer is charged for the repair.
Inventory, Policy [Policy Text Block]
Inventories principally consist of finished goods and component parts stated at the lower of cost (
-out method) or market. Inventory quantities on hand are reviewed on a quarterly basis and a provision for excess, slow moving, defective, and obsolete inventory is recorded if required based on past and expected future sales, potential technological obsolescence and product expiration requirements. As of
December 31, 2018 
inventory was recorded net of a valuation allowance for slow moving and defective inventory of approximately 
Equity Method Investments [Policy Text Block]
Equity Method Investments
Investments in which Milestone Scientific can exercise significant influence, but do
control, are accounted for under the equity method of accounting and are included in the long-term assets on the Consolidated Balance Sheets. Under this method of accounting, Milestone Scientific's share of the net earnings or losses of the investee is presented below the income tax line on the Consolidated Statements of Operations. Milestone Scientific evaluates its equity method investments whenever events or changes in circumstance indicate that the carrying amounts of such investments
be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period.
Property, Plant and Equipment, Policy [Policy Text Block]
  Furniture, Fixture and Equipment  
Equipment is recorded at cost, less accumulated depreciation. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets, which range from
years. The costs of maintenance and repairs are charged to operations as incurred. 
Intangible Assets, Finite-Lived, Policy [Policy Text Block]
  Intangible Assets – Patents and Developed Technology
Patents are recorded at cost to prepare and file the applicable documents with the US Patent Office, or internationally with the applicable governmental office in the respective country. The costs related to these patents are being amortized using the straight-line method over the estimated useful life of the patent. Patents and other developed technology acquired from another business entity will be amortized at the estimated useful life of the patent. These patents and developed technology are recorded at the acquisition cost. Patent defense costs, to the extent applicable, are expensed as incurred.                            
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]
Impairment of Long-Lived Assets
Long-lived assets with finite lives are tested for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset
be recoverable. The Company’s impairment review process is based upon an estimate of future undiscounted cash flow. Factors the Company considers that could trigger an impairment review include the following:
•           significant under performance relative to expected historical or projected future operating results,
•           significant changes in the manner of our use of the acquired assets or the strategy for our overall business
•           significant negative industry or economic trends
•           significant technological changes, which would render the technology obsolete
Recoverability of assets that will continue to be used in the Company's operations is measured by comparing the carrying value to the future net undiscounted cash flows expected to be generated by the asset or asset group. Future undiscounted cash flows include estimates of future revenues, driven by market growth rates, and estimated future costs. See Note J.
Cost of Goods and Services Sold, Shipping and Handling, Policy [Policy Text Block]
  Shipping and Handling Costs
Milestone Scientific includes shipping and handling costs, if any, in cost of goods sold. These costs are paid by or billed to customers at the time of shipments. Domestic and international shipments are FOB warehouse; therefore,
costs are incurred by Milestone Scientific.
Research and Development Expense, Policy [Policy Text Block]
  Research and Development
Research and development costs, which consist principally of new product development costs payable to
parties, are expensed as incurred. Advance payments for the research are amortized to expense either as services are performed or over the relevant service period using the straight-line method.
Income Tax, Policy [Policy Text Block]
  Income Taxes
Milestone Scientific accounts for income taxes pursuant to the asset and liability method which requires deferred income tax assets and liabilities to be computed for temporary differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.
December 31, 2018
we had
uncertain tax positions that required recognition in the consolidated financial statements. Milestone Scientific's policy is to recognize interest and penalties on unrecognized tax benefits in income tax expense in the Consolidated Statements of Operations.
interest and penalties are present for periods open. Tax returns for the
 years are subject to audit by federal and state jurisdictions. 
Earnings Per Share, Policy [Policy Text Block]
  Basic and diluted net loss per common share
Basic earnings (loss) per common share is computed by dividing the net earnings (loss) for the period by the weighted average number of common shares outstanding during the period. In periods where there is net income, we apply the 
-class method to calculate basic and diluted net income (loss) per share of common stock, as our Series A Convertible Preferred Stock is a participating security. The 
-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. In periods where there is a net loss, the 
-class method of computing earnings per share does
apply as our Series A Convertible Preferred Stock does
contractually participate in our losses. We compute diluted net income (loss) per common share using net income (loss) as the “control number” in determining whether potential common shares are dilutive, after giving consideration to all potentially dilutive common shares, including stock options, warrants, during the period and potential issuance of stock upon the conversion of our Series A Convertible Preferred Stock issued and outstanding during the period, except where the effect of such securities would be antidilutive.
The Company did
include any portion of outstanding options,  warrants or convertible preferred stock in the calculation of diluted loss per common share because all such securities are anti-dilutive for all periods presented. The application of the
-class method of computing earnings per share under general accounting principles for participating securities is
applicable during these periods because those securities do
contractually participate in its losses.
Since Milestone Scientific had net losses for
the assumed effects of the exercise of potentially dilutive outstanding stock options, warrants and convertible preferred stock were
included in the calculation as their effect would have been anti-dilutive. Such outstanding options and warrants totaled

Fair Value of Financial Instruments, Policy [Policy Text Block]
  Fair Value of Financial Instruments
Fair Value Measurements: Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market at the measurement date (exit price). We are required to classify fair value measurements in
of the following categories:
inputs which are defined as quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
inputs which are defined as inputs other than quoted prices included within Level
that are observable for the assets or liabilities, either directly or indirectly.
inputs are defined as unobservable inputs for the assets or liabilities.
Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of an input to the fair value measurement requires judgment and
affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]
  Stock-Based Compensation
Milestone Scientific accounts for stock-based compensation under ASC Topic
Share-Based Payment. ASC Topic
requires all share-based payments to employees, including grants of employee stock options, to be recognized in the Statements of Operations over the service period, as an operating expense, based on the grant-date fair values.
The fair value of the non-employee options was estimated on the date of grant using the Black Scholes option-pricing model. See note  L.
New Accounting Pronouncements, Policy [Policy Text Block]
  Recent Accounting Pronouncements
February 2016,

June 2016,
the FASB issued a new standard ASU
“Financial Instruments – Credit Losses” (Topic
).: The new standard is intended to replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. It will be effective for all entities for fiscal years and interim periods, beginning after
December 15, 2018.
Milestone Scientific will adopt this standard in
