No
Explanation: The device, BioClear Concentrate, is intended to act as an antimicrobial and disinfectant agent for dental unit waterlines, controlling microbial populations. It is not designed to diagnose diseases or conditions in patients.
No
The device is a chemical concentrate intended to be added to a water supply system. It is a physical substance, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to act as a potable, antimicrobial agent in dental unit waterlines to control microbial populations. This is a disinfectant/cleaning function, not a diagnostic one.
- Device Description: The description details the chemical composition and how it's used to treat the water in the dental unit. It doesn't mention any components or processes related to testing biological samples or providing diagnostic information.
- Performance Studies: The performance studies focus on the device's ability to kill bacteria and reduce biofilm, which are measures of its effectiveness as a disinfectant. They do not involve diagnostic metrics like sensitivity, specificity, or AUC related to identifying a disease or condition.
- Predicate Devices: The predicate devices listed (Dentosept I disinfectant and Sirona Water Purification Unit) are also related to disinfection and water purification in a dental setting, not in vitro diagnostics.
In vitro diagnostics are devices used to examine specimens, such as blood, urine, or tissue, from the human body to provide information for the diagnosis, prevention, or monitoring of a disease or condition. The BioClear Concentrate does not perform this function. It is a product used to treat the water supply of a dental unit.

Device Description
The BioClear Concentrate is intended to be added to an independent water supply system reservoir bottle and would act as a constantly present disinfectant agent in the dental operative unit. It has been found to aid in the control of the microbial population in dental unit waterlines. A number of independent water systems can be purchased separately and retrofitted to a pre-existing dental operative unit or can easily be found included on a large number of newer dental operative units and are often referred to as a "clean water" systems. The BioClear Concentrate is composed of 16% Citric Acid. U.S.P./F.C.C. as the only active ingredient. Other GRAS chemicals, 14.3% glucose F.C.C., 0.8% Aspartame F.C.C., and 0.25% Sodium Benzoate F.C.C. ( which only acts as a preservative for the concentrate), and 0,008% FD & C Blue #1, The artificial and natural sweeteners are added only to offer an agreeable flavor. The blue color is added to ensure the BioClear Concentrate has, in fact, been added to the tap water. The BioClear Concentrate would be mixed with tap water in a ratio of 7 ml/ 500 ml +/-0.5ml to produce a final concentration of 0.224% citric acid, and would be changed daily. The dental operative unit should be purged/ flushed for 15 seconds every morning for the first 3 weeks. After this period of time, although recommended, it makes virtually no difference. All of these chemicals are Generally Recognized as Safe (GRAS) as per the FDA,

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
- Clinical and Laboratory studies compared BioClear Concentrate and Dentosept P: Both products were shown to destroy the viability of waterline bacterial biofilms tested. Dentosept P needed to be applied full strength for 24 hours as a sanitizing treatment cycle, while BioClear Concentrate destroyed mature biofilms at its diluted concentration in 7 days of constant contact. BioClear also eliminated biofilm matrix as seen by scanning electron microscopy.
- Time-kill capabilities of BioClear: Demonstrated very rapid kill (10 minute, mean 5 log reduction) of ATCC Pseudomonas aeruginosa, ATCC Escherichia coli, and ATCC Klebstella pneumonta. Kill rates for Staphylococcus aureus were 1 hour.
- Dental school clinical study: Dental units using diluted BioClear Concentrate had no detectable bacterial growth after being left stagnant for 4 weeks. After 2 weeks of use, BioClear Concentrate offered a bacteriostatic potential for up to 3 weeks.
- Safety study (metal analysis): Trace metals were not found to reach health or equipment destruction hazard levels. Zinc levels were higher in the first week but dropped to non-detectable levels. Flushing reduced trace metals.

SUBSTANTIAL EQUIVALENCE
BioClear Concentrate is similar in its intended use and mode of action to the Dentosept I disinfectant, legally marketed by both Pelton & Crane Company, Charlotte, N.C. with their Spirit 1/ 2, K962071 and Siemens Company, Germany, with their Sirona Water Purification Unit, K901672.
However, we feel that BioClear Concentrate is superior to Dentosept P. relative to its technological characteristics, its clinical performance and its safety.

