Dear Michael Kaminski:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be avare that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for

{2}------------------------------------------------

devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

#### PERFORMANCE DATA

#### Biocompatibility Testing

Biocompatibility was demonstrated consistent with FDA guidance "Use of International Standard ISO 10993-1. Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process".

#### Non-Clinical Bench Testing

Comparative chemical and physical property data for the subject and predicate device support a finding of substantial equivalence in terms of pH, specific gravity, surface tension and viscosity.

Shelf life stability testing provides for a 24-month shelf life of the subject device.

#### Clinical Testing

A controlled, randomized, 3-treatment, 3-period crossover clinical study was conducted to evaluate if Oral-B® Dry Mouth Oral Rinse and a marketed dry mouth rinse were more effective in relieving dry mouth symptoms, immediately and four hours after use, compared to water on day 1 and after four days of product use. The results of this study demonstrated that Oral-B® Dry Mouth Oral Rinse was more effective than water at providing immediate dry mouth moisturization and overnight and long-term relief of dry mouth symptoms. Analysis of the pilot study results support the Indications for Use statement of duration of effectiveness for up to 4 hours. Additionally, the data suggest that Oral-B® Dry Mouth Oral Rinse may be more effective than the comparator dry mouth oral rinse device.

### CONCLUSION

Based on the intended use, technological characteristics, non-clinical performance data and the clinical data provided the subject device is as safe, as effective, and performs as well as the legally marketed predicate device (K181134).
