## Intended Use
Professional cleaning of teeth: Removal of subgingival and supragingival plaque-biofilm and stains Professional cleaning of teeth including patients with dentin hypersensitivity Treatment of dentin hypersensitivity by blockage of the dentin tubules Can also be used in the presence of fixed orthodontic devices (brackets), restorative and prosthetic materials, and implants For maintenance in periodontitis therapy after completion of initial treatment - when using standard devices - for gingival pockets up to 5 mm in depth For maintenance in perimplantitis therapy after completion of initial treatment - when using standard devices - for gingival pockets up to 5 mm in depth
## Device Story
Clean & More is a glycine-based prophylactic powder containing functionalized tri-calcium phosphate. It is used with commercially available air polishing devices by dental professionals in a clinical setting. The powder is delivered via air stream to the tooth surface to remove subgingival and supragingival plaque-biofilm and stains. Simultaneously, the functionalized tri-calcium phosphate particles mechanically occlude open dentin tubules, providing relief from dentin hypersensitivity. The healthcare provider uses the device during routine prophylaxis or periodontal/periimplant maintenance. The output is a cleaned tooth surface and reduced patient sensitivity, benefiting patients by providing effective cleaning while managing hypersensitivity during the procedure.
## Clinical Evidence
Clinical study (n=40) conducted per ISO 14155:2011 evaluated pain levels and hypersensitivity reduction. Subjects with predetermined hypersensitivity were treated with Clean & More. Hypersensitivity was assessed via air blast and tactile scoring at baseline, post-treatment, 10 days, 4 weeks, 3 months, and 6 months. Results showed statistically significant hypersensitivity relief based on tactile stimuli at 10 days and up to 4 weeks.
## Technological Characteristics
Glycine-based powder containing functionalized tri-calcium phosphate. Operates via mechanical air polishing and dentin tubule occlusion. Biocompatibility assessed per ISO 10993-1, -3, -5, -10, -11 and ISO 7405:2008. No specific standards for prophy powders exist.
## Regulatory Identification
An airbrush is an AC-powered device intended for use in conjunction with articulation paper. The device uses air-driven particles to roughen the surfaces of dental restorations. Uneven areas of the restorations are then identified by use of articulation paper.
## Special Controls
The special control for this device is International Electrotechnical Commission's IEC 60601-1-AM2 (1995-03), Amendment 2, “Medical Electrical Equipment—Part 1: General Requirements for Safety.”

### Device Description
Clean & More is classified as airbrush (21 C.F.R. § 872.6080) because it is a powder to be used with air polishing devices in the professional tooth cleaning.
Clean & More is a prophylactic powder for gentle and professional sub- and supragingival cleaning of teeth, including the removal of plaque-biofilm and stains, using commercially available air polishing devices.
Clean & More is a glycine based air polishing powder containing functionalized tri-calcium phosphate, a substance which blocks open dentin tubules on the tooth surface, thereby contributing to a reduction in dentin hypersensitivity.
### Indications for Use
- · Professional cleaning of teeth: Removal of subgingival plaque-biofilm and stains
- · Professional cleaning of teeth including patients with dentin hypersensitivity
- · Treatment of dentin hypersensitivity by blockage of the dentin tubules
· Can also be used in the presence of fixed orthodontic devices (brackets), restorative and prosthetic materials, and implants
• For maintenance in periodontitis therapy after completion of initial treatment - when using standard devices - for gingival pockets up to 5 mm in depth
· For maintenance in periimplantitis therapy after completion of initial treatment - when using standard devices - for gingival pockets up to 5 mm in depth
{6}------------------------------------------------
## Comparison
Chemical composition, performance, fundamental technology, and intended use of Clean & More have been compared to the predicate devices.
As Clinpro Prophy Powder (K140684, 3M Deutschland GmbH, Germany) and OSspray Cleaning Compound (K062502, OSspray Ltd, London, U.K.), Clean & More is an air polishing powder to be used with air polishing devices in the professional tooth cleaning. Whereas OSspray Cleaning Compound is composed of calcium phosphosilicate compound in powder form, Clean & More and Clinpro Prophy Powder consist of water-soluble amino acid glycine. Like OSspray Cleaning Compound and Vanish Varnish (K092141, by 3M ESPE Dental, USA), Clean & More contains chemical component to block dentin tubules in order to reduce dentinal hypersensitivity.
Comparative testing, both in vitro and in vivo, revealed equivalent results in performance of Clean & More and the predicate device.