INTENDED USE OF DEVICE
I .ike Dentosept P, BioClear Concentrate is a dental operative unit waterline disinfectant. Both products are diluted ( BioClear == 71.4water/1 BioClear and Dentosept P = 100 water/1 Dentosept P) in tap water ( Dentosept P requires naturally or artificially softened water). This diluted mixture of either disinfectant is placed in an independent water reservoir system which supplies the dental operative unit. Thus, both disinfectants are constantly present in the waterlines and in the water delivered to the patient. Both disinfectants have been shown, in limited clinical and laboratory studies, to destroy the viability of the waterline bacterial biofilms tested ( Dentosept P must not be diluted to accomplish this endpoint). Both of these disinfectants have also been shown, in clinical and laboratory studies, to kill several typical water borne bacteria (Dentosept P, in its diluted form is minimally effective against Pseudomonas). Dentosent P requires periodic "sanitizing treatment cycles". BioClear Concentrate, properly diluted (even in hard water) does not require special treatment cycles and can be left stagmant for one month without a loss of effectiveness.
TECHNOLOGICAL CHARACTERISTICS
Both properly diluted BioClear Concentrate and Dentosept P have been shown, in both limited clinical and laboratory studies, to destroy the viability of waterline bacterial biofilms tested. Dentosept P must be applied full strength to the dental operative unit waterlines for 24 hours, as a "sanitizing treatment cycle", to be effective. In testing, BioClear Concentrate was shown to destroy the viability of mature biofilms, at its diluted concentration, in 7 days of constant contact. BioClear has been further shown, in a laboratory study and a dental school clinical study, to eliminate all the biofilm matrix from the tubing samples examined by scanning electron microscopy, of a wel established biofilm, with disruption seen as early as one week, Because of documented re-contamination with diluted Dentosept P, this 24 hour sanitizing treatment cycle must be repeated periodically throughout the yea relative to bacterial testing results.
BioClear's superiority also relates to its ability to produce 7 log reductions all planktonic bacteria as well as biofilm bacteria tested ( both ATCC and wild type) when tested at only 89% of its recommended concentration. The
3
time kill capabilities of BioClear are most keenly exemplified by its ability for very rapid kill ( 10 minute, mean 5 log reduction) of the ATCC Pseudomonas acruginosa. ATCC Escherichia coli, and ATCC Klebstella pneumonta Variations in rate of kill were linked to the free chlorine levels found in the tap water. Kill rates for Stanhylococcus aureus were 1 hour. This relates to BioClear's mechanism of action. Gram negative bacteria represent the vast majority of water originated bacteria.
Dentosept P's potential for biofilm regrowth relates to its inability to effectively kill Gram negative bacteria in time-kill experiments. Particularly alarming was the continued growth, after 72 hours in contact with the diluted Dentosept P. of Pseudomonas, This information is found in Attachment G. Predicate Device Information.
In a dental school clinical study, dental units utilizing properly diluted BioClear Concentrate were shown to have no bacterial growth detectable after being left stagnant for 4 weeks. This attribute allows the dentist to return to work after a vacation, and begin their practice immediately. BioClear Concentrate, after being utilized for at least 2 weeks, appears to offer the dental operative unit waterlines a bacteriostatic potential for up to 3 week into the future. This means that if a practitioner runs out of BioClear Concentrate for a week or two. their waterlines have been shown to still inhibit bacterial growth. If they utilize sterile water, they have been shown to deliver no bacteria, and if they utilize tap water, they have been shown to deliver water with contamination levels at the same or one log higher levels. This offers a "safety net" to the practitioner and patient should this occur. If Dentosent P treated water is left stagnant in the dental unit waterlines for a week, the dental unit waterlines must have a 24 hour sanitizing treatment cvcle performed to bring the bacterial levels under control.
At a pH of 1.42, the BioClear Concentrate is bacteriocidal, and yeast-cidal. Some molds, like Aspergillus niger which can produce cittic acid, are resistant to very low pH levels. Thus, sodium benzoate (a GRAS chemical which is utilized in the beverage industry to inhibit molds and yeasts) has been added at a percentage of 0.25% to eliminate the mold contamination potential ( this is 7 times greater than the appropriate mycostatic dose at this pH). Repeated mold kill was seen at only 0.1%.

