RE: CMU3 Dental Ozone Unit
Refer to CPT1200332 when replying to this letter.
Dear Ms. Budeau:
The Food and Drug Administration (FDA) has learned that your firm is marketing the CMU3 Dental Ozone Unit in the United States (U.S.) without marketing clearance or approval, in violation of the Federal Food, Drug, and Cosmetic Act (the Act).
Under section 201(h) of the Federal Food, Drug and Cosmetic Act, 21 U.S.C. § 321(h)
, this product is a device because it is intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or to affect the structure or function of the body.
The device is adulterated under section 501(f)(1)(B) of the Act, 21 U.S.C. § 351(f)(1)(B)
, because your firm does not have an approved application for premarket approval (PMA) in effect pursuant to section 515(a) of the Act, 21 U.S.C. § 360
e(a), or an approved application for an investigational device exemption under section 520(g) of the Act, 21 U.S.C. § 360
j(g). The device is also misbranded under section 502(o) of the Act, 21 U.S.C. § 352(o)
, because your firm did not notify the agency of its intent to introduce the device into commercial distribution, as required by section 510(k) of the Act, 21 U.S.C. § 360(k)
. For a device requiring premarket approval, the notification required by section 510(k) is deemed satisfied when a PMA is pending before the agency. 21 CFR 807.81(b)
. The kind of information that your firm needs to submit in order to obtain approval or clearance for the device is described on the Internet at
. The FDA will evaluate the information that your firm submits and decide whether the product may be legally marketed.
Additionally, under section 510 of the Act, 21 U.S.C. § 360
, manufacturers of medical devices are required to annually register with the FDA. In September 2007, section 510 of the Act was amended by the Food and Drug Administration Amendments Act of 2007 (Pub. L. 110-85) to require domestic and foreign device establishments to submit their annual establishment registration and device listing information to FDA by electronic means [section 510(p) of the Act, 21 U.S.C. § 360(p)
] during the period beginning October 1
and ending December 31
of each year. Our records indicate that your firm has not fulfilled annual registration and listing requirements for fiscal year 2012. Therefore all of your firm’s devices are misbranded within the meaning of section 502(o) of the Act, 21 U.S.C. § 352(0)
, in that the devices were manufactured, prepared, propagated, compounded, or processed in an establishment not duly registered under section 510 of the Act, 21 U.S.C. § 360
, and were not included in a list required by section 510(j) of the Act, 21 U.S.C. § 360(j)
Your firm should take prompt action to correct the violations addressed in this letter, including an immediate end to distribution of the CMU3 Dental Ozone Unit. Failure to promptly correct these violations may result in regulatory action being initiated by the FDA without further notice. These actions include, but are not limited to, seizure, injunction, and civil money penalties. Also, federal agencies may be advised of the issuance of Warning Letters about devices so that they may take this information into account when considering the award of contracts.
Please notify this office in writing within fifteen business days from the date you receive this letter of the specific steps your firm has taken to correct the noted violations, as well as an explanation of how your firm plans to prevent these violations, or similar violations, from occurring again. Include documentation of the corrections and/or corrective actions (including any systemic corrective actions) that your firm has taken. If your firm’s planned corrections and/or corrective actions will occur over time, please include a timetable for implementation of those activities. If corrections and/or corrective actions cannot be completed within fifteen business days, state the reason for the delay and the time within which these activities will be completed. Your firm’s response should be comprehensive and address all violations included in this Warning Letter.
Please direct your response or any questions you may have to: LCDR Cesar A. Perez, Ph.D., Acting Chief, Dental, ENT, and Ophthalmic Devices Branch, Center for Device and Radiological Health, Food and Drug Administration, 10903 New Hampshire Avenue, WO66 Rm 1561, Silver Spring, MD 20993. If you have questions concerning the contents of this letter, you may contact Dr. Perez at (301) 796-5770, or you may forward a facsimile to his attention at (301) 847-8137, or email him at
Finally, you should know that this letter is not intended to be an all-inclusive list of your firm’s violations. It is your firm’s responsibility to ensure compliance with applicable laws and regulations administered by FDA. Your firm should investigate and determine the causes of the violations and take prompt actions to correct the violations and bring your firm’s products into compliance.