Performance Data: Non-clinical Performance Testing
In vitro testing was conducted to examine cleaning effect, plaque removal from bovine enamel, surface roughness of bovine enamel and composite materials, abrasion of bovine enamel and dentin, and removal of plaque-biofilm on zirconia and titanium surfaces comparing the performance of Clean & More to Clinpro Prophy Powder (K140684).
Standards: Not applicable. There are no standards specifically for prophy powders.
The cleaning effect of Clean & More is equal compared to Clinpro Prophy Powder air polishing powder.
Plaque removal from bovine enamel was very efficient with Clinpro Prophy Powder as well as Clean & More. Plaque removal efficiency of Clean & More is comparable to Clinpro Prophy Powder.
Statistical evaluation of the surface roughness data showed no difference in surface roughness of bovine enamel surface after cleaning with Clean & More and Clinpro Prophy Powder.
ANOVA evaluation of observations of composition materials after cleaning with Clean & More and after cleaning with Clinpro Prophy Powder revealed no statistically significant difference in surface roughness.
The abrasion of bovine enamel was minimally detectable for Clean & More and Clinpro Prophy Powder.
The abrasions of bovine dentin caused by Clean & More and Clinpro Prophy Powder were nearly as low as the abrasion on bovine enamel.
Keyence microscope observation revealed a gentle cleaning effect on enamel surface with Clean & More and Clinpro Prophy Powder.
Surface analysis of dentine showed no differences to enamel when using the glycine based air polishing powders: Clean & More and Clinpro Prophy Powder.

### Performance Data: Clinical Study
Effect of Clean & More for professional cleaning of teeth including patients with dentin hypersensitivity and treatment of dentin hypersensitivity has been shown in a Clinical study conducted according to ISO 14155:2011 - Good Clinical Practice (GCP). The objective of the study was to determine pain level during treatment with subsequent reduction of hypersensitivity, and the sustainability of the effect. A total of 40 subjects were enrolled with predetermined hypersensitivity on at least two teeth determined by air blast and tactile scoring. After providing the Clean & More treatment the incidence and degree of dentinal hypersensitivity was again determined after treatment, at 10 days, 4 weeks and 3 and 6 months. Treatment with Clean & More resulted in statistically significant hypersensitivity relief based on tactile stimuli at 10 days and up to 4 weeks.
## Performance Data: Biocompatibility Testing
The biocompatibility of Clean & More has been assessed by a board-certified toxicologist according to recommendations in FDA guidance and internationally recognized standards for medical and dental devices.
The biocompatibility assessment for this product was conducted in accordance with the following Guidance:
l) Testing guidelines outlined in the FDA General Program Memorandum G95. 2) ISO 10993-1:2009(E) Biological evaluation of medical devices - Part I: Evaluation and testing within a risk management process; in addition, relevant detailed guidance in ISO Standards I 0993-3:2003 (Tests for genotoxicity, carcinogenicity and reproductive toxicity), 10993-5:2009 (Tests for in vitro cytotoxicity), 10993-10:2010 (Tests for irritation and skin sensitization); and 1 0993-11:2006 (Tests for systemic toxicity) was considered; 3) ISO 7405:2008 Dentistry -- Evaluation of Biocompatibility of Medical Devices in Dentistry;
# Conclusions
Performance test results from comparative in vitro testing together with results from comparative clinical testing to evaluate reduction in dental hypersensitivity after cleaning using Clean and More and Clinpro Prophy Powder, demonstrate that Clean and More blocks dentin tubules, cleans tooth surfaces and provides relief for patients suffering from dentinal hypersensitivity. The conclusion of the biocompatibility assessments is that Clean & More is safe for its intended use.
# Substantial Equivalence Statement
The contents of this 510(k) premarket notification for Clean & More demonstrate substantial equivalence to the predicate devices for basic composition, fundamental technology, performance, and indications for use. Although the indications are not exactly identical to the predicates this new device incorporates the elements of the primary and reference predicates. Data has been presented for each of these indications. The data and clinical use supports that the inclusion of treatment of hypersensitivity during dental prophylaxis.