MECHANISM OF ACTION
The active agent in BioClear Concentrate is Citric Acid, while the active agents in Dentosept P are hydrogen peroxide and elemental silver. Citric acid functions as a chelator of divalent ions like Mg+ and Ca++ which bind certain cell wall constituents to the cell wall of Gram negative bacteria. Once the cell wall in compromised, it allows for easy ingress of hypochlorous acid and citric acid as well as allowing for osmotic disruption of the bacterial cell wall and membraue. The second mechanism involves the disruption of bacterial cellular function by chelating out essential ions for enzymatic function. The third mechanism is that of an acid. Citric acid's last pKa is 3.1, at which point 1/2 of the citric acid is in its associated form. Properly diluted BioClear Concentrate has a pH of around 2.82. It is well accepted that an acid, in its associated form, can penetrate the cell wall and membrane and kill the bacteria. The final mechanism relates to the free chlorine found in tap water. Below a pH of 4.1, almost 100% of the free chlorine present will be in the hypochlorous acid form, which is 80 times more gennicidal than the hypochlorite ion form. Citric acid was found to be effective with water hardness levels up to 400 ppm CaCO3 and free chlorine levels as low as 0,0 DDIN.
BioClear concentrate treated dental operative units also appear to posses a bacteriostatic potential into the future, even when only non-treated tap water is present, for up to 3 weeks. The bacteriostatic potential that citric acid offers to dental unit waterlines appears to be related to its binding to the tubing lumen.
Dentosept P utilizes hydrogen peroxide and elemental silver as its active agents. The literature states that hydrogen peroxide functions primarily by the production of hydroxyl radicals, which brings about oxidation of critical systems. Further studies have shown that hydrogen peroxide's effects are 80% reversed by 10mM of Mg+, especially when the percentage of hydrogen peroxide is below 0.1%. Diluted Dentosept P has only 0.0141% hydrogen peroxide. This could be why soft water is required when using Dentosept P. Elemental silver is apparently a bacteriostatic agent and not truly a bacteriocidal agent.

SAFETY
BioClear is made from the active ingredient, Citric Acid, which is a "Generally Recognized as Safe" chemical by the FDA. To this is added other food grade GRAS chemicals like sucrose, aspartame, FD & C Blue #1 and sodium benzoate ( at a final diluted concentration of only 0.0035%) . The final diluted citric acid concentration is only 0.224%, which is slightly more concentrated than 7-up® (0.144%) and much less concentrated than lemonade ( 1.0 -1.1%).
Metal analysis of the treated water showed that no trace metals were found to reach levels which would pose a health hazard or an equipment destruction hazard. For the first week. Zinc levels were higher ( 0.750 mg/ 0.522 mg in the overnight 16ml draw) but these levels dropped to non-detectable levels on the third and fifth week because the surface atoms had been oxidized/ chelated out. Trace metals were found to reach their highest levels ( still considered to be non-detectable) after being left stagnant overnight. Flushing the lines for about 15- 30 seconds was found to reduce the trace metals to levels below the source water content for the first 3 weeks. After this three week period. the flushing cycles appears to offer virtually no difference. Dental plastics and rubbers are resistant to high concentrations of citric acid.
Dentosept P is made from hydrogen peroxide diluted to 0,0141%, and elemental silver, diluted to 0.25 mg/liter ( 0.25 ppm). Although the hydrogen peroxide is probably safe in its diluted form, elemental silver raises questions. Only 5 rats were fed Dentosept P for one week for the toxic effect study. No log term heavy metal analysis was performed, and no study was performed relative to oral tattooing, argyria, on dental patients,
SUMMARY
Because of its intended use, as a dental waterline disinfectant agent, and its mode of action, as an agent constantly present in the dental operative unit waterlines, we feel that BioClear Concentrate is substantially equivalent to Dentosept P. We also feel that duc to the technological characteristics, mechanism of action and well documented safety, BioClear Concentrate is substantially equivalent or an improvement over the comparative legally marketed Dentosept P.
